Since time may go on into the fute forever, we don't know I have been wondering about time travel. Since time had a starting point maybe it has an ending point or an expanding point and we are on it. We are in the future! Think about it.
If we are those on the very front end of the expanding progresing time, we will never be able to go back in time till we get to the point that we discover it. But since we are not advanced enough we will have to wait till some future generation discovers how to do it. But even if we had the ability right now, we would not be able to sice we are on the edge of time as it expands. It is like we are on the crest of a "time wave." There is nothing in front of us till we get there.
I think my "time wave" theory explains why there are no future time travelers coming back to visit us.
I would be interested in what some of the more scientific minds on this site like jtupper, Flagpole and Jim Fiore think of my theory. I would like to be able to test it if it can be tested.
