Layman here just getting into how fucked cosmology and astrophysics are currently.
Cosmic inflation theory had three major issues 30 years ago when it started and those problems have never been worse, though some argue that they were never problems in the first place; a case of asking the wrong questions for the right reasons as its produced 30 years of mathematical models that we still shouldn't throw out just yet.
There is a small and growing group of scientists shouting at everyone else PROVE it, basically that inflation and the many worlds interpretation is unfalsifiable and not scientific and the last 30 years have been mostly ad hoc theories.
Then we don't seen to have any idea how old the universe is because the rate of expansion seems to be what ever is covenant for your model because we don't have a mechanism for expansion. Oh and it changes sometimes or can or will... again with no mechanisms.
To top it off we are getting really close to confirming that we'll never be able to test or detect dark matter.
