I figured out paradox a while back.
Time is 4D, the fourth coordinate & squared space, does that make humans 4D?
No, we aren't beings beyond space as we are bound by 3D, but 4D causes movement & existence so we have a 4D ability that makes us living organisms or entities, as a 4D existence would have body that could simultaneous move in absolute time as in the past, present & future.
When we go back in time we erase & rewind the timeline so it no longer exist, then you shouldn't exist too right?
Wrong, as we aren't the timeline itself only esteemed from it, an entirely separate concept & entity, only if time or space the concepts holding us together cease to exist will we also perish.
Basically nothing happens to you if you destroy any possibility for the future you to be born as it's building an entirely different timeline with you in it, a new timeline with an infinitesimal amount of future particles in the present verse that's all.
A timeline jump places you into another alternate timeline from the same verse or another of which there are infinite timelines or more, which of course doesn't affect the one you left behind.

perhaps it is but can we see the real past on a giant time travel machine [like the THE TIME TUNNEL screen]. What would happen if a time traveler went back to 2007 to the LA UMG Archive and get all the masters and brought them back[knowing that in 2008 they were destroyed by fire] you'd need a big carrier or you did it in stages. What would happen to the tapes. 1/would they remain in your time or would they actually disappear automatically. if the object disappear you'd have to make a copy, right or wrong. There is a pro to going into the past with a smartphone 1/ you could take photo's of famous kings, queens as far back as possible and WRITERS ETC AND BRING THEM FOR US TO SEE. VIDEO A CORONATION OR SOME OTHER EVENT. go back and see the birth of Christ or into the crucifiction of him in 33 AD. or the burning of Rome AT NERO'S TIME AND WITNESS THE EVENT. But to kill one's grandfather or father is impossible or some dictator. Another thing people in history if you travelled through time you could not/or could you tell a famous person or royalty their demise date or something of that nature. Just my 2 cents worth.

The problem is, that if we assume, that you could just appear 100 years ago and meet your ancestors, then you could appear 5 minutes ago as well, and meet yourself. where exactly? Two steps from where you're sitting now? Then what would exactly happen in the moment, when time starts running backwards for you? Would you split in two persons? That would kill both of you i guess. So we must assume, that you would just dematerialize from one place and time and appear in another. What sounds quite unlikely.
HOWEVER. Lets assume, that you can do it. You just disappear from present and appear in 1989, april 12, 11: 52. Only. where, exactly? Earth moves trough space with speed ca. 30km/sec. Would you appear back on Earth? Same location on Earth, but not the same location in space anymore? And if yes, what if. somebody's sitting exactly in your 'landing' area? What if you'll go back 70 mln years in past, and appear right into some dinosaur -ss?

Observing the past is quite easy, just look through a telescope.
Knowing that, you could also look at the earth in the past by placing a mirror somewhere far away, possibly with some substance in front of it to slow down the speed of light.
This way, for example a murder being committed outside, with no clouds blocking the view (or with the use of a telescope cabable of viewing other parts of the spectrum, on the side of the earth facing the mirror, it could be witnessed and not be prevented, but at least you could solve the murdercase more easily and accurately.
I think that's the best we'll be able to do when it comes to observing the past, apart from having camera's taping literally everything, everywhere.
Travelling to, or altering the past makes no sense and is forever impossible, I believe.

Although time travel is impossible, it have always fascinated me. The other day, I had a really awesome dream that looked so real that it looked like a movie. I dreamed that I was walking down the street in my neighborhood (I live in a city) and saw 1980s cars. According to my dream, I traveled to 1989. I didn't speak to anyone. Everything looked so surreal, and I was thinking -if people would know am from the future-. So I kept waking and thinking that everyone was living in 1989, and everything already happened. I didn't modified the past, I even didn't interact with no one. I saw the people walking, crossing the street. I saw the traffic. I heard the typical city noise. I think it was evening rush hour like 6pm. I felt so good, and I still remember this dream as I watched a movie.

You see? When you time travel, be prepared to lose something precious to you as well. The loved one youve met, the camaraderies from your team and their trusts being given to you, the skill that youve learned and some good times that made you alive again. Are you willing to lose all that for your own greater good?
I suggest keeping a backup mental hard drive for yourself just in case if you lose an important memory, you can install it in your head from wherever timeline youre gonna travel into.
Just a warning. Happy time traveling and be safe whenever your tomorrow is, always!
-Shhh, been there done that. No just kidding. Ignore this please-

I like to think of time as a branching tree every dicision even small things like moving 1cm to the right creates a branched timeline and when you go to the past you are simply creating a new reality from the point you went back to meaning that if you return to your present nothing changes because you simply created a new timeline unless you happen to travel to the future of that new timeline in which changes will be present and whether you exist in that timeline is determined based on what you did in that timelines past so all time stems from 1 absolute nexus point at the beginning of time stemming out into potentially endless possibilities

There's something to consider, though.
Before space rockets were even thought of, going to the moon was also -impossible-. Before automobiles were invented, traveling far distances was -impossible-. I could go on, but the point is that things that were once -impossible- became possible when we figured out solutions. How to travel long distances. How to go to the moon. How to do the -impossible-. It may be -impossible- to travel back in time now because no one has figured out a solution yet. But, perhaps, in the future, somebody might come up with a solution.
Food for thought.

The Novikov self-consistency principle doesn't really solve the bootstrap paradox though. In fact, the bootstrap paradox seems to hinge on the stable time loops that the Novikov principle is based on in the first place. There is no contradiction in someone performing actions that sets up their time travel trip in the first place but the point of the paradox is in how strange it is. It's just a brute fact that the works of Shakespeare exist, that one person would read it, and go back in time to give it to Shakespeare himself to copy. It's self-consistent, but weird.

before someone doesn't believe in my own words, time travel is really possible theoretically, the ones who says it's impossible is the ones that they keep watching too much movies which make them impossible, when there are ignorant science haters that says -it's not possible at all- then you guys are small mind and this and other videos are fake it will still remain an unanswered question instead of saying it's -impossible --- or just being really dumb and small minded, for the ones that are not smart and thinks it's only remaining in -science fiction movies-

everything in the universe is in motion. nothing is at rest. new elements are created by fusion. existing elements are changed by collisions or fission. objects in motion leave atoms behind and gain new ones. there are particles or forms of matter that we don't have the technology to observe yet, if ever. one second ago, everything in the universe was somewhere else in varying distances. the energy involved in all this motion and inertia would have to be reversed to put everything back some where in time and space.

if someone from the future went back in time to give the past something that would let the future exist then that wouldnt make any sense because the future never would have existed without itself existing which means for the future to exist then some random time in the future would have randomly existed for no reason and with no origin for itself to exist which does not make any sense and is impossible which means the movie Interstellar is impossible and does not make any sense at all but its just a movie so

The other problem with time travel is the spatial dilemma. The Earth is constantly in motion, so in order to travel through time and end up in the precise location on earth in the past, you would need to calculate very precisely where in the universe that point in time would have been. Even more difficult for future travel because it would be harder to predict events that might influence the movement of the earth, solar system, and galaxy through space.

It actually is possible it-s called negative energy which we can-t make now but black holes are negative energy. It definitely can happen one day if we stay around long enough and by the time we figure it out we should be advanced enough to know what and what not to do and it-s not a thing everyone could do it-s something that only nasa should do but still can be extremely dangerous one government could take over control of the entire earth.

There's also an issue with the law of conservation of matter. My body is made up of a bunch of atoms. Those atoms existed before I was born in other forms (in the food I would later eat, in the fertilizer that fertilized the food etc) So if I go back in time, this atoms now exist twice. Once in me and once in whatever they were in at that point in the past. A single atom can not exist in two different places at the same time.

If backward time travel existed somebody at some point would slip up and reveal it. But no one has. It might be a situation like dbz, where trunks entered a different timeline and his timeline had no changes. There could be infinite timelines since imagine you travel back 1 second but another time to travel back 10 seconds, it wouldn't quite be the same. Also this isn't even considering that it isn't currently possible.

If we travelled around earth at the speed of light for like 3 minutes then it wouldn't take us to the pas; It would take us to the future. Also time travelling with a black hole is impossible as a black Hole is actually a space body with infinite density. We see black holes as black because light can't escape from it (also it bends space and time around it. Thus they aren't actually holes LOL

Time travel to the past is impossible, because you'd have to rip a home in time/space which could destroy the universe, and/or destroy the traveler. You'd also be essentially reversing the forward progress of the entire universe which seems unlikely, as this would require an enormous amount of energy. Perhaps even a unlimited amount of energy.

There's no need to travel into the past, we are more than capable of changing the future today. It's the same as driving a car forward, you avoid obstacles before they happen you do not reverse back to tell yourself to avoid them. You cannot correct a mistake after the event only before with experience and wisdom.

travel back in time is impossible but travel to a parallel dimension is much more possible. you could travel to the parallel version of earth where time has been delayed and everything looks like 200 years ago but your not in our own dimension. it can look like the past even its a totally separate dimension.

To go back in time would be to reverse entropy. Which is problematic in itself. But not only would you have to reverse time on Earth you would have to reverse the positions of the stars. which means the entire universe would have to reverse. That would require an amount of energy unimaginable and unavailable.

Funniest and simplest problem with time travel:
You'd most likely just die in the attempt to do it.
Time travel, faster than light travel, shrinking ray, etc, would most likely be such a stress on the human body that, even if successful, would leave a corpse on the other side.

My biggest issue with time travel is the fact that the planet and the galaxy in the universe is constantly moving. So if one were to go back in time, wouldn't they just be in empty space because the planet, the universe and galaxy hasn't made it to that point in space, at that time?

I believe that IF time travel were possible into the past then those traveling would be nothing more than observers. Also the observers could not be heard nor seen. There eliminating any concern of such paradox's. And as far as traveling into the future that would NEVER happened.

the arrogance and folly to believe that a) its possible to currently pause 7. 8 Billion + Humans so that - YOU - can take a trip back in time, to somehow also, non-consensually just re-spawn all the happenings of the Earth and its inhabitants - back then - is just mind-boggling.

Or, alternatively, time will forever continue in an infinite loop, everything will always happen as it was meant to, forever. Any attempt to change it just ensures the events that took place originally will ultimately happen.

Time travel would be very possible to both past and present if only we could move at speeds faster than light and truly understand the math behind the fabric of space time. Scientists have already said it-s very possible we just aren-t there yet.

It-s not the paradox. The real question is Where is that past time gone? Everything has to be some where, right? So where is it? The real challenge of making time machine is that to access the time that has gone to somewhere unknown
