About time being a dimension (degree of FREEDOM to move back and forth). What is the speed of you FREE motion back and forth in time (change of time coordinate back and forth)?

So, I am sorry but you, who have done NONE to contribute into physics, understand next to ZERO of it.

Do not worry about me - my understanding is way ahead of yours. And I indeed from time to time correct some crackpot ideas. Usually in professional papers (peer rewiews) and in high level professional conferences in my field.

So, you layman misunderstanding of time and physics is typical.

You need to LEARN a little physics. 7th grade is not enough even to start understanding it. And it is seen from your posts - plenty of words without math. Nature does not work by words - it does by math as everybody here knows (except you, and one completely uneducated guy by name "careful universe" (Mikhael?).

So, write down an eqution - two about free motion back and forth ALONG TIME COORDINATE to support your claim - and you will most likely immediately see that you are wrong.

Please, don't lie that I do not know special relativity (SR) - we studied it in high school.

Most likely it is YOU who do not know it, not me.

Indeed, you claim that you UNDERSTAND relativity better than me, and that I don't understand it, right?

Let's just check your claim: please solve a simple SR problem. A rocket is moving in space with constant acceleration 9.8 m/sec^2. Find the velocity of the rocket after 1 year of space flight (starting with zero initial velocity).

We will see, who UNDERSTANDS relativity.
