In the centre of the universe I belive there is a giant black hole that all galaxies orbit
What are they "stretching from?" Can you please try to be a little more clear?Originally posted by Viper
Ok but what are they stretching from. If the universe becomes too stretshed will there be like an elastic affect?
The unviverse has no centre because it is not expanding from a single point like an explosion but rather every bit of space increases in size and then that it turn increases in size. The galaxies are not centred around a 'central area' (as far as we know).Originally posted by Viper
But then if you look at all of the galaxies they are swirled around a centre or central area or an object(s) of intebse gravity
As I recollect Hawkings work, the radiation is not from the center of the Black Hole, but from the interaction of the 'event horizon' with the 'fabric' of space/time.Originally posted by M. Gaspar
I don't buy Hawkings thought that because some energy radiates OUT that a black hole will eventually "evaporate". More stuff goes in; it becomes more massive; its gravity increases; it eats more stuff.
That is quite true for the Short ranging of gravities ability, but , Gravity is presently thought of as having Infinite range, till that is proven differently, we must accept, that given enough time Gravity will win out over everything else, and all will be drawn back together into a, well, whatever is the center of a Black Hole, presently thought of as a singularity.Originally posted by Brad_Ad23
And as was pointed out, black holes merely empty the space surrounding them.
