Re: [Phys-l] Arrow of Time Issue



Hi Bennet-
I'm not sure I understand your argument.
As I see it, "time:" by definitiion, can only "go forward", so that gives a meaning to the phrase "go forward". So the statement that entropy can only increase, means to me that: as iime increases, entropy increases. Do you have a different understanding?
Regards,,
Jack

The second law of thermodynamics says that entropy must always increase or remain constant, therefore time must always increase (go forwards). CPT symmetry says that charge, parity, and time are all reversible, therefore time can travel forwards and backwards. We have experimental data showing both to be true, yet have no idea how thy are related.

This is my first time posting in Phys-l, C.V. Britton recommended I join. I am 13 years old and have a knowledge of everything from calculus I up to some differential equations. In my spare time I solve equations and teach myself new principles on the whiteboard I have in my room. I have been researching physics for a few years now.

I believe I have a plausible solution to the dispute between CPT symmetry and the second law of thermodynamics. I believe time to be a conservative, connected, four-vector quantity and the quintessence (dark energy) to be the scalar quantity. In short I would be trying to find some sort of Lagrangian to describe the vector potential of time, therefore describing the laplacian which should be equal to zero if the field is irrotational.
