Wait, photons can be converted into matter but matter is affected by gravity whilst photons are not. Sheeeeeeit the Universe is terrifyingly simple, too simple for our minds to comprehend

there is only one way to end this
...with an obscene amount of light?

(yolo)
you
only
light
once

Also he's in his late 50's making him the biggest and baddest among the greymuzzles.

wut

shit i thought that chakats are fairly new beings, didn't know that this guy made his legacy off of them

its a mad world
From a quick reading of furry stuff, it would appear sergals have been the new chakats for the better part of a decade or so.

Not that I would know anything about that.

okay i'm like 99% sure you're shitposting but

1.photons are affected by gravity

2. photons can be converted into matter, yeah, but you gotta conserve lepton/baryon number, so you'll end up with an anti-whatever whenever you make a whatever

Light is affected by gravity, LW, that's why black hole are fucking black.

DUH x9001.

The dark side is just the side photons don't like

At some point B12 puns stopped being funny.
Or maybe they were never funny? My memory is a bit foggy on that.
This particular round's just notably bad. The ay nonsense isn't helping.

It's known as the Oppai-Kaiju effect. The islands of Japan generate a sort anti-gravity field, which allows breasts to behave as if in microgravity. It's also what allows Godzilla and friends to become 50 stories tall, and lets ninjas run up the side of a skyscraper.

Yeah, it would've been bearable if it hadn't devolved into the crappy memes.

The weirdest hang-up I've ever seen people get on is light being affected by gravity.

Like, they're really sure of the idea that only things with mass are effected by gravity, which is wrong, but then they say that Einstein must have been wrong because it disagrees with something that is known to be wrong

i don't get it
Maybe because they learned the gravitational force equation


Obviously that's an obsolete model, since it doesn't explain gravitational lensing.  It's the one that pretty much works except for astrophysics though.  I certainly don't know how to calculate the gravitational pull of a massless thing, and the very concept is annoyingly contrary to what I understand "mass" to even be.

I mean, now I'm reading about solar sails and realizing that photons have significant momentum.  But no mass.  What the fuck

I'm not saying they have mass, because I know that an object with any mass moving at c would theoretically have infinite relativistic mass (and would take infinite energy to accelerate to that point).  But the normal conclusion from that is "So obviously they don't have any mass at all" not "They technically have no mass, but they behave like light (unheavy lol) particles despite moving at c.  Pulled around by gravity, and transferring momentum on collisions".

Relativity is WEIRD.  Here's something I found which seems like an explanation, of sorts... "Photons of light are not technically affected by large gravitational fields; instead space and time become distorted around incredibly massive objects and the light simply follows this distorted curvature of space."  Dunno if that's true, but sounds good.

Relativistic mass is not a thing. Or rather, it's an obsolete notion that just sorta leads to confusion and doesn't add to anything.

E=mc2 is wrong; the real equation is E2 = p2c2 + m2c4, where p is momentum, m is mass and c is the speed of light (or length/time)

On most forums, arguments derail into shitposting. On Bay12, shitposting derails into arguments.

Hard science is like a sword, and soft science is like fear. You can use both to equally powerful results, but even if your opponent disbelieve your stabs, they will still die.

No, I'm pretty sure it went argument -> shitpost back there.

Dammit. I saw LW and physics and jumped to conclusions. Should probably check these things first, huh.

It's because Newton's equations are only approximations for what actually happens. But you can sort of cheese it by working out what value you approach as you approach a mass of 0. You don't get the answer that's seen in real life, but you get one.
General relativity works far better for light. You should probably use that if you want to be doing calculations about how light is affected gravitationally.

Not that I know how to, just that you should.
