At the intense gravitational field strength of a white dwarf star approaching the Chandrasekhar limit all matter is in a degenerate state with the electrons forced into the closest possible orbits outside the nucleus. When the limit is reached the electrons are forced into the nucleus turning everything in the atom into neutrons. This collection of neutrons collapses into a solid neutron star and releases the same amount of gravitational collapse energy regardless of what the previous matter make up of the 2 stars involved were.

Yes, these apertures are tinier than even the 2.0 proposal, but synthetic aperture software can do wonders, and software has great growth potential. Don’t let perfection be the enemy of the good, and the doable!

Why would stars of any type be different?
