https://en.wikipedia.org/wiki/Time_travelSome theories, most notably special and general relativity, suggest that suitable geometries of spacetime or specific types of motion in space might allow time travel into the past and future if these geometries or motions were possible.
In the simplest sense, could time be space? — TheMadFool
I would say no because then we can assume "non movement" trough space as stopping (or slowing down) the time which isn't the cause.
A question may arise, what about inanimate nature? it is subject to time as well. — SpaceDweller
"this is the right distance for a killshot?" — TheMadFool
So then if we took a "snapshot" of this very moment with it's totality, that being: — unintelligiblekai
Yes that is correct form of "time" traveling, it's just hollywood concept for people to imagine itwould that not be considered time travel? — unintelligiblekai
would that not be considered time travel? — unintelligiblekai
It still wouldn't be time travel. It would be recreating the past in the future. Just like recreating a natural diamond perfectly in a lab, doesn't make another natural diamond, rather it is a natural appearing lab grown diamond. — LuckyR
Time travel is the hypothetical activity of traveling into the past or future. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a hypothetical device known as a time machine.
Impossibility of time travel seems to be one of the universally necessary truth. — Corvus
If one believed in the multiverse which runs on different times, would it be then imaginable in one them? — Corvus
But multiverse itself is a theoretical hypothetical idea, which is not proven to be existence yet. — Corvus
What makes it impossible? I take it your view is based on the immutability of a single timeline — Luke
Why would you assume that? — flannel jesus
Why would you assume that? That's very abstract. How about something more simple: it's impossible, as far as we can tell, because there's no known physical phenomena that could allow us to do it. — flannel jesus
It seems the whole imagination has been based on the wrong assumption that the past and future are some sort of geographical destinations such as Tokyo, NY, Paris ... etc, which is not.Let's suppose I build a time machine and use it to travel to a time before my birth. What makes it impossible? I take it your view is based on the immutability of a single timeline, but that's never been proven and I can find no good reason why it must be assumed. — Luke
It has been imagined in numerous works of fiction, so it does not appear to be unimaginable. — Luke
Sure one can imagine anything, but we are just letting them be aware that it is imaginable (at stretch), but impossible in reality from the logical and metaphysical point of view. :)The question of the OP is whether time travel is hypothetically possible. I don't see why not. — Luke
It seems the whole imagination has been based on the wrong assumption that the past and future are some sort of geographical destinations such as Tokyo, NY, Paris ... etc, which is not.
Another wrong assumption is that time is some type of physical distance laid out like a road or highway.
The reality is that time is an illusion, and there are only Durations (already proved and declared by Newton), and the past and future are concepts, not geographical places you can arrive at or depart from. — Corvus
You cannot travel into a place where the destination doesn't exist. We are all nailed into the present until deaths under the universal law. — Corvus
Can you travel into your happiness or hopes? There is no such a place as the past or future. There are geographical places such as the countries, cities and towns, not the past or future. You cannot escape the present. It is a universal law, which the whole universe and its contents must abide by.What makes these assumptions wrong? What argument supports your assertion that times are not "geographical places you can arrive at or depart from"? — Luke
And you will be waking up from your dream or imagination. :DWhatever time I am at is the present time for me. Therefore, if I were to build a time machine and use it to travel back 100 years, then it would be the present time for me when I depart today and still the present time for me when I arrive 100 years ago. — Luke
