Today's XKCD What If? explores many of the benefits that would accrue to the human race if the Sun were suddenly extinguished.
Reduced risk of solar flares: In 1859, a massive solar flare and geomagnetic storm hit the Earth. Magnetic storms induce electric currents in wires. Unfortunately for us, by 1859 we had wrapped the Earth in telegraph wires. The storm caused powerful currents in those wires, knocking out communications and in some cases causing telegraph equipment to catch fire.
Since 1859, we've wrapped the Earth in a lot more wires. If the 1859 storm hit us today, the Department of Homeland Security estimates the economic damage to the US alone would be several trillion dollars—more than every hurricane which has ever hit the US combined. If the Sun went out, this threat would be eliminated.
Improved satellite service: When a communications satellite passes in front of the Sun, the Sun can drown out the satellite's radio signal, causing an interruption in service. Deactivating the Sun would solve this problem.
Better astronomy: Without the Sun, ground-based observatories would be able to operate around the clock. The cooler air would create less atmospheric noise, which would reduce the load on adaptive optics systems and allow for sharper images.
Stable dust: Without sunlight, there would be no Poynting–Robertson drag, which means we would finally be able to place dust into a stable orbit around the Sun without the orbits decaying. I’m not sure whether anyone wants to do that, but you never know.
Reduced infrastructure costs: The Department of Transportation estimates that it would cost $20 billion per year over the next 20 years to repair and maintain all US bridges. Most US bridges are over water; without the Sun, we could save money by simply driving on a strip of asphalt laid across the ice.
Princeton University psych prof Susan Fiske published an open letter denouncing the practice of using social media to call out statistical errors in psychology research, describing the people who do this as “terrorists” and arguing that this was toxic because of the structure of social science scholarship, having an outsized effect on careers.
Blue writes, “Peter Watts has be stricken with debilitating pain, loss of range of motion and motor control. Watts’ doctors remain baffled despite a battery of tests, and Watts has reached out to his fans to ask for their theories and ideas as to what might be causing his illness.”
Today, I’ve launched a very special Kickstarter with two friends, Timothy Daly and Lawrence Azerrad. A year in the making (and many more years on our minds), the Voyager Golden Record: 40th Anniversary Edition is the first vinyl release of the stunning golden phonograph record launched by NASA in 1977 aboard the Voyager spacecraft, one […]
If you own a dog, you’ve most likely heard of BarkBox – the monthly subscription box for dogs. What started as a simple idea to try out the subscription model on pet owners has since developed a cult following of dog lovers. If you haven’t given it a try yet, this one month free deal is the […]
With the iPhone headphone jack having gone by the wayside, we’re excited about the addition of the FRANKLIN Bluetooth Headphones in our store. These headphones are foldable so they’re easy to carry around, but most importantly, they pack impressive sound. Our biggest struggle with Bluetooth headphones is the worry of them dying at the worst moment. This pair lasts an impressive 8-10 […]
