Time Travel (1982)

The 1982 book Fact or Fantasy? (World of Tomorrow) by Neil Ardley features this picture of "time tourists" choosing their destination.

Time tourists choose an era of the past to explore. They then enter the time machine on the left and watch history unfold before them. But they can only view the past and not enter it and live there. The time machine does not show the future, otherwise people could change what is going to happen.

This is really incredible! How can we see the past if it already happened long, long time ago?
