I watched a video on nova about the "death star" and how the galaxies in the universe are loaded with these and when they blow up they are suppose to get rid of all life form of our physical nature I forgot the distance in light years but they are suppose be billions and billions of times more radiant than a star like ours. Probably stars like our sun enjoy it or what ever different type of life forms like our sun do.
Now to us, our life form we would say if something like that were to happen to our own planet,,we would conceptualize and feel,, that is so so bad all that physical carbon life forms just blown away oh how sad. But maybe to the earth it was like a nice refreshing shower of great radiance.(concepts).
any way here a link about it:http://www.pbs.org/wgbh/nova/gamma/
