Scientists Solve Century-Old Optics Mystery

evan_arrrr! writes "From the article: Since the early 20th century physicists have known that light carries momentum, but the way this momentum changes as light passes through different media is much less clear. Two rival theories of the time predicted precisely the opposite effect for light incident on a dielectric: one suggesting it pushes the surface in the direction light is traveling; the other suggesting it drags the surface backwards towards the source of light. After 100 years of conflicting experimental results, a team of experimentalists from China believe they have finally found a resolution."

Light has infinite mass not zero mass.

Both zero and infinite mass work in all of the equations.



Scientists have been contradicting themselves for decades. They all know light has mass. They also know that to travel at the speed of light requires infinite mass.


Since no one can figure out how infinite mass and a light particle would work (and it does), scientist just pretend light has zero mass... It's so much simpler than acknowledging that mass radically changes at the speed of light and that infinite mass is zero mass.
