The first bit is well documented. Einstein (and others) supposed that gravity could bend light. We first observed it around the sun at total solar eclipse, and now it is a tool for astronomers and physicists alike.
But I cannot find anything supposing the reverse. Mechanics aside, if we could bend light, is there anything saying that it would or would not create a gravitational field?
My assumptions are this:
A smaller radius of curvature would create a larger gravitational field
This makes sense. In gravitational lensing, a larger gravitational field will result in greater bending/curving of a light beam. Hence why we cannot detect light being bent by a mosquito.
A more powerful beam of light - curved/bent with an identical radius of curvature to a weaker beam - would create a larger gravitational field than said weaker beam
It has been years since my physics days, and so I am unsure of this second assumption. That is to say, I cannot recall if the inverse is true (that a higher energy beam of light will bend/curve less for a given gravitational field). A couple quick searches show no dependency on energy of a beam of light, when calculating deflection due to gravitational lensing.
Thanks in advance.
