what is time?

  • And distance between stuff changing is a consequence of time - for without time there is no concept of distance between stuff changing.

 

And how can you prove that distance between stuff changing is a consequence of time? You can't prove that. In fact we are moving, running everyday, and the distances are changing without any need of time.

Robin, I said that change and time are different and that you can have one without the other (both ways).

 

Time and change/motion are the same thing. The only difference is that when we use the word "change/motion" we refer to the change/motion of a single thing, and when we use the word "time", we refer to the change/motion of everything in the universe.

You CAN have one without the other? Well, you CAN have Santa Claus as well, the problem is to prove it.

Belief regardless of evidence is not science, it is religion.

You misunderstood.

 

I said TIME is absolute whether you like it or not

 

That believe word is figurative - don't get confused

 

This is right and soundly part of Science and not Religion

Unless you have some evidence that time is absolute (and you don't) then it is a religious belief, not science.

I think I understood quite well. We have strong evidence that it's not, and you believe it anyway. That's religion.

Time and change/motion are the same thing.

motion and time are not the same. you need time to describe motion, for example the speed of an object is given in distance/time.

 

time =/= distance/time

 

the rest of your post uses words in an unconventional sense. i don't know what you mean when you say time describes universal motion.

There are two meanings for TIME !

 

One is something like AGE etc which is absolute about any Body of matter if we can calculate that AGE with respect to the Absolute Time.

 

The other one is Time being used as a parameter in Space-Time or Movement of Bodies through Space, particles, Planets etc and how that parameter behaves in that calculation - whether Linear, Curving , Vectorially Varying etc needing higher maths to depict its value though every one of those values can be mapped into the absolute scale if we know our moorings in Space !!

You obviously aren't aware of the Twin Paradox: http://en.wikipedia.org/wiki/Twin_paradox

Nope.

Yes, we need time as a sequence to describe motion, but not as a dimension. The sequence of all the motions in the universe is what we call time, and we measure it with some constant motion (like our clocks). I think it's important to use the right word. If we replace the word dimension with the word sequence, we resolve every debate regarding time. Can we reverse all these motions? No, if we could rewind or forward every single motion in the universe, we could time travel.

Again, just to to clarify: does time exist? Of course yes, but as a sequence of all motions, not as a dimension.

i'm not sure who "we" is in this situation as you are the one proposing this new definition of time.

 

sequence would not be the "right word" given its usage in the mathematics. i guess you could call it a parameter if you're so opposed to dimension, but that word would probably not be appropriate given its usage in Special and General Relativity.

 

i'm not sure how to respond to the rest of your post. you don't provide any reasons why swapping words would resolve any problems, or any clear examples of real problems that terminology seems to be causing.

Yes, I read it.

 

I have heard of this earlier too.

 

Can you tell me what does this mean and what are the Conclusions.

It means that the rate at which someone ages depends on movement and gravity. It is not absolute.

 

There is no paradox.

Indeed. Every single example of a "paradox" in science is simply a label used to describe something which has surprising results.

Then perhaps you could explain how our most successful theories, which treat time as a dimension not as a "sequence", are able to work.

The theories work even if you use the word dimension, but don't you think it's a misleading word? A sequence is just a sequence, love is just a sentiment, but you would never associate the word love with dimension, unless you use it in poetry and say "love is our most important dimension".

I don't agree with :

 

someone ages depends on movement and gravity

 

I mean I don't agree with that kind of false calculations.

 

AGE is what AGE is : Everyone knows that, except some confused souls !

We are all moving at a terrific Velocity [because of the same Gravity]

 

What about that ?

Then you need to show why general relativity is wrong (despite making accurate predictions and being used in all sorts of technology - e.g. the Internet). Because the evidence disagrees with you. And if it is a choice between evidence/reality and some unknown guy on the Internet, I am going to stick with reality. Sorry.

But why are you not telling me the effect of the Gravitational Velocity on all of us and our age ?

 

You know at what speed we are hurtling through Space ?

 

Just take your Mass and multiply it with the Mass of the Universe and apply Newton's Gravitational Law with inverse Square of the Distance to the Center of Gravity of the Universe and that will be the Gravitational Force applying on you [and me as we are all in it with every Particles around us - add Bosons, X-Bosons and Everything - including the Cern Lab which tracks all particles]

 

Now tell me WHAT IS MASS ?

 

That is something NO ONE KNOWS !
