Do you think time travel is possible?
I always ask myself, what is time? Does time exist? Eastern philosophy states that there is only one moment, and that is now and that our brains just construct the abstract idea of time since we think in a linear way. We can’t even imagine what its like to think non-linear, in the same way we can’t make up a totally new color, its outside our capacities. Also, Einstein figured out that time is relative, it depends on our speed. The closer we approach the speed of light the slower time goes relative to others who move slower. So physical objects can never time travel, as in, go back or forward, because E = mc^2 and thus you need infinite energy. If you think your consciousness is not physical, maybe you can, as tibetan buddhists claim.

I agree with Martijn. Time is just something we’ve made up to help explain memory / the concept of past vs. present. Check out this article I wrote waayyyyy back at the beginning of HighExistence. It explains Einstein’s take on this perfectly: https://www.highexistence.com/einsteins-theory-of-relativity/
Einstein once said ‘Time is just an illusion’… If that is true, then that means that ‘time travel’ could exist… Well not time travel because at that point time wouldn’t exist, but being able to move back and forth between moments… I don’t really know how to explain it, but somehow it seems possible to me… and what about teleportation, telepathy and telekinesis?
yes; it is something we can do…you can visit your past lives…or the past…or the future…you can explore other worlds and other levels of knowledge…it just takes practice and an open mind :D
No, time travel will never be possible in the classical “Hollywood movie” sense for the sheer fact that time in and of itself doesn’t exist. The only thing (with regard to time) that exists, is now. A better way to think about time is “duration”. Time is only a construct used to measure and delineate duration. Future is only potential, which is intangible.
And so, if the only thing that exists is now, then the past doesn’t exist in any tangible sense. If the past doesn’t exist then how can we travel to something that has ceased to be or has yet to be? We can’t.
This does not, however, account for the multiple universe or infinite realities theories. You could, in theory, travel to an alternate reality in which something has not happened yet or to when something has happened already. However, if you travel to a reality when “something” has happened, you would still have no way of knowing whether the “something” was ever even a part of your original reality’s future to begin with. (lol)
Now, that being said, I’ll take it a step further: earlier I said that the past doesn’t exist in any tangable sense, which is true. However, we remember the past. Sometimes very vividly. But that memory of the past is unique to each individual, as everyone experiences “now” with their own personal bias. So, one may be able to “travel” back in ones own manifestation of the past in a sort of “butterfly effect-esque” way however, without the ability to change any events in reality.
I agree with martijn, time travel will never be possible. It might be possible way in the future but I think only moving forward would work and you won’t be able to go back. And isn’t it if you move real fast you pretty much time travel. I saw something on the history channel where they might be able to move at the speed of light but they need dark energy, they can already produce it but it’s such a small amount.
Moving fast doesnt equal time travel. In order to time travel a object must move through a timeless space. By that i mean the Someone would have to be able to stop all matter from moving for a given period of time, to travel.

Like Martijn stated, time is an illusion. Time is really just where you are and your current speed. In the quantum world, everything is basically everywhere, therefore, you are everywhere, everything is everywhere and linear time is really just one solid point. However, this universe consists of the observer (consciousness) and the observed (matter). The observed and observer are one in the same. In your finger nail is the cosmos and Shakespeare, if you really think about it. So in that case, I suppose time travel is possible.
@blankey, I’ve always wondered if other dimensions are transcendent or not. Something came across my news today speculating that other dimensions have the potential to literally hold space inside of it, but we could be looking at it without even knowing. So within this 1 dimensional point or something, contains an expansive new dimension. But, perhaps there are dimensions that is outside of this time/space construct, and if there are, then perhaps going back in time the way we would imagine is possible, but only via other dimensions.
@entropic, I could not explain this any better, I agree with everything you say. Time travel will never be possible within one period/timeline. The only possibility to time travel is to go to another (parallel) universe/life or however you want to call it. But would it then still be time travelling? And we invented time, it is not something that actually is, because we live in the eternal now; there is no other moment than the now.
@cecilia, No. The grandfather paradox.
The future you can easily get to. Just read relativity theory. You can’t “Skip” to any point in time, but you certainly could go to any year you wanted to in the future, provided your body and space ship can withstand gamma rays from the background radiation of the big bang :)
Damn you universe! You always have a trick up your sleeve.
In one case, you can travel to the future, but it is not so much time travel as cryogenic suspension. Technically, if you could travel faster than light, or fold space like a worm hole to a far off part of space, then you had a device that could convert light reflected off the Earth, as far as it exists, into an observable image, then maybe you could view the distant past as it unfolded, but probably only day time (like that makes it more realistic, ha)
@ijesuschrist, I do not agree with this. I think you cannot go to the future of this timeline we live in. Maybe it will be possible to go to another future in another dimension but definitely not in this one. See this video about 10 dimensions for a better understanding
And are we not travelling in time when going from on continent to another continent already? Why does the USA live in another time zone (in the past) than Europe? When it is 8 hours earlier in the US than it is in Europe, does this not mean that the US lives in another time?
Watson: What do you think, Holmes? Would time travel be possible some day?
Holmes: Only time will tell.
