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. ...

... The solar wind streams off of the Sun at a speed of several hundred km/s, creating a magnetized bubble of hot plasma around the Sun. This bubble is called the heliosphere, and it is separated from the interstellar gas (local interstellar medium, LISM) by a heliopause. ... The heliopause is believed to be at least 120 AU away from the Sun, i.e., all the planets are located within it ( Earth and Pluto are 1 and 40 AU away, respectively). ...
