What is " time" & does it even exist??

Answer 1

time is relative to the observer according to Einstein's equations. As a traveler approaches the speed of light time slows down. However, an observer on the earth would not see any change in time. When the traveler returns he would find his friends and family had lived many years whereas only a short time had passed for him. They have actually proved this theory by experiment. They used atomic clocks flown in an airplane and one on earth. The one in the plane showed less time had passed (very small difference since a plane is slow compared to the speed of light). So, time exists and is apparently not constant for all observers.

Answer 2

Time is simply our way of measuring reality. For me, my current reality is at the point in time when my half of the planet is facing away from the sun. Does that mean anything? Not really, except that I know that within a short number of hours, my half will be facing the sun again, and there are certain tasks I need to accomplish before the next sun down.

Time only exists as long as we believe it does.

Answer 3

Two distinct views exist on the meaning of time. One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence. This is the realist view, to which Isaac Newton [1] subscribed, in which time itself is something that can be measured.

A contrasting view is that time is part of the fundamental intellectual structure (together with space and number) within which we sequence events, quantify the duration of events and the intervals between them, and compare the motions of objects. In this view, time does not refer to any kind of entity that "flows", that objects "move through", or that is a "container" for events. This view is in the tradition of Gottfried Leibniz[2] and Immanuel Kant,[3][4] in which time, rather than being an objective thing to be measured, is part of the mental measuring system.

Answer 4

The old "time," and the one most people use/believe in today is like a one-way road that never begins and never ends.

A newer approach is like a series of railroads that can loop back on themselves.

Others also believe that time does not exist, that it is just an invention of man.

Answer 5

Time definately exists.
The only reason we have a measurement of time is thanks to the Greeks.
Before they figured it out, there was only three times a day to be recognized and it was sunrise, noon, and sunset.
But you have to remember, time didn't mean much to anybody in those days. It was a simple time with simple people, so they didn't have a need to keep track of hours or minutes.

Answer 6

Much too long CJW!

Dose time exist? Certainly - its the one thing that holds the fabric of the universe together!

Distances, Orbits, Interstellar motion, are all measured in time.

A "light-year" is the standard measure of distance, and is the distance light travels in a year.

When we look into space, we are looking into the past, as the images have taken years, decades, centuries, to reach us.

Answer 7

Time is what keeps everything from happening all at once.

Is it real? From our finite, limited perspective it sure appears to be real. Is it really real? I don't think so. It has no mass, no energy, and exists only in our minds.

The Aztecs said that man was the bearer of the burden of time.

Answer 8

It doesn't exist in its self. We continually recreate it by counting and keeping track of our results. If we stop counting, it goes away. Of course, there would be a lot of confusion among humans at first but, we would eventually begin to live more natural lives and be less stressed.

Answer 9

It is a unit of measurement. Time itself does not exist, but many people use it which is odd... anyway thats all.

Answer 10

time is simply an illusion with a purpose
