I heard someone once say that time travel was not possible. If it was,why had we not been visited by people from the future. The reply I heard from a theorist of this genre was that for time travel to occur, a time machine had to be invented and turned on. Because we are not inundated with time tourists, he speculated, no such time machine has been invented yet.
I disagree. With today's back catalogue of images and sound we are awash with windows on the past. We can look back into our history like never before. Sure we cannot walk around in its three dimensional world but we can, when the fancy takes us, dip into it and view the kind of detail our ancestors could not imagine.
There are many things that we all remember from our teenage years. Favourite songs, favourite places, tastes and smells and of course images. There is probably one (or more) iconic images that we all remember from our youth. For me, mine will always be Buzz Aldrin standing on the moon.
Whats yours?
