On the other hand what would be the down side if the black holes they create start bwhaving in a way they didnt expect them too? I sure wont like to
be here for that one.
Well.. There are some things you should probably know first before believing that black holes are going to destroy the earth. If the "Hawking
radiation" model is correct it means that large black holes slowly deteriorate or "evaporate" over time. This obviously means that a "micro black
hole" would probably only exist for an extremely short period of time (depending on its mass) before it simply disappears. Therefore, the length of
time a micro black hole exists is directly related to it's mass and density. Therefore, even the smallest black holes would probably only exist
within miniscule time scales (we're talking Planck time here). The only period of time we have been acurrately able to measure is the
"attosecond", which is 1,000,000,000,000,000,000,000,000,000 times the length of time we are talking about with regards to Planck time.
If micro black holes are possible (scientists believe they are) then it is possible there are black holes much more numerous on these smaller scales
while there are probably much fewer super-massive black holes in the universe. This could be the very explanation for dark energy and why we are
seeing the universe expanding in all directions.
Some scientists think that all black holes have a corresponding "white hole" which operates exactly opposite of a black hole since it expels matter
into the universe while a black hole takes it in. If so, this matter undergoes extreme conditions passing through the event horizon and so distorts
the quantum makeup of the universe that it could very well go back in time and be expelled in completely different parts of the universe. Possibly
even millions of years before the black hole that created the white hole even existed (which is pretty mind blowing in itself). This means that it
could be quite possible that these miniature white holes are popping into existence ALL over the universe and expelling small amounts of
atomic/subatomic matter. But this "matter being shot back in time" would depend on whether or not we can go back in time due to exceeding the speed
of light. We know that the laws of physics may not exactly be breakable, but they CAN be bent. The only question is to what degree this is
It may even be that the entire reason the big bang occurred is because of these white holes being compressed into a smaller and smaller universe
(since all black holes that could now be sending matter back to that time period would have a smaller and smaller area for the white hole to expel
that material. This is because the universe has been expanding since the big-bang which means that if you were ot go back in time the universe would
inevitably be smaller and smaller. Pretty simple).
Some scientists also believe that the connection between a black hole and it's corresponding white hole is a wormhole. And if so, then every black
hole would have an exit on the other side of it's own corresponding wormhole (this may be a little too star trek for some, but bear with me). If we
could ever control gravity to the degree where we could negate the crush of gravity (by creating negative gravity artifically) within a black hole, we
could simply pass through the event horizon and come out on the other side of th wormhole completely fine.
But there are all kinds of interesting dilemmas that are simply unanswerable when dealing with time travel as we all know.. The pool cue paradox is my
1-You shoot a pool cue into a small wormhole.
2-The pool cue travels through the wormhole towards the exit.
3-The pool cue exits the wormhole on the other side having traveled back in time to the exact moment it was about to enter the wormohole.
4-The pool cue hits the other pool cue traveling towards the entrance, thereby preventing it from entering the wormhole altogether.
What would happen? Would they both simply vanish? THESE are the kinds of things we have no idea about.. And the paradoxes only get more
Sorry for my rant, but these are the things I think about.. In 2004 I talked to my stepfather about my idea of how black holes might be able to
accelerate matter and energy not only to critical density at the event horizon, but possibly past the speed of light altogether sending it back in
time. However looking at a black hole's event horizon we would have no idea where this accelerated matter has gone because it would no longer exist
in this dimension or time-frame altogether. It would not be directly visible or, otherwise, directly observable.
Then last year I heard about this idea of white holes which, ironically, is extremely similar to the idea I had in 2004. But before last year I had
no knowledge of these white holes.. I guess sometimes we all think alike..
