Comment on Can you have an infinitely long wavelength of light? Or is there some maximum?
remon@ani.social 1 week agoThe idea that a and very small wavelength would cause a black hole doesn’t really make sense to me since I thought a black hole requires mass.
It’s mass OR energy.
Light, even though massless will still bend (and be affected by distorted spacetime) because it has energy in form of momentum. (See: gravitational lensing).

It is affected by gravity. But does it have gravitational pull? The thing about black holes is that they have a lot gravitational pull.
I’m asking because I honestly don’t know.

They do indeed. It’s totally minuscule of course.
Everything that has energy deforms spacetime and spacetime affects how anything with energy moves.
