Actually… not necessarily true. If the quantum multiverse is real there may be a version of you that lives forever.Hosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo Scholzer, Yago Ballarini, and Pedro OsinskiDirected by: Andrew KornhaberExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0QIf we can’t ever peer into these other realities that are used to explain quantum mechanics, how do we know they exist? In order to understand what happens to those different branches, and to understand why we find ourselves in one of them, we need to embrace one of the interpretations of quantum mechanics. For example the Copenhagen interpretation, which says that the wavefunction branches that we don’t observe somehow vanish at the moment of measurement. Or the Many Worlds interpretation, which states that those other branches are just as valid as ours - implying that reality may split and multiply in all possible ways. In that case we only see one branch because we live in that branch, and the others are rendered inaccessible by decoherence. But today I’m going to offer a test. Admittedly NOT a very useful one - but one that’s fun to think about. We’ll call this test quantum immortality. It’s based on the famous Schrodinger’s cat thought experiment.

It's as though this thing - electric charge - is as fundamental a property of an object as its mass. It just sort of ... is. Well it turns out if you dig deep enough, the fundamental-ness of charge unravels, and in many things, including mass itself, are unraveled with it.Sign Up on Patreon to get access to the Space Time Discord!https://www.patreon.com/pbsspacetimeCheck out the Space Time Merch Storehttps://www.pbsspacetime.com/shopSign up for the mailing list to get episode notifications and hear special announcements!https://mailchi.mp/1a6eb8f2717d/spacetimeHosted by Matt O'DowdWritten by Fernando Franco Félix and Matt O'Dowd Post Production by Leonardo Scholzer, Yago Ballarini, Pedro Osinski, Adriano Leal and Stephanie FariaGFX Visualizations: Ajay ManuelDirected by Andrew KornhaberAssistant Producer: Setare GholipourExecutive Producers: Eric Brown and Andrew KornhaberExecutives in Charge (PBS): Adam Dylewski, Maribel Lopez Director of Programming (PBS): Gabrielle Ewing Spacetime is produced by Kornhaber Brown for PBS Digital Studios.This program is produced by Kornhaber Brown, which is solely responsible for its content.© 2021 PBS.

First, Einstein’s relativity utterly changed the way we think about space, time, motion and gravity. Then the quantum revolution of the 20s and 30s overturned all of our intuitions about the subatomic world. Together, general relativity and quantum mechanics have allowed us to explain nearly every fundamental phenomenon observed, and have predicted many unexpected phenomena that have since been verified. And yet the two theories contradict each other in fundamental ways. In the century since that golden era of physics, we’ve been trying to reconcile the two … without success. But today on space-time I’m going to begin our discussion of the great quest for this union – the quest for a theory of quantum gravity, and for a theory of everything.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangAnton LifshitsCoolAsCatsDavid NicklasFabrice EapQuasarDean FuquaMark RosenthalMayank M.

The result of absolute gravitational collapse of a massive body: a point of hypothetical infinite density surrounded by an event horizon. At that horizon time is frozen and the fabric of space itself cascades inwards at the speed of light. Nothing can travel faster than light, and so nothing can escape from below the event horizon- not matter, not light, not even information.

Don’t get me wrong; the math is complicated. But the objects themselves are simple. In fact every black hole in the universe, no matter how it formed or what happened to it afterwards, can be perfectly described with only three properties. Those properties are mass, angular momentum, and electric charge. Or at least this is the proposition behind the famous no-hair conjecture, or no-hair theorem.

In his essay “The Unreasonable Effectiveness of Mathematics”, the physicist Eugine Wigner said that “the enormous usefulness of mathematics in the natural sciences is something bordering on the mysterious”. This statement was inspired by the observation that so many aspects of the physical world seem to be describable and predictable by mathematical equations to incredible precision especially as quantum phenomena. But quantum phenomena have no subjective qualities and have questionable physicality. They seem to be completely describable by only numbers, and their behavior precisely defined by equations. In a sense, the quantum world is made of math. So does that mean the universe is made of math too? If you believe the Mathematical Universe Hypothesis then yes. And so are you.
