You and the professor have driven your DeLorean back to the past to fix issues with the spacetime continuum caused by your time traveling. But another DeLorean appears with older versions of you and the professor. The professors panic and explain that the universe could collapse now that you’re both in the same time and place. Can you merge the timestreams and travel home? Dan Finkel shows how.

The unfortunate thing, is if you had time travellers go back to the past to do the same thing you did, that means paracausally whatever you did was not enough to stop Riff from becoming a tyrannical ruler, since if you did stop it, it would have been not a problem that they would have needed to solve.

I'll be honest; I couldn't help but give myself a high-five to see what would happen. Would I have/Will I both time explode, would I time merge, or would everything else time explode or would time itself collapse? I would need to know. So I doubt I would have noticed the professor poof away or that the timeline needed to be fixed. Sorry everybody but good news, you are reading this so I never get the chance to time travel.

@jerryhook5906 Год назад

No, nothing like that. Your cells are constantly being replaced with new cells, especially when it comes to skin. So the skin cells on your older self's hand are not the same skin cells on your younger self's hand. You'd just have matching DNA. That's all. Hardly any different than giving a high-five to your twin.

@RidireOiche Год назад

@@jiwon.p It's unclear why this is even a problem; if the older one is around, they can just tell the younger one the answer. As for the fact that no one has ever seen a time traveller before and lived, perhaps the timetravellers are made to dress for the era they are going too before leaving and use cloaking technology to remain unseen, making time travel is more of an attraction for tourists. People who claim to see ghosts or aliens may be catching hiccups or technical difficulties with the invisibility technology, like spiderman. Or the timegate theory thing, if a time gate is built the earliest point in time that can possibly be travelled back to using the time gate is the moment it was finished making it impossible to have time travellers before the timegate is built.

@sorsocksfake 17 дней назад

One's at the exact north pole. 1 mile south of it you turn east, but no matter how far you drive there, it'll still be 1 mile north to the north pole. The second is just above the south pole, where driving east will send you into a circle; it should be placed where that circle would be 1 mile. Roughly this would be at 1 mile /2pi, or about 0.16 miles north of the south pole (the direction doesn't matter, just pick the part with the best surface); you start 1 mile north from there. Possible problems: - you must make sure the surface is navigable. Particularly on the north pole, it has to be well frozen to support the car, aside from all issues of snow, ice etc. - at the south pole we get a second problem. Here we must drive a full circle with a length of 1 mile, and a radius of .16 miles, or about 280 yards. If we're also supposed to get a certain speed with that (88 mph), given the ice and all that, this might pose some difficulty. Bear in mind, in both cases the journey east is not in a straight line. You need to constantly steer on the same circle. So it most likely will require preparing a proper road. Finally, we'll also need to stock up on some weaponry and money... getting to both poles for a rather insane mission may require both.
