      Yes. All you need to do is escape gravity, whether that be far away from a gravitational object, or by using velocity. After a year or 2, a clock on top of mount Everest will be ahead of a clock at sea level. But only by a microsecond. Time travel !

    What about parallel time lines or universes. When you go back in time and change something in your base timeline's history, you are initiating a parallel timeline that runs concurrent with your base timeline. In your base timeline, you still exist and so does your grandfather, but you're missing because you left it to go time traveling. In the parallel timeline, your grandfather is dead and your past self is never born, but you are still alive because you originated from a separate timeline. I think this is what you are referring to as "superposition" at 4:17, which is normal stuff in quantum mechanics.

  • @scottcupp8129

    Mathematics allow travel in both directions. But going to the future would be a LOT easier than traveling to the past. We travel through time everyday. At a rate of 1 second per second, we move forward through time in a forward direction. However, the faster you move, the more time slows down for you. Time is relative.

    If you eliminate time and instead assume that only entropy acts upon you, you also eliminate paradox's. Time becomes a singular moment, things are created, destroy other things to survive and entropy acts upon all things eventually destroying them.

    The very fact that you exist to travel back in time means that a paradox will never happen. The gun won't fire, you'll run out of gas, you'll change your mind. You can not change anything in the past that stops you from entering the time machine. Because it HAS happened it WILL happen. You can only cause ripples in the stream of time, you can't change the stream's course. I know, I tried.

    I was thinking it may be impossible, but if you are in a slower (clock), near C velocity, and also traveling slightly backwards in time, you would have more or less a FTL travel solution. Globally you would be FTL, and it would seem to have happened faster to the traveller.

    Also surprised how many smart people keep forgetting that going back in time and changing the course of an ancestors history even slightly would usually mean they would not have their exact kids in the exact same moment (conception) meaning it would be a different sperm and egg, meaning not the “you” - meaning you still didn’t exist.

Once the twin particle is altered or disrupted in any way the entangled particles which would be the emulsion on the film that was exposed by the entangled light photon. Once the entanglement connection is broken the emulsion will turn black.

    Time travel to an earlier point in spacetime is theoretically possible but it would logically require more energy than the Big Bang. Given that it would be possible to move all the particles in the universe back to an earlier point in time when everything in the universe was closer together due to cosmic expansion having been going on for a shorter duration. Our brains are capable of memory of past events by doing something similar but on a much smaller scale requiring less energy to move particles around given fewer particles to move creating a small scale simulation of the universe at an earlier time. We also do something a bit similar to time travel in video games with do overs which store information about where everything was at a certain save point which we can then return to.

    Travel forward in time. Travel a set mile and start at say 60 mph, then double it to 120mph, you’ve got there in half the time. Keep on doubling the speed until you nearly get there in a split second , then simply double your speed once more and a bit more to get there in no time at all. After that, The faster you go each time sends you further into the future. Ok it’s going to be quite fast which is beyond our technology but it’s an idea.

  • @potoker2296
    @potoker2296 Před 3 lety

    Theres most likely in early time travel a time dilation, which means string theory is the best way to explain the paradox of meeting yourselves in the past.
    Theres multiple universal dimensions that we all swap to every time a decision is made. Like the bit flipping aspect of dead or alive, it's the same with yes or no.
    Theres layers of dimensions that have everything the same as us but maybe only .01 percent divergence. Now with current particle theory when they look at particle clipping out of existence, it's only our existence not all the dimensions. We are either forcing or particles naturally are pushed into separate dimensions or timelines.
    This also acts on a wave function as well since as of right now we dont know where we are sending them or receiving them from, but with brute force approach ( 2 counterrevolution contained singularities with a particle)
    Theres expected to a divergence between our original point and the end point depending on the length of travel. Meaning the divergence gets bigger the further you want to travel, so in theory you could go back and see germany wins ww2, or you could go back kill your grandfather (I dont know who wants to do this but anyways) and your father or mother wont exist, but it never effected your original timeline/dimension. Only way to get this paradox is if you go back on your linear original timeline, but in that case you might have something happen to you as you go to kill your grandfather so you never actually can kill him. Cops picks you after reports of bright light, you walk out wearing the wrong clothes for the period or you just look sketchy called a spy, get sent to the CIA or FBI and now you are arrested but you cant go a kill him.
    I feel like time travel is possible but we cant go back to our original timeline, I expect there will be a divergence between your start point and end point.

    I want to pose a scenario and ask a question. First, the question(2), is there rotation inside a wormhole? Second, if so, can a counter rotation stall the effect enough to allow forward travel by a means of propulsion?
    Now for the scenario: a cigar shaped spacecraft is connected to a wide, circular band around- the band is connected with gears that allow rotation while the spacecraft remains upright and straight. The ship's rotaion field is positive, while the wormhole rotation is negative, thus acting against one another as in the field of opposite magnets. The ship, propelled by hydro-fusion and lithium crystals, is able to move forward and mimimize distortion.
    What does anyone think? Does it sound interesting to you?

    @edwardscott4535 Před 4 lety +1

    I created and traveled through a wormhole.Its really not that complicated once you know the basics.All you have to do is be able to manipulate space by pushing and pulling on it. Pull hard enough on a single point you open up a hole into the middle realm. (The space in between two dimensions ).That is when charged particles/exotic matter gets released which carries the energy to construct and power the wormhole.The charged particles look and move like sand being blown across the road.Then all you need is to accelerate fast enough by being able to skip space. I did it by pulling back on the space enough to collapse it onto itself.Once you have the forward momentum and your pulling back the space as hard as you can a vortex forms using the released particles and they will begin to emit a purple light.Now you have a worm hold. It is not hollow however, it is being built as you are traveling through it. So all you can see looking forward would be a particle dust storm inside of a dusty cylinder rotating clock wise.. I traveled forward in time with the one i had created. Only problem is after a couple of seconds looking around i was sucked back to to a similar time at which i had left but a different location from where i entered the worm hole. maybe about 3 miles ahead.But everything looked the same which ui then realised that every ones reality is based off of their own perspectives.So i am the first man to ever create an actual wormhole, travel faster the the speed of light, time travel and could manipulate time and space.And no one was there to see it, i don't think. If anyone saw me open up the wormhole in littlerock ca a little over a year or 2 ago let me no. i was driving a tan hyundai sonata 2012. I'm sure edwards afb has proof of the different things that i could do in that car. But i'm sure it would be considered top secret by now. Like teleporting off of a runway into the desert.

    I have never found anyone that can explain how the gravity part of this view keeps you tied to the earth. When I think of actual time travel happening, I always end up popping up in deep space after the earth has continued on in its orbit, leaving me behind. For once I would like to see someone explain how a person can be tied to the surface of the earth, so they don't end up in space, or above (or under) the ground due to the tilt of the planet as it changes through its seasons and travels in its orbit. I simply can't get past this happening, nor do I see anyone making any calculations to ensure that you are going to arrive at exactly the right time to have your feet planted solidly on the ground. I suppose that the fact that you would likely end up dead after materializing in deep space means that you wouldn't be killing your earlier self in any case.

    Basically the equation will be solved once the actions are taken, whatever actions they may be. Once you have hopped the time line, you have a unlimited ways to solve the outcome of the equation.

    The simple and definitive answer to
    the question of “Human Time Travel” is this; we haven’t therefore we never
    will. This assertion is not based upon astrophysics or quantum physics but
    rather simple deductive reasoning. Consider the following; if there were a
    point in the future where time travel became possible, it would of course be
    highly guarded to ensure it would not be misused (an oxymoron) by an individual
    or government. Much was the objective at the advent of nuclear weapons,
    however, time being the great equalizer, in just 74 years nuclear proliferation
    has created the very real possibility that left to its own demise, humanity
    will experience a nuclear holocaust. As with any major discovery, be it the
    combustion engine, flight, PC’s, cellular phones or nuclear weapons, no matter
    how astonishing it is initially, in time it becomes common and accessible.
    Thus, if human time travel were ever possible, given our propensity to misuse
    power, humanity from its conception through today, would be in TOTAL disarray
    and PERPETUALLY in-flux. We are not, and there- in lays the proof that human
    time travel will never happen. Humanity has shown that it simply is incapable
    of possessing such awesome power responsibly and as such, time will forever
    remain in the realm of an omniscient God.

      In terms of time and spatial distortion, cobsider the movie starring Angelina Jolie, where she and her cohorts shoot bullets that twist and turn, around and past objects to only hit their intended target. That is distorted fabric!
      Perhaps flux really does exist; (Dragon Riders of Pern-Anne McCaffery). When a person leaves the hold, a village, they enter the space called flux. It is a fog that wobbles, and shifts in its own space-fabric. Maybe, in this flux immediate movement is possible with just a sliver of exertion, and in so doing, one travels to a far away place in a nanosecond. Just some thoughts for you.

      Similarly today we don't know, what our future is gonna be like, may be we'll discover some new stuff called time machine.
      Today we think time is a measurement but what if it turns out to be totally different?

    • @andrew_841
      @andrew_841 Před 4 lety

      This would be a fine way to see time, and would close debate, if only it wasn't for the block universe. See the block universe states that time, space and all other dimensions all coexist inside of the block, which is what we think of as the universe. Meaning that down to the atomic level, changes can occur such as photons splitting into different realities as we have no idea what is happening when we don't observe it, basically we have no idea how to disprove the multi-reality theory.
      This means that a literal infinite number of timelines / realities can exist inside the universe and that all time coexists as well, you could call it "seconds" or "fractions of seconds" but really time is smooth and basically uncountable, but that also means that all time is equally as real as the last. Hence why the actions of the past effect the present and the future all at once. Also could be why time effects the universe and biological life in so many ways, another odd example is how when you take a video or photo that moment / moments of time is now recorded and you can go back and observe it at any time.
      Another interesting thought is that the main theory of using travel into the past being a wormhole, say a wormhole between point A. (5257 A.D, earth) and point B. (2020 A.D, earth) exists, atoms would basically always be moving in and out of the wormhole for eternity, meaning that atoms are literally time traveling at a constant uncontrollable rate. Meaning that time, is basically a place as well.

  • @MrSKaTeR0709
    @MrSKaTeR0709 Před 10 lety +2

    We have already done time travel but it is only in the past. Because we have to use light to see the past. Like if you see a quasar or anything in the sky. It takes time for that light to get here so that means we are seeing its past self not its present self and that technically it applies to everything because light is not instant because It takes time.

  • @friedeggsonpancakesmad9525

Even if you’re unlucky enough to get back a thread that hums close to your home one you’ll need buckets of meds to damp down the constant deja vu

    No need to involve parallel universes, universe remains "uni"-verse but it is not a conventional universe we perceive as such it is the quantum universe in its superposition, from this perspective the time from point of view of classical observer should be considered as not a one-dimensional but rather like branching bush/tree, all branches are real but not equally probable and in fact, each observer grows its own tree, its shape depends on the decisions/actions/thoughts observer made through his life; it's clear that "observer" in this context is not a classical observer but rather an assembly of the same observers in its different superposition states.

    In order to understand.
    You need to look at all time machines invented and see which one is theoretically doable ..
    I settled on the Wells machine.
    I divided it into three stages of work .
    The disk / the Leyden jars/ the accelerometer.
    The disk I got spinning on its own and generating lightening.
    The disk needed to be rewired so I rewound time .
    I find it very odd nobody tried to fix the Wells time machine.... so I decided to see if it actually works at one time .
    When the disk spins ... it forms energy at the Center of the disk ..

  • @gregkopacz2136
    @gregkopacz2136 Před 3 lety

    Let's say in theory, it's possible to travel faster than the speed of light or use the wormhole theory to bend space and time to travel a great distance quicker. So say I'm able to view myself with an extremely high powered telescope and able to shoot a bullet faster than the speed of light back towards earth (again I'm able to break the speed of light or use worm hole theory to pin point where I'll come out), then in theory, I'm not using the multiverse theory considering I'm on my same plane, and I could theoretically execute myself.

Then, you decide to return back to your time. You arrive on July 4th, 2019 at 9:45 am. Now, there are 2 of you. One of you, gets into the time machine at 10:00 am. He decides to go visiting the past and returns back to his own time on July 4th, 2019 at 9:35 am. Now what happens? Are there 3 of you in the same room?
