Once the collapse process has started and the density of hydrogen atoms of the cloud has risen significantly, the fragmentation into smaller cloudlets will take place. And, subsequently, these cloudlets eventually collapse to form individual stars. Therefore, the theory of uh...gravitational condensati...
How many astronomical units is the Oort cloud from the sun? What is the Sun's declination on the fall equinox? How many light years are in an astronomical unit? What is the declination of the Sun at the equinoxes? What is the average density of the sun?
Before, because of the energy density of space, virtual particles formed around the event horizon and led to Hawking radiation, which theoretically leads to black hole evaporation (Brown). Haramein Model of Black Holes Another interesting avenue with our quantum vacuum comes in with the Haramein ...
