No, German Scientists Have Not Confirmed the “Impossible” EMDrive

Two German researchers claim they have produced measurable amounts of thrust using a copy of NASA’s controversial EMDrive. It’s a result that has many people talking, but don’t plan your trip to the to the Alpha Centauri system just yet—the experts we spoke with are all highly skeptical of the study and its findings. »7/28/15 1:40pm

Our Physicist Explains The Deal With Mass And Weight Once And For All

If people in glass houses shouldn’t throw rocks, then I’m a pitching machine crammed with gravel and I live in Philip Johnson’s summer house. You see, I’m a brutal little bitch when I find stupid mistakes in articles about cars, and then just the other day I made one of the most basic physics mistakes you can make. I… »7/16/15 12:20pm

New Test Suggests NASA's "Impossible" EM Drive Will Work In Space

Last year, NASA’s advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive, or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum. »4/30/15 10:15am

A Glimpse Inside The Secretive World Of Human Cannonballs

Once she has lowered herself into the mouth of the cannon and slid down to the base of the barrel, Gemma “The Jet” Kirby performs a series of breath-synchronized movements that seem more suited to yoga or lamaze than to one of the deadliest stunts in circus history. This sequence is the culmination of hours of… »4/30/15 2:32pm

Why the Human Body Can't Handle Heavy Acceleration

Our bodies are surprisingly resilient in many situations, but rapid acceleration is not one of them. While the human body can withstand any constant speed—be it 20 miles per hour or 20 billion miles per hour—we can only change that rate of travel relatively slowly. Speed up or slow down too quickly and it's lights… »10/01/14 2:20pm

Traffic Jam Torment: Physics Proves That Bottlenecks Are Bulls**t

Traffic jams stand no chance under the onslaught of giant throbbing Japanese physicist brains! Well, to be accurate, physicists from the Land of the Rising Sun haven't exactly cracked the traffic-jam conundrum. But they have figured out why it took me four mother!@#$ing hours to crawl up the mother!@#$ing I-5 from San… »3/04/08 3:45pm
