the cyclic universe, the multiverse, the brane hypotheses have been compared to the static v expanding universe , and the expanding universe ( even with a "newer" Einstein Cosmo constant) has strong evidence to support it. Now, that still doesnt help with the multiverse or brane model.
Science is often a slow detailed pursuit of what becoms unknowable nly after we exhaustively test it.
I am interested in how our knowledge advances about how long planets in our solar system stay tectonically active and how that quickly swept away a "given time realm" idea for "Tectonically alive" planetary bodies. . I am in awe of how longsome of our cosmologists and planetary travel design engineers will spend 25 years on one space shot. They will come to work every day in the wait for the "critical fly by" moment from concept to final data dump cn be an entire professional life for most of these people.
