Seanchaidh Black holes are just dead stars that have collapsed in on themselves, creating an incredibly dense core of matter. This core has such a huge gravitational pull that all matter surrounding it within its "Event Horizon", including photons (light particles), are pulled into it. They cannot be seen, merely detected by the gravitational effect on surrounding major astronomical bodies. They are not portals to another time or place, they are just very small balls of immense mass. The idea of a portal through time and/or space comes from the wormhole: a theoretical bend, crease or ruffle in the fabric of the space-time continuum. If such a thing were to exist then, supposing we had the technology to get to it, it would allow us to primarily travel through "space". Because the distance we would be travelling would (possibly) be so immense, we could arguably be travelling faster than the speed of light and therefore also travelling through "time". We must remember that the light we see reaching us from these distant stars and galaxies and so on is sometimes millions of years old: it does not show us a current picture of the universe, but a picture of the universe as it was all those millions of years ago. We have no idea what a black hole leads to, its been proposed that micron black holes are all around us, how due they stop fro being giants? Planck mass says these would be smaller than a electron and therefor be evaporated before it gets anywhere also a new thing suggest that a electron may be a micro black hole

Seanchaidh Steven Hawkings Seanchaidh Wow, that was a conversation stopper! question The thread was pretty dead for about 11 days! Finals are near for most here.

"The funny thing about black holes is... ... ... well, lol, nevermind...
Have we ever found physical proof of black holes? We have all these speculations and guesses and mathmatics for these things, but have we ever actually gone out and found one? All the pictures I've seen are Artistic Views of such matters...
Yes, Hawkeye Radiation is something, but I've read somewhere that black holes are not the only things that create Hawkeye Radiation, some other things do such as Neuton Stars (I believe). So, what exactly is the validity of Black Holes existing?...
Instead, when a start collapses, maybe all that matter falls back down to the Basic atomic form and scatters throughout space like an explosion? Why does it have to become a black hole? Think of a collapsing building, the matter and the point of collapse spreads out in all directions, why do we just assume (if we do) that it all stays put and forms a black hole?...
Just a couple of questions that came to mind right now as I'm waiting to eat dinner and leave for my Manderine Chinese Classes"...

Black Holes are from the General Theory of Relativity. This means that this is one of the possible products of... Well, I dunno. I don't know much about black holes. But the second statement of this paragraph is applied generally to theories.
