This isn't anything new really, Pulstars have been a common word to describe dead stars that spin. You can learn more about them on Cosmos!
Cosmos ROCKS!!! Carl Sagan ROCKS!!
Pulsars are cool as hell. Black Holes absolutely intrigue me though.
It's amazing that Einstein actually theorized black holes, but dismissed himself because he didn't think god would create such a destructive force. But in the end they do exist and we can thank them for us living in the universe we do.
I guess eventually all the universe will be is a bunch of black holes drifting through empty space. But I guess then wouldn't they eat each other up and then eventually the only thing left in the universe will be a super giant black hole?
...I just blew my own mind. lol
