Is there an orthodox scientific view on the origin of matter or is this invariably considered to be a metaphysical question?

Not so fast! There are a number of people - including several PF members - who can give you good reasons to think that it is a question which science may be able to answer (but not just yet). If you look at the Strings section of Physics you'll see much discussion of two possibles; the Astronomy & Cosmology section also has much discussion.Canute: I know that this is not a question science can answer, but I wondered if there was any consensus on what kind of answer it might have. I assume not, but am still checking.
The Big Bang theory is the most widely accepted scientific explanation for the origin of matter. It proposes that the universe began as a singularity, a point of infinite density and temperature, about 13.8 billion years ago. This singularity then rapidly expanded in a massive explosion, creating all the matter and energy in the universe.
After the Big Bang, the universe was filled with a hot, dense plasma consisting of particles like protons, neutrons, and electrons. As the universe expanded and cooled, these particles began to come together to form atoms. Through nuclear fusion in stars and supernova explosions, heavier elements were formed, leading to the creation of the diverse matter we see in the universe today.
There are several lines of evidence that support the Big Bang theory and the origin of matter. This includes the observation of the cosmic microwave background radiation, the abundance of light elements in the universe, and the redshift of galaxies, which is evidence of the expansion of the universe.
While the Big Bang theory is the most widely accepted explanation for the origin of matter, there are some alternative theories, such as the Steady State theory and the Oscillating Universe theory. However, these theories have been largely disproven by observational evidence and are not widely accepted by the scientific community.
The origin of matter is a crucial part of understanding the history and fate of the universe. It not only explains how the universe began, but also how it has evolved over time and how it will continue to change in the future. The study of the origin of matter is closely linked to other areas of cosmology, such as the study of dark matter and dark energy, which play a role in the overall fate of the universe.
