If I Thought of a Way to Build a Time Machine

Before I ask, I want to let you know that I don't have a link or anything, just a general question.

If I figured out a way to build a time machine and started drawing out blueprints, gathering parts, etc., could I expect to get a visit from my future self in the time machine I invented? And if so, could I just use that one instead of continuing my current plans or would it disappear?

I would assume you would need to finish the machine to secure the chain of events. SO if anything expect a visit from your future self AFTER you have it down.

It all depends if its indica or sativa...

Have you got the time to build one?

But shouldn't I just need to start the plan of action? I'm not saying I wouldn't finish it over the course of time, but could I, right here and now, get a visit from my future self?

Lol, what does that mean?

a reply to: Thirty6BelowZero

If you was successful.

You could ask your machine to appear near you in x minutes.

If it doesn't appear.

You failed.

If (future) you visited (present) you in a time machine...a secondary timeline would exist.

For a time machine, I'd make the time. I would come back to visit my younger self if I did build one. That's why I'm wondering if I could expect a visit before I finish it in this current time. I have the dedication.

Multiverse theory: you'd never be greeted by your future time travelling self, you'd jump into a parallel dimension where you'd spontaneously appeared in the future/past. If there's infinite universes, your odds of future-you showing up here are slim.

The universe you visit's 'you' could meet you though.

I believe many timelines exist simultaneously.

Nice theory. I've never heard of it before. Do you believe the other common theory where you could visit your past self? I'd make my way through every century, could that happen in the multiverse theory?

A "time machine" is actually an FTL spaceship. Time is not a function of distance and speed, but a characteristic of space itself. It's the reason we call it spacetime.

Warping space is the key to interstellar space travel and it is the key to time travel, however, there is no mechanism to allow us, so far, to travel backward in time.

Causality (the 'c' in E=mc^2) would not be violated and I refer you to the Photon Clock for the reason why. This is a function of General Relativity. Space can expand faster than light, and currently is according to the Standard Model, it is also accelerating.

Revisions of Alcubierre's Warp Drive equations have significantly reduced the energy necessary to produce warp bubbles, but it is still a very large energy coefficient, one that the White-Juday experiment was unable to achieve, and therefore made the experiment inconclusive.

I would draw up the exact time and date in the plans for me to come back and visit.

Have you ever heard the theory that aliens are us from hundreds of years ahead? I've seen one in the late 80's follow me and my mom, who also saw it, over a treeline for about 200 yards and stop to hover over the treeline until we went inside our house. What if that was a descendant from several hundred years in the future that traced his/her family history and decided to take a trip to 198X to see a few minutes of what our life was like?

It depends on if paradoxes exist.

There are more than a few possibilities that have been talked about. One is there are infinite dimensions and traveling back would send you to one that you can change. There is another that says that paradoxes can't exist. Such as even if you could travel back in time you wouldn't be able to change the past in any meaningful way.

There are a whole lot of other ideas on the subject, but I doubt anyone knows for sure.

You could visit a past version of yourself, theoretically identical to your own past (except the part where older-you appeared suddenly and said "hi"...that fact differentiates the two universes).

Thank you. I'm about to leave for the day but I'll be back Monday to pick right back up here.

Maybe, once you invent a means to time travel and with your new understanding of time and quantum mechanics you realize meeting your NOW self would be detrimental to your personal timeline events and perhaps even world events. So dispite how much you promised your self that you'd come back to see yourself ... you dont.


That's why I always look around for myself hiding behind a tree or something. Cause if I couldn't keep the promise to my self and say hello to myself, I might still come back to this time and observe my self from a fair as keeping part of my promise to myself.

It has to be built by someone. You're suggesting that you would get a visit before you finished the work, before the machine was invented.

Have you ever noticed someone from a distance that looked just like you?
