Phobos is the best known irregular satellite in our solar system, but it isn't a squoon. (ESA/DLR/FU Berlin (G Neukum), CC BY-SA 3.0 IGO) Well let’s think about the physics: for a satellite to be ...

There may be a fifth fundamental force of the universe that we haven’t documented yet — and, according to new research, our best bet of uncovering it may not lie in deep space, but in objects ...

A tiny wobbling particle may be about to reveal a fifth force of nature, scientists behind one of the biggest particle physics experiments say. Physicists at the Fermi National Accelerator Laboratory, ...

A math theory powering computer image compression, an "invisibility cloak" or the science behind the James Webb Space ...

The Standard Model of Particle Physics accounts for four fundamental forces—strong, weak, electromagnetism, and gravity—but for decades, scientists have wondered if an elusive fifth force might be at ...

This is a cooler physics problem than I initially realized. It goes something like this. A block has a mass of 1 kg and is placed on a vertical wall such that the coefficient of static friction is 0.5 ...
