Black Hole Makes Material Wobble Around It




The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole. The discovery, aided by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, solves a mystery that has eluded astronomers for more than 30 years, and will allow them to map the behavior of matter very close to black holes. It could also open the door to future investigations of Albert Einstein's general relativity.

the way things rotate or spiral is interesting. Does the DNA of all life on this planet rotate in the same direction?

Although DNA might rotate while being unzipped for reproduction, it doesn't do so otherwise. Not sure how much this has been studied.

I've heard other wise from the beginning. It's a double helix.

There was an alien TV show that talked about this and that if aliens showed up with DNA that spiraled in the opposite direction we wouldn't have to worry about swapping diseases.

Ah, I see they're just talking about the direction in which the helix forms, not a spin as in a planet spinning on it's axis. It really would be interesting to see if the DNA of all lifeforms on this planet have this same formation or not.

That would be a good thing.
