    Astrophysicist Neil deGrasse Tyson explains the details behind backwards time travel. When we were kids we wondered whether we can travel into the future or go back in time using some sort of time machine.
    Neil deGrasse Tyson also explains how and why we know we can travel into the future. Special and general relativity, suggest that suitable geometries of spacetime or specific types of motion in space might allow time travel not only into the future but also into the past.
    Perhaps the best way to go back in time is to make use of traversable wormholes. Neil Tyson explains all the intricacies of going backwards in time using a wormhole
    Another exciting approach for backwards time travel, involves a dense spinning cylinder usually referred to as a Tipler cylinder.

      Well ya gotta remember that what we think of as the past present and future actually ALL coexist simultaneously. We only conceive those notions because of the speed of light. So if you were to “go backwards in time” you wouldn’t be aware of it - you’d literally be reliving the “past” all over again - making the exact same choices, meeting the exact same people etc. This is why you couldn’t go back and change things.
      This is also why it’s impossible to travel back to a time before you were born.

  • @somersetcace1
    @somersetcace1 Год назад +53

    I think the paradox would be dealt with, IF each movement back in space-time then created a whole new branch of space-time at that point. So, you go back to 1900 and from that point there becomes now two divergent space-time branches. The original branch then remains unchanged because your self is no longer on that branch after whatever point you leave. Each time you move forward or backwards a new branch is created, meaning you keep moving `forward` in a relative sense through each new branch you create, regardless of where it is on the timeline. In that case, you could kill your parents before they had you and avoid a paradox, because `you` weren't born on the space-time branch you killed them on and *that* space-time branch still exists unchanged to the point you left it. There's not a shred of scientific evidence to support that idea though, so it's kind of just mental fluff. What would it take to overcome that paradox?

      There is a thing that is possible in theory, it’s to observe the past. With a theoretical warp drive the theoretical upper limit of speed is ridiculously high. If you have a huge planet size telescope (gravitational lens) you have the chance to look back in time. Just as we see only the past through our lenses, if we leave Earth with extreme speed and look back on it with high enough mqgnification we could see our past. With the speed and distance you can calculate how far you want to look back. So theoretically we could have a look on dinosaurs or whatever. Fun thing to think about it.

    Doc Brown, in Back to The Future, illustrates why travel backwards in time hasnt happened, nor will it. Not only do we all live the same space time continuum, we all live the only space time continuum. Travel backwards in time creates a new continuum that, no matter how minisule in degree change, eventually becomes vast over time - erasing us all.
    An example would be charting your course across the ocean for a distant lighthouse thousands of miles away. If you start your voyage 600 meters away, a minisule error stills lands you at the lighthouse. However, over thousands of miles this small error lands the Voyager nowhere close to the lighthouse. Indeed, the lighthouse would likely not even be seen.
    Any interaction with the past, no matter how small or seemingly insignificant, changes the trajectory of time moving forward which, like the misguided seafarer, eventually removes earth from its destination.

    Lets get one thing straight. If you could travel faster than light you would indeed be traveling backward in time. However it is IMPOSSIBLE to also remain in the same place. In other words you would not be able to travel through time alone. Which means you will always travel a DISTANCE in order to go backward. If you tried to return to your starting position you would in fact have to travel through the Bulk( If it is a thing anyway). The only way that this works is if you travel to a distant point faster than light,( So you travel back in time) then you would have to turn around and travel back to you starting point at sub-light speeds taking the length of time equal to the distance traveled. The wormhole is only possible for that brief period that you travel at FTL speeds. You would end up at your destination near instantly. At least this is the way I think about it. It could also be the case that the only way to travel through time is to use an engine that would instantly launch you through a wormhole to the same point in space but backward in time, however this would require all the energy of the universe, I suppose it might be possible to only create a local distortion but I doubt it. Locally it would create a new separate timeline, if in fact you could build up enough energy sitting still (relatively speaking) to instantly launch into the past. It would have to be a instant transition otherwise you would end up as paste on the bulkhead. I still think my first thought is more accurate though

      It still wouldn’t allow you to go to a period of “time” of past events. “Time” is just a certain amount of units we measure daylight in dictated by the earths orbit around sun. Other planets have different “time” speeds. It’s truly a misconception when people say you can time travel. If you traveled 5 light years away and then traveled back to your starting point at regular speed, you’d be the exact same age the day you returned. A 40 year old man is still a 40 year old man whether he’s traveling super fast or not and he is still dead after 5 light years the same as the person on earth would be dead. Deterioration and aging is still a thing even if “time” travel is possible. Which it isn’t in the idea going to different places in history.

    • @LordFirestaff
      @LordFirestaff День назад

      In my opinion, speed does not affect time. Traveling quickly through space does not equate to preserving time relative to another person; it simply means covering more distance in less time. Time is the same everywhere in the universe. It all ages at the same exact rate. Traveling at the speed of light would not cause you travel backwards or forwards in time; you're just moving through space rapidly. Where you end up will be the same time no matter where you are. If I were able to travel to the nearest galaxy instantly, there would be no time dilation. I would reach my destination at precisely the same time I departed from Earth, plus or minus a few fractions of a second, since even an instantaneous journey would involve a small measure of time. Though, if I came back to Earth a few seconds later, nothing would have changed on Earth except for the few seconds that passed during my trip.
      Regarding light, it's true that we are, in a way, looking into the past when observing distant objects like galaxies and stars. This phenomenon occurs because of the time it takes for light particles to travel across vast distances before becoming visible to us. The time it takes for light to travel to us differs significantly from the actual time at its source. The light we observe may have traveled for millions or billions of years before reaching us, allowing us to see the universe as it was when that light began its journey. However, this does not imply that we can physically travel back in time. If a beam of light from a distant star reached Earth at this moment and you could instantly teleport to that star's origin, you would see the star as it currently exists, rather than the light we observe from Earth. The star you traveled to may not even exist anymore. Watching it feels akin to viewing an old black and white film. It's like reviewing a tangible record of events that occurred in the past but have since ended or changed significantly over time.
      Also, consider how we use phones to communicate. If I'm in Texas and make a call to someone in France, we're speaking and seeing each other in real time for the most part. Though the speed at which our data moves may cause a slight time delay, we still exist in the same time. If I were in Texas and my friend was on Mars, there would be a time delay from data having to travel that far, though we still exist in the same time. I'd essentially be seeing a recording of my friend rather than seeing him in real time, but that doesn't mean either one of us has moved into the future and/or the past. Time is constant and moves in one direction at one pace, forward and steady.

For example, let's take the famous grandfather paradox. Let's assume that someone has traveled back in time and killed his grandfather. In that scenario, his actions won't be affected to his timeline or future. It will only make a branch alternative timeline, which is connected to the main timeline, where his grandfather is dead. In that way they all make sense.

    When I first began to learn programming I wrote a python script to calculate time dilation when traveling to and from alpha centauri and one of the things I observed was when moving at 99% the speed of light any small increments to speed can yield massive differences in the result. Now this was years ago but I somewhat recall the result was like 125K years into the future moving at 99% but as soon as I start adding that .9's I was easily able to produce leaps in the millions.

    Regarding the grandfather paradox: what if all of time -- past and future -- has already been written and set in stone. I.e. we experience the present moment, but our future is already predetermined. That means, if someone were to go back in time and prevent their own birth, they simply would not exist and so that possibility is wiped out in the first place -- meaning NOBODY has the ability to even attempt that in our universe. However, if someone went back in time and did not affect anything with their birth, then this is allowable and so this person may exist.
    Basically, anyone that decides to affect their own birth via backwards time travel must fail, or else we wouldn't know about them as they would not exist in our universe at all. There may be people who want to meet their parents, but they would fail to prevent their own birth. It's the only logical way that this paradox can be explained whilst permitting backwards timetravel.
    In summary, the life you are experiencing right now is only possible because you and nobody else in humanity went back in time to do anything that prevented you or them from being alive.

    We cannot travel back in time for a simple reason: the entire universe would have to revert to the size it was at the time we want to return to. This is related to Einstein's theory of relativity, which states that time and space are inextricably linked. Every point in time is also a point in space, and therefore, traveling back in time would require recreating the entire state of the universe from the past, which is practically impossible to achieve.

    No matter where you live on earth, what color your skin is or what your religious beliefs are, we are all the same immortal, spiritual, cosmic beings of light, vibration and frequency, who love and cherish each other beyond scope and measure when we’re back home together. Most of you, except a very tiny percentage of the population, have forgotten who you really are and where you’re actually from and that we are from one collective source (the creator of all) of energy in the cosmos. Some believers will call this reality or realm ‘Heaven’ or ‘the other side’, but whatever name you do choose to call it, the bottom line, it’s been our true spiritual home since time immemorial. Don’t fear death, there’s nothing to be afraid of because you are going back home to your countless love ones you’ve made over eons of time and space.
    It’s all the same to me but some people find comfort with labels and there’s nothing wrong with that I suppose. I do believe though, the word ‘Heaven’ has gotten a bit misused over time, because to me it’s not a place you can go, but a feeling of belonging and acceptance and love beyond your wildest imaginations and dreams and desires for the one, known only as, ‘I AM’. Your consciousnesses and your soul are one in the same. Earth is not your real home. The place your consciousnesses goes when you pass away, is all the same thing and again it’s where our spiritual home really is. When you do cross over, It’s simply a matter of closing your eyes here and immediately reopening your eyes there, It happens instantaneously.
    Actually it happens so fast that most people that have NDE’s (near death experiences) say that at first they didn’t even realize they were dead for a while. Even the ones that died on the operating table in the hospital, for example, have said that as they were out of their bodies temporarily and floating up near the ceiling, they were wondering who was on the table below in the room because they just felt that there wasn’t any way that person could be them. Only when they don’t get a response from someone in the room or suddenly walk through a wall is when they realize something happened to them. You have all lived many, many lifetimes through reincarnation, quite possibly thousands of times, perhaps more.
    More than likely, you have been every race, gender, ethnicity, color, even every species throughout all the billions of galaxies and the cosmos and lived from every time period going all the way back to the very first inhabitants of every planet that contains life. Again, you are immortal and have died so many times throughout the spectrum of time. Every time your soul comes back to a new being, you and your soul guardian, or as some people like to call them, their guardian angels, will pick your life’s blueprint of what you’re going to do and accomplish. You’re not meant to remember this most times, but there will be some instances where the source creator will let you retain your memories from your full existence and you’ll get to remember them during your journey throughout that particular lifetime’s span, for reasons the source sees fit.
    If your memories are removed for a particular lifecycle, the creator wants you to discover this throughout that lifetime and on your own, learning lessons from it. If everyone was just told what they had to accomplish or learn every time, they wouldn’t be able to properly get what was needed out of each life. The core learning for each soul and every life time is the ability to love one another and show compassion for each other. For some beings this takes a bit longer and they may want or need to keep coming back until it’s accomplished.
    For most beings though, I’ve heard they want to finish the lessons and be done with it for good, stating that life on primitive planets such as Earth, is just to hard and they want it to be over with. I would have to agree with that sentiment, life is hard on Earth unless you were born into a family that has everything and everything is done for you and on top of that, you were blessed with wonderful looks or talents that leave you never wanting for anything at all. It’s a fairly low percentage rate of beings this happens to but we’ve probably all experienced a small amount of success in one of our lifetimes or another.
    Please stop the wars and fighting amongst each other and start to love one another, as it should be. We are spiritual beings having a physical experience, not physical beings having a spiritual experience. Jesus said on the cross: “Father, forgive them for they do not know what they are doing”. Maybe we will be able to do the same one day, forgive our enemies. I will get some comments sometimes saying, “some don’t deserve it”, but that will be between, them and the creator.
    If you want any other perspective or guidance on this information, watch the programs called: (The Ghost inside my Child), and NDE’s, (Near Death Experience) testimonials. Most of these are on RUclips. There are many different channels on RUclips with different hosts, so try if you can to eventually watch them all. No two experiences are ever the same and all have different information that others won’t have. The more you watch and learn, the better of an understanding you will have of everything I have mentioned in here.
    Please watch as many of these videos/episodes as you can, because you will get a broader, more detailed understanding of what it’s all about and what’s to come. I promise you, this will completely change your life for the better and you will never fear death again. Some of you have said, “it’s the fear of pain” that you associate with death that you fear mostly and I get that as well believe me. Nobody wants to die of a painful or agonizing illness or disease, especially something as terrible as cancer for example that can go on for years sometimes. It will also give you a complete sense of peace and perspective for all things in your life.
    You will become exponentially more compassionate towards people and even animals once you learn the truth about it all. You will learn to love yourself first and foremost and that in return, will help you learn to love others better as well. I completely understand if you can’t and/or won’t initially except some of what I’m telling you. But I do hope and pray that you will try to expand your mind from what you’ve been taught. Trying to get rid of what you were taught since birth and accept something completely new and what some have called, ‘fantastical’ isn’t the easiest thing to do, especially if you like the way things are in your life and don’t except change that easy.
    I myself have been accused by my family and friends for being what they have called ‘Pig Headed’. I’m not that way anymore, I have completely changed since learning the truth. I’ve had some ask me about the situation with babies or young children and cancer or illness, disease and ‘why god takes them at such a young age’. Saying, ‘how’s that fair, they didn’t do anything to deserve that’ or ‘why would they pick a life just to turn around and die’. I initially had issues with all that as well, but over time and learning, it became clear that sometimes the life blueprint that’s picked, is not always about you, but those you choose to be born unto.
    A mother or father may need to experience or learn humility or sacrifice and yes, sadly the suffering for the loss of a child. I know it sounds cruel but for whatever reason, it was ultimately necessary and the creators plan. We’re not meant to know or understand everything, that’s essentially in the creators hands. I was a nonbeliever and hardcore sceptic when I first heard about this information but the more knowledge one learns and acquires, the more you will realize it all to be true and not just a ‘nice story’, as one guy responded back to me recently. Please don’t ignore this, it has everything to do with why you’re here. Some things are true whether you believe them or not. I would like to say though, that I’m not in any way an expert on the subject or claim to know everything, not even close. I encourage you to do your own research and come to your own conclusions, have a blessed day or night.

      Temporal Infraction
      Developing a physical theory around the idea of "temporal infraction," where the day still has 24 hours, but the value of these hours decreases, involves a series of assumptions and extrapolations that mix theoretical physics, philosophical concepts, and the subjective perception of time. Let's explore this idea in a structured manner:
      1. Definition of Temporal Infraction
      Temporal Infraction: would be a condition or phenomenon in which, despite the objective measure of time remaining constant (i.e., a day still has 24 hours), the "quality" or "value" of this time is perceived as diminished. This reduction in the value of time could be quantified in terms of efficiency, subjective perception, or capacity for achievement within a time period.
      2. Initial Hypotheses
      Temporal Dilution Hypothesis: Propose that there is a dilution of temporal experience, where each unit of time (hour, minute) becomes less "dense" in terms of quality or utility, similar to the concept of entropy in thermodynamics, where the system tends towards a state of greater disorder.
      Subjective Compression Hypothesis: Suggest that there is a compression in the subjective perception of time, where the human brain processes time in an accelerated manner, making it seem like less time is available.
      3. Mathematical Model
      We could model time not just as a linear dimension, but as a function that depends on psychological, social, and even cosmological variables.
      If T24 represents the 24 hours of a day, we could introduce a "temporal infraction" factor I(t) that modifies the perception or value of these hours:
      T24' = T24 × I(t)
      Where I(t) is a decreasing function of time (t), representing the decrease in the perceived value of time as days pass.
      4. Physical Interpretation
      We can hypothesize that this temporal infraction is caused by external or internal interference: External Causes: A cosmological phenomenon that affects temporal perception, such as a variation in the expansion rate of the universe, which could influence how matter (including human brains) interacts with time.
      Internal Causes: A neurological or psychological change that, over time, alters how human beings process the passage of time, similar to how gravity can bend space-time in General Relativity.
      5. Experiments and Predictions
      To test this theory, we could: Measure the subjective perception of time in different populations over time, observing if there's a tendency for people to feel they have less time as they age or in different seasons of the year.
      Investigate if there's a correlation between cosmic or geophysical events and changes in temporal perception.
      Develop computational models that simulate how time perception can be affected by psychological and physical factors, adjusting the I(t) factor to predict different scenarios of temporal infraction.
      6. Conclusions and Implications
      If this theory proved true, it could have profound implications for how we understand time, both in a physical and subjective sense. It could also influence how we organize our lives, from structuring work time to valuing leisure time.
      This "Temporal Infraction" theory is an attempt to combine physical concepts with human perception of time, exploring new ways to understand how we experience and value time in our daily lives. Although still purely speculative, it offers an interesting field for future theoretical and experimentalexplorations.
