We could perhaps in 2,000 years solve the problem, unless the science deniers continue to win. I mean, can’t you see the global warming deniers approaching this comet the same way? They would be arguing “there is not consensus” it is a threat, finding the one scientist in 50 that agrees with them to claim his view should be given equal weight. I can just hear demagogic politicians on the year 4500 version of Twitter screaming that it is all “fake news.”
