Time Travel

[johners12345]

Greetings Marines! Long time no see! Fuck introductions, lets talk about time travel and nerds from the average fucks!

Now, what is your opinion on it? Is it real, fake, explain your reasoning behind it!
if real, how so? Do you have evidence, do you believe you know the specifications of how it can be done? What theories of time travel do you believe?
(Grand Father Paradox/ Many-Worlds Interpretation)
IF you DON'T believe it, why not? Do you have examples and evidence to back it up?
LETS FUCKIN' GET INTO THIS M8'S



As always there are hidden secrets

go way you weeaboo.

Mhm, it seems pretty fictional at first, alright. But then again, there's the LHC (Large Hadron Collider), which if I remember correctly, tries to emulate extreme condition after the big bang? Dunno if it's true though. (https://en.wikipedia.org/wiki/Large_Hadron_Collider)

I need to see myself to believe in time travel.

Although it seems impossible to travel back in time, it is possible to move forward in time. This is where cryogenic sleep comes in where you can suspend yourself to move forward in the timeline, provided that you won't die while in the process.

Although you aren't manipluating the laws of time & space, you are fast forwarding the time.

Think of it like sleeping. You go to bed at 10 PM and go to sleep. Afterwards you wake up at 8 AM. It's due to you not remembering anything during that time period. Meaning, you're fast forwarding time. In a way.

God you guys fuckin' suck at these types of debates :P

Honestly, we should leave time travel alone.

I'm with Back to the Future about their opinion of time travel, being that if you try to fuck with the past, you could doom all of reality and life itself, calling all reality to crumble in on itself and implode into nothingness. It isn't worth the risk, even if it could reveal some truths of the past that people never witnessed.

The only acceptable time travel is forward travel, because you can't cause harm from traveling forward, let alone risk meeting yourself and causing a paradox that could make everyone D.E.D.

Still, humanity just won't let stuff like this go away, because they are filled with curiosity. Heck, it's why they're tryin' to make LHC, and it already sprouted some crazy shit, like some crazy girl, claiming she was from the future. Not to mention it successfully collided particles back in 2010. Here's what Proffesor Weiler said, copied straight from redorbit.com :

In our 3+1 space-time dimensions, the only ways found to time-travel and to remain consistent with Einstein’s General Relativity, require a form of matter never seen, matter with negative energy.

So my postdoc at the time, Chiu Man Ho, and I, asked if this unfortunate result might be evaded in a theory with extra dimensions, as is the case in a credible model called “string theory”.

Since gravity is postulated to exist everywhere that there is space, gravity waves or quantized gravity particles called gravitons should exist in these extra dimensions. Some string models allow certain particles, the so-called “gauge singlets”, which are postulated particles having no electric, weak, or strong charges, to also travel from our space-time into these extra dimensions. We chose a hypothetical relative of the newly discovered Higgs boson, the “Higgs singlet”, as our time-traveler. The choice was motivated by simplicity of the model, and the reality of the Higgs.

There are different versions of time travel. We looked for the version that produces “closed timelike curves”, CTCs.

These are paths that return a time-traveler, here the particle, to its starting point with no time appearing to have elapsed according to the observer, although time has elapsed on the particles own clock. In a CTC, any positive time of travel is negated by an equal amount of negative time of travel, as seen by the observer.

Returning to the starting point

We enabled the return to the starting point in a simple way: we assumed that the extra dimensions were compactified, meaning each dimension is closed upon itself, as with a circle.

Extra dimensions have never been observed, so we know that if they exist at all, their compactification radii are very tiny.

The compactification radius has to be large enough to contain the particle’s quantum-mechanical wave function, which, for our purposes, translates into a minimum compactification radius of 10^{-19} meters if particles produced at the LHC are to travel in the extra dimension. Being compactified and very small, these extra dimensions are clearly different than our large, clunky dimensions, and so may well have properties different from our known dimensions.

We were free to assume that the geometry of these extra dimensions mixed new space with our conventional time in such a way as to allow some particles to appear to move backwards in our conventional time (the math describing this process was first constructed for our standard dimensions over sixty years ago, by two Europeans, Goedel and van Stockum). We showed that a fairly simple description of the compactified geometry was consistent with Einstein’s equations extrapolated to higher dimensional space, and that the extra-dimensional space was void of all physics pathologies like negative energies.

We also showed that a particle may traverse the extra dimension many times, to arrive back at its starting point in our spacetime, BEFORE it left. In other words, that the cause-effect relation could be broken. For example, a time-traveling particle could decay into a flash of standard particles BEFORE the production of the time-traveling particle was apparent at the LHC.

In the words of my German colleague, Heinrich Paes, the particle would have no need to “remember” its origin; it could be said that now the particle “pre-membered” its origin!

If backwards time-traveling particles are to be a reality, then passing information, e.g. using the particle as a kind of Morse code, becomes possible. Then arises the issue that passing information to an earlier time may lead to psychological paradoxes. But Nature may be more imaginative than human psychology on this issue.

In conclusion

To summarize, we had to assume:

(i) the existence of compactified extra dimensions,

(ii) the existence of Higgs singlet particles (which would be made at the LHC in a mixture with the Higgs particle), and

(iii) non-flat spacetime in the extra dimensions mixing coordinate time with the new space-dimension(s) (actually, one extra dimension sufficed).

The odds of each assumption being true is perhaps small, the product much smaller, but that doesn’t matter - all that matters is the possibly whimsical nature of Nature. She appears to have given us one Universe. It may be simple as William of Ockham would have it, or it may be less simple as many of us would like it to be.

Also, speaking about forward travelling in time, you could either do FTL or Cryo method. When you go forward in time, and then you step outside a spaceship, it would seem to you that time only passed a year, maybe even a day. But in reality, Earth (or other place) passed hundreds, even thousands of years. Although, this is dependent on the destination, probably.
