I watched the Prophets of Science Fiction on the Science Channel yesterday. The show focused mainly on H.G. Wells and Jules Verne. But there was an interesting segment on Dr. Ronald L. Mallett, an African American physicist. He's working on building a time machine.
He got the idea after readings Wells' The Time Machine; his father had died a few months earlier. The 10 year old Mallett imagined that a time machine would allow him to see his father again.
This article explains how the time machine would work far better than I ever could!
Imagine if such a machine did exist? We'd get our 40 acres and a mule! Well, not really. Mallett says, "You couldn't go back in time to a time before a time machine was built. 'So I don't think we can go back any further than when we have a time machine that works.'" Got that?!
Maybe one of these days....
