There's a huge difference between space & time and spacetime. Space and time, taken separately, are relative. Spacetime, however, is absolute in some sense. The Minkowsian norm of the spacetime interval, for example, is invariant for all observers.
Do you have any idea what this actually means within the context of the universe itself, or how this information relates to that universe, or are you just parroting knowledge passed onto you from another source?
The point of this thread and my mentioning of Einstein is to explain how theories are moulded around the idea that the universe is real in itself.
Until such time as you may be able to get this into your skull, then I'm afraid that anything you say about it will come out as mush.
Really?
Do you now comprehend that scientists are studying the order inherent within the
experience of the universe yielded via the sensations? This is an undeniable fact, since humanity cannot study anything other than it's own experience. All I want to know is whether you understand it?
If not, then it's upto you to take a time-out and contemplate what I mean.
But, if so, then what you're saying is completely irrelevant, because the fact is that we all experience the universe with parameters - the values of which are relatively different for each individual. Hence there is no absolute space or absolute time.
Now, you are saying that there is absolute spacetime. So, since you think that I don't know what I'm talking about and that you obviously do, I hereby challenge you to explain what, in itself, absolute spacetime is within the context of the
experience of this world which we are having.
Two observers have absolutely identical models of spacetime. The whole point of Einsteinian relativity is to have a consistent model of physics. I don't know what you mean by "experience," but the experiences are no different from seeing the Brandenberg gate from the back versus the front.
I'm not for a minute suggesting that there isn't
Something absolute or singular upon/within which all of this relativity-experience occurs, but to describe that thing as absolute-spacetime is pathetic.
Wrong again. You do this a lot. Light per se isn't special. c is special. It is the constant that relates time to space the same way the constant 1 relates kilometers north/south to kilometers east/west.
I'm sorry mate, but if you don't see anything special about an energy that will always be perceived to move at the same velocity regardless of your own velocity, then you haven't given it much thought.
For example, let's swap 'light' for 'cats'. Imagine that the velocity of all things in the universe, including light, was relative to your own motion. Except cats. Cats would always be perceived to be moving at 20m/s regardless of your own velocity. So, any intelligent person would regard the motion of cats as "special" with comparison to everything else. But not you, apparently, since you see no big deal about an energy that apparently disregards your own motion!
Think man, think. And think within the context of 'light' being a sensation, rather than a real energy existing outside of yourself and moving through real space & time.
As I said earlier, science studies the order inherent within the exerience of the world, yielded by sensations. And 'light' is a sensation. And the reason why there is a constant relationship between the observing mind and the sensation of light, is because light is not an object in a real world... and neither is the observing mind.
Light simply happens to go at c because it can't go at any other speed.
Oh, so light doesn't have any "special" properties? Then perhaps you could explain to this forum why it ALONE moves through the same [supposedly] real universe as every-thing else, but, unlike everything else, it's velocity is not perceived relative to your own.
Climb the ladder mate. This isn't a test about who knows more about physic's terminology regarding any specific theory. This thread is a wake-up-call, asking you to see beyond all of that and ask questions. The pertinant question is: does this terminology have direct relevance to the reality of our world? And you cannot truthfully answer that question until you understand that the "reality of our world" is a Self-generated experience, composed of ordered sensations.
