I understand that time will also measure processes that do not involve such movements . The rate of decay of subatomic particles is an example. Nothing moves and yet the process is regular and that is how we time the movements of other things.

Quote from: Atkhenaken on 26/09/2016 12:17:10All sub-atomic particles spin at the speed of light. How can something decay if it is not spinning? Impossible!Have you a reference for that.? I have heard of the term "spin" when applied to sub atomic particles but I think it is said to be different from what we normally think of as "spin".I am not sure it means these particles are in motion but I cannot say as I have not studied this area.

Quote from: Atkhenaken on 26/09/2016 13:42:28They must be spinning. Otherwise how can they decay if they are not spinning? Its just a matter of logical certainty.I prefer to rely on interpretations based on observations rather than anyone's conclusions based on "logical certainty".You haven't provided me with any reference to particles "spinning at the speed of light" as I requested . Did you make that up ,then?

Don't be subdued with complex and confusing diagrams. This is just a scam. Logic dictates that you can't add a fourth vector to a 3 dimensional world and call it space time. Time is not a length vector and never will be. So go join Carl Sargan and those other nut cases who believe in a fourth dimension and call themselves scientists? lol

He clearly doesn't know anything about this subject. This comment is proof of that.
Note - Dimension is term to describe distances while time is not distance related.
Time is not a dimension. ...
Quote from: AtkhenakenTime is not a dimension. ...Yet another ignorant comment. If did appear to be as arrogant as you have been then you could have simply asked me to explain it all and I would have. But no. Not you. Instead you think you know what its all about when in fact you've shown that you have it all wrong. But I don't explain math and/or physics to those who've come to conclusions like you have. Shame on you.

Shame on you.Time by itself has only a mathematical value and has no primary physical existence. It is just a thought process and doesn't exist as an entity in itself. Some scientists like to use the term "arrow of time". This is misleading. These scientists are trying to deceive us by using the word "arrow" in place of "vector". The reason they avoid using the word vector is because it has an association with distance. But, because they are sneaky space/time junkies, they need to use a disguised terminology to hide their deceptions. Don't be fooled! Note - People who give time a physical existence should be locked up in a lunatic asylum. lol!I don't think that you are capable of explaining anything. That's the real reason that you are not explaining. lol! What a joke! lol!
Please try to keep it civil.And don't confuse your inability to understand something with someone else's inability to explain it. Vectors don't need to have anything to do with distance. A vector is just a list of numbers. That's all it is. They can be used to describe coordinates in space (x, y, z or r, theta, phi) or spacetime (x, y, z, t), or reciprocal space (1/x, 1/y, 1/z) or color (R,G,B or C, M, Y, K), or even more abstract ideas (I dare you to look up linear algebra or eigenvectors, read about them for a good 30 minutes, or watch a few of the Khanacademy vids, and then come back here and tell me vectors only relate to space). There is no reason a vector can't contain thousands (or trillions) of numbers.
Are spacetime junkies anything like trolling junkies? Atkhenaken appears to be an expert troll so it will be interesting to get his take on the subject. Atkhenaken?

Thus, he cleverly sneaked time into his relativity theory hoping that nobody would notice that time is now a physical property instead of just and intellectual concept.
No, time was always physical. Are you saying that speeds and rates were merely intellectual concepts? If you take away time, then speed is only distance... Time has been an integral (no pun intended) part of Newtonian physics, and even the ancient Greeks and (ancienter) Babylonians had pretty a reasonable grasp of time.As far as "the arrow of time" is concerned. I don't think it is really about time being part of a vector so much as that people realized that time only changes in one direction. Things only get older, never younger. The major reason that people started talking about "the arrow of time" was in relation to entropy. As far as Newtonian mechanics was concerned, everything was purely deterministic, and any physically possible process that happened could just as reasonably happen backwards. Event A causes event B, which causes event C, could just as easily be reverse C causes reverse B causes reverse A. During the 19th century people realized that the world really doesn't work this way, that there is, in fact, one order of events that is more meaningful than the opposite order--time only moves one way.The easiest way to think about this is by imagining the fate of several ice sculptures on a sunny day. No matter what shape the sculpture has in the morning, it will be a puddle of water in the evening. The process of melting only makes sense one way. Sure, you can refreeze the puddle, but it won't put itself back together into a sculpture (and certainly not the one that it started as). If one looked at the reverse process, of a puddle freezing and growing into a beautiful statue, you would say that it was either impossible or magic (certainly not physics). That's all the "arrow" is about.
