That's the point, to get the people who wouldn't otherwise think to eavesdrop on a conversation that involves science.

Perhaps we’ve never been visited by aliens because they have looked upon earth and decided there’s no sign of intelligent life.

You should chose your heroes a-la carte. Picking and choosing from one and then another, thereby assembling a kind of composite hero. That way when you discover something reprehensible about any one of them it matters nothing to you because that's not the part of them that piqued your interest.

Modern science is under no obligation to satisfy the expectations of your five senses.

Without new economies, our old economies get our jobs taken from them because everyone else has figured out how to do it.

My only hope is that every other alien civilization isn't doing exactly what we are doing because then everybody would be listening, nobody would be receiving, and we would collectively conclude that there is no other intelligent life in the universe.

I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.
