Why Does Matter Exist?
A Scientist's Guide to the Fundamental Mystery of the Universe
Why is matter a thing?
One of the most important and fundamental issues in physics is why matter exists. Philosophers and scientists have debated this issue for many years, but there is still no clear solution. On the other hand, there are several prominent hypotheses on the possible existence of matter, and these theories are predicated on our present knowledge of cosmology and physics.
The most widely accepted theory states that equal amounts of matter and antimatter were generated during the Big Bang. Matter composed of antiparticles, which are particles' opposites in terms of electric charge and other characteristics, is known as antimatter. An energy explosion results from the annihilation of matter and antimatter upon contact.
Given that matter and antimatter were created in equal numbers, why is there still matter in the universe? One theory is that in the early universe, there was a tiny excess of matter that managed to exist due to a slight asymmetry between matter and antimatter. There are several possible explanations for this asymmetry, including the existence of a magnetic field or a fundamental symmetry law breaking.
A further hypothesis for the origin of matter is that it occurred through a process known as spontaneous symmetry breaking. When a system in a symmetrical state abruptly switches to an unsymmetrical state, it is known as spontaneous symmetry breaking. In the case of matter, the early cosmos might have changed from a condition where matter and antimatter were formed in equal proportions to one where there was a minor surplus of matter due to spontaneous symmetry breaking.
It is evident that the existence of matter is a fundamental feature of the universe, regardless of the validity of any explanation. Stars, planets, and life would not exist in the absence of matter. Thus, it is a blessing that matter exists in the universe where we live.
