Scientists question nature's fundamental laws

Public confidence in the "constants" of nature may be at an all time low.

Recent research has found evidence that the value of certain fundamental parameters, such as the speed of light or the invisible glue that holds nuclei together, may have been different in the past.

"There is absolutely no reason these constants should be constant," says astronomer Michael Murphy of the University of Cambridge. "These are famous numbers in physics, but we have no real reason for why they are what they are."
