G'day!
This is not exactly a new theory. It was theorized after observation of one of the galaxies in Virgo several years ago revealed what could be a supermassive black hole at its center.
A black hole at the center of a galaxy would certainly cause the galaxy to eventually spin (conservation of momentum), though interacting galaxies would work somewhat differently (many-body problems best left to the real physicists).
It's been said (proven?) that tidal motion does directly affect the human body. I wonder what happens if you try to extend that to the tidal motions caused by local black holes (less than 25 light years distant)...they would be strong enough...
Also, there are Hubble pictures of black holes firing out continual super-jets of gamma rays and other extremely high-energy particles from their centers/event horizons. What of the effect on local space from these jet streams?
Oog. My brain already hurts.
And I have no idea about a real answer to your question, on account of we would have to know for sure what's outside of the universe we currently inhabit. What's the emptiness our universe is founded on? Is it something smaller than the Planck limit (<1.0e-36 cm)? You wouldn't be subject to gravity at that size, but space would be very empty as well.
Hey, is it just me, or does it appear that the smaller you go into things, the more they begin to resemble the extremely large things? |
