Discussion Overview

The discussion revolves around the conditions necessary for a Schwarzschild radius to form a black hole, particularly in relation to an individual's mass and the implications of energy compression. Participants explore mathematical calculations, physical principles, and hypothetical scenarios regarding black hole formation.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant questions the condition for forming a black hole based on their mass and calculated Schwarzschild radius.
  • Several participants challenge the initial calculations, suggesting that the Schwarzschild radius for the given mass is much smaller than stated.
  • Another participant emphasizes the need for sufficient density to achieve black hole status, implying that mere mass is not enough.
  • A participant provides a detailed calculation of the Schwarzschild radius, indicating it is extremely small for a human mass, suggesting a misunderstanding of the concept by the original poster.
  • There is a mention of the requirement to compress energy within the Schwarzschild radius to actually become a black hole, adding another layer to the discussion.

Areas of Agreement / Disagreement

Participants generally disagree on the accuracy of the initial calculations and the conditions for becoming a black hole. Multiple competing views remain regarding the necessary conditions and the implications of density and energy compression.

Contextual Notes

Limitations include potential misunderstandings of the Schwarzschild radius and the conditions under which a mass can become a black hole. The discussion does not resolve these mathematical or conceptual uncertainties.

What is the condition for the schwarzschild radius to form a black hole?
Well, for example I have 65 Kg, so my Schwarzschild radius is 9.62x10^26 m
Why am I not a black hole?

You might want to check your math.
 
you are not dense enough.
 
Check out the link below concerning a certain fictional "human black hole."

Your math is wrong. Your Schwarzschild radius should be extremely small. You would be a black hole only after all your mass was squeezed into that radius.
 
I think you should check your maths.

Schwarschild radius: [tex]r_{s}[/tex]=[tex]2Gm\overline{c^{2}}[/tex]

substitute the following values:

[tex]r_{s}[/tex] is the Schwarzschild radius (you want to calculate)

[tex]G\ =\ 6.673(10)\ \times\ 10^{-11}\ m^{3} kg^{-1} s^{-2}[/tex]

m is your mass, assume = 70 Kg

[tex]c\ =\ 2.99792458\ \times\ 10^{8}\ m\ s^{-1}[/tex]

hence [tex]r_{s}[/tex]= 1.0394599353664114117056783269603e-25 m

meaning your radius should be approximately as small as one part in ten million million million million of a meter!

You will certainly become a black hole if you compress yourself upto Schwarzschild radius. As said earlier your math is wrong. But one condition is again missing. To be a black hole you should compress the energy of your body within the region of Schwarzschild radius.
