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...

Food & Fiction: Memorable Meals in Literature | PBS Digital Studios
Food varies wildly from place to place and from culture to culture; since humans are such sensory creatures, using words to evoke the experience of eating is an excellent way to bring a text to life. Hosted by Lindsay Ellis Written by...

The de Broglie Equation and Why There Is No Wave-Particle Duality
The wave-particle duality seems to used all the time to explain quantum mechanics to the public, but it is one of my pet peeves. It represents an outmoded way of thinking (old quantum theory), which is replaced by our current...

I Visited the First Gravitational Wave Detector! LIGO | STELLAR
We’ve been waiting to verify the existence of Gravitational Waves for over 100 years and I actually got to go to LIGO to see exactly how they proved it! I know, this video is a bit different from most Physics Girl videos. It's part of a...

Is randomness in quantum theory an illusion?
God does not play dice with the universe' Einstein famously argued. Yet contemporary physics embeds just such dice playing at the core of its account. Is the universe really unknowable even to itself? Or as Einstein implied is this...

Why is the universe flat?
Cosmic inflation is a theory that was proposed in the 1980s by cosmologist Alan Guth to answer some of the most fundamental questions of the origins of our universe. It also solved the Horizon Problem and the Flatness Problem.

Multiverse Theory Explained: Does the Multiverse Really Exist? Truth of Multiple Realities
Multiverse theory suggests that our universe, which consists of billions and billions of planets, stars and galaxies and extends out tens of billions of light-years, may not be the only universe that exists. There could be another...

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!
