This is just a theory from a guy who is not in anyway a genius.... "hawking radiation" is another word given to the infamous dark matter that resides in space. in the matter of what happens when a black hole consumes everything around it and spits out nothing in return results in defying the firm basic fundamentals of physics. when a black hole absorbs all matter including light it then transforms this matter into matter unable to the seeing eye as it is on a completely different spectrum unknown to us as of yet to be detectable by any human instrument; such as infrared, electromagnetism, gravity, light, radiation
black holes are engines, they absorb space; that is what they are designed to do. but to what end? its simple, they absorb space but instead of just taking it all in and nothing happening it is redistributed but to what? another simple answer again, it is transformed into time; space's counter-partner. one without the other would have no true existence. it would stop us from evolving, from learning, from being self-aware human beings.
dark matter is the result of a very simple engine (black holes) which in part changes the basic physics that we see and feel today. dark matter is undetectable yes this is true but it does not mean it isn't there. it is what fills the gaps of our universe. dark matter is unaffected by trivial things such as infrared, electromagnetism, gravity, light, radiation. it does not emit light nor does it take any 3-D physical shape and by that i mean, it is without means to be able to touch it or even see it. the universe is expanding and increasing in size. it is because of dark matter that it does this. with all of the energy that is consumed and then redispersed from a blackhole is what creates this.
Now extending my theory on to a greater length... space and time are they one of the same? space is of course devised by length, width and depth which creates our 3 dimensional world and universe we see through our telescopes. but what of the 4th dimension time? time is the very thing that we cannot see; for example when we look at a picture of some scenery, we see the mountains, the sun setting in the distance so we can visualize for ourselves what it looks like but for time all we can do for that is wait and watch it. time is i think connected with dark matter. it is what makes things change the way they do. for what is a rock to do if there is no time? it would be like it was a photograph unable to move or change. time allows action to be taken; lets say a father and son will walk along a lake and the boy will pick up a pebble and attempt to skip it into the water. those actions can not be taken unless there is time. dark matter is spewing all around the universe from an unimaginable amount of engines (blackholes) and there is a law to it as well as I am no mathematician or any genius. but i can say that the universe expands because the laws of physics dictate that there can only be a certain amount of dark matter to influence time and matter to which fills space.
Next another interesting thought is of the time traveling theory. people think of it to travel to the past or the future but the only thing logically possible would be to slow time. to manipulate space and time. tear down the barrier that blocks time from existing in the 3-d world we know. But what if we ourselves went the other way around; instead of trying to do that, try instead to cast ourselves into the realm of the 4th dimension (time) traveling to the past is not possible; it simply isn't. as for the future, you would be able to go there but you would have no means of returning to the present. wherever you go, you are stuck there unless of course you decide to travel even further forward.
Then theres the tricky part of why gravity affects time. the more mass the slower you go right? well, i think with more gravity comes less dark matter concentrations. when there is more space around you, time moves slower. i'll say again, i'm no genius but it seems to make sense.
