a radius and are not point like this would mean (assuming a quark is spherical and

made of partial electric charges on the surface of the sphere) that the minimum size a quark can become

is given by:

k q^2/ r^2 = 10^ 45

i.e radius of quark = 10^ - 37 metres.

I have not used quantum field theory because I do not think

it applies to forces between the partial charges of a quark sphere.

The minimum radius of the universe at the time of the Big Bang would then be

10^26 x 10^ - 37 = 10 ^ - 11 metres.

(10^26 because I am assuming a density of 1 quark per cubic metre in the

current universe where there are 10^ 78 quarks).

Quarks with a finite radius overcome the problem of a singularity in relativity!
