We are familiar with the three dimensions of {length, width, height},
but there is a fourth dimension called time.
We are all time travellers because we are are doing time travel at the speed
of one second per second
into the future.
We are not aware that we are moving in the fourth dimension. We are aware when we walk that we are moving in the other three.
Time is as real as the other three, but we have trouble in that we are constantly moving forward along this dimension.
Is it possible to alter our rate of travel along the fourth dimension?

For discussions on the nature of time travel there is a TIME TRAVEL FORUM.
