<DIV><FONT color=#000080 size=2 face=Arial>Hi Chip,</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial></FONT> </DIV>
<DIV><FONT color=#000080 size=2 face=Arial>Thanks for that.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial>Unfortunately Adobe Acrobat tells me
that the file is damaged & can't be repaired, so can't be
opened.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial>You might like to send it again,
thanks.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial></FONT> </DIV>
<DIV><FONT color=#000080 size=2 face=Arial>From my perspective the reason that
light carries momentum is pretty straightforward:</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial>Light is energy on the move; if and
when it's absorbed by matter, it will become part of the mass of that matter,
and so will add to the momentum of that element of matter; when it's emitted
from matter it carries away part of the mass of that matter, and so also part of
its momentum. If light didn't carry momentum then a particle emitting
light would necessarily move faster in that same direction (conservation of
momentum); likewise a particle absorbing light would experience an acceleration
towards the direction of approach of that light (conservation of
momentum). Neither of these would seem to make sense or have any
reasonable explanation.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial></FONT> </DIV>
<DIV><FONT color=#000080 size=2 face=Arial>In fact the phenomena of both
inertial and gravitational mass are fully explainable in terms of the
consequences of electromagnetic waveform energy describing cyclic paths as
particles of matter. A full analysis shows that part of that energy
leaving at the speed of light would necessarily alter the inertial-mass response
of such a particle, and so its momentum; likewise additional energy being added
to a particle of matter, again at the speed of light, would likewise alter the
inertial-mass response of that particle, and so also its momentum. Both of
these changes fully support the notion that the photon is transferring not only
mass (as Einstein observed) but also momentum between emitting and absorbing
particles, in precise agreement with the principle of conservation of
momentum. Put simply, light HAS to carry momentum for the universe to
carry on working; if it didn't we wouldn't be here talking about
it.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial></FONT> </DIV>
<DIV><FONT color=#000080 size=2 face=Arial>More than this, a partial transfer of
energy from photon to particle - including scattering in any direction,
Compton-style, also fully fits the principle of conservation of
momentum.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial></FONT> </DIV>
<DIV><FONT color=#000080 size=2 face=Arial>In other words, light carries
momentum because it carries energy - and at its root momentum IS an energy-based
phenomenon.</FONT></DIV>
<DIV><FONT color=#000080 size=2 face=Arial></FONT> </DIV>
<DIV><FONT color=#000080 size=2 face=Arial>Best regards,</FONT></DIV>
