Time Travel... what if?

[Steve]

I was watching a documentary about time travel, yes i did fall asleep but it;s interesting and I have always had a fascination on time travel.

The things I think about but cannot wrap my head round it properly.

1. Why do we always talk about the past as if it was behind us, when it could be in front of us? We always talk about our past relatives as descendants but on a family tree they are in front, above us. 

2. What if there is already time in front of us, a life being lived by someone else ahead. So material things like trees, grass, monuments, castles, rivers etc.etc. were left to us from the future, all this happened years before. 

Freaks me out lol

Funny.. just came across this video

Wow!  thats quite heavy

I remember watching a documentary on Einstein's theory on relativity and time & space travel

One of the only things i remember from it is that he timed a train journey and it clearly showed that time sped up but as soon as it stops then it reversed and therefore no advancement in time overall.

Concorde proved it through inter-continental travel at Mach2 but it always returned to the base setting

What would you change if you could go back in time, just one thing to change though

Mine would be investment, knowing what you know now (assuming you can take the learned memory back with you)
