>>12673189it took 50 years for the Higgs boson to be discovered, and 100 years for gravitational waves to be discovered. actually Laplace iirc predicted black holes so that was like 300 years till we got the photo.
and honestly, laplace and einstein could never have predicted whether or when the experimental technology would be available. for all they knew it was completely undetectable forever.
lesson is if you can make a physical prediction then you should do it and wait for miracles in technology to catch up, since they do happen
