Are Therevada's cosmology and the Mahanaya's sutras physically impossible? Are Therevada's cosmology and the Mahanaya's sutras physically, rather than only psychologically, plasusible?

I read about the former in the abhidharmakosabhasyam, about all the hells and heavens that await us. And the Mahayana sutras often include reference to e.g. celestial bodhisattvas.

I'm skeptical that these things have physical, rather than psychological, truth, empirical (we've this heaven) or otherwise (we have evidence that these heavens exist). As with with classical georgraphy, and history. My specific question is:


do we have good reason to believe that physics will end up allowing a Buddhist timeline of events?
Buddhism is a definite, and it is the same Dhamma preached by all Buddhas. Popular science is always changing with new theory replacing old ones. But having said this some similar theories have emerged:


Parallel universe - Multiverse
Multiple worlds - Planetary habitability
Cyclical universe - Cyclic model, One Big Bang, or were there many?, Multiple Big Bang theory could bring 'Copernican revolution' says Astronomer Royal
