Default Re: Is Time Tangible?

Time isn't very tangible. It does exist, though. We see its effects and know it's there. Time is actually partially an invention and partially an observed phenomena. It's kind of a concept of continuous existence.

Clocks are able to ticket very precisely at one-second intervals. If time didn't exist, clocks would have no fixed intervals of ticking, because there would be no way to measure how precise the ticks were. There would be no purpose, either. The way in which we measure how precise or accurate something is, or how long something occurs, is called time. It does exist from this logical standpoint. That is because it is being defined as a concept.

We can sort of conclude from this that time is traveling at a constant speed. We never see it adjust under every-day conditions. This makes it hard for some people to determine whether or not it exists or is a mere description of continuum invented by us. According to Briane Greene's "The Elegant Universe" book, we would have to watch objects move at ridiculously fast speeds (about 0.9 times lightspeed) to observe any difference in the speed of time's flow. We can't do that now. eh?
