It's hard for me to believe that a black hole would give off such an incredible amount of light. Is this what it'd look like if you had a telescope camp out on the black hole for a month? Or would a person flying by look out the window and see this monstrosity?

It would be extremely bright. Think about the pressures on that matter from the intense gravity. Its being squeezed thinner, being torn apart from tidal forces and its moving at near the speed of light. And as it falls its converting gravitational energy into heat.

Also keep in mind we can see accretion disks around supermassive black holes from galaxies billions of light years away. Even the one in our own galaxy glows.

Only the hole itself is black.

"They get so hot, they don't just glow white, they glow X-ray, converting 10 percent of their total mass into pure energy. For comparison, fusion warheads only convert 0.5 percent of their mass into energy. Understand: Black holes create a place where dropping something releases 20 times more energy than thermonuclear detonation."http://www.cracked.com/blog/6-mind-b...t-black-holes/

Good sci-fi will have enough science fact in it so it doesn't strain credulity.

Nothing about Gravity "strained credulity" for the average movie viewer. Us science geeks? Sure. But the average person seeing that movie wouldn't have thought twice about anything in the movie. Average people don't know or give one sweet fuck about orbital mechanics and the like.

Jimmies rustled. I hate it when people say something is converted to pure energy. It is like saying something is converted into pure length or width.

Agree completely. Gravity was a good -movie- because it has a good, intense pacing to it. Sure the mechanical science behind why stuff works was almost all bunk, but the presented science of them floating around, how the space debris hit them ect was all actually quite accurate. It was enough to appear accurate on glance to any average person, so enough to get the job done.

I wasn't making a judgement about Gravity. In fact, I haven't even seen it. I don't consume much pop culture these days beyond a few shows like Mad Men, Boardwalk, etc.

But the average consumer of Hollywood movies doesn't read sci-fi novels or generally contribute to the economics of sci-fi culture, although they are more and more every day with the popularity of nerd culture, but my point stands thatmostgood sci-fi still needs to be grounded in some sci-fact.

Ehh some do, but some really popular ones have nothing but discrepancies from sci-fact. Look at the entire star trek universe or classics like war of the worlds, enders game more fiction than sci-fact.

Gravity is grounded in sci-fact.

I think people become victim to some sort of fact-based uncanny valley, where the more a film promotes the idea that it's realistic, the less tolerable any errors are.

Good point Tuco. I think the more unbelievable, far into future type stuff tends to be less scrutinized for sci-fact than the current based sci-fi.

Nahh, its not about winning, bro. I get what you are saying. They were all well written pieces of fiction that were believable up to a point.

McConaughey was great in dallas buyer's club. He's an easy cast for mediocre action/comedy/romance films, but he's actually better than average.

I want them to make a movie out of Fallout. Science that shit up.

Actually all of that was inaccurate. None of the debris behaved in anywhere close to the way it actually would.

Also whether the story was good is subjective. I imagine if you told everyone who likes the story that the science was completely inaccurate, their opinion would rapidly change. That has been my experience, in any case. Hollywood is lucky people are ignorant of physics, I guess.
