What is the Schwarzschild radius of a proton?
For comparison, the Schwarzschild radius of a proton is 2.4 × 10−52 cm and that of a typical galaxy of mas ∼ 1045 g is ∼ 1017 cm.
How big would a black hole be with the mass of the Earth?
After just a few minutes more — 21 to 22 minutes total — the entire mass of the Earth would have collapsed into a black hole just 1.75 centimeters (0.69”) in diameter: the inevitable result of an Earth’s mass worth of material collapsing into a black hole. When matter collapses, it can inevitably form a black hole.
What would happen if mass were continually added to a 2.8 solar mass neutron star?
What would happen if mass were continually added to a 2-M! neutron star? The star would eventually become a black hole.
What would happen if more mass was added to a 3 solar mass neutron star?
The star would eventually become a black hole if it exceeded 3 solar masses. the unseen companion in the system must have a sufficiently high mass. Two important properties of young neutron stars are. extremely rapid rotation and a strong magnetic field.
Is it possible to make a black hole?
To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light. In such scenarios, black hole production could possibly be an important and observable effect at the Large Hadron Collider (LHC).

How do you calculate the mass of a sphere?
To calculate the mass of a sphere, start by finding the sphere’s volume using the formula: V = 4 over 3 × πr cubed, where r is the radius of the sphere. Once you have the volume, look up the density for the material the sphere is made out of and convert the density so the units are the same in both the density and volume.
Why are electrons shaped like spheres?
The reason for this assumption is that a sphere is the ‘purest’ of 3D shapes and makes an electron’s field appear identical in all directions. Now the hard part is finding its radius. Before going further some points need to be made about something called the ‘classical electron radius’.
What is the radius of a sphere?
The radius of a sphere is the measure from the center of the sphere to the outer edge. If you are given a problem to calculate volume, you will probably be given the radius. Otherwise, the radius can be difficult to measure because you cannot accurately reach the center of a solid object.
How do you calculate the radius of an electron?
A more realistic approach would be to take the ratio of proton/electron mass, then divide the proton’s radius by the cube root of this number (because mass increases according to the cube of radius). This ratio, 1836, would set the electron’s radius at approximately 12 times smaller than a proton: at 9.1×10 -17 m.
