*** I was thinking ... :Physics:Thoughts:
|
|
Since [[https://en.wikipedia.org/wiki/Positron][Positron]] has a negative energy according to [[https://en.wikipedia.org/wiki/Paul_Dirac][Dirac]] and it can be interpreted as an
|
|
[[https://en.wikipedia.org/wiki/Electron][Electron]] going back in time, what would happen to the [[https://en.wikipedia.org/wiki/Entropy][entropy]] of a system made out of
|
|
anti-matter?
|
|
|
|
Positron is the counterpart or the anti-particle of Electron, it has the same mass but the opposite
|
|
electric charge and negative energy. According to [[https://en.wikipedia.org/wiki/Richard_Feynman][Feynman]] we can think of Positron as an Electron
|
|
moving backward in time. Or we can think that Electron and Positron are the same thing, an Electron
|
|
that is bouncing forward in time and backward again. Bouncing between an Electron and Positron
|
|
characteristics. Anyway, according to the [[https://en.wikipedia.org/wiki/General_relativity][general relativity]], time is relative and not absolute and
|
|
two observers of the same phenomena might have different perception of time relative to their state
|
|
in spacetime. But another way of thinking about time in my head is entropy. According to the
|
|
[[https://en.wikipedia.org/wiki/Second_law_of_thermodynamics][second law of thermodynamics]] entropy of system increase overtime (to put it simply). Therefore,
|
|
future is the time with more entropy than today or simply the movement vector of time is in the same
|
|
direction as the entropy vector in our perception of time.
|
|
|
|
So, If Positron is moving back in time, does it mean that Positron's relative vector of time is
|
|
pointing the opposite direction of the entropy vector thus, entropy decreases relative to Positron's
|
|
time ??? If there's a universe made out of anti-matter, would it be just the past relative to present of
|
|
our matter based universe ???
