Audio question about black hole

Click For Summary

Discussion Overview

The discussion revolves around the nature of light paths in relation to black holes, particularly focusing on an image and audio file purportedly representing a black hole. Participants explore the implications of light paths within the event horizon and the validity of the audio representation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks clarification on whether the light paths depicted in an image relate to the warped paths of light within a black hole's event horizon.
  • Another participant argues that audio or video labeled as "black hole" may not accurately represent black holes and suggests ignoring such media.
  • A participant explains that the appearance of light paths can vary significantly based on the coordinate system used, mentioning Kruskal and Schwarzschild coordinates as examples.
  • The same participant notes that understanding the coordinate system is crucial for interpreting the behavior of light near a black hole.
  • A later reply expresses curiosity about the audio files and mentions additional videos and a 3D spectrum related to the topic.

Areas of Agreement / Disagreement

Participants express differing views on the validity of the audio and visual representations of black holes, with some skepticism about their accuracy. The discussion about light paths remains unresolved, with multiple perspectives on how to interpret them based on different coordinate systems.

Contextual Notes

Participants highlight the importance of coordinate systems in understanding light paths, indicating that interpretations may depend on the chosen framework. There is also an acknowledgment of potential confusion regarding the media representations of black holes.

Who May Find This Useful

This discussion may be of interest to those exploring the theoretical aspects of black holes, particularly in relation to light behavior and the interpretation of scientific media.

I was wondering if someone can help explain to me what is happening in the image.
Black holes have Light paths or something

so i read here more accurate description is that within this horizon, all lightlike paths (paths that light could take) and hence all paths in the forward light cones of particles within the horizon, are warped so as to fall farther into the hole

I was wondering in this image if that is what the lightpaths are

this is a Mp3 file of a black hole

Well, if someone uploads video/mp3 like this on youtube, and names it "blackhole", it doesn't mean it has anything to do with a black hole. You can safely ignore both, the audio and the visual part of this video.

The lightpaths (and the paths of infalling objects) can look like pretty much anything, depending on what coordinates you are using. Thus, the first step has to be to label your coordinate axes: what does it mean to have a line moving upwards in the diagram? What does it mean to have a line moving to the right in the diagram?

If we use Kruskal coordinates, the lightpaths are straight lines at a 45-degree angle to the vertical (and understanding what a Kruskal diagram is showing you is one of the best ways of understanding what's really going on around the event horizon). If we use Schwarzschild coordinates, the path of a flash of light moving towards the black hole from outside starts as (almost) a 45 degree line that bends upwards so that it he's closer and closer to the event horizon but never gets there: the path of a light starting inside the event horizon is always slanted sideways pointing away from the vertical line representing the horizon and towards the vertical line representing the singularity at ##t=0##.
 
Thanks Nugatory I shall look into that. Although Probably won't understand much. I am still highly curious about so said files

well i got few more videos


also a 3d spectra of it
