The Universe Is Continually Expanding After The Big Bang, And We Might Live In A “Hubble Bubble”

There was a time in history when all the galaxies were positioned in the same place and then expanded, a time that we refer to as the Big Bang. Ever since then, it has been demonstrated that the entire solar system, the Earth, and a few thousand galaxies, including Milky Way, are currently expanding. But, we might live in a “Hubble bubble.”

After the Big Bang, the Universe kept on expanding. Edwin Hubble elaborated a theory and a constant to measure the expansion of the Universe.

The Universe is continually expanding

Edwin Hubble was the first to demonstrate this back in 1929, using his own formula, the Hubble Constant (H0), which calculates the Universe’s rate of expansion. However, the problem lies in the fact that there are currently two methods of calculation which seem to give somewhat different results.

Hubble’s method core is the microwave radiation combined with Einstein’s theory of general relativity. In the meantime, the second possibility is based on analyzing the supernovae. These incandescent stars provide the researcher with accurate distances, which has determined an H0 of 74, compared to that of 67.4.

The “Hubble Bubble” theory

Lucas Lombriser, professor of Theoretical Physics in UNIGE Faculty of Sciences, states the fact that the two methods of determining the Universe’s rate of expansion are slightly different from each other. Additionally, he believed that the Universe is less homogeneous than already supposed, this being the reasoning for the differences between the two methods.

The professor adds to the judgment the fact that the Universe might be a massive bubble in order to show that only in this case, the distance of supernovae and the microwave radiation could result in different H0. Therefore, he concludes that the “Hubble bubble” theory is not pure fantasy, and it might have applicability: the Universe has hidden many other regions like ours. It is our duty to reveal them.
