Does "laser prism" deflect light,which travels through it?

But what about that plural refractions,caused by non-uniform gravitational field,cause gravitational deflection of photon?

Firstly xyzt written about this, but edited after.

Thanks. Photon direction change by spherical gravitation is lensing. Then photon direction change by gravitational prism is prisming. We can make experiments with gravitational prism.We should place lasers on arch of a circle and direct their rays to one point(for example to center of the circle).Then before the point the rays create gravitational prism. I don't know maybe scientists made similar experiment.

Well.Does only length contraction factor create lensing?Does gravitational slowing of time create lensing?

What is refraction effect in gravitational field?

Does only lensing cause refraction of light in vacuum?Does gravitational or electromagnetic slowing of time cause additional refraction of light?

Physics laws identically work in any frame. In observer frame the photons are free from the lasers .

Rays of blue photons have more energy than rays of red photons have energy(when quantities of photons are identical in the pairs of the rays), therefore rays of blue photons create more gravitation.Therefore blue photons should have less length( in observer frame) of wedge of their rays till sticking together.

Fast traveler1 has direction of moving with moving of the photons(relative to lasers).Fast traveler2 has return direction.They see different energy of the photons,therefore they should see different length of wedge of the rays till sticking together.They have identical speeds,only speed of traveler1 is positive and speed of traveler2 is negative,therefore they should see identical length of wedge of the rays till sticking together.This is paradox.

Fast traveler with the same direction of the photons sees less energy of the photons,and fast traveler with return direction sees more energy of the photons.Then they should see different distance of sticking together of the rays.But if each traveler have the same module of speed relative to the owner of the lasers,they shouldn't see different distance of sticking together of the rays according to length contraction of relativity.

Photon energy-momentum is just relative thing.Doesn't it make any paradox?

And does the gravity interact with massless particles?

How?Free photons are massless particles.

Then I recognize that I am wrong.

Does dark matter have momentum? They have similar equations.

Refraction of light in vacuum is indicator of gravitational slowing of time.Any gravitation creates slowing of time and refraction of motion.

Some time?It's much time. I think dark matter doesn't create resistance to moving object, therefore it has no momentum,therefore it can't attract,therefore it doesn't exist. Therefore we should search right formula.

Well. But what is physics of dark matter?

Position of objects isn't theoretical physics,it's astronomy.

Yes,my question is some wrong because dark matter theories are just astronomy of refraction of light. My equation is just theoretical physics. Yes, there is paucity of gravitational masses in congestions of dark matter on the map for a check of my equation.

Eye of moving animal was reflecting some light.

T=T0 R1/2c/(R1/2c - [2GM]1/2)

Usually a particle has some quantity of energy. And the any energy usually lets the particle be free from gravitational masses when the particle is free from electromagnetic force. Why "dark particles" aren't free from galactic congestions?

Doctor-bond didn't explain property of space of the OP. But space theoretically may work as gravitational mass, only when gravitational fields of masses cause this work.Then the space creates additional gravitation .
