Why X-rays and Gamma-rays are different in nature, though both are of eletromagnetic origin?
Asked by: Buddhadev
Gamma rays refer to electromagnetic radiation from nuclear interactions while X-rays
come from atomic interactions. But they are both high energy electromagnetic radiation
and, if you didn't already know the source, you couldn't tell for sure if a particular
photon was a gamma-ray or an X-ray. Gammas tend to be higher in energy since nuclear
binding potentials are larger than atomic potentials but there is overlap in the two

'The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative... '
