Previous future: a fable and hypothetical

A silly fable I “discovered”:

Maurice Rexham was a professor of mathematics at Wichita State University, and one of most skilled mathematicians in the country. He was also a very devout Baptist, as one might be wont to find in Kansas. Thus, one particular evening as he was putting away some towels and linens, standing near the open door to the bedroom where his daughter and her friend from school were studying (or whatevar), he overheard a song playing. In a strange man’s strained voice,
Heaven,
Heaven is a place,
A place where nothing,
Nothing ever happens

Naturally, to a deeply religious man, making such statements about God’s glorious domain was outrageous. Heresy. Blasphemy, even. Maurice was upset and troubled at hearing this, and it ate at him for several days, until at last he decided to bolster his own faith by proving that it could not possibly be true. With his thorough understanding of the principles of physics, solid grounding in philosophy, and inestimable mathematical skills, surely he could construct an irrefutable proof that there could be no place in time, space or beyond devoid of events.

For fifteen long years, the professor labored in his spare time to craft his thesis, striving to be comprehensive and inerrant. It had to be flawless and unassailable. When they found him, pencil in hand, head lying on his desk, expired from an unexpected massive stroke, the page his cheek was pressed to described part of an ancillary lemma to his masterwork.

Rexham’s Theory, even not quite finalized, was indeed impressive. More importantly, the key principles that underlay it led to some significant discoveries. His detailed analysis of temporal dynamics came to be used to contrive and develop a ridiculously simple, efficient and powerful world line reshaping device that allows our space-faring vehicles to cross immense distances very quickly at mundane rates of speed.

In a way, one might say that God himself has given us the stars. We can tool on over to WR136 (or what might be left of it) and back in about a month’s time, traveling and returning in a coherent frame of reference. And the Theory’s body of work has allowed us to establish a useful and consistent means of measuring these great distances that are rife with relativistic distortions: a benchmark known as the “moresex” (about 12 lightyears), in homage to the professor himself.

Science is, of course, full of impishness. The WSU Engineering College twisted Maurice Rexham’s work to build a device that was able to bend world lines completely back around. They constructed the long sought after Time Machine that would allow a person to travel backward in time. And it worked beautifully, apart from two tiny limitations.

The first limitation lay in the fact that the machine would only transport the traveller backward in time. No matter how hard they tried, they could not build a conduit to the future; we are stuck moving forward at the normal pace. The second limitation can be much more serious: the time traveller must not, ever, be in danger of a coincidence paradox. One may only go back to a time prior to one’s own existence, and if by residing in the past, one runs up into their own timeline, all of that traveller’s existence will vanish from all of ever.

The hypothetical for you is: how old would you have to be to use one of these devices to venture into the past, never to be in this now again? And how far back do you think you would want to go?

This problem requires the reader to make one very large determination:

  1. How long will I live in current time?
    AND
  2. How long/much longer would I live in the chosen (past) time?

And: p.s. - can I also choose to change PLACE as I retrogress in time? If I am stuck in the same place (say, a desert) when I go back, I am NOT going to choose a time prior to air conditioning.

Not to mention: nothing of any conceivable interest has happened here until the 18th century, and even that was boring. If I could change time AND place, I might be interested.
Now to hear from all the people who would have died in infancy had they been born before 1950.
And all the ones who can’t even start a fire, but want to go back 500 years.

Let us assume that the device has a transport function (since it goes though spacetime). Further, let us posit that it has a vehicle-like property, rather that a fixture-like property: to use it, you take it with you and may proceed backward over and over, if you like/need.

I’m having a hard time coming up with any reason to travel into the past at all under these circumstances. What age to do it at seems totally irrelevant. Might as well ask me what color socks I’d like to be wearing when the next solar eclipse happens. :slight_smile:

The only reason that would motivate me to go back into time is intellectual curiosity. Watch the Big Bang. See a dinosaur. Save the Library of Alexandria. Things like that. (And let’s be honest, only one of those is remotely possible for me to achieve, and it would probably eat me right after I saw it.)

As for the age, the only time I’d travel is a point at which I have no commitments left to modern friends and family. Perhaps after my wife dies, but that’s not something I can put an age on. It would surely be a suicide trip because there’s no point in history when I could be as safe, successful or healthy.

Yeah, that is my point about age. You would have to be old enough to have nothing compelling you to stay in the present, I would think. I mean, I would consider it at some point, just to experience something rather different.

I dunno if I’d actually do it or not, but I’d like to be among the first to at least fake it so that I could help establish the new ritual of giving your own eulogy at your memorial service before leaving.

The social and cultural implications are fascinating.
