Mathematical model of a 'TARDIS' takes the 'fiction' out of science fiction

Summary:

After some serious number crunching, a researcher says that he has come up with a mathematical model for a viable time machine: a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He describes it as a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time.

As long as there aren't any daliks.

Tippett says. "While is it mathematically feasible, it is not yet possible to build a space-time machine because we need materials--which we call exotic matter--to bend space-time in these impossible ways, but they have yet to be discovered."

They will be discovered in 2021.

I know this because I just returned from 2022.

:D

And he only wants $100 billion to build a prototype.

No, it’s not possible. No matter how many equations they write, there will be no time travel.

Why?
God is the only being that is outside the continuum of cause/effect. Humans are stuck in that continuum and have no way to get out.

Cool. Any stocks that you can recommend?

[camle]

so unless space/time is curved you can’t steer? i call baloney.

[Seaplaner]

Cool. Any stocks that you can recommend?

I promised not to, as it would be unethical.

Hmmm, I wonder if that includes sports betting...

If only I could go back in time and tell my younger self to never, ever sell my ‘95 Mazda RX-7. The most fun car I ever had. Would also need to keep my mom from throwing out all of those baseball cards. Should also warn myself about one ex-gf before things got too serious. Actually, there’s quite a list.

Yes he is a quack. But we can affect what apparantly happened in the past in regard to wave function collapse per our choice to observe it. Our bodies are part of the natiral universe and operate in its space time, but we are hybrid creaters with a faculty for reason and moral apprehension and free will in eternity.

[dhs12345]

No, it doesn’t because I say so. Which team is going to win the Super Bowl?

[Safetgiver]

If you did all that you’d realize you have (HAD) never really lived life at all. Life living is honey as well as shiite. Remember the poem about Richard Corey?

[SkyDancer]

The past is done; we are the future of the past. The future to us hasn’t happened yet. Today is the tomorrow we worried about yeste3rday.

[dhs12345]

But the timeline where you had kept the RX-7, you would have died in a crash. Consider yourself lucky!

And you girlfriend — you probably learned a valuable lesson — what doesn't kill you makes you stronger. :)

[bigbob]

If Stephen Kings version of time travel is right, the past resists being changed. So the RX7 would likely have gone and the GF stayed anyhow...

[fella]

I think we all have a list like that.

[Windflier]

You first have to accept that time is anything more than an apparency, to entertain the idea of time travel.

[BenLurkin]

The good news is he can tell you.

The bad news is that by placing your bet you will alter the future.

[Windflier]

If only I could go back in time and tell my younger self...

Maybe for the better? Then again, maybe not. The important point is that I have to be careful to not draw attention to myself and the space aliens who are maintaining the fabric of space-time.

So a few small, well placed bets. And not too many times since I will draw attention.

[BenLurkin]

Smart.

Too big a bet and it wouldn’t be the aliens you’d have to worry about. It would be the mob.
