Considering that less than 20 years ago there were no known extrasolar planets, no one had ever even thought up of the Holographic universe theory, or debated the existence (and implications) of a firewall around blackholes, not to mention the so dark we still can't find it Dark Matter... I mean - we haven't even made enough discoveries to start making theories yet with Exoplanets (gaseous Super Earths are brand new in the past year, I believe), and cosmology has huge areas to explore and craft experiments around that are literally brand new.
I think we're going to be just fine in the theory and spectacular discovery department.
Wow, with that kind of forward thinking you could run for Congress, or be a pundit!
Hey - I have some land on Mount St Helens that I'd like to sell - want some?
If you fail to plan, plan to fail.
