einstein's theory of relativity doesn't abide it, but instead suggests that going forward in time is possible... only if we can travel at the speed of light. i really wanna go back in time. man, i wish i had a doraemon ;((

It's only possible to look back in time, but it's indeed possible to travel forward in time, even below speed of light, just that lower speed has less effect.

aren't we traveling forward in time just by existing, since the time moves forward on its own? we travel from yesterday to today every day

@Kikugi It's implicitly about moving forward at an increased rate, otherwise it wouldn't qualify as time travel.

If it were the case, some people from the future would have already visited us, maybe? Or they h-hide among us!?

There is no need to speculate with non-professionals about a topic that you can learn more about from your favorite science journals and non-fiction books (I highly recommend everything written by Steven Hawking), but here is an uncommon point of view on time travel that I've never seen mentioned anywhere: time travel is possible, but we haven't met any time travelers in our time, because it is too expensive for them to travel into our era, and our current time is not important for them enough to go here.

I would rather go into an alternate universe that is 100% like our own and fuck their shit up instead of going back into the past of my universe and causing me to live in horrible bs.

I once took a short nap for what I thought was a full 24 hours because it felt like a lot of time went by and freaked out no one had woken me and confused how I had slept that long, then I realized even though it felt hours had passed I was only asleep a few minutes this caused me to feel a strange sensation as my brain tried to correct my mistake and it kind of felt like I had time travelled back a day.

It's definitely possible. Physics researchers have already sent photons back in time and I can see that being used to send information from the future and alter the past. How to actually send a whole object on the macro scale to the past is where it becomes more highly debatable.

lol uncanny this thread popped in my feed as I was just having a back and forth topic literally just now with Chat GPT

I want to say yes it's possible, however the concept of actually being in the past is basically impossible (most likely). The universe exist on principles of reality, and physics, once that is broken, the universe sets out to erase the anomaly, in order to revert it back to what is correct.

It's all a silly concept. Forward "time" travel is not at all what Relativity was really saying, it's basically that when you look at light, it's rays travelled toward you at the speed 186,000mps and that if you move matter faster than that somehow, you would technically have the atom arrive at a location before it was visible.
But reaching anything like that speed by being anything other than a beam of light... good luck

Yes, one look at history would tell you that time travelers are a thing that has existed since forever. Time itself is created by God to bind this realm, and he himself resides in a space outside of time.

I am not a scientific expert but based on the little I know about science, it isn't possible to go travel to the past in the conventional sense as it would break the laws of physics which we currently know and create paradoxes.

However, I believe (without proof) that one could travel in the past which would actually be a different timeline than the one where he/she exists presently. So, someone could travel to Edo period Japan but that would be a different one because of the time traveler's presence as an anomaly in that Edo period.

Then there's the "future" time travel hypotheses where a person experiences tome slower than the rest of the universe and thus is younger compared to the others who had become older and moved into the future. However, I don't consider this as time travel proper; rather its experiencing time slower than others and is a relative concept than the time travel hopping that we expect when we hear those two golden words.

yes, it is possible. if we can manifest tachyon particles(which is a hypothetical concept rn), by going faster than the speed of light in space time

I mean anything's possible, but that would probably create parallel universes.

A lot of quantum physicists think reality is the averaging of all possible universes, therefor all paradoxes must be resolved.

Basically, yes it's possible, but probably only in certain circumstances.

Going back in Time require exotic matter with negative energy, if you can mass produce in sufficient quantities, then you can go back in time.
we can mathematically describe scenarios where time travel could occur, but practical implementation is not possible..

I too want to go back in time

You travel back into the past and kill yourself when you were an infant. What happens to you? Do you disappear? because you could not possibly be an adult if you died as an infant. And if you disappeared how could you possibly travel back in time? This is one of many paradox. To explain the possibility of this occurrence there's the parallel universes theory. The moment you travel in time you just shift from your original universe to another.. which is kinda pointless to travel at all. You know there are infinite universes, universes in which everything is fantastic and you are happy and universes in which everything sucks, you didn't even born the earth has no life.. just stick in your universe instead of messing around.
The currently travel to the future is in fact not a travel at all, by traveling at the speed of light you are just slowing down your time you are not making it going forward.
What if the dark matter had already exhausted its strength and everything was rewinding? human experience would have no way of understanding it, you could be currently going from death to birth without realizing it.

You're referencing Einstein's special relativity. General relativity allows for the mathematical possibility of wormholes that let us go back in time. There is however no evidence wormholes actually exist, and without the existence of what is called exotic matter which we also have no reason to suspect exists or can be created in sufficient quantities to make a wormhole work, you could only traverse a wormhole if you moved at a speed faster than light, which is impossible. Basically, there are speculative reasons why time travel could be possible, but no evidence that it actually is.

Sadly as someone who likes some space sci-fi, this not being possible also precludes the possibility of intergalactic space travel.
