Today after watching a show called "Parallel Universe" and they talked about Parallel Universes of course. But the interesting thing is that they said that gravity is weak. For example. Like how the whole earth pulls on you and yet you are able to pick things up in a heartbeat with no problem at all. So they later come to the conclusion that gravity is leaking from our universe into an 11th deminsion. This is called M-Theory. Later they say that what if gravity wasn't leaking from our universe but to it. What if it came from that other universe inwhich the gravity would be as strong as the other forces but by the time it reached us it would only be a faint signal. So my question is how likely is this scenerio.
