There are many mysteries that are hidden in the depths of the universe. The dough, Energy either matterdark it makes it hard for scientists to gauge just how big the size of the vast land of which we are a part is. But there is something that is not in dispute: this is expanding by every passing second.
What is discussed in the upper echelons of science is the speed at which it occurs. For more than 100 years there have been studies, analyzes and constants that have become “bibles” for those who approach the study of the cosmos.
For this reason, if there is information that refutes what has been written by those brilliant minds, it is necessary to have accurate data that demonstrates the reality that they are appreciating in the tools with which the depths of the universe are studied.
The most recent features an estimate made in a Nobel Prize study adam riess. In a very general concept, the team led by this scientist determined that a star distant from Earth at 1 megaparsec (more than 3 million light years) recedes 73 kilometers per second.
While one that is twice our distance, that is, approximately 6.5 million light years, shows that the massive star It moves away at 146 kilometers per second, that is, twice as fast.
This is much faster than the Planck constant posits. But we’ll get to that part and what differentiates each of the measurements.

Is the star really moving away from us in the universe?
A brilliant explanation of Ruth Lazkozprofessor of theoretical physics at the University of the Basque Country, in The Conversation, says the distance between galaxies increases because the universe expands. In this way, each of the celestial bodies remains in its same position, but as the terrain grew, the distances between the two are no longer the same.
In his explanation, with the intention that we all understand what happens with the expansion of the universe exemplifies the situation with the way in which a food is cooked or baked. Panettone with raisins
“Imagine the raw dough of a panettone, which contains raisins separated from each other. The heat of the oven makes the dough grow, forcing the raisins to separate from each other (and from each other). But, hey! their size does not change. It only remains to think that panettone is space-time and raisins are galaxies. As our pannetone expands, the raisins do not move from their initial position in the dough. Those that have changed have been the relative distances between some raisins and others. By dividing the flaring by the baking time we achieve the speed of our raisins,” she maintained.
The estimation of the Nobel Prize winner Adam Riess is refuted by Planck’s constant, who in his equations estimates that the universe is expanding at a speed of 67 km/s/Mpc.
According to what Professor Lazkoz herself explains, Planck maintains that it is necessary to add the influence of dark matter on the speed of the expansion and the way in which the before influences the now.
That is, to observe the complete journey of the light that we receive from a star in order to determine all the elements present in that journey and thus identify if there could be an error in the measurements. This Planck constant says that, carrying out all this process, it determines that the expansion speed of the universe is of those 67 kilometers per second that we mentioned.
