Current cosmology is a worldview

02 Apr

Current cosmology is one that considers the universe as having a beginning, which may be a multiverse or a bubble, and that expands in a constant between Hubble’s H0 and the rates measured from the supernovae, whose reconciliation may be the new theory of universe in a bubble launched by Lucas Lombriser whose article appeared in this month’s Physics B magazine.
But this cosmology considers the mystery of the energy and dark matter that makes up 96% of the unknown universe and this puzzle modifies cosmology and also our worldview.
This cosmology postulates the idea that this dark matter does not interact with ordinary matter and the hypothesis something that “swallows” all known matter (called baryonic around it, including light) evolves to the idea that it has a high mass density and collapse of supernovae and their gravitational interaction has an effect on visible matter, stars, galaxies and clusters.
Of what it is made, it is certain that it does not have matter like the now stable model called Standard Physics, which we explored in the previous post, so it goes beyond this model and one of the most interesting theories is that of supersymmetry, which explores the concept of standard physics that each particle has a symmetric, just like bosons and fermions,
What this theory about dark matter proposes is that for every known boson there is an unknown fermion and vice versa, but there is a difference with the theory of antimatter, because antiparticles have opposite charges but the same mass and when they come into contact they produce energy, which would also explain dark energy.
Fermions as well as protons, electrons and neutrons, make up our material world and bosons are the ones that generate the forces of nature, the discovery of the Higgs boson or “God particle” was important because it made us understand the mass, while fermions explain the quantum state because two fermions occupy the same quantum state.
The fact of the existence of dark energy, more interesting than its mystery and presence in 70% of the universe (25% is dark energy) in addition to our ignorance is the fact that it is this “matter” that gives us a complete worldview of our universe , not only because it is dark because it is not visible, but also unknown.
James Gilles’ TED below, seen by more than 2 million people, explains the dark matter theory.
