Escape to a Parallel Universe
Card: How might the universe end?
Michio Kaku: Well, when we try to look at the whole universe itself -- many people ask the question, "Well Professor, how do you know -- how do you know that the universe is expanding? How do you know that it came from a big bang? How can you project so far into the future, billions to trillions of years into the future? Well one way we do this is by looking at the Doppler shift. Now, the doppler shift is something that even children are familiar with. When children play "Star Wars" with each other, they go err, err, err with their rocket ships. Right? Well, what makes that err, sound? It's the Doppler effect. When a car moves toward you, the pitch is higher, when the car moves away from you the pitch is lower. And it sounds like this. Eee err. We've all heard it. Same thing with starlight. When yellow light moves toward you, it turns greenish and bluish. When the yellow light moves away from you it turns reddish.
Now, how can you memorize this? Well, I was reading a paper a few years ago and I read this fascinating story of a high school physics teacher who got a speeding ticket for running a red light. The physics teacher went to the blackboard and said, "Your Honor. My car was moving toward a yellow light. Light is compressed in a forward direction when you move toward it, and therefore it turned green. This is the Doppler shift," he said. And he went to the black board and he correctly wrote down all the equations of the Doppler shift. And then this high school physics teacher said, "Your Honor. I do not deserve a traffic ticket." Well, the judge scratched his head and according to the article, the judge said, "Well, I guess there is a law higher than the state of New Jersey, and these are the laws of physics." But then, according to the article, there was a high school kid in the court room and he raised his hand and he said, "Your Honor, I'm just a high school kid, but I happen to be in his high school physics class and he just taught this a couple of weeks ago that this only happens when you approach the speed of light." End of article.
To this day, I still don't know what happened to that poor high school kid. But I tell my students, that if I'm ever in court arguing a speeding ticket or red light, they better not raise their hand if they know what's good for them and they know what's good for their grade.
So, when we look in the heavens, we look at starlight emitted from distant galaxies and we find that the light is slightly reddish. Redder than it's supposed to be. That means that these objects, the gigantic galaxies are moving away from us and therefore the universe is expanding. Well, we could run the video tape backwards, and by running the video tape backwards we could then calculate when all these galaxies came from a single point. And that's how we calculate the age of the universe, by simply hitting the rewind button when we calculate the expansion of the universe.
So by running the video tape backwards, we see that the universe is about 13.7 billion years old, plus or minus 1%. So, we now know the age of the universe. 13.7 billion years by running the video tape backwards. But what happens if we hit fast forward. What happens if we go forward in time billions of years? Well, here it gets murkier. But by analyzing how the universe has been expanding in the past, we used to think that the universe is slowing down. We used to think the universe is aging and therefore it's slowing down; running out of steam. Wrong. We now believe that the universe is speeding up. It's actually accelerating, in runaway mode which means that in stead of dying in a big crunch, we'll probably die in a big freeze. We're not positive. We don't know if this will keep on going for billions of years. But if so, the universe is in a runaway mode. It means that one day, perhaps when we look at the night sky; perhaps we'll see almost nothing because the distant galaxies are so far that light cannot even reach our telescopes. Not a pleasant thought. But our universe may eventually die in a big freeze rather than a big crunch.
Card: How soon would this scenario most likely take place?
Michio Kaku: Nobody knows when this big freeze will take place, or if it will ever take place. However, estimates have been made, perhaps hundreds of billions of years, perhaps trillions of years. One day it will get so cold that you'll look at the night sky and it will be almost totally black. All the stars will have exhausted all of their nuclear fuel, the universe will consist of neutron stars, dead black holes, the temperature will reach near absolute zero, and at that point even consciousness, even thought itself, cannot exist. and some people think that perhaps the laws of physics are a death warrant to all intelligent life; that we're all going to die when the universe freezes over.
But you know, there's a loophole. There's a loophole in the laws of physics. you see, trillions of years from now, perhaps intelligent life will be able to master what is called, "The Planck Energy." The Planck Energy is the ultimate energy. It's the energy of the Big Bang. It's the energy at which gravity itself begins to breakdown.
You know that if you have a microwave oven and you heat it up, you can take ordinary water and make it boil; ice can melt, water can boil. But what happens if you crank up that microwave oven even more? Eventually the steam starts to break up into oxygen and hydrogen. If you crank it up some more, all of a sudden ions form; atoms themselves begin to rip apart. And then if you crank up that microwave oven even more, then even the nucleus begins to break apart and you get a plasma of protons and neutrons. You crank it up some more and you get a gluon plasma. And if you crank it some more to this incredible energy. Ten to the 19 billion electron volts, we're not sure, but perhaps even space itself begins to boil. Even space time becomes unstable. Bubbles begin to form at this Planck Energy. And perhaps these bubbles are gateways. Gateways to a parallel universe.
Of course, we're not sure about this. This pure speculation, but there are theories that say that there could be universes right next to our universe. And in fact, the Large Hadron Collider will give us the first experimental evidence about the existence of parallel universes.
So, think of us a ants living on a sheet of paper, but perhaps there are other parallel sheets of paper with other ants living on them. And perhaps we are very close to these other universes, but we can't reach them. The energy necessary to reach a parallel universe would be the Planck Energy, 10 to the 19 billion electron volts.
I would suppose that trillions of years from now, intelligent life, facing the ultimate demise of the universe itself might decide to leave the universe. To leave our universe and enter a parallel universe in the same way that Alice entered the looking glass to enter Wonderland.
Like many physicists, Michio Kaku thinks our universe will end in a "big freeze." Unlike many physicists, he thinks we might be able to avoid this fate by slipping into a parallel universe "in the same way that Alice entered the looking glass to enter Wonderland."

The COVID-19 pandemic is making health disparities in the United States crystal clear. It is a clarion call for health care systems to double their efforts in vulnerable communities.
- The COVID-19 pandemic has exacerbated America's health disparities, widening the divide between the haves and have nots.
- Studies show disparities in wealth, race, and online access have disproportionately harmed underserved U.S. communities during the pandemic.
- To begin curing this social aliment, health systems like Northwell Health are establishing relationships of trust in these communities so that the post-COVID world looks different than the pre-COVID one.
COVID-19 deepens U.S. health disparities<p>Communities on the pernicious side of America's health disparities have their unique histories, environments, and social structures. They are spread across the United States, but they all have one thing in common.</p><p>"There is one common divide in American communities, and that is poverty," said <a href="https://www.northwell.edu/about/leadership/debbie-salas-lopez" target="_blank">Debbie Salas-Lopez, MD, MPH</a>, senior vice president of community and population health at Northwell Health. "That is the undercurrent that manifests poor health, poor health outcomes, or poor health prognoses for future wellbeing."</p><p>Social determinants have far-reaching effects on health, and poor communities have unfavorable social determinants. To pick one of many examples, <a href="https://www.npr.org/2020/09/27/913612554/a-crisis-within-a-crisis-food-insecurity-and-covid-19" target="_blank" rel="noopener noreferrer">food insecurity</a> reduces access to quality food, leading to poor health and communal endemics of chronic medical conditions. The U.S. Centers for Disease Control and Prevention has identified some of these conditions, such as obesity and Type 2 diabetes, as increasing the risk of developing a severe case of coronavirus.</p><p>The pandemic didn't create poverty or food insecurity, but it exacerbated both, and the results have been catastrophic. A study published this summer in the <em><a href="https://link.springer.com/article/10.1007/s11606-020-05971-3" target="_blank">Journal of General Internal Medicine</a></em> suggested that "social factors such as income inequality may explain why some parts of the USA are hit harder by the COVID-19 pandemic than others."</p><p>That's not to say better-off families in the U.S. weren't harmed. A <a href="https://voxeu.org/article/poverty-inequality-and-covid-19-us" target="_blank" rel="noopener noreferrer">paper from the Centre for Economic Policy Research</a> noted that families in counties with a higher median income experienced adjustment costs associated with the pandemic—for example, lowering income-earning interactions to align with social distancing policies. However, the paper found that the costs of social distancing were much greater for poorer families, who cannot easily alter their living circumstances, which often include more individuals living in one home and a reliance on mass transit to reach work and grocery stores. They are also disproportionately represented in essential jobs, such as retail, transportation, and health care, where maintaining physical distance can be all but impossible.</p><p>The paper also cited a positive correlation between higher income inequality and higher rates of coronavirus infection. "Our interpretation is that poorer people are less able to protect themselves, which leads them to different choices—they face a steeper trade-off between their health and their economic welfare in the context of the threats posed by COVID-19," the authors wrote.</p><p>"There are so many pandemics that this pandemic has exacerbated," Dr. Salas-Lopez noted.</p><p>One example is the health-wealth gap. The mental stressors of maintaining a low socioeconomic status, especially in the face of extreme affluence, can have a physically degrading impact on health. <a href="https://www.scientificamerican.com/index.cfm/_api/render/file/?method=inline&fileID=123ECD96-EF81-46F6-983D2AE9A45FA354" target="_blank" rel="noopener noreferrer">Writing on this gap</a>, Robert Sapolsky, professor of biology and neurology at Stanford University, notes that socioeconomic stressors can increase blood pressure, reduce insulin response, increase chronic inflammation, and impair the prefrontal cortex and other brain functions through anxiety, depression, and cognitive load. </p><p>"Thus, from the macro level of entire body systems to the micro level of individual chromosomes, poverty finds a way to produce wear and tear," Sapolsky writes. "It is outrageous that if children are born into the wrong family, they will be predisposed toward poor health by the time they start to learn the alphabet."</p>Research on the economic and mental health fallout of COVID-19 is showing two things: That unemployment is hitting <a href="https://www.pewsocialtrends.org/2020/09/24/economic-fallout-from-covid-19-continues-to-hit-lower-income-americans-the-hardest/" target="_blank" rel="noopener noreferrer">low-income and young Americans</a> most during the pandemic, potentially widening the health-wealth gap further; and that the pandemic not only exacerbates mental health stressors, but is doing so at clinically relevant levels. As <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7413844/" target="_blank" rel="noopener noreferrer">the authors of one review</a> wrote, the pandemic's effects on mental health is itself an international public health priority.

Northwell Health coronavirus testing center at Greater Springfield Community Church.
Credit: Northwell Health<p>Novel coronavirus may spread and infect indiscriminately, but pre-existing conditions, environmental stressors, and a lack of access to care and resources increase the risk of infection. These social determinants make the pandemic more dangerous, and erode communities' and families' abilities to heal from health crises that pre-date the pandemic.</p><p>How do we eliminate these divides? Dr. Salas-Lopez says the first step is recognition. "We have to open our eyes to see the suffering around us," she said. "Northwell has not shied away from that."</p><p>"We are steadfast in improving health outcomes for our vulnerable and underrepresented communities that have suffered because of the prevalence of chronic disease, a problem that led to the disproportionately higher death rate among African-Americans and Latinos during the COVID-19 pandemic," said Michael Dowling, Northwell's president and CEO. "We are committed to using every tool at our disposal—as a provider of health care, employer, purchaser and investor—to combat disparities and ensure the <a href="https://www.northwell.edu/education-and-resources/community-engagement/center-for-equity-of-care" target="_blank" rel="noopener noreferrer">equity of care</a> that everyone deserves." </p><p>With the need recognized, Dr. Salas-Lopez calls for health care systems to travel upstream and be proactive in those hard-hit communities. This requires health care systems to play a strong role, but not a unilateral one. They must build <a href="https://www.northwell.edu/news/insights/faith-based-leaders-are-the-key-to-improving-community-health" target="_blank" rel="noopener noreferrer">partnerships with leaders in those communities</a> and utilize those to ensure relationships last beyond the current crisis. </p><p>"We must meet with community leaders and talk to them to get their perspective on what they believe the community needs are and should be for the future. Together, we can co-create a plan to measurably improve [community] health and also to be ready for whatever comes next," she said.</p><p>Northwell has built relationships with local faith-based and community organizations in underserved communities of color. Those partnerships enabled Northwell to test more than 65,000 people across the metro New York region. The health system also offered education on coronavirus and precautions to curb its spread.</p><p>These initiatives began the process of building trust—trust that Northwell has counted on to return to these communities to administer flu vaccines to prepare for what experts fear may be a difficult flu season.</p><p>While Northwell has begun building bridges across the divides of the New York area, much will still need to be done to cure U.S. health care overall. There is hope that the COVID pandemic will awaken us to the deep disparities in the US.</p><p>"COVID has changed our world. We have to seize this opportunity, this pandemic, this crisis to do better," Dr. Salas-Lopez said. "Provide better care. Provide better health. Be better partners. Be better community citizens. And treat each other with respect and dignity.</p><p>"We need to find ways to unify this country because we're all human beings. We're all created equal, and we believe that health is one of those important rights."</p>
Shannon Lee shares lessons from her father in her new book, "Be Water, My Friend: The Teachings of Bruce Lee."
- Bruce Lee would have turned 80 years old on November 27, 2020. The legendary actor and martial artist's daughter, Shannon Lee, shares some of his wisdom and his philosophy on self help in a new book titled "Be Water, My Friend: The Teachings of Bruce Lee."
- In this video, Shannon shares a story of the fight that led to her father beginning a deeper philosophical journey, and how that informed his unique expression of martial arts called Jeet Kune Do.
- One lesson passed down from Bruce Lee was his use and placement of physical symbols as a way to help "cement for yourself this new way of being, or this new lesson you've learned." By working on ourselves (with the right tools), we can develop the skills necessary to rise and conquer new challenges.
How to deal with "epistemic exhaustion."
Melting ice is turning up bodies on Mt. Everest. This isn't as shocking as you'd think.
- Mt. Everest is the final resting place of about 200 climbers who never made it down.
- Recent glacial melting, caused by climate change, has made many of the bodies previously hidden by ice and snow visible again.
- While many bodies are quite visible and well known, others are renowned for being lost for decades.
Why leave the bodies there at all? Why not bring people down as soon as they die?<p>It costs a lot of money to go get a body on the highest mountain in the world, up to $80,000 to be <a href="https://people.com/human-interest/dead-bodies-mount-everest-glaciers-melt/" target="_blank">precise</a>. Then there is the problem of actually doing it, since some attempts to retrieve bodies are forced by difficult conditions to abandon their efforts.</p><p>Some people, such as mountaineer <a href="http://www.alanarnette.com/" target="_blank">Alan Arnette</a>, argue that the bodies should be left there. He told the BBC, "Most climbers like to be left on the mountains if they died. So it would be deemed disrespectful to just remove them unless they need to be moved from the climbing route or their families want them."</p> This doesn't stop people from wanting the bodies taken down or dealt with in other ways. <a href="https://en.wikipedia.org/wiki/David_Sharp_(mountaineer)" target="_blank">David Sharp</a>'s body was moved out of sight in 2007. <a href="https://en.wikipedia.org/wiki/George_Mallory" target="_blank">George Mallory'</a>s body took 75 years to find and was given an Anglican burial in 1999. Over time, the elements often move bodies away from the main routes up the mountain to more isolated areas where they remain undisturbed.
Everest’s chilling landmarks<div class="rm-shortcode" data-media_id="V4Kz3Zfc" data-player_id="FvQKszTI" data-rm-shortcode-id="9959d7e5b2866ad9f61ab823a5b60cbf"> <div id="botr_V4Kz3Zfc_FvQKszTI_div" class="jwplayer-media" data-jwplayer-video-src="https://content.jwplatform.com/players/V4Kz3Zfc-FvQKszTI.js"> <img src="https://cdn.jwplayer.com/thumbs/V4Kz3Zfc-1920.jpg" class="jwplayer-media-preview" /> </div> <script src="https://content.jwplatform.com/players/V4Kz3Zfc-FvQKszTI.js"></script> </div> <p>The bodies that remain in view are often used as waypoints for the living. Some of them are well-known markers that have earned <a href="https://www.ranker.com/list/creepy-stories-about-deaths-and-dead-bodies-on-mount-everest/sabrina-ithal" target="_blank">nicknames</a>. </p><p> For instance, the image above is of "<a href="https://en.wikipedia.org/wiki/Green_Boots" target="_blank">Green Boots</a>," the unidentified corpse named for its neon footwear. Widely believed to be the body of Tsewang Paljor, the remains are well known as a guide point for passing mountaineers. Perhaps it is too well known, as the climber David Sharp died next to Green Boots while dozens of people walked past him — many presuming he was the famous corpse. </p><p>A large area below the summit has earned the discordant nickname "Rainbow Valley" for being filled with the bright and colorfully dressed corpses of maintainers who never made it back down. The sight of a frozen hand or foot sticking out of the snow is so common that Tshering Pandey Bhote, vice president of Nepal National Mountain Guides Association claimed: "Most climbers are mentally prepared to come across such a sight."</p><p>Other bodies are famous for not having been found yet. Andrew "Sandy" Irvine, the climbing partner of George Mallory, may have been one of the first two people to reach the summit of Everest a full 30 years before Edmund Hillary and Tenzing Norgay did it. Since they never made it back down, nobody knows just how close to the top they made it. </p><p>Mallory's frozen body was found by chance in the '90s without the Kodak cameras he brought up to record the climb with. It has been speculated that Irvine might have them and <a href="https://web.archive.org/web/20130303001517/http://www.velocitypress.com/Mallory__Irvine.html#A127_Film" target="_blank">Kodak </a>says they could still develop the film if the cameras turn up. Circumstantial evidence suggests that they died on the way back down from the summit, Mallory had his goggles off and a photo of his wife he said he'd put at the peak wasn't in his coat. If Irvine is found with that camera, history books might need rewriting. </p><p>As Everest's glaciers melt its morbid history comes into clearer view. Will the melting cause old bodies to become new landmarks? Will Sandy Irvine be found? Only time will tell. </p>
A strange object found in Utah desert has prompted worldwide speculation about its origins.
- A monolithic object found in a remote part of Utah caused worldwide speculation about its origins.
- The object is very similar to the famous monolith from Stanley Kubrick's "2001: Space Odyssey".
- The object could be work of an artist or even have extraterrestrial origins.
1. ART OBJECT<p>Chances are, this is an art object. The shiny "monolith" appears to be bolted to the ground and made of metal. It also seems to be fastened with rivets, rather being a uniform block of more unexplainable production origin. Deserts are great places for unusual art installations as has been evidenced by art projects you can discover wondering through the desert ghost towns and faraway canyons of Nevada, California, Utah and New Mexico. Certainly, an artist with a sense of humor and an appreciation of Kubrick's genius could have installed such "sculpture" in hopes of exactly what is happening right now – viral fame.</p><p>On the other hand, there is evidence, courtesy of eagle-eyed <a href="https://www.reddit.com/r/news/comments/jzkpad/helicopter_pilot_finds_strange_monolith_in_remote/gdg9qfi?utm_source=share&utm_medium=web2x&context=3" target="_blank">Google Earth sleuths</a>, that the object appeared in that location (somewhere near <a href="https://www.nps.gov/cany/index.htm" target="_blank" rel="noopener noreferrer">Canyonlands National Park</a>) in 2015-2016. So it's possibly been there for a few years. Would an artist have placed it there so long ago with the aim of having this type of success eventually?</p><p>A gallery owner <a href="https://www.9news.com.au/world/utah-monolith-desert-mystery-solved-john-mccracken-sculptor-artist-2001-a-space-odyssey/0bae1a27-5bd2-451e-90a6-393928d9ed02" target="_blank">claimed</a> the work may be a tribute to the art of the late artist John McCracken, who created similar-looking objects before he died in 2011. McCracken was part of the Light and Space movement with such artists as James Turrell, and was known to make his sculptures from plywood forms that were coated with fiberglass and polyester resin.</p><p>While the theory that the monolith was the work of a McCracken aficionado (or the artist himself) may hold some water due to the object's similarity, the fact that the artist died so long ago and the lack of clear incentive for anyone to have planted this years ago only to reveal it now work against this theory.</p>
