The above process keeps the # of protons and the # of neutrons in the early Universe constant. This is extremely important and will result in a testable prediction later. Remember, a free neutron (one that is not bound in an atomic nucleus) will decay into a proton + electron (+ anti-neutrino) in about 900 seconds. ... During this epoch, the proton-to-neutron ratio is 1.0 . ... The Universe consists of protons, neutrons and electrons plus a photon background and a neutrino background. ...

. To remove a directory that is a symbolic link that points to another directory use the command: rm directory_name . Notice that the directory does not need to be empty and you do not have to use the rmdir command. You are not really removing a directory, just a named symbolic link that points to the "real" directory.

... Although they all formed from similar material, it is a mystery why the planets closest to the Sun Mercury, Venus and Earth are so different. Astronomers hope to learn more about how they were created by studying asteroids, which are pieces of rock that were surplus to requirements in planet building.

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
