What If the Galactic Habitable Zone LIMITS Intelligent Life?

12th - Higher Ed
Our solar system is a tiny bubble of habitability suspended in a vast universe that mostly wants to kill us. In fact, a good fraction of our own galaxy turns out to be utterly uninhabitable, even for sun—like stellar systems. Is this why...

High Mass Stars

12th - Higher Ed
Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge...
