Girl at school holding up a black water bottle: 'But how can it be water if it's black?'

[SalmonGod]

Black holes: They're basically just a really fucking heavy rock in space. So heavy that their gravity bends light. They're not actually holes, nor are they black.

So black holes are kinda like Mr. T?

Spoiler (click to show/hide)

He's not actually black.  The sun's just afraid to shine on him.

[Loud Whispers]

They're actually not heavy, either (on a stellar scale). They're actually less heavy than the star that they came from. They're just really, really, really dense.

Don't you mean mass? Because in terms of weight they kinda hold the crown.

Also the really massive ones don't even have to be all that dense.

Yeah, that's not true, though. They're (probably almost kinda, well theoretically at least) infinitely dense, as all mass is concentrated in a single point. The "black orb" is merely the event horizon, a region of space where even light cannot escape from (hence it's black). It's also not a "a heavy rock".

I said have to be, not are.

Hawking radiation (which is light) escapes from black holes (though only through quantum shenanigans).

She:I'm not gonna be able to pass my CPR test because I have hiccups!
Me:Why dont you drink some water?
She:But then I'm gonna hiccup it back up!

What.

And then when I was talking to a guy about CPR she interrupted us with "Fish! I love fish, i've been drawing them all morning."
Dont know if insane, or just REALLY stupid.

Hawking rad isn't light, it's particles.

:/ You're both correct. They're photon / anti-photon pairs. So it's light and particles at the same time. Specifically, Hawking Radiation is a type of Black-body radiation.

Aren't all particles also light? de Broglie's equation says that any object with mass and velocity has a wavelength, though it's really small for heavy objects. Mind you, I only took AP Physics B. X3 No Quantum Physics 101.

Overheard a guy talking about how he broke up with his bisexual girlfriend because she was checking out other girls, oftentimes girls he himself was checking out. Said he would have preferred her to check out other guys, because he believed he was more attractive than any other guy she would have looked at.

Sounds like he was more angry that she was emasculating him than anything to do with jealousy.

Dude. Duuuuude. Talked about missed opportunities.

My SO is bi, and RedKing is Totally Fine With This Situation^TM.

Technically, everything is in potentia as a waveform (which represents a kind of probability distribution) until you observe it, making the waveform collapse, giving whatever it is you are observing a particle like form depending on what bit of the probability distribution the wave collapsed into.

Buckyballs have been shown to have wave behavoiur, but anything larger than the Planck mass would have a wavelength shorter than the Planck length and its Schwarzchild radius, upon which point shenangians would occur.
