2008-04-19: What is Time?

[Profpat]

May I suggest a compromise gentlemen, perhaps the topic should be Quantum Mechanics. This would include string theory and others.

Best,

Should be a good topic..

Sorry I missed that chat; my grandkids where left with us for the weekend and that was much more fun.

It was good that baudrunner joined in after the first 50 minutes of chaos to inject some rational thinking into the chat. “Well done Steven”.

I would like to inject a little rule-of-thumb for those discussing the speed of light as it relates to time:
Light travels through the same quantity of spatial density for a given increment of time.
Gravity is a gradient of spatial density.
Acceleration causes an increase of spatial density of the object being accelerated. (relative mass)
Time dilation is the result of the variance of spatial density not the variance of the rate of time. Only the clock goes slower!(the measurement)

Is the horse dead yet?

Yes David, having a professional engagement that I had to fulfill, I missed the chat and had to catch up later. But I saw it exactly the way you did. Overall it was very disappointing and lacked direction. Of the inputs only baudrunner seemed to be on track.

Baudrunner - would you like to start your own thread on this subject - or even continue this one?

regards
Felix

You guys are right baud is a bright chap. BTW Felix he agrees with me and Uncle Albert that time is relative.

As I understand it, Special Relativity has light propagated rectilinearly and at constant speed as judged from inertial frames of reference. General Relativity has light (like everything else) following a "world line" dependent upon spatio-temporal location in gravitational fields generated by massive objects. The straight line of Euclidean space is like the world line of the non-Euclidean space-time of the gravitational field only in the sense that both, in their respective realms, are the shortest distance between two points. Whether a thing is moving in a straight line in Euclidean space or in a world line in a gravitational field, it is still moving. The real question is how is motion possible in the first place?

Hi Neri;

Because of heat energy. No heat, no motion. Or no motion, no heat. At absolute 0 nothing moves.

Pat

P.S. The initial heat, or energy, or motion came about because of the big bang.

Good answer Pat, but what are we really measuring when we measure temperature? Energy?

My naive thoughts tell me that if we make motion the absolute, and we build a framework which is trying to equalize its matter in motion, degrees of temperature takes on the roll of spatial degrees of freedom of the fundamental material building blocks, and thermodynamics become spatialdynamics, whereby the potiential for motion (temperature difference) between two massive bodies is equivalent to the spatial to particle ratio/density between them.

Absolute zero then becomes massive formations of matter which contain only plank volumes of space, and an absolutely hot system is a symmetrical arrangement of all of its matter, whereby the max amount of motion potential is possible.

In a closed universal system, the total motion potential (total temperature/energy) would then be equivalent to the total volume of unoccupied space, thus conserving it, as it also is now finite and absolute, along with the matter and motion within it.

[Profpat]

Molecules have internal structure because they are composed of atoms that have different ways of moving within molecules. Kinetic energy stored in these internal degrees of freedom contributes to a substance’s specific heat capacity and not to its temperature.


Hi Analog;

Your naive thoughts are beyond this humble accounting professor.

I always related heat or temperature to pressure,
which I guess relates to degrees of freedom.

It was my thought that the pressure was so great in that little tiny ball at the beginning of our universe, that it translated to temperature.

Since the pressure was so great, so was the heat

Just my thoughts on the matter.

Best to you,

Pat

Hello Pat,

Have you ever heard of the kenetic theory of gases?

If so, the theory implies that the molecules of a gas are like billiard balls and they create pressure on a container as they collide with it and each other trying to equalize the energy which they contain, due to a differential in temperature/heat.

It implies that their individual velocities are relative to the energy each ball contains, thus the individual collisions take place with more/less force, as the total volume of gas attempts to transfer its energy from ball to ball, thus equalizing the total volume, whereby all collisions take place with the same force.

Our universal system could be somewhat viewed as a kenetic theory of everything, made up of fundamental billiard balls, but rather than different degrees of velocity which is implied by the admittance of energy, the velocity of all of the balls, thus the entire system, is absolute and finite and the balls are actually trying to equalize the varying spatial densities between each ball. Rather than colliding with more/less force, some travel farther than others before impact.

Does this help in my explaination?

P.S. Measurements of time would also be finite and absolute within this system as they are governed by plank degrees of motion. The total amount of time (elapsed motion) the system had to operate with would be the only infinite entity.
