If time travel is theoretically possible, then every thing that will happen has already happened. Right?

Answer 1

Exactly! And not many people can make that mental leap.

If time travel is possible then we are a part of one infinite now that we only appear to move through. Perhaps so our minds can better deal with choice. It's very Taoist.

And one of my favorite pet theories, by the by.

Answer 2

this is based that time is liner. Based on that assumption we must first determine where we are on that line. Most likely we are somewhere in the middle, meaning that all our actions (such as me answering this question) has already happened and i am just following a predetermined path. Just like a movie, the people in the movie can only do what they did in the movie while it was recorded and nothing more.

However time can be viewed as a web of intertwined lines. Each line is a possible reality and we can cross over into each of these lines and therefore create a "new" reality, however the reality is still based upon a set of already established lines, Kind of like a video game - you can move around based on your needs but only within the confines of the programming or lines.

but as was pointed out it is not theoretically possible, but assuming that it was then you perspective would depend on your concept of time.

Keep expanding your mind, never mind what people believe that is possible and what is not. At one time science believed that you could not sail around the world without falling off the end, and once it was believed that sound was the fastest you could go, our understanding of the universe is based upon our own knowledge and assumptions so if the fundamentals are wrong everything you build upon these is wrong. In a few hundred years we will think that we are superstition and guided by beliefs and not science.

Answer 3

All of time and space can be modelled in what as known as "The Bulk", where all spatial & time dimensions map out a geometric space. Looking at this, it would appear that the future is already there in the distance, just as a gas station is already there 20 km away. The thing is, we can't access our future.

To clarify, special relativity predicts that by doing some tricks (travel at high relative velocities, go near massive objects) we can make time flow slower for ourselves than for others. Thus we have gone into someone else's future, but we always live in our present. So, to ask if everything that will happen has already happened is kind of meaningless, since we can't ever 'see' our future.

Now, if you want to get pseudo-scientific, if there was a being that could 'see' the time dimension as we 'see' three spatial dimensions, then they would say that yes, everything that has happened Has indeed happened. I'm sure they would be very interesting to meet at a cocktail party.

Answer 4

Wrong, eventually everyone I know will die. They aren't dead now, therefore all that will happen has not happened yet. This doesn't prove or disprove the theoretical possibilities of time travel, but it does present a problem with your statement.

You could just as well ask: If cartoons could come to life, could I make a cartoon of myself and change my life?

Answer 5

Well, your question seems to assume that we travel forward in time I guess? Time travel would hopefully be possible both ways. But anyways, lets assume that you left the now and moved a month forward in time instantaneously - you would have been gone a month and thus not done what you normally would have done during that month. So - no.

Answer 6

According to the string theory of time, there are an infinite number of possible futures.

Answer 7

I try to leap, but never get off the ground! But I do enjoy reading & listening to what other people have to say on the subject!!

Answer 8

Now you're in to Heisenberg. By going in to the future and observing an event, you could change it.

Answer 9

Time travel is not theratically possible.

Answer 10

um, something like that...watch the x-files reruns for all of the answers!
