I wasn't talking about wormholes already existing if that's what you're referring to. I meant, developing the technology to control and direct them.
I am not making an assumption about time travel. The government HAS the technology, it's just secret and not all around known.. Which is why I refuse to argue about it here, because the evidence is little, though it is there supporting the notion, you just need to search. It's not well known information and is kept out of the hands of most science not directly involved in government activities. Even if they did have it, we can't force them to give it up, so it doesn't matter if its true or not.
But then all that ties into conspiracy theories and such, which is why I won't go into the existence of possible time travel devices in this day and age.
Time travel IS mathematically possible in theory. Theirs multiple methods. Worm Hole transport(which for now hasn't actually be done to public scientist knowledge, but theorized based on the actual nature of worm holes. There's reaching a speed higher than light speed, this would cause one to travel backwards in time, though nothing with matter not already going light speed can reach light speed (or as far as we currently know). Einstein said nothing about entities or objects already traveling at light speed.
There's other theoretically methods mathematically proven, their just not available to my conscious thought at the moment, I may remember them later.
There's also the all the Quantum Physics 'stuff', which I only know a tiny bit about. The concept of Time-Space where Time is 3D and Space is Linear/1D, its what allows worm holes to connect to alternate universe and alternate places in time. (and no this is not sci-fi, I do not watch sci-fi movies, it may be in sci-fi, but it is also existent.)
