Researchers have just found evidence of “dark electrons”—electrons you can’t see using spectroscopy—in solid materials.
By analyzing the electrons in palladium diselenide, the team was able to find states that functionally cancel each other out, blocking the electrons in those “dark states” from view.
The scientists believe this behavior is likely to be found across many other substances as well, and could help explain why some superconductors behave in unexpected ways.

destructive interference, and you get a darker signal. If the waves are perfectly ‘opposite,’ the destructive interference is at its most extreme, and you get no signal at all.

Btw, what happens with the energy in destructive interference? Heat?
