"The future ain't what it used to be."



To all of you who say, "Time travel is impossible, period.", wormholes are the most likely of choices to travel to another time and place.
If the collapsing wormhole was filled with negative matter, it would cause the worhole to stay open long enough for a spacecraft to travel through. This is like cancelling out the feedback whine on an amplifier.
The only problem is finding the wormhole and discovering where it leads. But, I believe there are wormholes everywhere, leading to every time and place in the universe.
