Lawrence Krauss on Caveman Common Sense
The physicist argues that our common sense is based on evolutionary imperatives that have less to do with the universe as it is than with what our ancestors ...

We evolved as human beings a few million years ago on the Savanna in Africa and we evolved to escape tigers, or lions, or predators. And so what makes common sense to us is the world on our scale. You know, how to throw a rock or a spear or how to find a cave and we didn’t evolve to understand quantum mechanics. And, therefore, it’s not too surprising that on scales vastly different than the kind of experience we had as we were evolving as a species, that nature seems strange and sometimes almost unfathomable, certainly violates our common sense. Our sense of what is common sense and what's intuition. But as I like to say, the universe doesn't care about our common sense. We have to force our ideas to conform to the evidence of reality rather than the other way around And if rea...
