Speed of Light

Moderator note: TheFrogger has been warned for off-topic posting in this thread. Deliberately wasting people's time like this is troll-like behaviour.

This is a minor warning, but due to accumulated warning points it means that TheFrogger will be taking a short break from sciforums.

One of my top two non-fic books.
My brain had stretch marks after reading it. (And I read it about 5 times.)

'The Elegant Universe' and 'The Fabric of the Cosmos' I liked them both. They are funny in that some ideas are over simplified and other ideas (which I consider hard) are left with no attempt at simplifying. Well, maybe they are simple and it was just me.

I still can't tell for sure from the extra stuff you quoted. It's frustrating because what I really want to know is the maths he is using to conclude that his "speed through spacetime" is c. I have read the book - a long time ago - but don't own a copy.

Ok. There are math notes for the chapter in the back of the book. Will post a picture here later.
Chapter 2 Math notes on page 392 for those with a copy.
Here's the pic, sorry it's so big.


I'm now thinking the slowing of time would shorten the world line of the object in spacetime??

Moderator note: A short break from the forum means just that. It has come to my attention that TheFrogger has been using a sock puppet to try to avoid his temporary ban. That ban has now been increased from 3 days to 2 weeks.

If any more sock puppets of this user are identified, he will be permanently banned from sciforums.

what is "t_B"?

t_B is defined in my post called: "Constructing Time from Four Axioms". The minus is an error it should read speed-in-time = c m/s.

If one need clock B to check clock A, one could equally well search for clock C to check clock B and so on until reaching a stage where there are no further clocks.
