Physical phenomena are supposed to require an arena in which they may occur. That stadium is spacetime. But in the quantum realm is there such an arena — that is to say, does the stadium exist before the game begins? Or does it emerge as we observe it? Can we change spacetime? May we alter the past without time travel?

It is by now generally accepted that, in the quantum realm entities — minuscule particles — somehow come into existence at the instant that they are observed. In the study of quantum topology there may be different scales at which explorations may be conducted, ranging from the very small to the entire universe.

According to the laws of quantum mechanics a basic assumption is made: an assumption of a pre-existing structure. At the very small scale all attempts to observe that assumed structure inevitably change the topology itself; the large amount of energy which has to be applied distorts the arena's very structure.
The topic of quantum topology has thus far spawned two projects.
