In the Doctor Who episode The Impossible Planet, the Doctor and Rose find themselves on a planet that is emitting a "gravity beam" while orbiting a black hole.



This is a screenshot from the episode. When Rose and the Doctor see the black hole, the Doctor cries out, "That's impossible!" He claims that a lot of things are impossible in this episode, including the fact that the planet is orbiting around a black hole. As they stood in their ship, they witnessed stars zooming by them and being sucked into the so-called black hole.

About five minutes and a dozen "impossibles," Jerry turned to Me and remarked, "He keeps on using that word. I do not think it means what he thinks it means." I wasn't going to even touch the "gravity beam" nonsense, but I exploded.

"Your science is WRONG!!" I yelled at the television. "That's not what a black hole looks like! That's a gorram solar eclipse! A black hole looks like nothingness -- we cannot see it, because, duh, it's a black hole. We might know it's there if there's something orbiting around it or see a trail of light if a cloud of dust is being pulled into it, but not if it's just there. Which brings Me to My next point. A black hole cannot swallow up an entire solar system, just like that. A black hole is small, maybe the size of a planet. It can't just arbitrarily swallow stars from light years away. If it could, we'd have not universe left. The entire Milky Way Galaxy is thought to be orbiting around a black hole! Get off it, Doctor. This brings Me to My final point. IT IS PERFECTLY POSSIBLE FOR A PLANET TO ORBIT AROUND A BLACK HOLE. Let's say a planet was orbiting around a large star, and that star was to collapse and become a black hole. Gravitational attraction is determined by Mass divided by distance [from center of gravity] squared. Now, when a star becomes a black hole, what changes? Not the mass, but the size and density. What about the distance? Does the center of gravity move? NO! These two factors [distance and mass] stay constant! The gravitational attraction, and therefore the orbit, of a nearby planet, would NOT BE AFFECTED AT ALL!" I paused for breath, red in the face and gasping for air. "Your science is WRONG. Good day, Sir!"

At this point in time Jerry decided to respond. "Anastasia," he said slowly, looking at Me over the rims of imaginary glasses, "they are in a time traveling phone booth. Suspension of disbelief, Motherf*cker, DO YOU SPEAK IT!?"

I stand by My previous points.
