First, UV isn't between visible light and microwaves, in fact UV radiation has even shorter wavelength (bigger energy) than visible light. It's IR (heat) radiation which has longer wavelength than visible light.

Another thing about black holes I believe is that they change the wavelength of the light from an obejct as they go into it, so if you sent in a spaceship with a friend of yours in it, waving at the window, he and his ship would disappear in front of you before being torn apart, because the light sending his image to you would go from the visible light spectrum, to being stretched out to ultraviolet light and microwaves and such I believe...
So objects going into a black hole would literally disappear while going in, if you could watch them.
anyone wonder what is at the center of the universe???

Hey everyone, If blackholes do exist and they suck all matter and light inside them what happens to them? are they taken to another dimension or are they just crushed? if so surely the crushed mass must exist somewhere?

My bad on the light waves thing; however, I did read from somewhere that if a person was going into a blackhole, the effect of the gravity on the light carrying their image would either make them disappear in front of you, OR (maybe I got it mixed up), if they were recieving radio signals from you, even though you sent radio talk to them, they might never recieve the radio signal at a certain point because the gravity would stretch the light waves of the radio signal out too far. Something like that.
And I didn't say about finding the center of the universe, I just sugggested wondering what is at its center.
Sort of like what is at its edge (if it has an edge). After all, if the universe is open space expanding into nothing, and the universe contains matter, than what is at the edge of the expanding universe?? You can't crash into a wall, but you can't fly into even more open space, so what is there??
Some theorize there really isn't an edge, that if you started at one point of the universe and tried to go to the edge, you'd eventually end up back at the same place you started; think of it like walking around the Earth, but in more dimensions.

Actually fact that there isn't edge doesn't mean it has to be infinite.

if the universe is infinite you could never reach its edge. you would just keep going, on and on and on, and on. now the fact that its expanding- well things are just getting further apart in regards to each other, it doesnt mean it had a discernible edge to begin with, and that edge is getting further and further away.
The de Sitter universe solved Einstein's relativistic equations for an empty universe, so that gravitational forces were not important. It is interesting because it featured a system where measuring rods became shorter as the edge of the universe was approached. This allows the universe to be finite but to measure as infinite when inside, as the ruler keeps shrinking as you try to make the measurement! Another feature is that the shortest distance between two points is not the expected 'straight line'.

You know, all those odd socks that disappear somewhere between the laundry basket and the dryer. Things we are adamant we left on the shelf inside the front door only a couple of days ago that have now gone

yes, matter can b turned into energy, ever try burning a piece of wood?

The most likely theory to date goes as follows:
As matter falls into a black hole it adds to the mass of the singularity and creates a general "mush" of mass/energy.
Over time this mass/energy is put back into our own universe through gamma burst from the singularities poles and through hawking radiation.
Evenetually black holes evaporate (if they don't have a continuous suppply of fresh matter) through these methods of expelling mass/energy.
There is no direct evidence, but the gravity of a black hole might open wormholes (rips in space-time). However, this is more sci-fi than science for now.
