Journey Into The Future

Space and time are interwoven. We cannot look out into space without looking back into time. Light travels very fast. But space is very empty and the stars are far apart. We can travel fast into space only by travelling fast into the future. But what of the past? Could we return to the past and change it? Could we make events turn out differently from what the history books tell us? We travel slowly into the future all the time, at the rate of one day every day. With spaceflight we could travel fast into the future. But many physicists believe that a voyage into the past is not possible. Even if you had a device that could travel backwards in time, you would be unable to do anything that would make any difference. If you journeyed into the past and prevented your parents from meeting, then you would never have been born. Which is something of a contradiction, since you clearly exist.

Perhaps time itself has many potential dimensions, despite the fact that we appear to be condemned to experience only one of them.

The mind boggles at what could happen if one could go back in the past and change it. If that kind of time travel were possible, then every imaginable alternative history might in some sense really exist.

“Bringing back the past” is but one conundrum that the concept of time and space brings to mind. There are countless others of course that would fill many a fascinating page.

But perhaps we should take things one step at a time. Let’s ask God what he thinks.
