Could Dark Matter be parallel Universes?
« on: 08/04/2013 20:30:04 »
RF  asked the Naked Scientists:
   
Dark matter is inferred because the strength of gravitational tugs is stronger than can be accounted for by the amount of observed matter in our universe.

Could these "tugs" be a consequence of other universes interacting with ours rather than the mysterious dark matter? I recently read that gravity was one effect which might leak between universes.  

Thank you for considering my question,

Ron Fussell, Vancouver, British Columbia

What do you think?

That is one of the hypothesizes floating around these days coming in on the heals of M theory. Ask 50 people to describe Dark matter and you'll probably get 50 different answers. I haven't decided yet which one I like the best, just too many unanswered questions to make that leap. Maybe the LHC will supply a few hints as time goes by?

A couple of thoughts occur here.

1. Why replace "mysterious dark matter" with an equally mysterious interaction with another universe that may not exist?

2. When I read about gravity being weaker because it might leak into other universes I wonder why it would not leak the other way as well; unless one makes the (unwarranted?) assumption that gravity is weaker in other universes.  I also have a bit of trouble imagining the mechanism of leakage.
