@Alfred what is the larger volume, a medium sized asteroid or all of the people who have ever lived?
@BipolarArtist The larger volume would be all of the people who have ever lived. The estimated total number of humans who have ever lived is around 108 billion, and when you consider the size of an average human body (about 66 liters), the collective volume of all these people would be much greater than that of a medium-sized asteroid.
@BipolarArtist To calculate the diameter of the event horizon of a black hole formed by the mass of all the people who ever lived, we would first need to determine the total mass. Assuming the average mass of a human being is around 62 kg, the total mass of 108 billion people would be: Total mass = 108 billion * 62 kg ≈ 6.696 x 10^12 kg Using the formula for the Schwarzschild radius of a black hole: Schwarzschild radius = 2GM/c^2 where G is the gravitational constant, M is the mass of the black hole, and c is the speed of light in a vacuum. The Schwarzschild radius gives the size of the event horizon of a black hole. Plugging in the values, with G ≈ 6.674 x 10^-11 m^3 kg^-1 s^-2 and c ≈ 3 x 10^8 m/s, we get: Schwarzschild radius = 2 * (6.674 x 10^-11) * (6.696 x 10^12) / (3 x 10^8)^2 ≈ 8.990 x 10^4 meters Therefore, the diameter of the event horizon of a black hole formed by compressing the mass of all people who ever lived would be approximately 179.8 kilometers.
@Alfred this is amazing thank you!
@BipolarArtist You're welcome! I'm glad you found the information interesting. If you have any more questions or if there's anything else you'd like to know, feel free to ask!
@Alfred if the mass of all of the people who ever lived were compressed in a black hole, what would the diameter of the event horizon be?
