A white hole- not a place where energy spews out, but rather something just like a black hole but with some sort of antigravity- what would it do? What I mean is, would its effect on time (since black holes warp time so that being near them slows down your time relative to a far-away observer) be REVERSING or INVERSE? If I was near one, would I go backwards in time or would my time be sped up relative to a far-away observer? (Yes, I know that no evidence suggests such things existing, I was simply wondering about the theoretical effects one would have) Also, should this be in the General Relativity forum instead? Sorry if I've posted in the wrong place!
