Einstein’s Predictions for Gravity Have Been Tested at the Largest Possible Scale

According to the Standard Model of Particle Physics, the Universe is governed by four fundamental forces: electromagnetism, the weak nuclear force, the strong nuclear force, and gravity. Whereas the first three are described by Quantum Mechanics, gravity is described by Einstein’s Theory of General Relativity. Surprisingly, gravity is the one that presents the biggest challenges … Read more

Researchers quantify the amount of energy that plants use to lift water on a global scale

Hurricane category isn’t the full picture. Scientists suggest it’s time for a new scale

Credit: CC0 Public Domain Nothing drives hurricane experts crazier than the sentiment, “Oh, it’s just a Category 1.” It’s not just an annoying attitude, it’s a deadly one. Hardly a hurricane season goes by without a fresh example of a low-category storm causing more trouble than people expected. Last year, Hurricane Ida swept from Louisiana … Read more
