Pseudoscience includes a lot of things if you take pieces of the bigger puzzle and evaluate them individually. In this case the bigger puzzle is Big Bang Theory with Inflation that is not abandoned but is modified as old and new puzzle pieces fit into place. BBT will continue to be the standard until some new and better cosmology gains acceptance.
The next “standard” cosmology will simply put the same puzzle pieces together in a way that improves the fit of the interlocking pieces with maybe a single new piece being the turning point. Whether that new piece comes from string theory, inflation theory, quantum mechanics, or some old idea like steady state or some combination of ideas that fit in a new way, the puzzle will slowly be put together in a new way based on new insight.
What won’t happen is that the old standard will immediately be forgotten and the new standard universally accepted. It will take decades for a new and “enlightened” generation to gain the consensus. And I put enlightened in quotes because the final answer is probably unknowable. Still our inquisitive minds will never stop searching, so the standard cosmology will continue to evolve and will always be the current “enlightenment” to which the clan of the cave bears points to as the final answer.
Two contributors to the slow rate of change in the consensus in spite of the rapid rate of new and better knowledge are ego and investment. Ego of everyone who thinks that they truly understand; I included. And investment of two kinds, one of rigor to arrive at our place of knowledge which we often value more that common sense, and the other is investment in resources to advance knowledge which can’t always be turning on a dime.
Quit being offended, quit the ego trip, quit obstructing progress and just accept what I tell you; these are the ultimate “ain’t never gonna happen” scenarios.
