NASA Black Hole Visualisation

SUMMARY

The NASA Black Hole Visualization, created by NASA's Goddard Space Flight Center, effectively demonstrates the warping of space-time around a black hole. Users expressed curiosity about the visibility of the blueshift effect, particularly when crossing the event horizon, which is noted to exceed 43 times the normal frequency. The discussion highlights that while the simulation captures the geometry of the background sky, it may not visually represent the expected color changes due to blueshift, leading to questions about the accuracy of the visual feedback provided.

PREREQUISITES
  • Understanding of general relativity and its implications on light behavior around massive objects.
  • Familiarity with black hole physics, specifically event horizons and blueshift phenomena.
  • Knowledge of computer graphics and simulation techniques used in scientific visualizations.
  • Basic principles of light frequency and color perception in astrophysics.
NEXT STEPS
  • Research the principles of general relativity and their application in black hole physics.
  • Explore advanced visualization techniques used in astrophysics simulations.
  • Learn about the effects of gravitational blueshift and redshift on light near massive objects.
  • Investigate NASA's scientific visualization tools and methodologies for creating accurate representations of astronomical phenomena.
USEFUL FOR

Astronomers, astrophysicists, educators, and anyone interested in the visualization of complex astronomical phenomena and the effects of gravity on light.

I was expecting to see the background light being blueshifted enough to be visibly changing color. Is the effect just not visible in the simulation or is my expectation wrong? In the case of crossing the event horizon the caption mentions a blueshift in excess of 43 but how is that visible? Perhaps they left out the effect to allow people get a visual feedback on how the "geometry" of the background sky is warped?

Anyone?
 
Should definitely see blueshift from in front (so long as not obscured by the black hole shadow...). I don't know how they've incorporated this into the visualizations.
