Now, I’m not going to say that supernovae are completely bad or good. We would literally not be here if massive stars across the universe didn’t periodically explode violently in the past. That’s the only way to create heavy elements and get them out for us to use in our blood or build houses out of or start life.
What I am saying is that if you are around a supernova, it will not be good. The gamma ray bursts alone are disastrous, followed by the expelled matter travel roughly one-tenth the speed of light. Imagine that you are driving 80 MPH on the highway, and all of the other cars are going 1.5 inches per hour, and that’s what it would feel like.
They are pretty cool though, and this summer I may be studying them and their use to determine the expansion history, present, and future of the universe. Yay science!
