This is supposed to show what you would see and the ecological impact on the Earth if a star exploded 25 light years away. Essentially, the increased cosmic rays would destroy the ozone layer and ultimately cause a mini-ice age that would render the surface uninhabitable for centuries. I can't gauge how accurate the information is, but it seems plausible.

I doubt God would nuke the galactic neighborhood just to reset humanity again, it's always been more targeted in the past. ;)
ReplyDeleteDefine "near". At some ranges the neutrino flux would make you evaporate by themselves. Neutrinos.

DeleteWaay too close for comfort.
DeleteI don't worry too much about supernovae and such things. Why? Because nothing can travel faster than the speed of light. In other words, if the object is 25 light years away it takes any energy from it 25 years to get here. The only problem is there is no warning since we won't see anything until the light and or energy arrives here. That said, space is exceedingly empty and there aren't a whole lot of neighboring objects to be concerned about. The nearest galaxy to us is 2.3 million light years distant.
