Spacetime on its smallest scales is a seething ocean of black holes and wormholes flickering into and out of existence—or so many physicists think has to be the case. But why should we take this spacetime foam seriously if we’ve never...

So you’ve decided to jump into a black hole. Good news: as long as the black hole is big enough you can sail through the event horizon without harm and get to experience the interior of the black hole before you’re annihilated by the...

When a theory makes a prediction that disagrees with an experimental test, sometimes it means we should throw the theory away. But what if that theory has otherwise produced the most successful predictions in all of physics? Then, that...

If we ever want to simulate a universe, we should probably learn to simulate even a single atomic nucleus. But it’s taken some of the most incredible ingenuity of the past half-century to figure out how that out. All so that today I can...

Sometimes our mathematical hacks point to strange new aspects of reality. For example Max Planck used a quantization trick to figure out the spectrum of light emitted by hot objects. The quantization part of his math trick was meant to...

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...

It's the most famous prediction of perhaps the most famous genius of our time ... Stephen Hawking's theory of Hawking Radiation.

It turns out that "nothing" is one of the most interesting somethings in all of physics.

Hank responds to viewer questions, and explains what the Higgs boson particle actually IS.

Let me tell you a story about virtual particles. It may or may not be true.

How does a force between particles work? What causes an attraction or repulsion? Why does electromagnetism and gravity have infinite range, but the strong and weak force have a small range? Quantum chromodynamics...

It’s one of the biggest mysteries in science. It makes up the majority of the universe. What is dark energy? What is dark energy made of? What is quintessence? Is Dark energy the cosmological constant?...

Ask 10 physicists what a particle is: you'll get 10 different answers. Quantum mechanics showed via the Schrodinger equation, that quantum objects are not particles but waves smeared out in space, until the moment...

What came before the Big Bang? what happened before the big bang? Since time is thought to have started at the big bang, asking what happened "before" is like asking what is North of the North pole? It may have no...

SUMMARY:

Why are we here? Why is there something instead of nothing. Part of the answer is rooted in physics. Matter is not the simplest thing there could have been. The simplest thing In physics is...

SUMMARY:

Quantum field theory or QFT is the basis of the best theory we have in physics today to explain nearly everything, called the Standard Model of particle physics. What is Quantum Field theory? Why is it...

SUMMARY

Hawking Radiation DOES'NT Work the Way Hawking Explained it! Here's the Reality...Hawking Radiation: The Oversimplified Picture vs. The Reality...Hawking radiation suggested that black holes are not...

The universe is expanding, but why? Dark Energy might be the key in solving this mystery.

Escaping the inescapable. Hawking Radiation, Quantum Fields and Black Holes.

Get ready for one of the weirdest things in modern physics. Particles that pop into existence from nothing and then go back to nothing again! This is happening all the time, all around you and even inside of you. It's the quantum foam,...

View "Beyond Einstein: Part II" at:Albert Einstein's theories rank among humanity's greatest achievements. They sparked the scientific revolution of the 20th Century. In their attempts to understand how space, time and matter are...

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's...
