… by wiping out the dinosaurs
Just as, we are told, climate change jump started evoltion and fast food is derailing it, we learn from a “leading Harvard physicist” a radical new theory, courtesy Yahoo News:
Lisa Randall, a theoretical physicist at Harvard University, has a different, and novel answer, which she describes in her latest book, “Dark Matter and the Dinosaurs.”
…
In her latest book, she posits that the extinction of the dinosaurs — necessary for the emergence of humans — is linked to dark matter. Dark matter is the mysterious, invisible matter that astronomers estimate makes up 85% of all matter in our universe.
…
In her book, Randall describes a dark, pancake-shaped patty of densely packed dark matter within our galaxy that could be responsible for our emergence as a species.
Actually, we still haven’t identified any dark matter, and it isn’t self-evident that dinosaurs had to go extinct in order for humans to emerge as a species. (Perhaps a good case can be made, but it is not self-evident.)
While it’s impossible to wind back the clock, proving the existence of the dark disc would greatly advance Randall’s theory. More.
Can we picture this as a summer sci-fi blockbuster though?
Meanwhile, as a friend put it, “What was that Jimmy Durante said? “Everybody wants ta get inta the act!”
