why these niggas be saying it dont have mass? did they ever slow down a photon to check?

i think it doesnt have mass because if you shine a torch at a wall, the wall doesn't move

>light is massless
says who? get ma meaning?

>it justs has inertia and momentum
how it got them without mùass nigga, isnt momentum calculated with a mathematical expression that uses mass? yet dem nigga be saying its 0, yet momentum aint 0?

>>11096331
>i think it doesnt have mass because if you shine a torch at a wall, the wall doesn't move
nah nigga it do
you just cant see it because you re tied to the wall with like fucking electromagnetism and shit
its like when you throw a basketball at a wall, it dont move but the basket ball has mass, it be like a watermelon

**RESTING** mass, that's important distinction

We know because math and shit, also see below

>did they ever slow down a photon to check?
Yes, but like everything in physics, this doesn't give you absolute value, only upper bond. It's something like "must be less than 10^-53 kg", I don't remember

nigga what
dafuq s a resting mass? mass is mass isnt it? lorentz factor and all that BS member?

shomedat

nigga why cant you make like a bunch of fucking tiny nigga photons, with a laser or some shit so they b all the same, and then calculate how many you got with math and the energy you used, and then measure the effect of that mass of photons?

also I just membered the fuckin kugelblitz, aint that a thing? how you get a blackhole that dont got mass? shit nigga some1 b lying

Light doesn't have mass because light does not exist. It is an action of the medium known as spacetime now, and known as the aether for several thousand years before now. This medium has mass, and as such it is able to communicate momentum through collision with massive bodies.

Light isn't impacted by gravity in the classical sense. It's path impacted by the spacetime curvature of object with mass.

You can't slow down a photon. Any particle with energy but no mass will move at c.

>>11096331
The wall does move a little actually. Because light has momentum but not mass.

so gravity?

If you like, sure. But then we have to redefine gravity such that it's influence doesn't' require mass.

>yeah you can, a lab did it
In a vacuum? citation plz

>isnt that proof we live in a simulation?
It's actually not.

is thezre even a difference between the two forces? cant light bend space? is mass even real then?
if gravity works on things we dont think have mass and those same things can bend space and create gravity...

Everything in the universe is a massive body.
Distinction between objects is still necessary for engineering, so compelling the argument that there is no distinction between objects isn't really helpful. However, it should be noted that all of the matter in the universe is composed of one fundamental unit, and that unit is an action of the medium. Matter is distinguished from the aether in that it is a special case of the aether, not that it exists wholly separate from it in origin.
A hydrogen nucleus is essentially composed of conglomerated vortexes in the aether, and all larger elements are composed of hydrogen nuclei.
A body is massive if it resists change in motion. Since gravitational/ electromagnetic waves do not traverse the entire distance of the universe instantaneously, meaning they encounter some resistance, we conclude that the medium which they traverse is massive.

You are conflating the classical and relativistic interpretations of gravity. If troll, excellent work.

Classically gravity is just the attraction between objects with mass. In classical physics light would not be impacted by gravity.

As a simplification, in relativistic terms gravity is the result of spacetime curvature caused by objects with mass. LIght need not have mass to be impacted by the spacetime curvature of an object with mass. The cause of lights path change in this sense is not gravity, but they have the same underlying cause.
