# Is it possible to mould _ruptures_ in Space-time?

In one of the documentaries hosted by Morgan Freeman, a reference was made that just like an ordinary three-dimensional object like a ruler has scratches and cracks, in the same way there might be minuscule loops in space-time. My question is this: If many bodies of extremely high densities are brought close together, will it deform the space-time fabric and hence create a permanent loop in space-time that might be accessible if ever achieved?

Are you asking about making a wormhole? See en.wikipedia.org/wiki/Wormhole for what a wormhole is. – John Rennie May 22 '12 at 18:03
What is a "rupture" in space time? The concept doesn't make sense to me. – Ron Maimon May 23 '12 at 6:08
Not exactly a wormhole, because that would imply that we are trying to enlarge an already existing rupture in space and time, whereas what I am referring to is creating a rupture only in time. However, an unintentional space rupture is possible if the objects of very superior densities are brought together. – Graviton May 23 '12 at 16:51
A rupture means a warp. I'm sure that you're familiar with the idea of a very massive object "warping" the space around it. When I say 'rupture', I mean that space-time is caused to distend to such an extent that it no longer exists in that portion. I would like to use the bed-cloth metaphor. If really sharp/heavy objects are placed on the cloth, it tends to tear, hence making a gap in the middle of its material which allows free transport between the two sides of the cloth. The same way, ruptured space-time should be able to provide this free gap between any two accessible ends. – Graviton May 23 '12 at 16:58
@argentocyanide: Space is not like a rubber sheet--- this is a bad analogy. You mean a jump point--- a surface where you jump as you cross somewhere else--- but this type of gluing is not distinguishable from nothing except to the extent that the effective 4d space is full of curvature. – Ron Maimon May 23 '12 at 20:05
