What is the Schwarzschild radius of a human?
For a mass as small as a human being, the Schwarzschild radius is of the order of 10-23 cm, much smaller than the nucleus of an atom; for a typical star such as the Sun, it is about 3 km (2 miles).
What is the Schwarzschild radius of the sun?
2.9 km
The Schwarzschild radius of the sun is 2.9 km and of the earth is 0.88 cm.
What is Schwarzschild radius Quora?
Schwarzschild radius is the radius below which the gravitational attraction between particles of a body cause it to undergo gravitational collapse. Schwarzschild showed that any mass can be a black hole if that mass can be compressed into a small sphere of radius R which is called Schwarzschild radius.
What is the radius of the universe?
about 46.5 billion light-years
The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion light-years, or 8.8×1026 metres or 2.89×1027 feet), which equals 880 yottametres.
Is the Schwarzschild radius the same as the event horizon?
Surrounding the black hole is something called the event horizon, the boundary between the black hole and the rest of the universe where the escape velocity is just equal to the speed of light. The distance from the center of a non-rotating black hole to the event horizon is known as the Schwarzschild radius.
What is the radius of a human?
The radius is the thicker and shorter of the two long bones in the forearm. It is located on the lateral side of the forearm parallel to the ulna (in anatomical position with arms hanging at the sides of the body, palms facing forward) between the thumb and the elbow.
