You'd have to see his face. That was a genuinely confused enlightened person.
I disagree. For example if you have a totally empty space, let's say a box where even the single molecule has been sucked out, could you say that the space inside the box exists? Isn't it just a measurement of the distances between the box sides? I'd say that the space exists only as a mental operation.garyb wrote:"dimension" means "a measurement of spatial extent".
time is a measurement of space just like depth or width. ALL the space is here whether you have sense organs to "see" it or not.

If space is defined by a set of points it is no more existing than the points themselves. Do the points exist? Like space, they are abstractions, mental operations.garyb wrote:alfonso wrote:I disagree.

yes, the space exists even in a total vacuum.
but be that as it may, the definition i gave is dictionary. the word comes from latin, dimensio, a measuring. of course space is defined as a set of points, which as you remember have location, but no dimension.
these things are not matters of opinion, but are specific terms relating to specific realities.
stop being so disagreable.
nonsense. you're speaking like Humpty Dumpty(words mean precisely what i say they mean and nothing more).Shroomz~> wrote:Gary, definitions are NOT 'accurate'. They're only what we perceive as possibilities (despite what we've been told).
this is true for the colloquial meanings, but not for the word's foundations.stardust wrote:definitions are not time invariant.
clocks are local and the pathintegrals show different propagators.
