Hi !
I'm trying to understand the Dark matter problem, because it scares me if clever people tell me they don't know out of what 23% of the universum is consisting.
But let's start with a simple question on GR:
GR is stating that a body moving at a speed close to c holds an almost infinite energy.
For explaining this Einstein introduced the relativistic mass which becomes infinite at c.
But if mass produces gravitation by curving the space time continuum, wouldn't this mean that because of this increasing mass/gravitation at a point BEFORE c already the body would collapse and become a black hole at a pretty high speed ?
Even a very small mass (for a example a proton) flying close to c would then become a micro black hole invisible to the universum = Dark matter ?
Probably for such a small particel we would need quantum physics and not GR, but
if our understanding of black holes would still apply to such a micro black hole, wouldn't this mean that there would be Hawking radiation until it slows down and reappears when the velocity energy is eaten up after quite some time ?
This leads to the next question: If the big bang really was a kind of explosion, wouldn't this suggest that the outer most masses had the maximum possible speed ?
If these particles would then hold almost infinite energy at almost c, wouldn't they instantly become such micro black holes and stay at the forefront of the expansion of the universum, until their energy eats up and they re-appear after quite some time ? And couldn't this then be what we call Dark matter (because of the black hole effect beeing invisible) and continuously emmitting background radiation and continuously produce reappearing matter (=universum still giving birth) ?
And finally couldn't this mean that the acutal Dark matter of 23% is a very small portion of the original mass of the universum simply at very high speed - so in reality we are not missing that much because it is really more a kind of Dark Energy ?
Please enlight me ?
