So then we are all in agreement that the minimum and maximum value of a particle's velocity through space-time is c. So then it is impossible for a particle to stand still in space-time or ever change its velocity through space-time. What does this imply about space-time?

I think Brian Greene said this somewhere. I will check and get back to you. You write, "Under the assumptions of SR, you can change your 4-velocity. You just can't change your 4-speed." Where can I find out more about this? Can you give an example of changing the 4-velocity without changing...

Isn't it amazing that it is impossible to stand still in the space-time continuum? Isn't it also amazing that it is impossible to change one's velocity through the space-time continuum? It seems that the fourth dimension must be expanding relative to the three spatial dimensions. When we're...

Why do you think I don't know what space-time means? I think I do. Can you please define it?

rho--what don't I understand about relativity? why is everyone so negative on these boards? Merry Xmas everyone.

Why don't you believe that I've read those books? I actually edited a book on space time physics. This site is an embarrassment to physics.

Thanks for the correct answer daniel. So then it is impossible to stand still in space-time. Why is this? How can it be impossible to stand still in space-time? What does this imply about the underlying fabric of space-time?

Hello Doc Al Thanks for giving a correct statement. I do appreiate it. Here are the pop science books which have taught me about relativity: Einsteins' Meaning of Relativity Wheeler & Taylor's Spacetime Physics Misner, Wheeler, Thorne's Gravitation I do hope that these pop physics books are...

So you're saying that Brain Greene and Einstein are wrong? Briane Greene never contradicts Einstein, so if he is wrong then Einstein is wrong. Do any of you idiots have brains?

What is the minium velocity that a particle can have through space-time? What is the maximum velocity that a particle can have through space-time? Thanks!

Hello, I thought that Einstein said that distance and time could be measured in the same units--that they are both dimensions. Have you ever heard of relativity? I think it's fairly famous.

How far does a photon move in the time dimension when it travels for one second? How far does a photon move in the spatial dimension when it travels for one second? How far does a golf ball move in the time dimension when it stays stationary on a tee for one seceon? How far does a golf ball...
