Dark Flow is evidence that our universe is not alone. Yes other Universes' do exist.
Our SINGULARITY, that started the Big Bang came from THE TAIL END OF A SUPER MASSIVE BLACK HOLE FROM ANOTHER PARALLEL UNIVERSE. Black Holes all have an entry point, therefore, they all must have an exit point. A Black Hole is where gravity has gone wild, it breaks down anything and everything that goes into it and then converts it to pure energy. When this Super Massive Black Hole was created in another Universe, the tail end of it was the beginning of ours. The CREATION of the tail of this black hole opening is the start of our Big Bang. This tail end of the black hole is the mouth that keeps blowing matter into our universe. This creates the dark energy and flow which continues to cause our universe to expand. Gravity and radiation turned all the matter in the Black Hole to pure energy, and this is the reason the "singularity" was incredibly hot. And since the Big Bang was an expansion of this heat, and not an explosion, the temperature is uniform. It is the same reason that the contents in a balloon is uniform in temperature. As long as this Black Hole is being fed by the parallel universe, our universe will continue to expand. The same is true when a person blows up a balloon, as long as he keeps blowing, the balloon will expand. This also explains the hard part, "OUR UNIVERSE CAME OUT OF NOTHING". It appears that way, but in reality our universe was created by a Super massive black hole that started in a parallel universe. Energy has just been transformed.
Not all black holes create universes. Just like a person who blows bubbles is unable to successfully blow a bubble each and every time he tries.
The "Big Bang" was not an explosion. It was an instant expansion as the tail end of a Super Massive Black Hole came into existence. This is the reason why this "explosion" has no center point, but yet it has a continuing expansion point from its edge. Since We are in the "balloon", and the source is pushing us and everything else away from it, this will make it difficult for us to see the source. A very small balloon hole can make a HUGE balloon.
Dark Energy is the force that is coming out of the tail end of the black hole that continues to feed our universe... causing our universe to continue expanding...Dark Energy is "the balloon blower" of our universe, and as long as the black hole is consuming, it will continue to blow out matter along with the Dark Energy force.
Thanks for reading my proposed theory, from a person who has probably read one to many Cosmos books, and watched one to many Universe documentaries.
My favorite conclusion to the Big Bang is the Big Rip theory, 1998 New Scientist Magazine, 22 billion years from now what causes red shift destroys the universe like matter falling into a black hole. Slowing the speed of light with time by proportionally increasing the electron rest mass with time so that scientific instruments cannot catch it, favors the Big Rip as gravity eventually does to light what nature has already done to sound.
The 14.1 billion year half life of Th-232 could predate the Big Bang in an 1800's style universe without electrons, where sound travels instead of light through an ether of neutrons. Matter near nuclear reactor critical mass may transmit sound waves faster than light by ignoring the vacuum of space, which is why gold hoarding was used by kings to get astrology and stage magic. By hafnium wall nuclear reactors, elements 72 on up do fission well enough for commercial use, and gold is Au-197-79. Electromagnetism does not apply to nuclear molecules, and has speed of light maximum speed.
Th-232, U-238, Pu-244, and Cm-250 are stabilized as nuclear molecules of He-6 in valence around a denser core. The Sun would substitute nuclear molecules for carbon to fuse hydrogen into helium by quantum mechanical tunneling, alpha particle decay producing the Sun's required helium output. Pressure at the Sun's core would convert some newly formed isotopes to neutron richer isotopes. The half life of U-238 is approximately the age of the Sun, and the half life of Th-232 is the age of the Milky Way, which may also predate the Big Bang.
The minimum mass required to produce a star would drop with time; so stars before the Big Bang could have masses over 100 solar masses to emit sound instead of light; and near the Big Rip, Jupiter and Saturn could fuse hydrogen. Globular clusters would form before the Big Bang like the Milky Way. Sound wave transmission before the Big Bang would slow with time until high vacuums form around massive objects by gravity, gravity so intense that it requires electromagnetic radiation to escape such pits. Matter inside the current black hole at the center of the Milky Way is already past the Big Rip. If neutron stars form cores of dark matter to avoid collapse to a black hole from a white dwarf star, by energy transfer faster than light by a lepton less massive than an electron; then dark matter would sit inside every black hole.
The intermediate vector boson has a 91 GEV rest mass for electron-based matter. Nuclear reactor critical mass behaves like this. A new particle found by CERN has a rest mass of 125 GEV, and it may be the Higgs particle, or it may be the intermediate vector boson for dark matter whose lepton is less massive than the electron.
