Every astronomy textbook tells us that soon after the Big Bang, there was a period of exponentially accelerating expansion called cosmic inflation. In a tiny fraction of a second, inflationary expansion multiplied the size of the...

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...

Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces. But some extremely subtle clues in nature have led us to believe that the forces of nature were...

Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean and what are the incredible implications this fact has upon our reality? To find out check out this episode of Space Time...

Causality is meant to move in one direction: forward. But the Quantum Eraser experiment seems to reverse causality. How and why can this happen and what are the implications of this experiment on how we understand Quantum Mechanics and...

The discovery of the Higgs boson ten years ago in the Large Hadron Collider was the culmination of decades of work and the collaboration of 1000s of brilliant and passionate people. It was the final piece needed to confirm the standard...

It’s about time we discussed an obscure concept in physics that may be more fundamental than energy and entropy and perhaps time itself. That’s right - the time has come for Action.

I don’t want to alarm you, but the world is going to end. All of this. Gone. And scientists are certain all of this will happen. On the bright side this isn’t going to happen for 4-5 billion years. It makes me wonder: In a universe...

Scientists at the Large Hadron Collider may have just discovered a new fundamental particle that could change the way we look at the universe. Is this Dark Energy? A giant Neutrino? The big brother of the Higgs Boson? Or could it be the...

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.<br/>

Mildred Dresselhaus was a giant in the field of nanoscience. She didn't invent anything you have in your home right now, but she made it possible for us to have self-charging phones, smarter refrigerators, and more.

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.

In the hunt for life beyond Earth, scientists shouldn't skip over frozen planets. In some cases, ice might actually help life evolve!

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

Hank profiles this year's Nobel laureates in science, whose achievements have helped us understand questions as small as how our cells transport materials, and as big as why matter exists at all.

Hank describes how non-Newtonian fluids can save lives - and dreams of a bulletproof hoodie.

Hank shares some developments in cancer research, from new insights into the behavior of zombie cancer cells, to a new method that uses nanotechnology to kill cancer from within.

This year's end News episode wraps up with nothing but superlatives: the biggest, oldest, first, last, smallest and hottest developments in science from 2012.

If you're lucky enough to find a glowing rock, it likely doesn't mean you're the chosen one. In fact, it could have to do with one of these five phenomena! Learn about the quantum mechanics of glowing rocks in this new SciShow Episode...

Ovens are great for baking, cooking, and.... discovering quantum mechanics? In this fascinating episode of SciShow, Hank takes you through the science of quantum mechanics, and how ovens played a big part in their discovery.

The laws of thermodynamics are cornerstones of physics - but one of them is more breakable than it appears. Hosted by: Olivia Gordon

Researchers have made some unexpected readings of mysterious particles called muons, which may make us reexamine the Standard Model in physics.

The weak force has been causing trouble for a century, ruining everything physicists thought was true. But it might actually be responsible for your very existence.
