Could be black holes source of a dark energy?
« on: 13/01/2016 01:09:13 »
Black holes consume a lot of matter and energy, but where does it go? 
Is it possible that a black hole generates somehow a dark energy and distributes it around itself?
If this is the case would we be able to detect faster space expansion around these black holes?

Welcome to the forum. :)

This answer is to say the least a bit obvious but where does it go? To the other side of the event horizon.
It makes the event horizon proportionately bigger and it also makes anything orbiting at a certain radius go around that little bit quicker.

Is it possible that a black hole generates somehow a dark energy and distributes it around itself?
If this is the case would we be able to detect faster space expansion around these black holes?
Our current understanding which stems from observational data, describes the exact opposite scenario to the one in your hypothesis. No Universal expansion at all can be measured within a gravitationally bound system. That translates to all the expansion happening where there is very little matter density.

The Voids between matter are getting bigger and they are getting bigger at an accelerating rate.

Thank you for your reply.
The hypothesis is just claiming that the dark energy might be produced by black holes.
It could be expelled from a black hole to a space that is around the black hole but also far away from a gravitation pull of any matter.
here is a short depiction of the thought:

Stephen Hawking seems to be stirring up the BH debate again.

If he is right and " black holes could be passageways to other universes", you could modify your idea to have expansion in our Universe being accelerated by dark energy coming from other universes.   

Have fun with that. :)

Nice bit of sketching.
For any serious consideration of such an idea on any level, you would have to describe a mechanism by which a Black hole generates all this excess spacetime, and also a mechanism by which this excess spacetime generated by a BH can then be transported to a void which by it's very nature is as far from the vicinity of any BHs as possible.
Maybe as Bill suggests, Hawking can come to the rescue and provide an other dimensional passage way that acts in exactly that manner. I don't know...
Good luck.

It seems as though he is still thinking in terms of a 2 dimensional holography. There isn't much detail at the link so no idea of the mathematics involved.
