look at it this way, .....if time travel was possible, dont you think people from the future would come popping in randomly right now? Time is an incomprehensible thing. Time is not an object, it is not a theory, it has no beginning, no end, time is the representation of change. Change in age, change in appearance, but mostly change in age. There is no connection between time and science that can allow us to bend it to our wim.
I thought science said you could relatively slow ageing / perception of time by going near the speed of light or if space was very bent e.g. black hole stuff. Relative to non-near the speed of light existence you would age more slowly, and in effect travel forward in time.
I think if it was possible people would not go back only forward in time.
get the next lotto numbers and win a billion dollars sound a like a plan to me.
Now I don't know how to get my time machine to 85 miles per hour since you are only allowed to drive 81 miles per hour on the danish highway.
