Studiot, I think I see your point. So it is not very proper to discuss the essence of spacetime using incomplete language. ErikD, thank you I'll definitely find this film.

Thanx, adaptation. I've just read wikipedia article about space and it says: "Space is one of the few fundamental quantities in physics, meaning that it cannot be defined via other quantities because nothing more fundamental is known at the present.". Does this mean that there is no actual...

Vanadium 50, I don't remember saying anything about voltmeter directly measuring voltage, but whatever. The wrong with the ruler is the same as with watches. There is no special space-force that helps to move the ruler. The ruler moves through space. For comparison, magnetic field does help...

Thanx, adaptation. Your phrase "Energy moves the arrows over time" made me thinking about space coordinates. Basically we do not measure x,y,z coordinates either, we just move through them and that's how we can tell about them. So there is no proper (aka voltmeter for voltage) measuring device...

Ok, I have read through this forum posts about 'time'. And have another stupid question, this time about clock. Apparently we measure time with clock. The clock has arrows in it just like in any other measuring device. So we can talk about time changing by looking at indications of that...

Thank you, DaleSpam. Your explanations regarding derivatives were very helpful. Now I understand why there is a need for such thing as 'time' to describe different processes. Ok, now my mind is a little bit more clear. I think I got to check out those links by Tomsk now. If I'll have any...

I don't push anything you just misinterpret my words. Actually Tomsk gave all answers I needed. Somehow he understood what I was asking. So your accusations are irrelevant.

Thank you very much, Tomsk. I have suspected that there is something wrong with 'time' in physics. Now I see that it is simply an open question and has no concrete answer yet. I'll definitely check out those essays. Thanks again, your post was very helpful. I suggest if anyone finds interesting...

adaptation, thank you for your explanation. But than I have another question. Does time actually exist? Or is it just how we perceive things? Is there a 'time' without us? Had any scientist answered such questions?

DaleSpam, yes I understand derivatives and I know that v=ds/dt. But my explanation was descriptive not formal. To make it clear can anyone answer this questions: 1. Is there some experimental data that proves that time is actually another dimension? Or maybe theoretical explanation? 2. Had...

And I'm hoping there is someone out there who is as confused as I am so he can contribute to my questions...

Ok you made me thinking. We define speed through distance and time. That's odd. But what the time is anyway? I though of it as changings in a matter. So there is no 'time' at all. But FizixFreak says that time exists even if matter is not moving. So it's kind of 4-th dimension. But is there any...

Chronos, why there is a need of such thing as time to keep everything from happening at once? Isn't it sufficient that there is matter (atoms and stuff) that moves at different speed thus creating different states one after another. Because speed is fixed (not infinite), there is no possible way...

FizixFreak, yes that's exactly what I'm talking about. I know this point of view. But I don't understand it at all. What is the base for such assumptions? Why one thinks that time exists without movement? Is there some experimental data that proves that time is actually another dimension? Or...

I don't know if I can say it right. One says that time slows down when an object's velocity is approaching a speed of light. And I don't understand why we are talking about 'time'? Why not particles start to move slowly and because of that we perceive time differently. But my main point is why...
