other, this meant that the universe was expanding. Hubble found
the movement of the galaxies by using a phenomenon known as the Doppler effect.
This effect caused bodies moving away from an observer to have a "red-shifted"
spectrum (the light spectrum of the body had been shifted closer to red) and
bodies moving towards an observer to be "blue-shifted" (Hawking, 1988)
The expansion was traced backwards through time to discover that all the
galaxies had originated from the same point. It was later believed that all
matter spawn from that "center of the universe" discovered by Hubble, by means
of some sort of enigmatic portal. Matter would collect outside this singularity
and form every moon, planet, and star known today.
The Steady State Theory was very attractive because it featured a
universe with no beginning or end. The theory meant that scientist had to
abandon the laws of conservations of mass and energy. It seemed plausible that
the aforementioned laws of physics could ...

protons and neutrons. The protons and neutron are, in this very dense soup,
participating in sub-atomic reactions. The two most important of these
reactions are:
Antineutrino + Proton ----> Positron (anti-electron) + Neutron
Neutrino + Neutron ----> Electron + Proton In effect the protons are
becoming neutrons and vice-versa. The energies are so great that simple atoms
being formed fall apart immediately after coming together. (Silk, 1994)
As the universe expands, and loses energy the electrons and positrons
begin to collide, effectively annihilating one another, leaving only energy in
the form of photons and neutrinos. Appropriately fourteen seconds after the Big
Bang ...
