Theoretical cosmology is the study of the constituents and evolution of our Universe as a whole, from the earliest stages to the present day.
It involves building consistent theoretical models and testing their validity using data from experiments and observations..
The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded.
Most astronomers use the Big Bang theory to explain how the universe began.
But what caused this explosion in the first place is still a mystery..
A Study on the Theories of Development of the Universe has helped us discover these theories until this day: Flat earth theory, geocentric model, heliocentric model, and the Big Bang Theory.
With the advancement of science and technology, every other story brought us closer to the answer to how this universe was made..
The flat Earth, the geocentric model, heliocentricity, galacticocentricity, the Big Bang, the Inflationary Big Bang… Each model explains what was known at the time and what the measurements could confirm.
We cannot say that these theories were wrong; perhaps it would be truer to say they were incomplete..
This cosmology principle of homogeneity and isotropy is theorized to result from a model of the evolution of the universe known as the Big Bang.
The theory asserts that the universe evolved from a highly dense, point-like state and expanded into its currently observed low-density, isotropic, and homogeneous state.Jun 14, 2023.
Various cosmological theories, including the Big Bang theory, the Steady State theory, inflation, and dark matter and dark energy models, have been devised to solve several problems the universe poses.Jun 14, 2023.
