The laws of physics get very, very weird in the realm of particles too small for the eye to see. Aboard the International Space Station, an experiment called the Cold Atom Laboratory (CAL) is exploring how the universe works .

We learned a bit about general relativity and the curvature of spacetime, both earlier in this series, as well as in the modern physics course. But let's talk a bit more about the astronomical observations that corroborate this theory....

Can a close look at the universe give us solutions to problems too difficult even for a planet-sized computer to solve? Physicist Stephen Jordan considers this question and more in our latest video.

Lesson 7 (Circular Motion) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this video:...

Part 2 of the press conference announcing the first direct detection of gravitational waves -- February 11, 2016. The press conference continued after the live webcast concluded. See the remainder here for the first time.

Tipler Cylinders? Wormholes? Ring Lasers? Is it possible to travel BACK in time? In this action packed episode, Dom is hunted down by a government agent who wants to know how he made a time machine.

In this episode: Fertilizer from poultry waste, ancient shark in 3D, an intelligent desk, WIFIRE, solar superstorms, Alaska Fire and Ice, what you never learned about mass, and more!

We think space and time are the structure of the universe. Yet Einstein argued 'space and time are modes by which we think and not conditions in which we live'. And philosophers, Kant and Heidegger, saw space and time as the framework of...

Panelists Sheperd S. Doeleman, founding director of the Event Horizon Telescope (EHT), which produced the first image of a black hole, and Michael Johnson, astrophysicist, Harvard-Smithsonian Center for Astrophysics, answer questions...

A dwarf star in the Musca constellation has so much mass that it measurably distorts space and time. <br/>

The History of Physics (Part 2)

What if the universe had a higher dimensional twist in it?

We've gone through some of the main advancements in modern physics, which brings us to the here and now! What are physicists currently working on? One huge area of interest is developing a quantum field theory for the gravitational...

Astronomers have seen light from BEHIND a black hole for the first time. I explained the discovery and results to my editor, Levi. Congrats to D. Wilkins and the astronomy team!

The Mathematics of our Universe

Dr. Brandon Reddell discusses astrophysics, cosmology, and the science behind the Alpha Magnetic Spectrometer (AMS), an experiment looking for evidence of antimatter and dark matter in the cosmos. This is part one of a three-part series...

View "Beyond Einstein: Part I" 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...

Isaac Newton and Albert Einstein collide in this explanation of two theories of gravity, to the tune of "Defying Gravity" from the musical "Wicked"

A portion of our culture distrusts the scientific method, assuming that there are transcendent truths unknowable by science. But nothing is truly out of bounds for science. If it's real, it can be studied, and tested. Perhaps the...

Relativity comes in different flavors, as it happens. We spent some time looking at special relativity, so now it's time for the general variety. This is all about the geometry of spacetime, which curves around massive objects. This was...
