Now I could be mean and simply say that you are traveling through time right now, just at was is considered the "normal pace." However, that is boring. The time travel that I will refer to is the concept of traveling back and forward in time.
Lesson 1: Time is relative, it speeds up, slows down, all based on how an entity perceives it. Time can be going by fast for you but slow for another. If you want more information look for Einstein's Theory of Relativity.
Lesson 2: Relative time comes in 2 forms. The first form refers to the manipulation of the "fabric of space-time." For organization purpose I will call this form "Gravitational Form." The second form covers time travel when you do not manipulate the "fabric of space-time" instead you alter another property. I will call this "Relative Form."
Currently both forms of time travel exist in our universe. The easiest to explain being "Gravitational Form." By now most of know about the fact that gravity will alter your perception of time. The more gravity there is, the more the "fabric of space-time" is warped causing time to slow down in that area of space. Time on Jupiter is slower than time here. This form is relatively simple, while this may not be considered time travel that people want, it's a way to travel forward in time. If you place yourself inside a large source of gravity, you could suspend yourself so that no time goes by for you while hundreds of years pass for others. The only problem with this is the fact that you would need to be able to stay alive inside this source of gravity.
The second form takes on different types and is completely based on relativity without gravity. The first and most famous form of time travel with this method is the concept of cryogenic stasis. In this form you also travel forward in time. Your bodily existence is slowed while frozen and when you unfreeze, you end up later in time and can return to living in a body. This form of time travel also allows you to travel forward in time.
So far both these are valid methods for traveling through time, however traveling back in time is territory that has not been stepped on yet. If take one theory for time travel, we can break it down and try to figure out how it works. If we take it from Doctor Who where, “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... time-y wimey... stuff.” As absurd sounding as it is, it's a valid theory that has been supported. In our current time frame we view time as linear, where there is the past, present, and future existing at the same time. This is where Doctor Who fails to abide strictly by these rules. If this state of time exists, that means that time is solid and unwavering, no matter what you do, everything is predetermined. If this theory works, time travel will work but you won't be able to effect anything. If you imagine time to be a sphere, the present is a point inside the sphere, and the point is constantly moving. That is how the perception of time works, however, all of time exists together as an entity with no end and no beginning. Therefore your perception isn't actually moving, it's staying still, as you progress through time to the future, you are moving from point to point, the point is not moving along with you. It only seems that the point is moving because we as humans can only perceive the present and the present is constantly changing. Another way that this theory would work with time travel would be if there were multiple balls of time-y wimey stuff. That would mean that perception can only move from point to point "forward" while attempting to move backward would put you into another sphere elsewhere. That would mean that you being back in time was already preset in that sphere. Once you finish messing up the past in that sphere you would jump to the future and claim that you change time. The problem is that moving forward in time will not bring you to your original sphere, it will bring you to a later point in the sphere you are currently in. In the perspective of the time traveler, he/she remembers the old sphere as the original time frame, now that a new time-frame and he realizes it's different, he/she will claim that he/she has altered time. In reality he/she has only jumped bubbles.
If we take this example of how time works, lets figure out how to travel back and forth in time. Traveling forward in time doesn't appear to be a problem. The act of traveling forward in time is the act of moving the consciousness of the person to another point that is "apparently linear" in progression. In the physical world it would appear that the person is frozen in time only to be released later. If this is the case, time travel forward in time would require a physical space to be available in both the release time and the end time. While the space is not required in between these two times, it's much safer to have it since recreating the space would be much more of a hassle than maintaining the space.
Now we can tackle the concept of going back in time. In every science fiction film the process of going back in time would require a machine of sorts. It's safe to assume that a physical entity will be required at the start of the "jump" and will be needed at the destination. While the start and the end are in different spheres, the physical transport is still required. Although this process would probably take a lot of energy. Because of this massive requirement of energy, we have not been able to create methods to get back in time.
If all of this is true there are a couple of laws for time travel under this theory
1. Traveling forward in time requires a physical space and low energy.
2. Traveling back in time requires a physical capsule and high energy.
3. Traveling forward in time will keep you in the same bubble.
4. Traveling back in time will move you to a different bubble.
5. The bubbles are made with an "apparently linear" form.
6. Bubbles are not changeable.
Note: This is a theory. It probably has a lot of holes considering I made it up just now.
So, in essence, the bubble theory represents alternate universes. So what I think you're saying is that if, say, I went back in time to kill Stalin or Hitler, I would create a new bubble and remain in that bubble when I returned to the present. Or you could be saying that the bubble already exists, based on the alternate universe theory, and that I'm traveling to that bubble where Stalin was killed...but I'm almost sure you mean one of the two.
ReplyDeleteEither of those theories could be correct or both. The power required to go back into the past is the power to move to another bubble, either that or the power to create a new bubble. However, logically the power required to create a bubble would be much more than entering a bubble that already exists. Therefore, the safe bet is that there are an infinite number of bubbles in existence and we can enter them via time travel, and that creation of a bubble is impossible. Or there is a limited amount of bubbles and based on the types of events we are changing, it could be either creating a bubble or entering another one. If this is the case, then it would mean that traveling into the past would require different amounts of energy for each trip.
