US, WASHINGTON (NEWS OBSERVATORY) — Lucas Lombriser, a physicist at the University of Geneva, noted that measuring the Hubble constant with various proven methods has deviations of 10%. Such a difference in data is unacceptable.
Back in school, everyone was told that the Universe has been expanding for 13.8 billion years (since the Big Bang).
This was confirmed by Georges Lemaitre, a Belgian physicist, and a little later, in 1929, Edwin Hubble, an astronomer from the United States.
The latter clearly showed how the galaxies are gradually moving away from us.
The Hubble study became the basis for the introduction of the Hubble-Lemaitre law and the Hubble constant (H0), which indicates the speed of expansion of outer space. Now the speed of distance of objects is 70 (km / s) / Mpc.
The indicator suggests that the expansion occurs at 70 km per second every 3.26 million light years. The calculation of the indicator is made by several not quite similar methods, which often produce conflicting data.
For decades, scientists have argued over what information to believe. Looks like Lucas Lombriser closed the question forever. So, in his opinion, the entire Solar system, our galaxy and the nearest galaxies move in a certain “bubble”, the diameter of which is 250 million light years. In this ball, the density of matter is several times lower than in space as a whole.
This information will help calculate the new value of the Hubble constant, which will take into account the cosmic microwave background.
