Re: Negative Energy

After few hours of research i've decided to bring my question to the
group. IIRC, when a photon hits an electron of the electrosphere of an
atom, it gains energy and jumps to a more energetic sublevel (the
'excited' state). Due to instabilities, it releases back a photon and
then return to its original level (please let my layman terms to
pass). Ok, now the question: Lets assume for a sec that 'negative
energy' photons (anti-photons wouldn't be correct, since this have no
relation with anti-matter. ... "-photons" perhaps?) could exist and be
splited from it's positive energy counterparts (see ref. [1]). What
would happen to an electron in an atom hit by such a thing? I already
know about the dreadful consequences for the 2nd law, although
actually I do not understand then (why the overall energy isn't
conserved in the 'exotic laser' system??). The main idea is to
speculate the termodynamic consequences of an imaginary kind of
Freezing Dark Death Beam on
normal matter.

Note, though, that heat in this sense is not electrons being pushed into excited states in atoms. Instead, it is the random translational, rotational, and vibrational energies of individual atoms and molecules. To cool them down, you need only slow them.

The stumbling block here, then, isn't coming up with some form of "negaphotons," but rather handwaving some damping field that slows down molecules and keeps them that way. All that takes is increasing energy by an appropriate amount elsewhere to satisfy the first and second laws of thermodynamics (enough energy to make up for the kinetic energy sapped from the molecules, plus some extra to make sure that entropy increases).

There are two possibilities here.

Negative photons travel backwards in time or they travel forwards in
time and
carry negative momentum. (Holy tractor beams Batman!)

The backwards in time bit is strongly argued against by the non-
warning from
supernovas. In a supernova anything that possibly can happen is going
to
happen and no "backwards echos" of the events happen so it is not
possible to
travel backwards in time.

Negative momentum particles would be VERY noticeable in the particle
accelerator experiments and have not been noticed to date.

Note that I, too, saw this exchange on sfconsim-l. To be honest, I couldn't tell what this author was referring to. He is not describing known physics, or even reasonably speculated physics, of any sort that I'm familiar with. It sounded merely like technobabble to me.
