Hi all,
Alright so while reading through some stuff, I came across something peciluar, string/M-theory state that rips in spacetime are a natural phenomenon and happen all the time. "Edward Witten showed that strings, which have spatial extant, can travel while encircling the tear as it takes place. This, in effect, cancels out the potentially disastrous consequences of an actual rip in space. This conclusion relies on the fact that the two-dimensional worldsheet a string "sweeps out" as it moves essentially shields the rest of the universe from the potential effects. Moreover, there is always a string available to provide the shield - according to Feynman's sum-over-paths method of quantum mechanics calculations, all objects travel from one place to another by traveling along all possible trajectories. This ensures that a infinite number of strings will be passing by the tear when it occurs, thus protecting the universe from the effects of the singularity."
Now as crazy as that sounds I want to find a way to remove this shield, hypothetically this should cause a cosmic catastrophe but let's not worry about that at the moment :) so how can one go about doing that? Possibly with a lot of energy but strings themselves are made of energy so how does that work out? Also another request, can anyone point me to the paper where Ed. Witten shows this concept? Thanks a lot :)
