Furthermore, even if this is off topic. Mathematically, the more you approach the speed of light, the more time speeds up around you (but not for you). This is all theory and not fact but it cannot be proven wrong with modern science either. Science fiction may have used the theory and twisted it but there is a basis for it.
I was mostly skipping around in reading. And I didn't say it was wrong because I didn't want to waste time explaining the mathmatics and experiments, its that I didn't have time.
Mathematically, the more you approach the speed of light, the more time speeds up around you (but not for you).
Actually no, this is not the theory, this is the limited understanding of the theory which you possess. And I will explain below the problem with it. Basically you have it backwards. First, you do not approach the speed of light, the universe around you does (I explain this first). Second time does not speed up for things outside of your space ship, it slows down (I explain this a bit later).
Yes, theories can be disproven. But unless you are prepared to disprove this theory, which I doubt you are, then there is no point in you mentioning this fact.
The basis is very slim.
The first concept you will want to have to help you understand (this is what my reply would have been if I had time, so Im remedying it right now, hope you accep tthis apology) is that there is such a thing as "inertial frames of reference".
Two people moving at the same speed are in one inertial frame of reference, another person moving 50 mph faster are in another inertial frame of reference.
The first rule is that there is no physical reason to prefer one frame of reference to another. You will mathmatically prefer one frame of reference depending on the problem at hand.
Now then, there is an equation that defines the time dilation effect. In the equation the variables are this "time", "Proper time", "velocity".
Think of each variable like a knob on a machine, by changing one or two you can effect the outcome.
Proper time is the time taken from an observer that is not in motion. The problem is that any observer can be the proper observer. If a person is moving at a constant rate, relative to them, they aren't the ones moving but the universe around them is.
Think about it and it makes sense. You see, you think you are stationary right now as your reading this. But in reality, if I had a video camera somewhere in the solar system that wasn't moving then it would look like you were flying around the sun, very much in motion.
So the question is, if one person is moving in reference to the other person, and the other person is moving relative to the first, then who is right?
Simple, both of them are right and both are wrong. That means you decide which observer is the proper observer for an arbitrary reason.
Here are two more rules for special relativity that for now I want you to assume as fact, yes I can derive them, but its time consuming and hard to write here. But trust me, the two of them are right:
A ruler in motion is smaller then a ruler at rest.
A clock in motion runs slower then a clock at rest.
The thing is that the way they use it in scifi is basically a twisted and perverted version.
They basically state that there is an inertial frame of reference that is preferred and one that isnt. They state that the inertial frame of reference of the planet is preferred to the one of the space ship. This breaks the fundamental rules of relativity.
So basically, they are saying that the universe does not move relative to the person in the space ship, but the person in the space ship is moving even from within his own frame of reference.
And here's one last little tidbit, food for thought. The guys that write these books are english majors, they don't study advanced physics. I am studying to become an aerospace engineer, so I do have to learn and understand this stuff as part of my course load.
Understanding of physics:
Physics majors > Scientists and chemists > Engineer majors > Doctors and surgeons > inanimate objects > English majors.Edited by Singular1ty - 4/13/11 at 11:54am
