Neutron Stars: The Most Extreme Objects in the Universe
We’ve traveled to lots of weird places on this show - from the interiors of black holes to the time before the big bang. But today I want to take you on a journey to what has got to be the weirdest place in the modern universe - a place...

What If Black Holes ARE Dark Energy?
We tend to imagine there are connectings between things that we don’t understand. Quantum mechanics and consciousness, aliens and pyramids, black holes and dark matter, dark matter and dark energy, dark energy and black holes. Usually...

How To See Black Holes By Catching Neutrinos
Neutrinos are one of the most bizarre of known particles. Black holes are probably the most bizarre of astrophysical objects. Makes sense we should use one to study the other, no? Well, today we’re doing just that.

How Does Gravity Escape A Black Hole?
Fact: in a black hole, all of the mass is concentrated at the singularity at the very center. Fact: every black hole singularity is surrounded by an event horizon. Nothing can escape from within the event horizon unless it can travel...

How To Build The Universe in a Computer
We routinely simulate the universe on all of its scales, from planets to large fractions of the cosmos. Today we’re going to see how it’s possible to build a universe in a computer - and see whether there’s a limit to what we can simulate.

How To Simulate The Universe With DFT
If you used every particle in the observable universe to do a full quantum simulation, how big would that simulation be? At best a large molecule. That’s how insanely information dense the quantum wavefunction really is. And yet we...

What Happens If A Black Hole Hits Earth?
The possibility that a black hole could actually impact Earth may seem straight out of science fiction, but the reality is that microscopic primordial black holes could actually hit Earth. If one did, it wouldn't just impact like an...

New Results in Quantum Tunneling vs. The Speed of Light
Paradoxically, the most promising prospects for moving matter around faster than light may be to put a metaphorical brick wall in its way. New efforts in quantum tunneling - both theory and experiment - show that superluminal motion may...

Why Magnetic Monopoles SHOULD Exist
What happens if you cut a bar magnetic in half? We get two magnets, each with their own North and South poles. But what happens if you keep on cutting, into fourths and eighths and sixteenths and so on? Will we ever get to a single pole?...

The NEW Crisis in Cosmology
I have good news and bad news. Bad news first: two years ago we reported on the Crisis in Cosmology. Since then, it’s only gotten worse. And actually, the good news is also that the crisis in cosmology has actually gotten worse, which...

Navigating with Quantum Entanglement
We often think of quantum mechanics as only affecting only the smallest scales of reality, with classical reality taking over at some intermediate level. But in his 1944 book, What is Life?, the quantum physicist Erwin Schrödinger...

The Supernova At The End of Time
Good news everyone: it looks like the universe is going to end with a series of catastrophic explosions. The very, very long story short is that the universe ends in heat death, as it approaches maximum entropy, and its eternal...

Dissolving an Event Horizon
Black hole singularities break physics - fortunately, the universe seems to conspire to protect itself from their causality-destroying madness. At least, so says the cosmic censorship hypothesis. Only problem is many physicists think it...

Does Quantum Immortality Save Schrödinger's Cat?
To quote eminent scientist Tyler Durden: "On a long enough timeline, the survival rate for everyone drops to zero." Actually… not necessarily true. If the quantum multiverse is real there may be a version of you that lives forever. If we...

Why We Might Be Alone in the Universe
Why does it appear, that humanity is the lone intelligence in the universe? The answer might be that planet Earth is more unique than we've previously assumed. The rare earth hypothesis posits exactly this - that a range of factors made...

How Many States Of Matter Are There?
Let’s talk about states of matter. You know your states of matter don’t you? We have solids, liquids and gasses, and plasmas, quark-gluon plasmas, nuclear matter, bose-einstein condensates, neutronium, time crystals, and sand. Come to...

The Weight of “Nothing” Could Mean Everything (to Physics)
Deep in a Sardinian mine, researchers are constructing an experiment that hopes to solve what's known as The Worst Prediction In The History of Physics, and pin down the true identity of dark energy.
