Time is a good thing... It keeps everything from happening at once.

It’s simple really. It’s because a body in motion tends to stay in motion until acted upon by an external force.

Seriously, dimensions are a property of the mind, a passing illusion experienced by an illusion. There are no 'dimensions' 'out there' because there is no 'out there', nor is there 'in here'. There is no inside, no outside, no distance, no time.

This is using a tape measure to measure itself. It is only 'it is', and even that is a lie.

Odd that a scientific journal would still be stuck in just four dimensions when matrix string theory says there are 11

Well WTF, did they think it was flat? Were there actually ignorant flat spacers out there?

so let me see...

first there were zero dimensions, then there was a BANG, and then there was 1 -> 2 -> 2.9XXXXXXX dimensions. great! spontaeous dimensional order generation from nothing at gazillion degrees, etc., etc, and then dimension 4 kicks in right at 3.0, and disorder started, ugh! but wait, thanks to disorder increasing (time), we reach the point of disorder where solar systems form and then seas and then organic chemicals (ain’t disorder great), and finally cells, and you know the rest.

SMH amazing! these people must be ohhh soooo smart.

It's not, it's 4 dimensional.

Because if it wasn’t we’d bump our noses all the time.

[onedoug]

M-Theory claims there are ii dimensions.

[frithguild]

Not too hot, not too cold, just right!

[Cruising Speed]

There is only one space, one dimension. For convenience, we use a three-coordinate system to uniquely identify any point in that dimension.

Btw, all this talk about extra dimensions 'rolled up' too small to see is wild speculation based on a mathematical quirk. And don't get me started on 'branes'.

How else would we blow up balloons?

[Moonman62]

time has one direction (forward) because entropy (a measure of disorder) never decreases in a closed system such as the universe.

...

Thermodynamic entropy is not a measure of disorder.

Time does not exist in and of itself. It is a by-product of matter, in motion.

Put that in your pipe and smoke it.

Neither qualitatively, nor quantitatively, can time be said to exist independently.

So I only know of 3 dimensions.

Why is space three-dimensional?
It is not. Go too far out and spacecraft will fall off the edge of space and be lost!

Reminds me of Abbot’s Flatland
