Time Travel To The Past Impossible

If this is located in the wrong forum, please move it to where it is more suited mods. Ty.

This topic was sort of an epiphany I had the other day when contemplating the mechanics behind how a time machine into the past would function.
Based on what has been witnessed in fiction, there is usually some machine that a person clambers into/upon that then sends them back in time once the correct coordinates have been punched in ect.

This is where I stopped for a moment to do some comprehension. For you to be sent backwards in time two opposite things have to happen simultainiously.
First, whatever apparatus you are using would need to preserve the current time state of every particle youre made of.
Simultainiously, every other particle in all existence has to be reverted to a previous time state to recreate all of reality as it was "x" amount of time in the past.
As if this wasnt a big enough inpossibility, you must then map the physical location of where you want to pop up at because according to wiki, in a single year alone the earth moves approx 500 million miles and change.
Considering nothing in the universe is static and everything is in motion it would be literally impossible to make this calculation without compensating for every particle in existence and rewinding them all at the same time.

There is no currently known way to either map every known particle simultainiously, let alone rewind all of them but the ones you are made of. Even if this IS done, you have essentially destroyed every living entity in existence and recreated a new reality in which every particle in existence is placed in a new position. Essentially time travel into the past isnt even time travel as you are not rewinding energy back into particles, you are reorganizing the currently existing particles into a configuration that mimics what once was.

Any questions or thoughts are welcome, hope youve enjoyed the read as much as I enjoyed thinking about it.

Quantum physics might make it possible- if 2 particles can interact across distances- why not time? The particles seem to be linked in ways that tell physics to jump off, so time would probably be the same difference.

I've often had this thought about time travel too. If one could step from one time frame to say a past time frame, our Earth, even solar system could millions of miles away.

Read up on John Titor, there's a plausible explanation of how time travel could work, by using two mini blackholes and gravity sensors.

Since space/time is a single entity, if you are manipulating one, you are manipulating the other. Look into Kerr black holes, you'll find that black holes are theorized to be toroidal (donut) shaped, which allows approach to the singularity from certain vectors without being crushed by gravity.

By using two of them and manipulating their proximity to each other and injecting electrons to up their power you could theoretically manipulate the space/time surrounding them, using the gravity sensors to ensure that any severe space shifts don't occur.

There would be no way to check on a quantumly entangled particle if one of them is not in the present. Then you are not actually going to the past, you are just changing the information in a single particle, which if someone in the past were to observe that particular particle it would be randomly changing as we here in the present manipulate the entagled mate and no one in the past would understand why the information in this single particle was seeimingly randomly changing.

Because time does not exist in the natural and scientific world. What's there to travel through? Time concept is relative to our perception only, it's just a measure of distance, like miles or kilometers.

There are many scientific studies and research on this.

This may allow you to "view" events that happened both recently and in proximity of these black holes. They wouldnt be actually sending a person through time, that would involve the preservation of your time state and the destruction of everything elses. Viewing events from the past is already possible bia recordings. What i am talking about is actually going to the past in a physical manner.

This 3D reality, the shadow of higher dimensions, has a very good grasp on how everything holds together. No need for a machine to map every particle. You'll get a bit of a headache as the vibrations are a little different, but nothing to dissolve you into a pool of cells.

You should look into John Wheeler's One-Electron Universe.

It's an interesting idea, though it has not panned out and other theories fit the mechanics of the electron much better.

Tine doesnt exist as an objective constant, but it certainly exists. How else can I say something happened in the past, or an event hasnt happened yet? Because time is a real thing, just fluxuates in density.

a reply to: SummerRain

Unless you map every particle andtrace it backwards there is no way to know where you are going to pop up in the universe if you time traveled backwards.

Edit: I suppose looking at time in this way you could say time has 2 states, now, and not now. In order to know the location of anything in a time that is not now, you must measure the velocity, direction, spin, grabitational pull and electromagnetic force of every particle to kbow accurately where thing will be "not now"

Which is why I believe it is entirely possible. I would argue its already be I g done by a lot of individuals if not all in fact. That may not be the form we are used to thinking about, but that doesnt change it.

a reply to: sputniksteve

I cannot fathom a method of time travel that does not function in the manner i have described. Plenty of particles that existed in physicality centuries ago are no longer physical particles, but have been changed ibto energy one way or another. To truely time travel, you put rewind the energy onto the actual particles they were, which as science today knows it, is impossible. You cannot unburn ash back into whatever substance it was beforehand.

Edit: Otherwise you are just reorganizing particles to mimic what was, not rewinding back to what actually was.

I believe many of the UFO spotted around the globe is time travelers from the future.. observing important events.
UFO sightings is often related to historic events.

Time is just a construct to define a dimension.


If we can move within a 3-dimensional space, then why not a fourth?

I think you are correct OP if you think of time travel in the physical sense.
If, however, there is only now and everything we experience is just the present and our entire notion of history is just what we experience in the present as history, then it should be possible to go wherever we want to go at any 'time'.

There have been many, many instances of people slipping into past time. Are they all figments of their imagination? Who knows it may be ghosts are time travelers, ie. not really there physically to physically interact with the past but only observe. Similar to you looking at a history video. Because we have not yet (as far as I know) discovered time travel because we think it's too difficult is not the answer.

a reply to: crayzeed

It isnt difficult. It is impossible. You cannot rewind ash to the material that was burned into ash. Let alone reverse the state of every particle in existence to a previous state.

Even if that were possible, how do you simultainiously revert every particle in existence backwards to a previous state while keeping your own in their current state?
The answer in short, you cant.

Because those locations in the 3rd dimension stay those locations. Time is instanced and once a moment has come and gone you cannot go back to it. The state of particles has changed. Their location, what they are doing and interacting with have all changed. The dimension of time is constantly in flux. The physical 3rd dimension is a fairly stable place where locations tend to stay where they are, reletively speaking.

Yeah, let's just throw out those annoying rules like conservation of energy, information, etc., or say symmetry, who needs them anyway lol. If we can do the math like politicians do creative accounting, hey, we can do anything :-)
