I have been pondering for quite a while, "what is time?" and I believe i have come to a reasonable outcome i believe.
At first it began with a wild fantasy about manipulating time. From that I questioned, "what is time?" and my outcome has turned out like this:
Time seems to be no more than human beings trying to add order to the world. Time is only a figment of our minds. We find things that are constant such as: the seasons or the sun rising and setting each day. Now time is an essential form of orginization but I believe it to be something else. I myself have defined time as the atomic motion of the world, where as every atom and particle is moving, making the standard view time seem completely wrong.
My outcome would also mean that to go back in time you would have to reverse all atomic motion in the universe.
I would like to know what your thoughts are about this.
traveling back in time by turning all atoms back in earlier positions but not you would give a problem: your atoms change all the time. so if you wouldn't change, there would be atoms missing somewhere, and there would be to many atoms somewhere else.
time is not absolute. though you can go to the front and to the back with one demension, you can move up, down, right and left with two demensions, and you can go up, down, right, left, to the front and to the left with three dimensions, you need the fourth demension to travel. if there is no time, nothing happens before or after something else. we need time. so time exists. that's one point.
you can travel to the future. if you just go fast enough, like, with almost the speed of light, you travel to the future. a twin brother that spends a few months in the ISS space station, is younger than his twin brother that stays on earth, assuming they are born at exactly the same time. if you have two clocks that are exactly the same, you send the one to the ISS for a while, and the other one stays here, you will see if the first one comes back, it's a little earlier on the space clock (but witch clock is showing the right time? well, that's another topic.) so traviling to the future is possible, only verry hard.
there is a theory that traveling back is also possible, but I am not able to explain that. it's about wormholes and a bended universe, but that's to hard for me to explain. if you want to know more about this: read 'a briefer history about time' from Stephen Hawking.
I think time exists, time traveling is possible, (we actually look back in time if we see the stars, for light has a travel time as well) and time is not made up or something like that.
I believe time is something that helps us be more organized before there was time, people would have to judge it by the sun.. How would you know when to go to school? Go to bed, it would all be a mere guess..
Time is a part of the measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify rates of change such as the motions of objects. Time has been a major subject of religion, philosophy, and science, but defining it in a non-controversial manner applicable to all fields of study has consistently eluded the greatest scholars.
I tend to view time as no more than a system of measurement. Time, as we use it, has utility in measuring the progression of events. We can say that event A occurred 2 hours prior to event B, but on any deeper level our concept of time really has no utility or meaning to us. For this same reason there was no time prior to events, and after all events cease there will again be no time.
