A Map Of Mars

After a painstaking six years of work, researchers at the Jet Propulsion Laboratory at Caltech have put together tens of thousands of images from Mars in one map. With just a few clicks you can now explore craters on Mars all on your own. Map here, press release here. 

New Cosmology Anomaly Confirmed, Particle Physics Anomaly Vanishes

You can check out the newest Science News episode here.Today we talk about water on the moon, space skin, quantum light, how crystals grow, mind-controlled robots, blood as fuel, nano-ink, a new projection for population growth, and of course, the telephone will ring. 

Double-Slit Experiment in Time

This week’s quantum news held a new version of the double-slit. Rather than the usual two slits at a spatial separation, the experimentalists used two slits separated in time. This is a weird way of saying they allowed a laser beam to either go, or not go, through a plate at two time-intervals. Rather than producing an interference pattern on a screen, this setup produces an interference in the time-domain which effectively spreads out the frequencies of the beam. It makes more sense in maths, I swear. Paper here. Summary here.

The Underwater Professor

Joseph Dituri, associate professor at the University of South Florida, is conducting a self-experiment to explore the effect of sustained, increased atmospheric pressure on the human body. The 55-year old has lived in a small habitat 10 meters below the ocean surface since March 1 and plans on staying there for 100 days. Video here. More details here.

In this week’s video, I review the common arguments for why faster-than-light travel is impossible and explain why I find them inconclusive.
