How to SEE or HEAR the Big Bang

Adults Physics
So you know a bit about the Big Bang - but did you know that you can physically see or hear it in your every day life? Find out how 'static' often contains remnants from this monumental event.

The beginning of the universe, for beginners

Adults Physics
How did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.

What Color is the Universe?

Adults Physics
When you stare up at the night sky, you might think that the universe is really black, but that's just because our eyes aren't sensitive enough to see the billions and billions of multicolored stars out there. Ever wonder why certain stars are certain colors? And what color is our sun, really? If we looked at enough stars, could we figure out the average color of the universe?

How fast & how far do bullets go?

Adults Physics
James May imparts his wisdom on all things bullets.

Dark matter: The matter we can't see

Adults Physics
The Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the universe. CERN scientist James Gillies tells us what accounts for the remaining 96% (dark matter and dark energy) and how we might go about detecting it.

If superpowers were real: Super speed

Adults Physics
What if super speed wasn't just the stuff of epic comic book stories? Is it scientifically possible to be super speedy? In this series, Joy Lin tackles six superpowers and reveals just how scientifically realistic they can be to us mere mortals.

How Big is the Solar System?

Adults Physics
The true scale of our cosmic neighborhood. Whoa.

Project Loon - Google's Internet Balloons - Future Thinking - Head Squeeze

Adults Physics
We are becoming increasingly more dependent on the internet to help run our lives. But much of the planet is outside the web, zones that are without web coverage. Ordinarily, this is more of a nuisance than a calamity. But in the aftermath of disasters, restoring internet coverage can be the difference between life and death.

The fundamentals of space-time: Part 2 - Andrew Pontzen and Tom Whyntie

Adults Physics
Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.

Why is glass transparent?

Adults Physics
If you look through your glasses, binoculars or a window, you see the world on the other side. How is it that something so solid can be so invisible? Mark Miodownik melts the scientific secret behind amorphous solids.

There's No Such Thing As Cold

Adults Physics
You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's NOT there. In this week's video, learn the difference between heat and temperature, why a wind makes us feel colder, and what it's like to live as a mass of jiggling atoms. This is the physics of cold.

Quantum Entanglement & Spooky Action at a Distance

Adults Physics
Does quantum entanglement make faster-than-light communication possible?

How Tall Can Mountains Be?

Adults Physics
What is the maximum height for a mountain on Earth!? And why?

Astronauts Grow a Water Bubble in Space

Adults Physics
During Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman - along with European Space Agency astronaut Alexander Gerst - explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew "submerged" a sealed GoPro camera into a floating ball of water the size of a softball and recorded the activity with a 3-D camera.

Brian Cox visits the world's biggest vacuum chamber

Adults Physics
Watch a bowling ball and a feather fall in the giant vacuum chamber. A simple experiment but it's really amazing.
