Title: Is there an opposite of light?
Post by: thedoc on 05/02/2016 22:50:02

Grant Skinner asked the Naked Scientists:
   it seems that there is an opposite for most things - matter, anti-matter and so on.  Is there such a thing as the opposite of light such as an anti-light or dark-light (rather than just dark)
What do you think?

mass reflects light, and since a true vacuum is impossible even opposites are part of the same spectrum- in this case mass is the opposite of light on the energy spectrum.
