Hypercube Posted July 15, 2007 Share Posted July 15, 2007 I was just thinking. If a black hole were in a universe that contained as much exotic matter (matter with a negative mass) and negative energy as our universe has in normal matter and energy; wouldn't the black hole technically be a white hole in that universe? Since exotic matter and negative energy are repelled by gravity as opposed to attracted by it, the black hole/white hole would repel everything in that universe just as much as a black hole in our universe attracts matter.

Surely it'd look the same as a star with the event horizen being the point from which no light could pass being the brightest point of the star, fading outwards... but from far enough away it'd look like a point source...
