Interesting. I have been reading a book (now and then) that put things in
a way I had not considered it before. It speaks of the universe really
being not space or time, but spacetime.
Again, that was the basis of the theory of relativity.
Motion must be consider realative to spacetime, not just space (or
time). What was wierd was this idea of a combined limit. If you are
moving totally in space (eg at the speed of light) then there is no room
left to move in time (eg an event horizon kinda thing).
Yep.
A parked car and you. You are not moving through space relative to each
other, and are moving through time at the same rate (And all it and your
movement is through time). When the car drives off, part of its motion
through time is diverted into movement through space, and thus its
movement through time is slowed down (relative to you).
After trying to get this, what remained of my brain began to wonder was:
If you were not moving at all in space (the absolute stillness idea -
relative to what I dont know - bear with me). Does that mean that you are
moving totally in time. Would time just be over in an instant?
Again, the reason it's called the theory of "relativity" is that motion can
only be measured relative to some reference frame, and -- unlike what is
presumed in Newtonian physics -- there is no such thing as an absolute
reference frame to which everything can be compared.
Then it got all freaky and my brain stalled.
At least you got that far :)
