Minimum Viable Cosmology - 8

Time to rethink the λCDM model

The previous posting ended with the question: Is the universe so vast and complex that the human mind could never fully understand it? Let us consider the scope of this question more thoroughly.

We have Anil Seth's concept (see MVC-5) of living in a controlled hallucination. This offers a fresh and thought-provoking perspective on perception and consciousness. By challenging the notion of a direct and objective reality, Seth's work encourages us to explore the intricate relationship between our brain, our senses, and our conscious experiences.

Then there are the  problems of communicating such ideas as expounded by Wittgenstein (see MVC-6) —The message there being that communication of the abstract concepts as in cosmology are difficult unless you have a clear picture in your own mind and make it clear to that of the another person by every means possible.

Finally we enter the world of chaos and complexity and self-organisation as presented by Professor Jim Al-Khalili (see MVC-7). The world in which cause and effect are not easily seen and where everything depends on everything else.

Perhaps we should ask:do not have the capacity to understand the cosmos? Do we have to abandon scientific realism as the means of progressively building a complete theory of everything? Has cosmology become philosophy? What follows are some interesting ideas presented by imminent thinkers in their field about the Limits of Science. The first video is by Richard Dawkins and Lawrence Krauss about the absurdity of quantum physics.

The next video by Dawkins and Weinberg is about how mathematics enabled us to cope with the strangeness of quantum mechanics

Perhaps we should not take refuge in the idea that our biological evolution did not depend on our understanding of quantum physics but our future may depend heavily on using quantum physics. Excerpts from — The Limits of Science - Het Denkgelag.

Finally, we can not leave this debate without words from Sabine Hossenfelder.

Since the first posting on the Big Bang Theory (λCDM) we have encountered many objections and differing views on what scientific realism tells about the cosmos. The next posting is on the excellent commentary presented by philosopher, Bjorn Ekeberg
