Default Photon bend another photon

I am a lowly engineer in aerospace, but have taken a few advanced physics
questions.

My question is, if two photon's pass really, really, really close to each
other -- will their paths be changed by one interaction with the gravity of
the other.

No.
Photons are not billiard balls, although they share some things in common,
such as momentum. What makes a photon different is that they can pass
right through each other. That isn't so strange, though, they can pass
right through glass too, a billiard ball cannot.

However, it would be a possible to see the things, the known manners, for
instance, along any state of anything, that a thing moves in the direction
along which, it is already pushed, that thing would keep moving in a
straight direction until some other force acts to slow it, for the simple
reason, that every action has an opposite and an equal reaction, along an
universal gravitation.

Therefore, along that matter, it would be shown that every object along the
universe exerts a force on an every other with its own gravitational force.

However, anything along that matter also, would be a strictly as absolutely,
a proportional to the mass of an each and would varies inversely as the
square of the distance between them.

Therefore, when the distance between two objects would be a double distance,
the attraction between them, would becomes a four times weaker, as it would
be shown as follows :

F = G Mm

Photon-(virtual)photon interactions have been observed in the
laboratory. There is no evidence that gravitation is present;
with the strong, weak, and EM interactions that swamp such a tiny
effect as gravitation.

You can do your own search on google on:
"photon photon interactions"

Well very small distances in QM are problematical due to the Heisenberg
uncertainty principle. But yes it is predicted that EM radiation will
interact gravitationally. Strangely though it depends on the direction the
beams are traveling - I forget which is which but if they pass in one
direction no interaction - if they pass in the opposite direction then they
interact. But the effect is so small there is little chance it will ever be
experimentally testable.

Thanks
Bill

Hasn't this been measured in the lab already?

I remember I asked a similar question a few months ago, and I found a
website reporting on an experiment which used 2 laser beams parallel to
each other.

When the laser beams where in the same direction, no interaction
occurred, but when the laser beams where in opposite directions, an
interaction of measured.

Or maybe it was the other way round.

But the point is, the experiment has been carrired out, and an
interaction was measured.

Beams parallel no attraction, anti-parallel attraction.

Was the interaction gravity or some other force??

Consider that beams parallel *should* have the photons closer,
longer (assuming that makes sense for light). So gravitation
isn't a detectable player.

I'd say that at least the EM fields twisted each other's
nipples... which is what sharp changes in E-field could possibly
do.

No. Photons do not have mass. Thus they generate no
gravity. Thus they do not interact gravitationally.
