how would time travel technology work suppose it was real??

Look up how flux capacitor works

The EM drive will allow us to travel faster than light, thus allowing us to time travel.

but you can travel through time, slowly and only forward

It wouldn't

I have a time machine.

Well I usually like to refer to John Titor's theory of time travel.

If time travel were to be invented, it would have to come after the invention of both interstellar travel and worm holes. we would create a worm hole next to a black hole that leads back to earth. Relativity would slow down the worm hole on the side of the black hole, and after 10 years or so it would be a time portal back to 9 years and 6 months ago.

Reminder there is no proof of parallel universes so if time travel was real then a human would have come back in time to bring us time travel

By the multiple universe theory, you would be kicked to a parallel timeline where "you appeared from nowhere", so you can't go back to your own past.

Or maybe people who are using it have created a monopoly on time travel and it's restricted, as it should be

yeah this is the real problem, you can't go back because it causes a paradox but you can go to an identical parallel universe, assuming there's an infinite amount of them, and change the past.

Then you'd go to the future of this newly altered parallel universe to reap your rewards, but if you go back again you wouldn't be able to go back to the past of the currently altered parallel universe from whence you came, you'd go to a different one and then to this new ones altered future.

Problem with that whole scenario is if there are infinite universes to muck about in then everything would constantly happen and not happen at the same time in all universes at once because infinity works that way.

Moving forward shouldn't be an issue though, well until time stops existing I suppose.

Time is a vain attempt at the quantification of the continuous flow of state transitions within the universe, there is no such thing as a start and end point as much as you can't say what state of matter water originated from, only the state it's currently in given the temperature.
I suppose there might be a way to manipulate things on a local scale, but that's essentially no different than tossing a steak into the freezer, time reversal on a cosmic scale can't exist because no imprint of what it used to be like exists, only its current existence at any instant in time.

Would be like tree branching. You can't alter your own timeline but you can alter others.

Lets say you went back to the past 10 years. Then you killed your past self. Conventionally people would think "paradox" and "you cease to exist" but realistically, it just means you've now created a new timeline that deviates at the moment you stepped into the past.

Think of it this way, we currently operate under Quantum Immortality/Suicide/etc rule. Where you are immortal and you never die because each time the chance of death occurs, another portion of you survives. This line continues forever and you never truly die in all aspects of the quantum universe.

This application can be applied to time travel and ontop of time travel as model.

if you travelled back in time, the earth would be in a different position and you would likely appear in the middle of space and die instantly.

You trick the mind that simulates our reality to do it for you however it sees fit, but I bet that mind motives are beyond us and most probably it's incomprehensible big and most likely we won't go wrong if we call it omniscient at least within our maximum spheres of understanding.

Going to the past is impossible, the universe doesn't save the past. Other universes that have similar pasts to ours but are happening right now might exist.

If we knew we'd have built it

The notion of motion and causality is bit wonky as shown by the likes of ancient greeks/indians.

Assuming a linear notion of the universal time is thus simply an assumption, but one thats rife with problems.

The understanding of motion can be understood just like how we do animation and movies. Bunch of snapshots. So to say "the past doesn't exist" is absurd. Same with saying "the past exist" or the future doesn't/exist or the present doesn't/exist. They are absurd in this context. They all exist in same time, its only the perception that changes whether its past/present/future. We also don't understand what our perception is or how it works.

It wouldn't work. Time is an expansion of space. To reverse time, you need to reverse this expansion. But everything in the expansion would reverse, including the construction of the time machine. Thus, when you pull the lever, time essentially stops, since you reverse it by 1 second, reversing your action, allowing time to expand by one second, and the cycle infinitly repeats, as your constantly doing an undoing your actions

If we created our own virtual reality which was identical to this reality, then 'time travel' would be extremely easy.

If THIS reality is a simulation, then I'm sure whichever entity runs it can run their backups/time travel/what not. The problem is they've created a simulation so vast and big that there's really no reason they'd ever do it unless the universe was coming towards its death

>they've created a simulation so vast and big
Ever played any MMO games or any games?

The tech is called GPU fences. You only utilize local events, nothing more.

Primer has the most realistic version of time travel I've seen.
They invent a machine that reduces the weight of objects and by putting a watch in it they find out that whatever is in the box exists outside of time. Not exactly outside of time, it turns out, but time in the box moves in reverse. So you get in the box at 10 AM and stay in an hour and 30 minutes. You'll back at 8:30, and eventually your double will get in the box, so two of you only exist for a short amount of time.You can only go back to the moment the machine was invented because if you try to go back further then your double has no box to get into. There's also health implications from being inside the box although they're never fully explained.

thats why you put a tracker in the earth to follow it dummy
