What Causes a Gamma Ray Burst? Hypernova vs Supernova

A gamma ray burst usually occurs when a very large star collapses into a black hole. This results in Hypernova, which is 100x more powerful than a supernova. It is relatively rare, but since there are so many stars in the universe, a few hundred thousand occur somewhere in the universe every year. Every gamma ray burst we have detected has been outside of our own galaxy. If it occurred within our galaxy, pointed directly at us, we would probably be fried!

Also, there is the on-going discussion about whether or not most of the element gold comes from hypernovae explosions. Because our planet itself contains way more gold than what can be explained by neutron star collisions alone.

Thats crazy to think about. Like a thousand a day. This is difficult to comprehend. Personally, its why I think we see expansion accelerating.

Hi Arvin, your video are so educational ❤.gratitude. I think you made a mistake in pronuncing 200 galaxies in universes!! Or it should be called cosmos ? What’s the difference Between cosmos vs universe??

They don’t have infinite reach. The inverse square law states that eventually their power will be so diluted over the cone of the beam that it will lose all properties of a cohesive beam
