..think about it... technology is bounding forward, splitting atoms etc..so let's guess that in the next 100 years we'll suss out anti gravity, and maybe invisibility in 300 years.. and maybe time travel in a thousand years time...? But if they discover time travel, they can then go into the future and discover more technical ways or improving it... so it will be easy to travel back in time... and then mass produce it for everyone almost as a recreation... so take that 10,000 years hence, with population increases.. surely most people that live in the future will be visiting ancestors in the past ?
So where are they?
