How far is the closest star?

"Pressure inside the proton

Since the proton is composed of quarks confined by gluons, an equivalent pressure which acts on the quarks can be defined. This allows calculation of their distribution as a function of distance from the centre using Compton scattering of high-energy electrons (DVCS, for deeply virtual Compton scattering). The pressure is maximum at the centre, about 1035 Pa which is greater than the pressure inside a neutron star.[42]. It is positive (repulsive) to a radial distance of about 0.6 fm, negative (attractive) at greater distances, and very weak beyond about 2 fm. "

Proton

Strong Nuclear force will be shown to warp the geometry of space time hundreds of times more than the strongest gravity in the universe just compressed into a very small area.

Radius of a Proton .877X10^-15 meters

Mass of a Proton = 1.2672X10^-27 kG or 938 MeV/c^2

Schwartzchild Radius for the Mass of Proton (Kg) = 1.7676665X10^-32

Plank Length = 1.6X10^-35
