Hey Bill Nye! Do Laws of Math Apply near Black Holes and the Edge of Space?
Calculus was invented by Isaac Newton in the middle of the 17th century, so does a historically contingent event hold true everywhere in the universe, even near black holes? Bill Nye the Science Guy replies to a Big Think fan.
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.
Thomas: My name is Thomas and I'm from Los Angeles California and I was wondering if mathematics is truly universal? I'm not disputing it I'm just really wondering if mathematics, such as calculus, really like is the same near the edges of the universe? For all that we know or like near black holes because do mathematical laws breakdown? Thanks.
Bill Nye: Thomas, that is a great question about mathematics. As far as we know it works everywhere. Now, if we go to a place, as you suggested near a black hole, the edge of the universe, and mathematics doesn't work, we would say to ourselves well there's just mathematics that we don't understand and we have to add some more math to our canon of mathematical equations. It's very reasonable that there's math that's nobody knows how it works, but just understand that when it comes to the motion of planets, when it comes to how rockets work, when it comes to the paths of comets and asteroids and meteors, we understand this stuff inside out. However, it was only in the 1600s that these discoveries were made and so you'll also hear people talk all the time about the singularity. The singularity. And this to me is when you get one over zero. And one over zero is infinite, or it is unknowable. And I'll give you an example.
What's one thousandth? What's bigger one tenth or one thousandth? A tenth is bigger than a thousandth. Okay. Then what's bigger, one thousandth or one the thousandths? A thousandth is bigger. All right, now what about one over one ten thousandth? That's the thousand. But one over one millionth is a million. One over a billionth is one billion. So as the number get smaller and smaller the total, the inverse, the denominator causes the quantity to become bigger. And so if it's over zero it would become infinity or infinite, and nobody knows what happens at infinity. No one knows what's happens exactly at the singularity. Oh people speculate, but as near as we can tell math applies everywhere. That is a great question. Thank you.
Calculus was invented by Isaac Newton in the middle of the 17th century, so does a historically contingent event hold true everywhere in the universe, even near black holes and at the edge of outer space? Yes, as far we know, mathematical laws are universal, says Bill Nye the Science Guy. Since the invention of calculus, we have come to know the movement of planets, asteroids, comets, etc. with highly accurate detail. And we can predict their movement regardless of where they are in the universe.
It is at least possible, however, that our present mathematical canon is insufficient to describe events everywhere in outer space. But that would mean that current laws were incomplete, not that they were wrong or failed to be universal. Humans are always adding to current mathematical models, and it's conceivable that major new mathematical discoveries have yet to be made. One such discovery may relate to "the singularity," or one divided by zero.
The result of this division is either unknowable or infinite, depending on your preference, says Bill Nye. In this video clip, he explains a series of mathematical problems that demonstrate how counterintuitive numbers can be, and how speculative their conclusions can become.
A plan to forgive almost a trillion dollars in debt would solve the student loan debt crisis, but can it work?
- Sen. Elizabeth Warren has just proposed a bold education reform plan that would forgive billions in student debt.
- The plan would forgive the debt held by more than 30 million Americans.
- The debt forgiveness program is one part of a larger program to make higher education more accessible.
Researchers hope the technology will further our understanding of the brain, but lawmakers may not be ready for the ethical challenges.
- Researchers at the Yale School of Medicine successfully restored some functions to pig brains that had been dead for hours.
- They hope the technology will advance our understanding of the brain, potentially developing new treatments for debilitating diseases and disorders.
- The research raises many ethical questions and puts to the test our current understanding of death.
The image of an undead brain coming back to live again is the stuff of science fiction. Not just any science fiction, specifically B-grade sci fi. What instantly springs to mind is the black-and-white horrors of films like Fiend Without a Face. Bad acting. Plastic monstrosities. Visible strings. And a spinal cord that, for some reason, is also a tentacle?
But like any good science fiction, it's only a matter of time before some manner of it seeps into our reality. This week's Nature published the findings of researchers who managed to restore function to pigs' brains that were clinically dead. At least, what we once thought of as dead.
What's dead may never die, it seems
The researchers did not hail from House Greyjoy — "What is dead may never die" — but came largely from the Yale School of Medicine. They connected 32 pig brains to a system called BrainEx. BrainEx is an artificial perfusion system — that is, a system that takes over the functions normally regulated by the organ. The pigs had been killed four hours earlier at a U.S. Department of Agriculture slaughterhouse; their brains completely removed from the skulls.
BrainEx pumped an experiment solution into the brain that essentially mimic blood flow. It brought oxygen and nutrients to the tissues, giving brain cells the resources to begin many normal functions. The cells began consuming and metabolizing sugars. The brains' immune systems kicked in. Neuron samples could carry an electrical signal. Some brain cells even responded to drugs.
The researchers have managed to keep some brains alive for up to 36 hours, and currently do not know if BrainEx can have sustained the brains longer. "It is conceivable we are just preventing the inevitable, and the brain won't be able to recover," said Nenad Sestan, Yale neuroscientist and the lead researcher.
As a control, other brains received either a fake solution or no solution at all. None revived brain activity and deteriorated as normal.
The researchers hope the technology can enhance our ability to study the brain and its cellular functions. One of the main avenues of such studies would be brain disorders and diseases. This could point the way to developing new of treatments for the likes of brain injuries, Alzheimer's, Huntington's, and neurodegenerative conditions.
"This is an extraordinary and very promising breakthrough for neuroscience. It immediately offers a much better model for studying the human brain, which is extraordinarily important, given the vast amount of human suffering from diseases of the mind [and] brain," Nita Farahany, the bioethicists at the Duke University School of Law who wrote the study's commentary, told National Geographic.
An ethical gray matter
Before anyone gets an Island of Dr. Moreau vibe, it's worth noting that the brains did not approach neural activity anywhere near consciousness.
The BrainEx solution contained chemicals that prevented neurons from firing. To be extra cautious, the researchers also monitored the brains for any such activity and were prepared to administer an anesthetic should they have seen signs of consciousness.
Even so, the research signals a massive debate to come regarding medical ethics and our definition of death.
Most countries define death, clinically speaking, as the irreversible loss of brain or circulatory function. This definition was already at odds with some folk- and value-centric understandings, but where do we go if it becomes possible to reverse clinical death with artificial perfusion?
"This is wild," Jonathan Moreno, a bioethicist at the University of Pennsylvania, told the New York Times. "If ever there was an issue that merited big public deliberation on the ethics of science and medicine, this is one."
One possible consequence involves organ donations. Some European countries require emergency responders to use a process that preserves organs when they cannot resuscitate a person. They continue to pump blood throughout the body, but use a "thoracic aortic occlusion balloon" to prevent that blood from reaching the brain.
The system is already controversial because it raises concerns about what caused the patient's death. But what happens when brain death becomes readily reversible? Stuart Younger, a bioethicist at Case Western Reserve University, told Nature that if BrainEx were to become widely available, it could shrink the pool of eligible donors.
"There's a potential conflict here between the interests of potential donors — who might not even be donors — and people who are waiting for organs," he said.
It will be a while before such experiments go anywhere near human subjects. A more immediate ethical question relates to how such experiments harm animal subjects.
Ethical review boards evaluate research protocols and can reject any that causes undue pain, suffering, or distress. Since dead animals feel no pain, suffer no trauma, they are typically approved as subjects. But how do such boards make a judgement regarding the suffering of a "cellularly active" brain? The distress of a partially alive brain?
The dilemma is unprecedented.
Setting new boundaries
Another science fiction story that comes to mind when discussing this story is, of course, Frankenstein. As Farahany told National Geographic: "It is definitely has [sic] a good science-fiction element to it, and it is restoring cellular function where we previously thought impossible. But to have Frankenstein, you need some degree of consciousness, some 'there' there. [The researchers] did not recover any form of consciousness in this study, and it is still unclear if we ever could. But we are one step closer to that possibility."
She's right. The researchers undertook their research for the betterment of humanity, and we may one day reap some unimaginable medical benefits from it. The ethical questions, however, remain as unsettling as the stories they remind us of.
In most states, LGBTQ Americans have no legal protections against discrimination in the workplace.
- The Supreme Court will decide whether the Civil Rights Act of 1964 also applies to gay and transgender people.
- The court, which currently has a probable conservative majority, will likely decide on the cases in 2020.
- Only 21 states and the District of Columbia have passed laws effectively extending the Civil Rights of 1964 to gay and transgender people.
