Could Dark Matter be parallel Universes?
« on: 02/05/2013 05:30:01 »
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,

What do you think?

I would have to say no because the term universe is typically used to refer to everything that not only exits in out universe but also acts in our universe. Objects from other universes simply can't interact with objects in our universe. Just think to yourself what the term universe means to you.

The astronomy textbook The Cosmic Perspective - Second Edition defines the term as follows. From the glossary of terms
Quote
universe - The sum total of all matter and energy.

What is this categorical denial of possibilities? There are actually theories about gravity being the weakest force simply because it can pass between universes, which dilutes it.

I believe you're talking about the multi-verse or as some refer to it: "The Bulk"

Yes, but that theory leaves the possibility open that gravity from one universe can affect another.
