Gravitational Lensing: What It Is And How It Is Helping Us Discover New Galaxies
Gravitational lensing occurs when a huge amount of matter, like a star, galaxy, or cluster of galaxies, creates a powerful gravitational field around it, strong enough to bend the light coming from distant galaxies (behind them). Roots...

Star and Galaxy Formation in the Early Universe
Okay, so we are about 150 million years into the lifetime of the universe. We've got a bunch of hydrogen and helium and not much else. But then gravity takes over, and boom! We've got stars! How, you ask? Well you'd better watch this!

Gravity Assist: Freaky Physics on the Space Station, with Ethan Elliott
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 .

Warped Spacetime, Gravitational Lensing, and Gravitational Waves (Corroborating General Relativity)
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....

What Exactly is Spacetime? Explained in Ridiculously Simple Words
Spacetime, as a concept, is related to a space that consists of 4 dimensions instead of the regular 3-dimensional space. As early as 1905, Einstein proposed a now widely popular theory that the speed of light is independent of the motion...
