Rhis new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror. The visualization simulates the appearance of a black hole where infalling matter has collected into a thin, hot structure called an accretion disk. The black hole’s extreme gravity skews light emitted by different regions of the disk, producing the misshapen appearance.
Bright knots constantly form and dissipate in the disk as magnetic fields wind and twist through the churning gas. Nearest the black hole, the gas orbits at close to the speed of light, while the outer portions spin a bit more slowly. This difference stretches and shears the bright knots, producing light and dark lanes in the disk.
Looks like the math-artists got it right on Interstellar.

Want to build your own website? Even for a modest personal site, it was once assumed you might wait for days or weeks while a web designer hammered through arcane code on your behalf. That all sounds a little ridiculous today. And if you had to thank one company for that, it would probably be […]
