it's important to remember that time is not a line, or many lines, but rather a dimension, just like space. Each point in space exists on its own, independent of every other point. The same is true for time; past and future don't exist, every moment in time exists on its own. There is only the present, even if you went to the "past" you would only be entering a different reality's present.

Neil Tyson stated that if we were ever able to make a time machine we would only be able to travel between the moment of the invention to any moment in the future. Basically saying the past is the past not even a time machine can change it

I have been stuck in time dilation from taking acid a few times. One time I was in the back seat of a car when the acid peaked, the song on the radio started to skip and the car I was in went back and forward in time about a thousand times and everyone in the car was skipping just like the record. We were driving on a bridge going about 50mph with cars all around us. Even the cars next to us were skipping and going back and forward in time. The scariest part was I was conscious the whole time wondering if I was stuck in time. Then the time dilation ended

Depends on whether or not you have a Mr. Fusion on board, doesn't it?

Can I get clarity on what kind of time dilation and perspective of the time dilation?

Traveling to the future is relatively easy, it's an engineering issue. All you have to do is either travel at close to the speed of light for a period of time, or just pass close to a black hole. If you do either of those time will pass much slower for you than for everyone else. In contrast there's no way within known physics to travel to the past.

Time dilation would mean strecthing time and thus, to a normal person's perspective, everything around him, would be slowing down at an exponential rate, and unless he has some sort of protection against physical laws trying to make him obey them, he would most likely die in less than 5 seconds. Another point would be that since you are strecthing time, you are and are not really moving to future in a per-say manner, hence the location, although in a future time, would be unknown.

Well like the whole time in space vs time on earth delay it is technically neither past or future for either parties. But logically speaking time is not stored like an ssd game save so I would say future is the more appropriate term to say.

From what I understand according to special relativity's time dilation, a spacecraft accelerating up to the speed of light, time for the occupants slows down till the craft's acceleration reached the speed of light. Then time would be zero traveling at c. Time would seem to freeze for the occupants while the craft continued to travel at c. To the occupants they could travel the entire length of the universe in an instant because time would be zero while the craft was traveling at c. Hence the reason for quantum entanglement. The craft could make a loop and go back to the point where they started and seem to have experienced no time at all returning to the same point in time when they left because time was zero. The occupants and the universe around them would not have experienced any time passing. They would not travel in the future or the past. Accelerating the craft to twice the speed of light time would appear to reverse at a rate of -1 for the universe around them while the occupants were frozen in time till they returned. They could start off at noon and return at a different point in the past in an instant. So time travel through acceleration only takes the occupants to the past. Traveling to the future has no mathematical solution as far as I know because there is no such thing as a negative velocity. You can put your craft in reverse but it would still just be accelerating in a different direction in space. The only forward traveling in time happens when you're near a rest, standing still relative to the motion of the Earth. Time then passes at a rate of 1. In reality there is no way to accelerate a spacecraft up to the speed of light because of the energy requirements in the equation. It requires an infinite amount of energy² to be applied to the EM fields around the craft. That's impossible.

If you're observing a dilation and you travel into it then surely you're travelling into the past, right? (Genuine question, I'm a physics novice.)

Einstein, has to be travelling to the future, the faster you go the slower time goes for you and this means you travel faster than the second per second we normally progress into the future at.

We are travelling into the future differently to other people all the time just by moving relative to them. Light travels at the same speed for all observers moving relative to each other, no matter of their relative speeds. Therefore it has been verified by countless experiments and observations that it is space and time that squeeze and warp to compensate for the constant speed of light.

The correct answer is “unknown” as humans have never tested this hypothesis/theory. Until tested it is not known as scientific fact.
