I am not a scientist by training. I have a graduate degree in ancient languages. Is this the right place to ask some basic questions about the Big Bang?

mrblint said:Thanks. I am interested specifically in how "cooling" (I guess that would be energy density decreasing) results in the formation of multiple elements.
Is it correct to assume that "singularity" means "undifferentiated matter|substance"?
If energy density is defined as "energy stored in a given system or region of space per unit volume or mass" then for energy density to decrease, either mass would have to increase or space would have to increase. Is that right?
Is it correct to assume that the mass of the Universe is constant? So that it is space that is increasing?
Did space increase uniformly? Homogeneous energy density? No clumping of mass? Or if energy density did not remain homogeneous, what accounts for the heterogeneity?

1.No.
2. Space is expanding, but not like a tire expands when you put air in it. It is expanding as if the whole tire gets bigger and bigger by itself. Distances between points(events) just get bigger and bigger for no apparent reason.
The Big Bang theory is a scientific explanation for the origin and evolution of the universe. It proposes that the universe began as a singularity, a point of infinite density and temperature, and has been expanding and cooling ever since.
The Big Bang theory was developed through a combination of observations, mathematical models, and experiments by scientists such as Edwin Hubble, Georges Lemaitre, and Alan Guth. It has been refined and supported by evidence from various fields of study, including astronomy, physics, and cosmology.
There are several lines of evidence that support the Big Bang theory, including the observed expansion of the universe, the cosmic microwave background radiation, and the abundance of light elements such as hydrogen and helium. Additionally, the theory can explain the observed distribution and structure of galaxies in the universe.
While the Big Bang theory is the most widely accepted explanation for the origin and evolution of the universe, there are alternative theories such as the Steady State theory and the Oscillating universe theory. However, these theories have not been supported by as much evidence as the Big Bang theory.
The Big Bang theory continues to be an active area of research in the fields of astronomy and cosmology. Scientists are studying the expansion rate of the universe, the properties of dark matter and dark energy, and the possibility of a multiverse. Ongoing research and advancements in technology are helping to further our understanding of the Big Bang and the universe as a whole.
