A couple of items from the world of physics today. I’m not sure what you can do with this information, but it seems like fun.
1. Sound apparently has mass and weight
New experiments with sound waves point to the possibilities that sound waves possess mass. That would mean
Even weirder is that phonons have negative gravity, meaning that they fall “up.”
Are there any practical applications for this potential discovery? Not yet, but you never know.
2. This strange shape cancels out almost all sound
There are moments when we crave quiet, which explains the popularity of noise-canceling headphones. Researchers at Boson University may have found something better.
They’ve been working with something
