Hey Bill Nye! How Much Energy Would It Take to Power a Time Machine?
Bill Nye the Science Guy tackles the perennially challenging topic of time travel. Whether we can ultimately travel through time may depend on the speed of our yet-to-be-invented time machine.
Bill Nye, scientist, engineer, comedian, author, and inventor, is a man with a mission: to help foster a scientifically literate society, to help people everywhere understand and appreciate the science that makes our world work. Making science entertaining and accessible is something Bill has been doing most of his life. In Seattle Nye began to combine his love of science with his flair for comedy, when he won the Steve Martin look-alike contest and developed dual careers as an engineer by day and a stand-up comic by night. Nye then quit his day engineering day job and made the transition to a night job as a comedy writer and performer on Seattle's home-grown ensemble comedy show “Almost Live." This is where “Bill Nye the Science Guy®" was born. The show appeared before Saturday Night Live and later on Comedy Central, originating at KING-TV, Seattle's NBC affiliate. While working on the Science Guy show, Nye won seven national Emmy Awards for writing, performing, and producing. The show won 18 Emmys in five years. In between creating the shows, he wrote five children's books about science, including his latest title, “Bill Nye's Great Big Book of Tiny Germs." Nye is the host of three currently-running television series. “The 100 Greatest Discoveries" airs on the Science Channel. “The Eyes of Nye" airs on PBS stations across the country. Bill's latest project is hosting a show on Planet Green called “Stuff Happens." It's about environmentally responsible choices that consumers can make as they go about their day and their shopping. Also, you'll see Nye in his good-natured rivalry with his neighbor Ed Begley. They compete to see who can save the most energy and produce the smallest carbon footprint. Nye has 4,000 watts of solar power and a solar-boosted hot water system. There's also the low water use garden and underground watering system. It's fun for him; he's an engineer with an energy conservation hobby. Nye is currently the Executive Director of The Planetary Society, the world's largest space interest organization.
Emre: Hi Bill Nye. My name is Emre. I thought of a time machine that basically ran on all the data based on your brain, so it basically calculated all the information on your brain and all the data in your life and it would create a vortex, which you would go back through and you would go back in time, so it's a time machine. Now I was thinking that if you went back once you would have the memory of going back so that would create another vortex in which you would go through again and once you got to the dimension, which was in the past, the other time machine, with your memory, would, because you're the person, it would also form another vortex, which you'd go through and you keep going through infinite vortexes until you were lost and come in infinite space and time. Now, my question is would it be possible to generate enough electricity to be able to create another vortex, which would accelerate time and bring you and generate enough power to bring you back, all the way back to your time and keep it stable with the time machine and you? So could you please answer that?
Bill Nye: Well, of course. It's just a very straightforward question. What? So one of the old problems, Emre? Is that right? Emre, one of the old problems, in all the science-fiction stories that involve time travel is can you go back in time and change things so that you didn't exist? Can you go back in time and change things so that by the time it's now, you're fabulously wealthy? Can you go back in time and change things so that the world is completely different and better? Or can you go back in time and accidentally screw everything up? These are old questions in science fiction. And I got to say so far no, you can't. However, recently, by recently in the last 10 years, some physicists, and the way I remember this — these guys were in Japan — showed that you could build a time machine if you are allowed to travel near the speed of light in this time machine in a big circle and you could only go back in time to when the machine was built; this is in theoretical physics. However, in order to go faster or as close to the speed of light you need enormous amounts of energy and it might stretch you where your head is being accelerated more than your feet and it would kill you maybe. These are great questions. And I noticed you use the word vortex a lot. A vortex is a whirlpool like; the center of a hurricane is a vortex and when the water goes down the drain in the bathtub, that's a vortex. And there is a fabulous thing I hope you learn about in a whole discipline called fluid mechanics, the mechanisms by which fluid flows, called vorticity.
Vorticity is a fabulous word. So I appreciate you throwing around the word vortex, but I'm not sure it's exactly what you mean when you're talking about time travel. But think about it, can you go back in time and change things so that you never existed? It's an old question in science fiction and it's cool, but as far as anybody knows, time only goes one way. And as far as anybody knows, nobody knows why that is. Going back in time is really hard and it's related to this thing that has to do with heat. Heat always spreads out. Heat never spontaneously concentrates on its own; by spontaneous I mean on its own without influence. In the example I'll give you, go all over the world, look at everything you're ever everything to look at; look at a glass of water; look at a lake; look at a pond; they never just freeze in the summertime. It never happens. They heat doesn't go down to the bottom of the pond or up into the atmosphere and then freezes on its own. Energy always spreads out and when something spreads out, it's moving over a distance over time. So time and the spreading out of energy are intimately connected or closely related and there's something about that that keeps us from building time machines. Carry on.
Bill Nye takes on the sticky science of time travel as imagined by science-fiction writers. While we don't have any solid leads on a time machine, Japanese physicists have shown that time travel is theoretically possible if you travel in a ship at the speed of light. There are two restrictions: (1) You could only travel back in time to the point at which the ship you're traveling in was created and (2) the amount of energy required to power the machine, enough to get the craft to the speed of light, could stretch your body such that, well, it's not a happy ending, says Nye.

A socially minded franchise model makes money while improving society.
- A social enterprise in California makes their franchises affordable with low interest loans and guaranteed salaries.
- The loans are backed by charitable foundations.
- If scaled up, the model could support tens of thousands of entrepreneurs who are currently financially incapable of entering franchise agreements.
The underdog challenging McDonald’s & Wall Street | Hard Reset by Freethink www.youtube.com
Social responsibility is becoming a major focus of many businesses. While turning a profit is always the ultimate goal — nobody can eat good intentions, after all — having a positive impact on society is becoming an equally important goal.
A restaurant chain in California, already focused on providing healthy food at a competitive cost, is testing a new way to create more entrepreneurs. Specifically, it is working with charitable foundations to provide business opportunities to those who normally would not have access.
When a company wants to expand without paying all of the upfront costs itself or taking on the entire risk of operating in a new market, it can enter into a franchise agreement with an entrepreneur. In exchange for a share of the profits (as well as some fees and adherence to certain quality standards), the entrepreneur — now a franchisee — can open their own branch of a larger brand. The entrepreneur enjoys the benefits of owning a business, while the brand owner can cash in on intellectual property.
This model is wildly successful. There is a reason you can find fast food joints like McDonald's everywhere from Times Square to Prague (next to the Museum of Communism, no less). According to the International Franchise Association, there were more than 733,000 franchised business establishments in the United States in 2018, accounting for nearly 3 percent of GDP.
The franchise model — in which a local agent keeps some earnings while handing over a portion to a central authority — isn't new. Indeed, variations have been around since the Middle Ages, though it only took off after WWII. Franchising is now a recognized system in many countries and is used in all manner of industries, including restaurants, pet supply stores, automotive repair shops, hotels, and even senior care.
The Catch-22: you have to spend money to make money
The biggest problem with franchising is the high cost of becoming a franchisee.
While the costs vary, opening a restaurant as a franchisee can easily cost $500,000. A franchise car repair shop can require $250,000, and opening a hotel under a franchise's banner can set a person back millions. In some cases, the franchiser also will set a minimum net worth requirement or insist that the money that pays their fees not be borrowed. Even if a person can find a way around that, most new businesses do not turn a profit for quite some time after opening. These limitations essentially rule out all but the wealthy from becoming a franchisee.
As a result, there are some social enterprises that are looking to make franchising more accessible to the less affluent.
As a business that hopes to rapidly expand, they looked to franchising. However, the idea of seeking out a bunch of rich people to support a business like theirs struck CEO Sam Polk as out of step with its vision. So, the company came up with a better idea.
Their Social Equity Franchise Program helps tenured Everytable employees open their own franchise locations through free training and assistance in securing low interest loans to finance the store. To help the entrepreneurs survive the difficult early years, participants in the program are assured an income of $40,000 in their first three years of operations. Repayments on the loans do not begin until after the business is turning a profit.
The capital for all these low interest loans comes from a number of foundations such as the California Wellness Foundation (Cal Wellness). Foundations like these are required to give away a small portion of their endowments every year on causes aligned with their missions. However, most of the rest of it is simply invested in the stock market to assure the endowment continues to exist.
People like Cal Wellness CEO Judy Belk have begun to invest that money elsewhere, like in loans to provide the money needed to open an Everytable franchise. As she explained to FreeThink:
"Cal Wellness and many other foundations are saying, 'I think we can do a little better with that [money]. Why not use that capital to invest in the communities that we're supposed to serve?'"
In the end, Everytable gets a new restaurant that expands the brand, foundations get returns on their investment, and the franchisee gets an opportunity that they likely never would have had without the program.
Expanding the Everytable model
If even a small share of the $2 trillion foundations in the U.S. have are invested into this sort of social cause, tens of thousands of loans could be given to those less affluent people who are looking to start a business. While this model likely would lower returns to institutional investors like charities, they could enjoy more tangible results in the communities they exist to serve. According to a report published by the Federal Reserve Bank of Atlanta, local entrepreneurship increases income and employment and decreases poverty.
At the individual level, this would help a lot of people who otherwise never would be able to seriously consider going into business for themselves. By a number of measures, business owners make more than wage workers and can also claim ownership of the assets that comprise the business. Beyond that, many small business owners enjoy the non-financial benefits of their position as well, including the independence and autonomy that often come with business ownership.
When working optimally, good business is good for society.
Fintech companies are using elements of video games to make personal finance more fun. But does it work, and what are the risks?
- Gamification is the process of incorporating elements of video games into a business, organization, or system, with the goal of boosting engagement or performance.
- Gamified personal finance apps aim to help people make better financial decisions, often by redirecting destructive financial behaviors (like playing the lottery) toward positive outcomes.
- Still, gamification has its risks, and scientists are still working to understand how gamification affects our financial behavior.
- YouTube www.youtube.com
The human brain is a pretty lazy organ. Although it's capable of remarkable ingenuity, it's also responsible for nudging us into bad behavioral patterns, such as being impulsive or avoiding difficult but important decisions. These kinds of short-sighted behaviors can hurt our finances.
However, they don't hurt the video game industry. In 2020, video games generated more than $179 billion in revenue, making the industry more valuable than sports and movies combined. A 2021 report from Limelight Network found that gamers worldwide spend an average of 8 hours and 27 minutes per week playing video games.
Good at gaming, bad at saving
It's not necessarily bad that Americans spend millions of dollars and hours on video games. But consider another set of statistics: 25 percent of Americans have no retirement savings at all, while roughly half are either living "on the edge" or "paycheck to paycheck," according to a recent report on the Financial Resilience of Americans from the FINRA Education Foundation. Meanwhile, experts predict that Social Security funds could dry up by 2035.
So, why don't people save more? After all, the benefits of compounding interest aren't exactly a secret: Investing a few hundred bucks every month would make most people millionaires by retirement if they start in their twenties. However, the recent FINRA report found that many Americans have alarmingly low levels of financial literacy, a topic that's not taught in most public schools.
Even for the financially literate, saving money is psychologically difficult
But what if we could infuse the instant gratification of video games into our long-term financial habits? In other words, what if finance looked less like an Excel spreadsheet and more like your favorite video game?
A growing number of finance applications are making that a reality. By using the same strategies video game designers have been optimizing for decades, gamifying personal finance could be one of the most efficient ways to help people save for the future while reaping instant psychological rewards. But it doesn't come without risks.
What is gamification?
In simple terms, gamification takes the motivating power of video games and applies it to other areas of life. The global research company Gartner offers a slightly more technical definition of gamification: "the use of game mechanics and experience design to digitally engage and motivate people to achieve their goals."
The odds are you have encountered gamification already. It's utilized by many popular apps, websites, and devices. For example, LinkedIn displays progress bars representing how much profile information you have filled out. The Apple Watch has a "Close Your Rings" feature that shows how many steps you need to walk to meet your daily goal.
Brands have used gamification to boost customer engagement for decades. For example, McDonald's launched its Monopoly game in 1987, which essentially attached lottery tickets to menu items, while M&M's gained consumer attention with Eye-Spy Pretzel, an online scavenger hunt game that went viral in 2010.
In addition to marketing, gamification is used in social media, fitness, education, crowdfunding, military recruitment, and employee training, just to name a few applications. The Chinese government has even gamified aspects of its Social Credit System, in which citizens perform or refrain from various activities to earn points that represent trustworthiness.
Finance is arguably one of the best-suited fields for gamification. One reason is that financial data can be easily measured and graphed. Perhaps more importantly, financial decisions occur in the background of almost everything we do in modern life, from deciding what we eat for lunch to where we are going to spend our lives.
Gamification doesn't just make boring stuff fun; it's also an effective way to change our behavior. Used properly, it can also disrupt our habits.
The nature of habits
It's tempting to think that we make our way through life by thoughtfully considering the information before us and making sensible choices. That's not really the case. Research suggests that about 40 percent of our daily activities are performed out of habit, a term the American Journal of Psychology defines as a "more or less fixed way of thinking, willing, or feeling acquired through previous repetition of a mental experience."
In other words, we spend much of our lives on autopilot. From an evolutionary perspective, it makes sense that we rely on habits: our brains require a lot of energy, especially when we're faced with tough decisions and complex problems, like financial planning. It's relatively easy to rely on learned behavioral patterns that provide a quick, reliable solution. However, those patterns don't always serve our long-term interests.
Saving money is a good example. Imagine you have $500 with which to do whatever you want. You could invest it. Or you could go on a shopping spree. Unfortunately, the brain doesn't process these two options the same way; in fact, it actually processes the investing option as something like a pain stimulus.
Why gamification works
Saving is painful. But can't people simply choose to be more financially responsible? In short: Yes, but it takes a lot of effort. After all, when it comes to changing behavior, willpower is only part of the equation.
Some psychologists think willpower is a finite resource, or that it's like an emotion whose motivational power ebbs and flows based on what's happening around us. For example, you might establish a monthly budget and stick to it for a couple weeks. But then you get stressed. The next time you're out shopping, you might find it harder to resist making an impulsive purchase in your stressed-out state.

"A growing body of research shows that resisting repeated temptations takes a mental toll," the American Psychological Association writes. "Some experts liken willpower to a muscle that can get fatigued from overuse." In the terminology of psychology, this is called ego depletion.
Gamification offers a way to outsource your willpower. That's because games offer psychological rewards that can motivate us to perform certain actions that might otherwise have seemed too boring, taxing, or emotionally draining. What's more, gamifying parts of your life is less of a change of mind and more of a change of environment.
A 2017 study published in Computers in Human Behavior noted that "enriching the environment with game design elements, as gamification does by definition, directly modifies that environment, thereby potentially affecting motivational and psychological user experiences."
The study argued that games are most motivational when they address three key psychological needs: competence, autonomy, and social relatedness. It's easy to imagine how games can tap into these categories. For competence, games can feature badges and performance graphs. For autonomy, games can offer customizable avatars. And for social relatedness, games can feature compelling storylines and multiplayer gameplay.
Gamification and the brain
Games can motivate us by satisfying our psychological needs and giving us a sense of reward. From a neurological perspective, this occurs through the release of "feel-good" neurotransmitters, namely dopamine and oxytocin.
"Two core things have to happen in the brain to influence your decision-making," Paul Zak, a neuroscientist and professor of economic sciences at Claremont Graduate University, told Big Think. "The first is you have to attend to that information. That's driven by the brain's production of dopamine. The second thing, you've got to get my lazy brain to care about the outcomes. And that caring is driven by emotional resonance. And that's associated with the brain's production of oxytocin."

When released simultaneously, these neurotransmitters can put us into a state that Zak calls "neurologic immersion." In this state, our everyday habits have less control over our behavior, and we're better able to take deliberate action. It's an idea Zak and his colleagues developed over two decades of using brain-imaging technology to study the nature of extraordinary experiences.
As he wrote in an article published by the World Experience Organization, neurologic immersion can occur when experiences, including video games, are unexpected, emotionally charged, narrowing one's focus to the experience itself, easy to remember, and provoking actions.
"The components of the extraordinary come as a package, not in isolation from each other," Zak wrote. "It's the 'action' part that is key to finding immersion. Extraordinary experiences cause people to take an action, whether it's donating to charity, buying a product, posting on social media, or returning to enjoy an experience again."
Games can invoke these types of immersive experiences.. But how exactly are financial organizations using gamification to help people "level up" their financial futures?
Gamifying personal finance
Banks and financial companies have been using gamification for years. What started with simple concepts, like PNC Bank's "Punch the Pig" savings feature, has evolved into a diverse field of games that are helping people stick to budgets, save money, and pay off debt.
What's surprising about the gamification of personal finance is that some of the most successful apps are redirecting destructive financial behaviors, like buying lottery tickets, toward positive outcomes. One example is an app called Long Game, which uses an approach called "lottery savings."
"People actually really love the lottery," Lindsay Holden, co-founder and CEO of Long Game, told Big Think. "The lottery today is a $70-billion-dollar industry in the U.S., and the people that are buying lotto tickets are the people that least should be buying lotto tickets. And so how can we redirect that spend into something that's helping them in their lives?"
Long Game's answer is to encourage users to make automatic or one-time investments into a prize-linked savings account. As users make investments, they earn coins that can be used to play games, some of which offer cash prizes. But unlike the real lottery, the prize money comes from banks that are partnered with Long Game, meaning users can't lose their principal investment.
Blast is a savings app aimed at traditional gamers. The platform lets users connect a savings account to their video game accounts. Users then set performance goals in the video games, such as killing a certain number of enemies. Accomplishing these goals triggers a pre-selected investment into the savings accounts. In addition to earning interest, users can also win prize money by accomplishing certain missions or placing high on public leaderboards.
"Gamers tell us they feel better with the time they spend gaming when they know they are micro-saving or micro-earning in the background," Blast co-founder and CEO Walter Cruttenden said in a statement.

Fortune City takes a different approach to gamified finance. The app encourages users to track their spending habits, which are represented by visually appealing graphs. As users log expenses, they're able to build buildings in their own virtual city. The expense categories match the types of buildings users can construct; for example, buying food lets users construct a restaurant. It's like "SimCity" meets certified public accountant.
The risks of gamification
Gamifying your finances might help you save money, but it doesn't come without risks. After all, receiving extrinsic rewards when we perform a behavior can affect our intrinsic motivation to repeat that behavior both positively and negatively. It's a phenomenon called the overjustification effect.
In addition, gamified finance apps can also be addictive and encourage risky financial behavior. Robinhood, for example, uses visually appealing performance metrics and lottery-like game elements to incentivize the trading of stocks and cryptocurrencies. But while investing in these assets might be a good financial decision for some people, Robinhood arguably encourages its users to be "players" in the difficult world of trading, not necessarily rational investors.
What's more, gamification doesn't seem to work for everyone.
"From social psychology and behavioural economics, we know that the most likely [result of] gamification [is that you] will motivate some people, will demotivate other people, and for a third group there'll be no effect at all," noted a 2017 study on gamification and mobile banking published in Internet Research.
But given that 14.1 million Americans are unbanked, and millions more struggle with financial literacy, it's reasonable to think that gamified finance apps could help many people work toward financial independence.
"One of the most interesting things we've found is that people want help when it comes to making difficult decisions," Zak told Big Think. "In my view, any app that helps you be a more effective saver is probably a good app. But I think we have to do a lot more work to really understand the underlying neuroscience of gamification. And so we need to continue to design games that teach you more about how to 'level up in life,' not just level up in the game."
"You dream about these kinds of moments when you're a kid," said lead paleontologist David Schmidt.
- The triceratops skull was first discovered in 2019, but was excavated over the summer of 2020.
- It was discovered in the South Dakota Badlands, an area where the Triceratops roamed some 66 million years ago.
- Studying dinosaurs helps scientists better understand the evolution of all life on Earth.
David Schmidt, a geology professor at Westminster College, had just arrived in the South Dakota Badlands in summer 2019 with a group of students for a fossil dig when he received a call from the National Forest Service. A nearby rancher had discovered a strange object poking out of the ground. They wanted Schmidt to take a look.
"One of the very first bones that we saw in the rock was this long cylindrical bone," Schmidt told St. Louis Public Radio. "The first thing that came out of our mouths was, 'That kind of looks like the horn of a triceratops.'"
After authorities gave the go-ahead, Schmidt and a small group of students returned this summer and spent nearly every day of June and July excavating the skull.

"We had to be really careful," Schmidt told St. Louis Public Radio. "We couldn't disturb anything at all, because at that point, it was under law enforcement investigation. They were telling us, 'Don't even make footprints,' and I was thinking, 'How are we supposed to do that?'"
Another difficulty was the mammoth size of the skull: about 7 feet long and more than 3,000 pounds. (For context, the largest triceratops skull ever unearthed was about 8.2 feet long.) The skull of Schmidt's dinosaur was likely a Triceratops prorsus, one of two species of triceratops that roamed what's now North America about 66 million years ago.

The triceratops was an herbivore, but it was also a favorite meal of the Tyrannosaurus rex. That probably explains why the Dakotas contain many scattered triceratops bone fragments, and, less commonly, complete bones and skulls. In summer 2019, for example, a separate team on a dig in North Dakota made headlines after unearthing a complete triceratops skull that measured five feet in length.
Michael Kjelland, a biology professor who participated in that excavation, said digging up the dinosaur was like completing a "multi-piece, 3-D jigsaw puzzle" that required "engineering that rivaled SpaceX," he jokingly told the New York Times.

The Badlands aren't the only spot in North America where paleontologists have found dinosaurs. In the 1870s, Colorado and Wyoming became the first sites of dinosaur discoveries in the U.S., ushering in an era of public fascination with the prehistoric creatures — and a competitive rush to unearth them.
Since, dinosaur bones have been found in 35 states. One of the most fruitful locations for paleontologists has been the Morrison formation, a sequence of Upper Jurassic sedimentary rock that stretches under the Western part of the country. Discovered here were species like Camarasaurus, Diplodocus, Apatosaurus, Stegosaurus, and Allosaurus, to name a few.

As for "Shady" (the nickname of the South Dakota triceratops), Schmidt and his team have safely transported it to the Westminster campus. They hope to raise funds for restoration, and to return to South Dakota in search of more bones that once belonged to the triceratops.
Studying dinosaurs helps scientists gain a more complete understanding of our evolution, illuminating a through-line that extends from "deep time" to present day. For scientists like Schmidt, there's also the simple joy of coming to face-to-face with a lost world.
"You dream about these kinds of moments when you're a kid," Schmidt told St. Louis Public Radio. "You don't ever think that these things will ever happen."
Playing video games could help you make better decisions about money.
- The word is out on gaming—it's not just something that children do for fun anymore. Games are tools that can be used to teach new skills, reduce stress, and even change behaviors by triggering chemical reactions in the brain.
- These benefits and more have provided scientists and developers with a promising path forward. "Games reduce the stress of making decisions," says neuroscientist and professor Paul Zak. "App designers have now used game structures to help people learn new information, make new decisions; and one of the most exciting applications is in financial decision making."
- But simply turning something into a game isn't enough to see meaningful changes in habits. Developers of gamified apps like Long Game have found ways to combine the engaging and fun experience we expect from video games, with something that has traditionally not been very fun: saving money.
