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.
