Big Bang Cosmology

SAGREDO: Question about the scientific view on the origin and evolution of the universe

Scientists that explore questions about the origin and evolution of the universe (aka cosmologists) have developed a cosmology based on theoretical developments of the past 80 or so years and very impressive experimental results from only few years ago. This theory of the origin and evolution of the universe, so called “the standard cosmological model” claims that we know what the universe is made of and to a large extent (except for the very first few fractions of a second) everything that happens in the universe can be explained by science. Some popularizes of science are asking the public to accept this model of the universe in the grounds that the evidence is overwhelming and very unlikely to be disproved [1]. However, many examples can be cited where scientists have made similar claims only to be withdrawn at the next experiment contradicting the claim. Despite the exuberance of scientists working in the field and at times overreaching conclusions, it does appear that new observations are solid, repeatable, and highly coherent (to the point that the most acerbic critics have conceded [2]). Question: Does experimental and observational evidence grants the scientific view of cosmology a platform to claim validity?
