Ok, so now, I will explain to you my theory of time travel. It isn't really a theory, though, because it is all
true. Once I thought of this, it changed the way I think about the way that the universe works. I hope it can do the same for you.
Time travel is the idea of moving an object or person backwards or forwards in time. It is impossible. This is because time is a concept developed by man. Time is basically a measure of the duration at which matter continues to exist. As any matter is now existing, the time it has existed has increased. To help explain this point, look at the following example.
Time relative to matter:
Tree Tree (Now)
----------------------------------------
----------->
Time
As the tree continues to exist, as does time. Now, to travel back in time, would be to travel back to when the tree was in its first instance, or in other words, when the tree had existed for a lesser amount of time. So, time travel is impossible because time, which is represented by the arrow, is a concept and is not tangible. So, time travel is now conceivably possible. But, if you cannot change time, maybe there is something else you can change?
The only other thing to change s the tree (matter), so we cannot time travel, but the closest thing to it which is conceivably possible is to change all matter in the universe to a point where has the same properties that it had at a point in the history of time, except the person who is traveling in time. Also, this person would need to go to the person who is about to time travel again, and tell them not to, because otherwise the universe will be set on an infinite loop. Some people may say that this would mean that the whole incident never happened, but it actually did, but now it is happening again, but the person is changing the sequence of events.
I hope you have enjoyed my theory on time travel, please post comments, or add to this if you have any other interesting ideas. Thank you for reading.
