The anthropic principle posits that the universe’s physical constants are fine-tuned for life, which is a problem for big bang cosmology. On the Genesis Science Network we discuss the theoretical proposal of a test of the anthropic principle via a proposed ultralight axionic dark-matter particle.

I presented on the subject of problems for the big bang on the YouTube channel Standing for Truth Ministries. I discussed the most common problems the big bang theory has, the contradictions, fudge factors and failures.

Big bang cosmology faces unresolved problems with the standard ΛCDM model needing unknown fudge factors. A new timescape cosmology, where time passes faster or slower in voids and filaments of the cosmic web, may resolve the Dark Energy problem, but it indicates a need to rethink the foundations of cosmology.
