In his book,
The Beginning of Infinity, Oxford physicist David Deutsch writes:
If a one kilometer asteroid had approached the Earth on a collision course at any time in human history before the early twenty-first century, it would have killed at least a substantial proportion of all humans. In that respect, as in many others, we live in an era of unprecedented safety: the twenty-first century is the first ever moment when we have known how to defend ourselves from such impacts, which occur once every 250,000 years or so.
Documentary filmmaker Errol Morris wants to know what you think of Deutsch’s claim, and has set out a brief survey on his blog at the New York Times. Morris told me, "It may seem like another innocuous Internet quiz, but take my word for it—it isn't one." He also said, "There is a hidden question, which I’m not at liberty to reveal, that I think will interest you." and on his blog, he writes "When the results are announced, there will be a surprise."
I'm intrigued! I love surprises, even when they involve killer asteroids.

Chinese researchers demonstrated quantum entanglement at a record distance, between a satellite and ground stations 1,200 kilometers apart. When objects are quantum entangled, their quantum states are linked. Measuring the state of one affects the state of the other. It’s weird shit. So weird that Einstein called it “spooky action at a distance.” The experiment […]
On June 16, 1963, Soviet cosmonaut Valentina Tereshkova became the first woman in space. She orbited the Earth 48 times over a period of three days. Inspired by Yuri Gagarin who in 1961 became the first person in space, Tereshkova applied to the Russian space program and was accepted based on her extensive background as […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
