Expansion of the universe: "Simple theory" solves the contradiction in Hubble's constant

Expansion of the universe: “Simple theory” solves the contradiction in Hubble’s constant

Our universe is much more open and hotter than previously thought, while the density of matter is significantly lower when we are in a kind of bubble. Two Swiss physicists determined this to solve the mystery of the conflict in the Hubble constant.

In addition, the University of Geneva explains that their calculations will solve more contradictions and that new physics is no longer needed. It presents the recent arguments of Benjamin Bose and Lucas Lombraser, which supports their model, which has been in operation for some time. Their study was published in the journal D of Physics Review.

Two researchers compared their model to Hubble’s constant (h.0) Dissolves. This is the basic measure of understanding the universe. This refers to the rate at which the universe is currently expanding, summarizing the rate at which an object moves away from us at a distance of one megaparsec (3.26 million light years) due to the expansion of the universe. For comparison: the Andromeda Galaxy is about 0.89 megaparches away from us. Measurements of relatively close objects in the universe consistently provide a value of 74 km / s / mb, while analyzing cosmic background radiation (CMP) with the Blanc Space Telescope, 9 percent less (67 km / s / mb) .

Last year, the solution to the Lombraser puzzle was to find ourselves in a kind of gigantic bubble that is less dense than the average of the universe. Further analysis has now confirmed this, He explains now. So far, cosmic background radiation has been considered a constant temperature since the time when light first moved freely in the young universe (approximately 370,000 years after the Big Bang). But if you do not make any assumptions for this – as well as for the curvature of the universe – the values ​​measured precisely here deviate from the cosmic average due to this bubble, and then all come together, the two promise you.

Once these two assumptions are removed from the equations, the discrepancy in the Hubble constant is not resolved. Other contradictions in cosmological research can be erased in this way, Write pose and lampreier. Accordingly, there are discrepancies between the average density of the universe, temperature differences in the universe, and the paths through which cosmic background radiation traveled us. These all arise accordingly when the density of our universe (about 10 to 100 megaparsecs) is less than 20 percent of the average of the entire universe. It comes down to absolutely possible differences.
