A photon has energy and mass is a form of energy

Light has energy and therefore mass according to mass-energy equivalence.

Why do you guys never google this stuff on your own btw

>>12517110
Because acceleration due to gravity has nothing to do with the mass of the falling object (if it's negligible). General relativity specifies the trajectory based on the attracting body (black hole) alone.

>implying black holes are real
go on and give me a way to experiment with it

>>12517110
black sucks up light
whats so difficult to understend?

>>12517185
Is predicted by GR and GR has passed every experiment it has been subjected to, there's also a photo of it.

>>12517110
because you don't have to have mass to be affected by gravity

>>12517176
>acceleration due to gravity
"Gravity" is a description of mass accelerating not a cause of said acceleration.

>>12517110
Because like mass, light is an electromagnetic phenomena that gets it's magnetic component fucked beyond recognition.

"The way I would answer the question is to say "that's not a good question".
"Other than that's the way the world works"

Ah the ol' Richard Feynman non answer approach to...well not answering the fucking question. At least he mentions redshifting and all that, but this doesn't really answer it.

>>12517548
Black holes are part of GR, GR has passed every experiment ever, black holes are real and your brain is trapped in one, get fucked.

>>12517627
im not the person ur replying to but ur just repeating urself and going in circles, why dont u give a testable prediction or way to experiment with it

>>12517648
>why dont u give a testable prediction
GR already did retard
>way to experiment with it
>On 11 February 2016, the LIGO Scientific Collaboration and the Virgo collaboration announced the first direct detection of gravitational waves, which also represented the first observation of a black hole merger.[9]
Done. Next.

>>12517669
you forgot something very important in science, the ability to replicate it

>>12517627
>Black holes are part of GR
Which doesn't mean anything

>GR has passed every experiment ever,
And yet I see no tests performed on a black hole...

>black holes are real and your brain is trapped in one, get fucked.
You said absolutely nothing that alluded they do, nor did you provide proof of one. Don't let that stop you from getting the last word in when talking about your shadow though, not that it would mean anything.

>>12517669
>GR already did retard
Didn't even prove light has a speed in the first place let alone is "not affected" by a "black hole".

>gravitational waves
But gravity is a description, how can it "wave"? What are these "waves" actually made of?

>>12517702
>Didn't even prove light has a speed in the first place let alone is "not affected" by a "black hole".
SR is the one that says the speed of light retard.

Read yourself moron, read at least 101 shit before you open your mouth full of diarrhea.

>>12517686
>On 15 June 2016, two more detections of gravitational waves, made in late 2015, were announced.[22] Eight more observations were made in 2017, including GW170817, the first observed merger of binary neutron stars, which was also observed in electromagnetic radiation.
Done.

Because gravity is not a force.
Gravity is curvature in spacetime itself

>>12517739
>SR is the one that says the speed of light retard
The foundation of both theories is partly based on what light is/does and given that both have never proven that light has a speed or even travels in the first place they are both equally useless at telling me what light does around a "black hole".

>https://en.wikipedia.org/wiki/Gravitational_wave
Even though it's wiki, I'll give you the benefit of the doubt

>Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light.

>Space
>curvature
How is space curved? What property does it have that allows it to do this?

>propagate as waves
...Of what? It's what something does, the something I'm presuming to be "gravity" no? So what the fuck is "gravity" other than a description of mass accelerating? Waves of acceleration? It makes no sense.

>>12517110
Wouldn't it have a minuscule amount of mass?

>>12517110
The universe is a giant mattress and a black hole is like a big bowling ball sitting on it, gravity makes a dimple appear in the mattress and photons are like a marble you throw into the dimple, even though marbles don't have any mass they still get deflected by the gravity

>>12517781
I dont know if you are baiting or you are just retarded. I am guessing its both

>>12518797
>I dont know if you are baiting or you are just retarded.
You're the one linking wikipedia articles thinking they prove anything. Have you even read wikipedias terms of use?

>hurr gravitational redshift of light because photons are traveling in "gravitation well"
>to this day there is still no proof of a photon particle, or light traveling/having any kind of speed
>but no you're wrong because I'm hung up on the fact that it was SR that was assuming light has a speed and is a particle and and not GR...which wouldn't even work if there isn't a photon particle anyway.

>>12517122
>Light has energy
Correct.
>and therefore mass
Incorrect.
>according to mass-energy equivalence.
No such thing.
