You keep using that word. I don't think it means what you think it means.
A car accelerates because it is forced to do so by the actions of my foot. Stop waffling, evasively, and tell these people why the whole universe - as they perceive it - will be distorted by their acceleration.
Is there a way one can waffle unevasivly?
The whole universe will appear to distort, kinda, when you accelerate in a car because the acceleration causes you to switch reference frames from inertial to non-inertial. A very simplified way of looking at it is that a little bit of the time axis of your local spacetime metric becomes a little bit of a space axis and a little bit of the space axis pointing along your direction of travel becomse a little bit of time axis.
Unfortunately, at the speeds and accelerations that a car can achieve relative to the Earth it is sitting on, the effects are negligable, so they haven't been incorporated into our collective "real world" experiences.
Are you implying that the body exerts a force upon the whole external universe, whereby that body's acceleration forces the universe to distort?
The body
does exert a force on the whole external universe. Newton came up with that one with his first formulation of gravitational theory way back in the 1700's. However, again, because we are so small compared to the objects around us, our personal effect on each object in the universe is negligable.
Further, the only net effect we have on the entire universe is a very, very tiny amount of gravitational pull, which is usually greatly overshadowed by other forces. I don't know if I'd call that a
distortion, per se, but it does have an effect. Acceleration only contributes to that gravitational effect through Relativistic mass increase.
Are you people so dumb that you believe anything upchurch says?
Are you taking stock of his responses to me?!
Hey, don't take my word for it. You can read (shock and horror!) about it for yourself. Here are a few links:
A favorite reference of mine
The best GR book ever (but very technical, which is why it is good)
Background on Newton's work
Googled GR
Or heck, we can ask one of the more active physicists on this board to come over and comment about the factual nature of my posts.
Sitting comfortably and smugly amongst your skeptical ivory-tower, feeling superior and right merely because the brainless masses are on your side. How feeble.
I thought this was a cute mixed-metaphore. Sitting in my ivory tower with the masses by my side. That's one
big ivory tower!
Go to a Christian chatroom my friend, and see exactly how feeble that answer is when used by individuals there to discount your skepticism.
I'd like to refer you to
this thread concerning true believers and those willing to look at all possibilities despite their personal belief. (You do realize that this is more or less a skeptic's board, right?)
