Depends on what you are talking about. No Physicist would argue that time is a fourth spatial dimension, which is what dimensions typically refer to. Time can be referred to as a dimension when you're talking about an object's position space and time. You can put whatever unit you want on the axis of a graph and it becomes a "dimension." But time is definitely not a spatial dimension. For example, in the theories that the universe is 10 or 11-dimensional, time is not one of those dimensions. In fact no one really knows what "time" is. Some theories have postulated that time doesn't really exist, but is merely an observation of movement. IE it's the observation of entropy that we perceive as "time." Fascinating stuff, actually. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
