How Vacuum Decay Would Destroy The Universe
The universe is going to end. But of all the possible ends of the universe vacuum decay would have to be the most thorough - because it could totally rewrite the laws of physics. Today I hope to help you understand exactly how terrified...

TED-Ed: Whoever builds something here will be rich beyond measure | Fabio Pacucci
Since the 1950s, governments, companies, and researchers have been planting flags among the stars. But while it might seem like there's plenty of room in space, some pieces of celestial real estate are more valuable than others. As far...

Concept 7 - Stability and Change
Paul Andersen explains how stability and change are regulated in systems through controls and feedback. Controls are used to regulate matter and energy flowing into a system. Feedback mechanisms within the system are used to regulate...

Why is the Earth Round and the Milky Way Flat?
Our universe is not a very diverse place when it comes to shapes. Large celestial bodies become spheres, galaxies become discs, and there is little room for variation. Why is this? Well it turns out physics has some pretty strict rules...

Why Do We Get the Spins When We’re Drunk?
If you're old enough to drink, you may have had a few too many cocktails and suddenly everything is spinning. Strange as it might seem, that’s not because the alcohol you drank is messing with your brain! So what causes the spins?
