On a related note, someone once said "Obama is a member of AlQueda and is gonna..."
I replied, "...tl:dr: If Obama AlQueda, Obama bomba da world already".

In cases like that, the person is either incredibly stupid, or just trolling.

The response in either case is to the denounce the person, and ignore their argument.

Relevant to the thread.  Never ever ever just dismiss somebody like this, that's not how you should undertake a discussion.

[Descan]

Never ever ever? Even when they're blatantly trolling? Or so stupid that they're not going to change their mind at all?

I'll grant you a trickle-effect on the audience, just because the person you're arguing with won't listen doesn't mean it won't affect people reading/listening, but you're not always going to have an audience.

[MaximumZero]

If there is no audience, you're not on the internet. If you're not on the internet, you can punch the bastard.

[Mr Space Cat]

A girl wondered how scientists are able to determine astronomy such as the distance of celestial bodies in light years or determine that black holes have a center of mass called a singularity. I think she was just overcomplicating things.

How do they know the singularity is in the center if they can't even see the black hole in the first place? It's trillions of miles away too, how do they calculate this stuff?

I was tempted to snarkly remark "!!SCIENCE!!" but I didn't. What I found "Stupid" was that the term singularity is simply the term for the black hole's center of mass, which can be assumed is the most dense part of the hole because it's the center. The center is probably gonna be in the middle of the hole, that's what makes a center a center. Likewise gravity draws everything towards the center of mass, therefore black holes suck everything down to the singularity point. They could just as easily have named the center "Bob the Horrific Suck-Hole of Spaghetti Noodles" and achieve the same results, with slightly more awesome.

Anyway. Woo, high school senior level astronomy class!

Because black holes are in fact mystic space portals that defy physics and send you through space and time, right?
None of this 'escape velocity >= c' bullshit. Next you will be telling me they don't have spiraling arms!

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.

[Putnam]

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.

[Hanslanda]

Nor are they particularly dangerous, methinks. >.>
To an outside observer, someone falling into a black hole would just stop falling at some point and kind of hover there. Although, the person falling in would start falling slower and slower until they spaghettified, but you know. Details.

[Putnam]

They're actually less dangerous than normal stars, at least when they aren't radiating stuff, since you can orbit way closer without entering.

Hey, I've watched tv, you can't fool me.
A black hole is the astral equivalent of drugs. You go through and everything gets all wavy and when you come out you aren't sure where you parked your car.

I remember when I first figured that out, basically all by myself. I was so proud of myself and I didn't even realize that actual scientists probably already knew that

Holy crap so many ninjas.

... I learned that on TV, brah. TV: Sometimes it contains knowledge, but that's okay, watch Family Guy instead.

Scientists are too busy going, "Oh god what is it doing to my equations?! No, oh god pi what have they done to you?! That 2 doesn't belong there! Square root of negative 1?! That's not even a real number! OH GOD OH GOD D:"
