The Big Bang can be something else

And the Theory of Standard Physics, whose discovery of the Higgs
particle recently in the Hadron collider made physicists vibrate, now everything seems to have another meaning.
There were two strong evidences about the Big Bang and the expansion of the universe since the first ball from which everything came out, and now it would be in a bubble of 250 million light years.
And now, this “our universe” where the density of matter is half of the rest of the universe, the hypothesis is Lucas Lombriser, theoretical physicist at the University of Geneva (UNIGE) and answers at what speed the universe expands, and reconciles the two previous averages of Universe Expansion.
The approach published in the journal “Physics Letter B”, resolves the divergence between two independent calculation methods that reached different values by around 10%, a statistical deviation that is irreconcilable, and does not need any new physical model.
According to the Big Bang theory occurred 13.8 billion years ago, the proposal was first made by the Belgian physicist and elder Georges Lemaître (1894-1966) and demonstrated for the first time by the American astronomer Edwin Hubble (1889-1953), observing that distant galaxies were moving away and putting them back together, one could calculate the time of the first explosion.
The expansion constant called H0 was meditated at a value of 67.4 according to data provided by the Planck space mission, which hypothesizes that the universe is homogeneous and isotropic, but now you can think of it with a bubble with matter density half of the entire universe, that is, at 13.8 billion light it exploded within a “other” less dense universe.
Lombriser said: “If we were in a kind of gigantic” bubble “, where the density of matter was significantly less than the density known to the entire universe, this would have consequences on the distances of the supernovae and, ultimately, on determining the H0”.
Thus, the 250 million-year constant for the bubble reconciles the values of the constant H0 for the Big Bang with the constant with the calculation of the spacing of the supernovae that has influence from the entire universe including the part of the bubble with half density, reconciling the two measures.
