I keep thinking about time. What it is, and how can it vary.
I have no way of proving anything I am about to discuss…So hopefully you can put up with a layman musing about things he probably has no real handle on.
I will and always contend that from the moment a segment of time exists till now, it is all one piece. In other words, time begins, flows, and eventually ends. Time never stopped. It doesn’t break. Time at the end of time is the ending of the same motion to the future that started at the beginning of time. If you’ve ever played the game Pipeline..think of it as a never ending (from our perception) game of Pipeline.
Why is this important? Because the more I think about, the more I feel that NOTHING happens without time. Furthermore, nothing is faster than time.
Now I’m not talking about our perception of time. I am talking about any opportunity for anything in the entire universe to happen or exist, or age at all has to be accompanied by time. Without time, there is no movement, and nothing would be able to perceive dimensions, because nothing could think or perceive without time to give it the opportunity to do so. In essence, if all the matter in the universe existed, it would be a moot point if time didn’t let it do something from one moment to the next…and therefor, even if matter there fills the space that we consider three dimensions that we know as the universe.. without time, the universe more or less doesn’t exist.
My question to you about relativity is this.. should we be concerned with motion, gravity or matter being relative to time? Or being relative to ALL of time? I ask because it seems to me that a lot of realtive is about figuring out the relation and progress of motion, matter, force, energy, gravity against existing moments of time. But we start those existing moments from the moment we’ve reached our desired set of circumstances/speed. What if time really has to be measured into relativity as a whole to be accurate? I know we don’t know the absolute true moment time began. But imagine for a moment, that time begins at 0 and it currently at 1,000,000. Now lets say that you were able to take a trip that takes 100,000 years. At the end of the trip you would have traveled for 200,000 years. When you get back, is your segment of time at the beginning of your journey 200,000 years old? or 1,200,000 years old? When you left, you were at current time, which is 100% of existance of time at that moment. When you get back you will ALSO be at 100% of time at that moment. However, all the matter of your ship and its contents at that time should be aged less of the current amount of time. Why? Because for every moment of time that passed as you were traveling, you were traveling a finite distance and coming back, but time kept ticking on infinitely and as time became more and more, each moment of time became relatively smaller and smaller as a per centage of the original plus the new time added on.
OK..my analog.. Imagine walking next to someone who is 80. And you are 30. Walk with him a year, and he will be 81, and you will be 31. He got 1/80th older, you got 1/30th older.. But you both walked the same amount of time. Walk another year, and he gets 1/81 older, you get 1/31 older. Another year and respectively, 1/42 older, and 1/16th older. two years later you’ll both be 1/43 and 1/17 older. Matter is probably much younger than time, so matter will always mature a little faster than time at this point, because time will always be a much bigger age.
Following that logic,
the universe is estimated to be roughly 14 billion years old (according to wikipedia) and a brand new ship goes on a 10 year each way round trip:
So the universe will be (1/11 billion years) older by the time the ship gets back, but the ship will only be 20 years old. The universe will be 14.00000000009090909090909 billion years old. More specifically, the spot that the ship returns to will be that old. Now think of that as one long sheet. Now, visually imagine being able to see that sheet with a box representing the age of your ship on top of it. Now imagine that the box got 20x bigger, but at the same time that sheet got 1/11 billion year bigger. Even though the box expanded, it would look relatively smaller than its previous size in comparison to time. Now consider that the mass of the object actually gets smaller, and it would look even smaller in age compared to the rest of the age of the universe or time. In other words, the object gets younger. Or more, at least, it gets relatively younger in age compared to the universe it just traveled in, because the amount of time the universe aged, grew at a faster rate than the ship could travel.
