Talk: Dimension

From open-encyclopedia.com - the free encyclopedia.

"We can move up-or-down, north-or-south, or east-or-west, and movement in any other direction can be expressed in terms of just these three."

Can you really speak of movement in terms of just the three spatial dimensions? Doesn't the very concept of movement depend on the time dimension? Without time all you have is position and no movement. Right?

Movement is change of location. One moment a thing is here, and another it's there. Moving is not necessarily related with time. --Inyuki 12:09, 2 Dec 2004 (UTC)

Why (how come?) our space have three dimensions of space and one of time? How did the space originate? --Inyuki 12:09, 2 Dec 2004 (UTC)

How would a change of location occur except through or in time? Hyacinth 00:15, 3 Dec 2004 (UTC)
