SUMMARY

The discussion centers on the visual perception of a black hole from behind the event horizon. Participants describe the spatial appearance of a black hole as akin to a heavy object on a taut sheet, distorting space-time. Observers positioned on the singularity side ponder whether they would see an event horizon, a dot, or if the black hole is entirely unobservable. A link to a resource detailing the experience of falling into a black hole is provided for further exploration.

PREREQUISITES
  • Understanding of general relativity and its implications on space-time.
  • Familiarity with black hole terminology, including event horizon and singularity.
  • Basic knowledge of gravitational lensing and its effects on light.
  • Awareness of visual representation tools in astrophysics, such as simulations or diagrams.
NEXT STEPS
  • Research gravitational lensing and its impact on the appearance of black holes.
  • Explore visual simulations of black holes using software like Blender or MATLAB.
  • Study the physics of singularities and their observable characteristics.
  • Investigate resources on the experience of falling into a black hole, such as the link provided in the discussion.
USEFUL FOR

Astronomy enthusiasts, astrophysicists, and educators seeking to understand the visual and theoretical aspects of black holes.

Hi guys, can't find a post similar to this so ill ask;

What does a black hole look like from behind? The spatial apperance is similar to a heavy object sitting on a taught towel or sheet (due to its large mass affecting space-time), but what does an observer on the singularity side (further from the event horizon) see? Does it appear to have an event horizon (black cirlce surrounded by blurred matter circles) on the back side, does it appear as a dot (viewing the singularity from behind) or is it not observable? Surely all 3 dimensional objects have a back and front to go with their other 2 dimension hence making it observable?

Thoughts?

Thanks!

I know there is an example somewhere of what it looks like to fall into a black hole. I just don't remember where. Perhaps someone knows the link.
