Universe mysteries and universal forces

25 Nov

When Einstein formulated the Theory of General Relativity, two big “holes” remained in his theory, one he recognized as wormholes, paths in a space-time dimension in which there could be spaces, from a mathematical point of view, of immense gravity in which everything “disappeared” and another unrecognized one was the formulation of quanta as a dimension between time and space where there is a third hypothesis between matter and non-matter, the “quanta”.

According to physicist Jim Al-Khalili “He devised a new theory about the entire Universe, in which he also said that when stars collapse they form black holes”, and that at that time he believed they were just mathematical hypotheses, necessary to close the account, but “that they didn’t exist, that they were just products of mathematics”, but it was something that bothered him said Al-Khalili in the BBC interview.

The quantum issue was a state called entanglement, today called quantum entanglement, a state of the particle where there was a collapse of the wave function, and thus, the actual existence of the particle was in an “adjacent” reality which is precisely the entanglement, Einstein, Poldoski and Rosen wrote an article that by their names was called EPR in which they said that the particle was always present and rejected the hypothesis of a “third state”, which was later proved.

Black holes not only exist, but pictures have already been taken (a famous one was published in April 2019), which are actually made by algorithms that map the magnetic effects around it, and thus build an image, it is now known that they are numerous and even some exist within our galaxy, the Milky Way.

Universal forces are increasingly arousing curiosity and also fear, a large comet was recently discovered and was named after the Brazilian Bernardinelli who were doing a doctorate in cosmology in the US, called Bernardinelli-Bernstein (C/2014-UN271) 150 km in diameter and can be seen in 2031, but they are the meteors that populate the imagination of the apocalyptic on duty, they are numerous and unpredictable, some are discovered moments before passing close to our planet.

NASA started a test mission in an attempt to redirect asteroids, the project called Dart (Double Asteroid Redirect Test) will try to send a small spacecraft to collide against Dimorphos, “moon” of the asteroid Didymos, in an attempt to change its route, does not represent danger to the planet, so this is just a test.

The universe is mysterious, we still know little about it, 68% is made of dark energy (picture), and this energy does not dilute as the universe expands (the entropy principle), and if this expansion is faster and faster, as Einstein supposed, this can lead to some curious conclusions, such as the fact that this strange “energy” arises in this expansion.

Look at the Universe and its mysteries should restore us to the humility of how little we know, how admirable is the mystery of life and our destiny as a person and as a planet.
