If an instant represents 0 passage of time or motion, then the present is as non-existent as the past or future. Since there is motion and passage of time, composed of instants, then I am constantly traveling into the future at a commonly shared rate.

I've heard of time dilation. I don't know if it counts as time travel. It's just the elapsed time between two events. Apparently you can travel at a speed fast enough to sort of slow down time for yourself while everything else seems to have sped up from your perspective. So if someone was to travel into space at an incredible speed (maybe something relatively close to the speed of light) you could travel for an hour and come back to Earth and maybe a month has passed. I think that's how it works, but if anyone else knows exactly how it works or if I got something wrong please correct me.

There are actually some theoretical models that should work to this effect, for time travel either to the past or to the future, that are significantly hampered by our current level of technology (and to be fair, possibly fundamentally flawed, reliant on theoretical or even hypothetical structures, processes, and phenomena that may not exist at all as anything beyond a misunderstanding of what we've observed, or are impossible for any number of reasons). One example of such is a Tipler Cylinder, which in practice would be reliant upon the use of 'negative energy,' which is only speculation thus far.

It should be noted though, that these models won't generally allow us to travel back in time to see the dinosaurs; the earliest point such a time machine could travel backwards to would be the point in time where it was first brought online; earlier than that and the structures used to manipulate space-time to facilitate the travel aren't there to make further travel possible. Similarly, the furthest point in the future that one could travel to with one of these machines would be the point in time where it was shut off or otherwise ceased working.

No man-made time machine is likely to facilitate a visitor in the modern day from the future, in other words. Of course, even this is not entirely impossible, as it is also possible that structures that facilitate time travel may be naturally existing in our universe, and would simply require finding and travelling to them to make use of them; these would have the same limitations I noted above, further exacerbated by travel time, but could potentially serve as gateways to the more distant past.

In short- I believe that time travel is possible, but that is not the same as stating that I believe that mankind will one day achieve it.

Well, actually, yes. I mean, not completely, as time travel to the past is literally not possible. To the future, however, it is possible. It isn't as much time travel, as going faster than whats around you, but it is somewhat possible.

there are some people who have survived the Bermuda triangle ...most of them say that they were in the past ..in the time of the french revolution or so ..so if they were able to go back in the past then ofcourse time travelling is possible

ya it be nice to go back and fix things that we did wrong

Yes I do, Our generation is just not that technologically advanced.

technically there are already a few ways to time travel by merely existing on this plane of time. you can slow down the rate of time you experience relative to others via time dilation via moving, essentially travelling forwards faster in time (observably occurs in satellites orbiting earth). however the question likely means backwards in time. in which case i don't think anyone can say for certain. i would like to believe anything is possible in the sense that what we experience is nothing compared to what is out there. there are likely innumerable 'senses' we might have developed to experience parts of the universe we currently might not know exists. or perhaps the mathematical tools of logic we developed only explains a small quantity of what is or maybe can not at all. the possibilities are infinite. the possibility of us knowing what we already know is only but one available. and science, although our currently most reliable option, is intrinsically fallible. or it could simply not be so. tough to say. impossible to know.

Maybe it is possible and we just don't have the tools. Like, cells exist, but back then they didn't know that and didn't think about it. They rejected the theory of Evolution. They didn't have enough tools, but it didn't mean that cells didn't exist. It didn't mean evolution isn't real.

The theory of relativity allows for a traveler to pass through time slower than the rest of us. Therefore I'd say yes. I'm not sure about backwards time travel though.
