More Universes
Is it possible, or ever been postulated and discounted, that what is driving
the acceleration of our universe's outward spread, is not energy contained within, but the gravitational pull of many other universes? Bill C. |

It doesn't work. If the "other universes" were located in a spherically symmetric shell around ours (and they would have to be to maintain homogeneity and isotropy) then their net gravitational influence would be zero. The gravitational force due to a spherical shell of matter is zero for a body inside the shell. |

The gravitational force due to a spherical shell of matter is zero for a body inside the shell. O.K. I think it's the part in the (parenthesis) that I was unsure about, that is that the increase in acceleration is occuring more or less uniformly in all directions, which makes the whole idea pretty hard to fathom if external bodies were to blame. If the theoretical universes were relatively close (say an object at the margin is closer to the next nearest universe than to its own universe's center) would the force of a spherical shell of universes still be zero for that body? Looks like the answer is yes. Thanks for the feedback Greg. Bill C. |

Hi Bill C I posted a theory that the universe has both concave
space,and convex space,and I'm using Einstein's space geometry.(He might like That) Convex space taking over say 11 billionLY away. We live in an area of concave space(inward) Inward comes from within the micro realm,and it carries this gravity effect for 11 billion LY out.Nature balances gravity force by convexing space to the next 11 LY,and this is why if you read my posts the BB took place 22 LY ago. Well that fits with my thinking. To sum it up gravity can both attract(as we see it) or repels large structures 11 billion light years away from us with an accelerating speed,that gets closer and closer to "C" Bert |

The gravitational force due to a spherical shell of matter is zero for a body inside the shell. Just to be speculative, I've wondered about the universe rotating about a 4th dimensional axis. I think that would produce an accelerating expansion in our three dimensions. Strange phenomenon though, that accelerating expansion. It's like the rest of the universe took a good look at Earth and said, "Lets get the heck away from those guys!" (:-)) -- Regards Fred Remove FFFf to reply, please |

Hi Fred I helped answer this question in today's "What if" post. I
feel it all comes out of the escape velocity of the BB. Bert |
