Temporal Mining Theory

The Temporal Mining Theory is a theory that states if time travel were easily usable and available, an endless amount of non-renewable resources would be available for use, thereby essentially eliminating its scarcity.

The theory states if one goes into the future, mines an object, such as an asteroid, and then brings it back to the current time, the minerals acquired would still be there, if you had arrived at that same object a lengthy amount of time before you had originally landed on the asteroid, allowing you to repeatedly mine the same object, just by visiting it before you had already visited it.

There is no risk for a paradox because molecules exist in the time they exist in, and there is no evidence that something non-living would create one, especially if it is put into use and transformed into something else.

This creates the possibility of starting mining on an asteroid in a thousand years, and repeatedly going back a certain amount of time to mine the asteroid over and over for eternity. It is currently only a theory, however, and relies on being able to manipulate time travel.
