What would the size of the Earth be if it were a black hole?
For astrophysical black holes, up to 40 percent of the rest mass of the accreted material can be emitted in radiation. This radiation will be absorbed by the outer layers of the Earth and will vaporize them. Examples of this kind of dramatic matter to energy conversion are quasars.
How small would the Earth need to be compressed in order to become a black hole?
If you plug in the mass of the earth, the radius is about 9 mm — which is how small you would have to compress it to make a black-hole.
What would the Schwarzschild radius be if Earth was a black hole?
Any object whose radius is smaller than its Schwarzschild radius is called a black hole….Black hole classification by Schwarzschild radius.
Class | Approx. mass | Approx. radius |
---|---|---|
Intermediate-mass black hole | 103 MSun | 103 km ≈ REarth |
What would happen if Earth was swallowed by a black hole?
Our atmosphere would start to be vacuumed up. And then huge chunks of the Earth would rip apart and follow suit. If Earth managed to fall into the orbit of the black hole, we’d experience tidal heating. The strong uneven gravitational pull on the Earth would continuously deform the planet.
What is the Schwarzschild limit?
The connection is that the Schwarzschild limit says how much you can compress a given mass before no force could oppose gravity, whereas the Chandrasekhar limit says how much mass you need such that the self-gravity, given a long enough time of losing heat, will always contract within the Schwarzschild limit for that …
What is singularity in black hole?
The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn’t really exist. Something has to replace the singularity, but we’re not exactly sure what.
What would happen to Earth’s orbit if the Sun became a black hole?
What would happen to Earth’s orbit if the Sun became a black hole? Nothing would happen to Earth’s orbit IF the Sun became black hole, Nothing would happen to the orbits of the other planets either or the orbits of the planets’ natural satellites, because mass of the Sun would not change.
Do black holes have the same density as the Sun?
Since density is mass divided by volume, and the density needs to be the same for both an Earth-mass black hole and a Sun-mass black hole, the Earth-mass black hole will have less volume (it’ll be smaller). Same density, different volume.
What is the difference between a black hole’s density and Schwarzschild radius?
Density does not apply due to all the value being confined to an enfolding surface tension. Density describes mass per volume. A black hole has no intrinsic mass, and the volume is attributed. The schwarzschild radius is a limit to the use of space.
What would happen if the Earth was swallowed up by a black hole?
The Earth would be destroyed, but the whole planet would not be swallowed up by the black hole. A black hole with a Schwarzschild radius of about a centimeter, which would make it about the size of…
How much angular momentum would it take to make a black hole?
Trying to make a small (two Earth mass) black hole with all of the Earth’s angular momentum would mean that the surface would have to travel at about 10 9 times the speed of light.
