What is time?...your own definition...or what you know...

Question

Well...one of my friends did a poem about time...and it said something like there is time for everything...but really, what is time? is it just something we made up...does it have anything to do with entropy...

also...the formula speed=dist./time...would mean that time is dist./speed...so if you have no distance and no speed you would have

no time...plus you can't divide by zero...

and another thing...what does time have to do with relativity...if anything...

thanks..

Answer 1

Time can be extremely useful in life and physics, as in measuring rates, or describing space. It can be described as a measuring system to determine the sequence of events.

Relativity established time as a dimension in which things move.

Answer 2

time, as described by quantum and relative mechanics, is a force. It is said to be interwoven between space. As for the formula what you said is invalid becuase the formula is set up so that the values must be present. As far as relativity, time can be affected by the presence of matter. The matter is said to warp the "fabric" of space time, which contains time. This is just a simple explanation of a problem that has plagued physicists for centuries. I would recommend further reading.

I have wondered the same question. I got some books, read them, and now I have a clearer understanding of this.

Answer 3

This question requires some serious thought to respond to. Is it just something we made up? I believe it is. Your second paragraph is pure logic. Time and relativity. I think Einstein goofed with time dilation, I am convinced that the only thing that dilates at near light speed is, motion, not the forward motion of the moving object, but the motion of the particles within the object. We know that at such speed an object gains mass and shrinks in the direction of motion, the increase in mass reduces the space available for motion and at the same time increases the inertia of the particles. If you subject a clock to such a speed, the mass of the moving parts increases, but the energy supply does not, the parts will move more slowly because of this, the clock will show time lost, in fact, the only thing that has happened is the reduced motion of the parts.  

Answer 4

The definition of 1 second is the time it takes light to travel one 299,792,458th of a meter since the speed of light is 299,792,458 m/s.
