Relativistic star
Shouldn't this article include a hypothetical star of ultra relativistic material which might exist in a black hole? Should the article link to a Quark star?

If the pressure P of ultra relativistic material is given as (rho)(c^2)/3, the total supporting energy of this star would be ∫PdV = (Mc^2)/3, meaning a whopping 1/3 of the mass energy of the star would be used just to oppose the force of gravity. Interestingly, using the viral equation, if (Mc^2)/3 is equal to 1/2 the gravitational binding energy of 1.1G(M^2)/2R, the radius R of this star equals 1.65GM/(c^2), or 0.82 of the Schwarzschild radius. 172.162.5.253 (talk) 08:06, 13 November 2013 (UTC)BG
