dark matter killed the dinosaurs?

A new book proposes that dark matter changed the course of a comet, which killed the dinosaurs. This article is also interesting to me for its possibly over the top use of analogies to communicate scientific information.

Sixty-­six million years ago, according to her dark-matter disk model, a tiny twitch caused by an invisible force in the far reaches of the cosmos hurled a comet three times the width of Manhattan toward Earth at least 700 times the speed of a car on a freeway. The collision produced the most powerful earthquake of all time and released energy a billion times that of an atomic bomb, heating the atmosphere into an incandescent furnace that killed three-quarters of Earthlings. No creature heavier than 55 pounds, or about the size of a Dalmatian, survived. The death of the dinosaurs made possible the subsequent rise of mammalian dominance, without which you and I would not have evolved to ponder the perplexities of the cosmos.

environmentalists and poor communication

Here a marketing person criticizes the communication strategies of scientists and environmentalists.

our side likes complexity. And in communications, only simplicity works. Our side doesn’t like simplicity because they view it as manipulative or not capturing the truth. Without simplicity, people don’t remember anything. Another thing: The research shows and common sense tells you that that this is a really tough, depressing issue to get your head around. So they really can’t do it unless they know what can be done about it. And we don’t put forward a clear solution. Go out on the street and ask people, “What can we do about climate change?” They won’t know. So we have to make this a lot simpler…

Public interest types, across the board — we think because we’ve said something, know something, or done something, that everybody else knows it. We don’t realize the bubble we live in.  It’s only when you’ve said something so many times that you’re utterly and completely sick of it that someone has even heard it. Marketers understand this. Scientists and people from the humanities less so — they get bored by it. “We already had our op-ed in the New York Times! The world knows!” But it takes so much more repetition than that.

I mean, as a country, even the intelligentsia has not fully realized that we are in a planetary emergency and we are running rapidly out of time.

Actually, I get criticized by my fellow engineers almost daily for oversimplifying complex issues and for repeating myself to the point of annoyance. It turns out, maybe I have some communication instincts after all!
