"Sorry, another question on time: Is time slowed down for something put in a freezer just as it might be if that object travelled at a great speed. An iron bar for instance travelling at a great speed would shrink and time slow down, the same bar in the freezer would shrink and time would slow down."
The answer is no, in the sense that what hapends in the freezer is not governed by special/general relativity.
in the freezer the bar contracts because of temperaure differences, and not because of special relativity length contraction.
As for time slowing down in the freezer,I don't think so!"Does time pass slower in ice-bound planets or is the concept completely different."
Different concept.
"On one hand we imagine time as marching steadily on, while on the other we seem to be able to manipulate it quite easily."
I am not so sure anyone can manipulate time,for the time being at least, let alone to manipulate it easily.
"We have Mass=motion(or energy) I assume from this that Mass=time, motion=time."
My first reaction to that was "Huh?".There is no equality in the first,mass is not equal to energy, it is just equivalent (remember E=m(c^2))
As for the other two equalities,they do not exist in any theory I know of."So the rate at which an atom viberates seems fundamental to time and mass and motion. Which is most fundamental if any, time, motion, or mass."
Rephrase.In what sense do you want to know which is more important?I am afraid that (unless more details of the question) you want to compare apples with oranges and with donuts.
"It's not exactly the question I want to ask, but the freezer one intrigues me."
Then try to write it down more carefully, so that I have a better idea of what you are thinking of.
