How could Time Travel even theoretically exist?
I'd like to hear some theories on how time travel would work, or why it is impossible. I, for one, do not think it is possible, since time does not actually exist, and it is impossible to pass through something that does not exist. I'd be glad to hear your guys' thoughts though.
Edit: Elaboration on time not existing: Time is an abstract concept used to explain reality. Creds to ViperVenom1224 for compacting my unorganized rambling into that one sentence.

Time is an illusion. It's only a tool to organize our senses and perception of the world around us.

We are constantly time travelling... Forwards. At a constant rate. This can almost certainly be manipulated because of two things: You cannot have a time without a place or a place without time. This is why space-time is a big thing in physics they're almost the same. We are always moving forwards, moving backwards or changing the speed is the idea of time travel. It's even been postulated that the axis in the 4th dimension is time (but we can't willingly transverse it). If you can warp space (see black holes) and space exists in the state of space-time then we can warp time (see black holes) and therefore time travel.

forwards easily. backwards not so much

Well, live around blackhole for year. 10000 years will be passed at the Earth.

If an astronaut travels away from earth at 0.999% the, speed of light for one year, then turns around and returns at the same speed, two years would have passed for the astronaut. However, everyone else on earth would have experienced a dozen years or more. Theoretically, anything approaching the speed of light, or any object of sufficiently high gravity such as a black hole, alters the rate at which time passes for anyone caught within the effect. However, according to those same principles, it is only possible to travel forward in time, not backward.

Edited by sigma: 7/6/2016 12:42:19 PMI'm going to explain that like this: Theoratically if Time Travel would exist we wouldn't exist overall. People would mess with Time itself. If we still exist, then there has to be a Multiverse where our other Doppelgängers from the different Timelines live. Even forward wouldn't work because the future is in a unlimited motion never stopping. If i would travel one day forward i would know what happens, preventing that from happening that future never existed, or at least in a Multiverse, causing the fact i couldn't travel to that moment because it never existed.

Wormholes or Einstein-Rosen Bridges, are considered to have the most potential for time travel if they do exist. Not only could they allow us to travel through time, they could allow us to travel many light-years from Earth in only a fraction of the amount of time that it would take us with conventional space travel methods. Wormholes are considered possible based on Einstein's theory of relativity, which states that any mass curves spacetime. To understand this curvature, think about two people holding a bed sheet up and stretching that sheet tight. If one person were to place a baseball on the bed sheet, the weight of the baseball would roll to the middle of the sheet and cause the sheet to curve at that point. Now, if a marble were placed on the edge of the same bed sheet it would travel toward the baseball because of the curve.

"Most people assume that time is a strict progression of cause to effect but actually, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly wobbly... timey wimey... stuff."

Forward, possibly. Backward, not really.

4 RepliesWell i hope it isnt possible. Who knows what people will do. It would probably result in a lot of death and us breaking the universe. So its best not to time travel.

1 ReplyEdited by Necrobump Ninja: 7/6/2016 3:06:25 AMTime is actually really really confusing It doesn't exactly go in a straight line but it's more like a spiral and some parts of the spiral connect and events are like dots that take up certain parts of the spiral... Idk exactly. It would be easier to draw a picture for you. All I know is that it disapproves a lot of other things that are believed by a lot of people because most people base their opinions off of time being straight. Edit: here, I tried drawing a picture of it http://imgur.com/RGKeDtg The black line is the ideal time. It is the time that we experience. It goes in one endless line. The red lines are overlaps between specific parts of time. A lot of people believe that blackholes are examples of this. For example: if one were to fall into a black hole they would end up billions of years in the future/past. The green dots are events. In each green dot an event occurred. They can occasionally overlap with other segments of time however that is rare. I misdrew this and drew all of them overlapping however I should of only drawn a few of them to overlap Another thing that a lot of people believe is that time isn't figurative but it is an actual object. If the universe is a cardboard box time is like wrapping paper.

1 ReplyThe true question is: What if the future got so bad because we learned how to travel time and screwed a lot of things up, so we went back in time to stop ourselves from learning how to travel time, yet it only gave us the idea of traveling time?

1 ReplyI'll use Terminator as an example here. They go back in time to stop the murder of John Connor. This makes no sense, because if John Connor is still alive, no matter the outcome, because he is still alive after they save him anyways.

Time is an illusion, an illusion isn't real. Therefore time travel isn't real

It is possible at the sub-atomic level. http://www.collective-evolution.com/2015/12/07/physicists-send-particles-of-light-into-the-past-proving-time-travel-is-possible/

If someone in the year 3000 invented a time machine, we would've heard about it by now.

Quantum travel would indicate that all points in "time" exist in the same space in the universe, and it is theoretically possible to travel to any point in time it space. There is no guarantee that you could arrive in the same place and time ever again, however. This has been theorized in many books, films, and TV shows. Michael Crichton wrote a great book that handled the subject well - Timeline. The movie, while entertaining, did not. There's also Quantum Leap and Sliders, both deal with the subject matter in interesting ways, but keep the fundamentals intact.

We are amidst strange beings, in a strange land. The flow of time itself is convoluted; with heroes centuries old phasing in and out. The very fabric wavers, and relations shift and obscure. There's no telling how much longer your world and mine will remain in contact.

You would have someone create a paradox, then walk through the time rip

With enough psychotropic compounds in your system you can definitely time travel.

Backwards time travel, As far as we know, Is impossible. Forwards time travel is actually very simple. You can either travel very fast (1% under the speed of light) or you can orbit around a supermassive black hole. In going fast, Spacetime distorts to make sure you never go over the speed of light, and therefore time slows down inside the vehicle, whilst it continues normally for everyone else. In orbiting a black hole, the immense gravity warps Spacetime for you, slowing down time for you. So yeah.
