| It really creeps me out watching this. What you have to remember is that, as you're falling toward the black hole's event horizon, you are seeing the entire future of the universe pass you by (since from your perspective time is going faster and faster outside.) Fuuuuuck. |

| Don't forget your friends at home with the telescope are watching you move more and more slowly, until you are frozen forever at the boundary of the event horizon, that same stupid grin and thumbs up you had 2,000,000 years ago, nothing more than a progressively redshifting spec of radiation. |

You're not going to get ripped apart until you reach the event horizon, are you? |

| Doesn't that depend on the size of the black hole? |

The gravity and tidal forces would kill you long before you got there I'd imagine. |

No, he's right. You'd be spaghettified long before you got to witness the entire future of the universe. |

I can't understand the obsession of trying to visualize the "fall" into a black hole. I've seen 5 or 6 different renditions of it, including one in an IMAX theatre.
It makes very little sense, since it's not something that is ever going to be testable, nor is anyone ever going to experience it.
You would be cooked by stellar radiation even getting within a few hundred light years of a black hole. Even if you could shield from the radiation, the gravitational and tidal forces (as someone already mentioned) would turn you into a dribble of liquefied proteins and water a pretty substantial distance from any noticeable changes in space-time.
But, I guess it's human nature to try to imagine what it would be like... .  |

I think it's akin to that thing we call morbid curiosity. I have an overactive imagination anyway, but I've imagined all sorts of creepy and painful demises. I can't seem to help it. I've been doing it since high school.

I remember that movie. I did not understand the ending. Something about bad people becoming the robot god of hell inside black holes.
V. poor. But then it is Walt Disney. |

Hey, it netted $10 million. If I could net $10m I would be out producing crappy movies RIGHT NOW.
And "tidal forces" is the correct term to describe the gravity effects on a massive object (such as a body), which, as Stephen Hawking famously said would cause "spaghettification" of anything approaching within a few hundred KM of the event horizon. That's not my term, that's his term and has a wikipedia entry apparently.

Aww, I like that movie (bad science aside.) But then, maybe I'm just nostalgic because it was one of the first sci-fi films I ever saw at the theater. And Maximilian is still my all-time favorite robot. He's the strong silent type. |

| The ending pissed me off. Also, I saw it after star wars (which was awesome when I was a kid, now not so much), and felt very let down by the whole thing. |

As sci-fi cinema goes it pretty much sucked throughout. What was funny was the portrayal of the BH as a blue-ish coloured toilet flush/ aka; whirlpool, in the middle of space. The ending was one of those 'pseudo-religious hell' shot sequences showing the Captain Nemo-type commander trapped in one of his robot guards' outer shell on top of a mountain of molten rock in Hades. Ultra-pathetic cop-out ending to a very contrived and cheesey story. Some knuckle heads swear by it, but they obviously aren't true sci-fi fans (...except Markaba. I myself get a guilty pleasure out of ripened cheese in film). Disney was experimenting at the time with more adult level cinema (cough) and wanted to take advantage of the swelling popularity of sci-fi after Star Wars exploded everyone's preconceptions about sci-fi potential out of the water. They are considering a hard sci-fi reimagining/remake by the same director who is doing Tron: Legacy. I will keep my fingers crossed, but I won't hold my breath. |

| I'm actually looking forward to the Tron remake. Though I am also prepared to be disappointed. |

That takes me back - I don't remember the movie but I do remember the promotional stuff in cereal packets.
Some kind of plasticky thing you coloured in then got mum to put in the oven and it shrank while retaining its shape. Am I imagining things? |

Shrinky dinks, or some such Mr. Bond. They provided Vincent et al to colour in and make your own.
Though that still doesn't excuse the robot hell ending. |

The article confirms my point above: you can pass through the event horizon before being spaghettified if the mass of the black hole is large enough. |
