Ernst Mach about time:
It is utterly beyond our power to measure the changes of things by time. Quite the contrary, time is an abstraction at which we arrive by means of the changes of things.

Albert Einstein about time:
Space and time are modes by which we think, not conditions under which we live." Time--the time that we know through clocks and calendars--was invented. http://www.britannica.com/clockworks/article.html

Roger Penrose about time:
The temporal ordering that we 'appear' to perceive is, I am claiming, something that we impose upon our perceptions in order to make sense of them in relation to the uniform forward time-progression of an external physical reality. http://www-groups.dcs.st-and.ac.uk/...ics/Time_2.html

Author about time:
In the universe one can observe only motion and not time. Time is a construction of the mind into which humans experience motion.

Julian Barbour gave his book title: The End of Time, The Next Revolution in Physics.

He has all reasons for this title. Existence of time as a physical reality has no experimental evidence. In all physical formulas symbol t means duration of motion. Universe is an a-temporal phenomena, time is of the mind, motion is of the universe. With clocks we measure duration of motion. The second is a unit with which we measure duration of motion. In 86400 seconds earth turn once around its axe. Second has no existence on it own, it came into existence when motion is measured by a clock. Second is a tool of the mind that man uses to measure duration of different motions. Motions by itself have no duration. Man give them a sense of duration by measuring them.

motion......perception (eyes)......elaboration (time)......experience (observer)

Motion is measured by clocks. With clocks we measure duration of the movement of body or particle regarding another body or particle. The speed of the motion depends on a density D of space. Density D in centre of planet or star is D = m x G, where m is a mass and G is gravitational constant. Density D is diminishing with the distance r on square from the centre of the star. Speed of time is increasing with the diminishing of density D. Clocks run faster on the top of the high mountain and slower at the sea side under the mountain. Density of space is higher at sea side and lover on the top of the mountain.

Density of space is increasing by going towards the sun. Time (speed of bodies and particles) is becoming slower by going towards the sun. That's the cause of "Mercury perihelion dilate".

Time moves forward in every direction. Atoms are spinning in perpetual motion. That macroscopic things appear to be still is an illusion. Einstein said: No Absolute Rest. This can only mean everything is moving in some manner.

Einstein said: when the station comes to the train; but only the train "moves through Earth's space" to get closer to the station not the other way around. If this were not so we would not know what is actually moving and what is not.

Motion is both an absolute and a relative. Imagine the universe as a whole and it imediately becomes obvious that things have a definite position and motion. If we loose that we don't have a picture of the universe at all.

I concur, I would like to add though, that while atoms do spin in constant motion, physics say that nothing can be perpetual Everything has an end, much like uranium is depleted when it loses all of the energy it once gave off, any other atom will do a similar action, only uranium does this a considerable bit faster than say hydrogen, because it is unstable and actually eminates energy.

I believe the hydrogen atom is predicted to be unstable in some models. But is there any evidence for this?
I don't think there is any evidence for unstable atoms that are not radioactive; at least not yet.

I don't believe so, but chemistry isn't my strong point, so I really don't know.

Black holes are the theoretical End Of Time in physics. In the theory of General Relativity time ends first at the surface or event horizon of a black hole then continues somehow and then ends again at the heart or singularity of a black hole in a "crunch." Time not only ends in this theory but it ends twice!!!

If time has no end and the universe keeps expanding at an increasing rate its future would have to be infinite.

If time stops then for how long does it stop? Laughing
