is it possible to puncture a hole in the fabric of time and space?

Question

I don't mean have a large deep gapig hole such as a black hole I mean an actuall puncture and would gravity it self leak out and time it self eventually would it gradually slow down as it leaked out of the universe eventually coming to a complete stop?

Answer 1

spacetime and therefore gravity couldnt really 'leak out' because they're part and parcel of the fabric - its like saying if you punctured a basket would the wood leak out.

There are theoretical speculations that space could rip when wrapped in a brane without violating the laws of physics but this is tentative stuff with no experimental evidence - even in theory on the horizon. Incidentally some string theorists have suggested that gravity is weaker than all the other forces because it is leaking to another brane - a parallel universe as it were (but not like the ones you get from the many worlds interpretation of quatum mechanics!) but this isnt likely to be effected by a rip because it leaks out anyway. Where would the puncture lead to though? It kind of assumes there's something under space that we could get through to but there's nothing in physics that really suggests that possibility.

The only thing I've come across which might be similar is one end of universe theory known as the Big Rip (they're all 'big' big bang, big crunch, big splat) which involves an increase in the strength of dark energy - an increasing rate of expansion and spacetime tearing itself apart! We lack a sufficient model of cosmology and experimental data to tell us if this is really a plausible scenario. Interesting question though! Regards.

Answer 2

Brian Green (famous physicist) said that in M-Theory (theory of strings), tiny "tears" in space are possible but the stings move over this tiny rip in space acting as a protective sheild around it. And M-Theory already shows that gravity "leaks" our of our 4 dimensional brane into the other dimensions (11 total). So the only hole possible in the fabric of space is even tinier than the strings in M-Theory. To open this hole as wide as a penny would require a ridiculously large amount of energy, if it were even possible. And to get an idea of how tiny this is, if an atom were blown up the the size of our solar system, a string would be the size of a tree. The hole even smaller. So your answer is no.

Answer 3

Creating a black hole does create an actual puncture in space time. Everything on the other side of the event horizon is effectively removed from the universe. Time itself stops for items attempting to cross the event horizon.

Answer 4

You should study your physics better. The only way gravity leaks out is if mass leaks out. It would have nothing to do with time. Time has to do with relative velocity.
