Quasi-steady-state cosmology (QSSC) is a cosmological model proposed as an alternative to the Big Bang theory. It suggests that the universe is in a state of continuous creation, with matter being created at a constant rate to maintain a steady density.
Unlike the Big Bang theory, which proposes a single event of rapid expansion and cooling of the universe, QSSC suggests that the universe has always existed and is continuously expanding at a constant rate. It also does not rely on the concept of a singularity or initial point of creation.
Currently, there is no conclusive evidence that supports QSSC. Some proponents of the theory point to the observed distribution of galaxies and the cosmic microwave background radiation as potential evidence. However, these observations can also be explained by the Big Bang theory.
One of the main criticisms of QSSC is that it does not explain the observed redshift of distant galaxies, which is a key piece of evidence for the Big Bang theory. Additionally, QSSC does not account for the abundance of light elements in the universe, which is another key aspect of the Big Bang theory.
No, QSSC is not widely accepted in the scientific community. The majority of scientists and cosmologists support the Big Bang theory, as it is backed by a significant amount of evidence from various fields of study. QSSC is considered a fringe theory and has not gained widespread acceptance.
