Format B - Newton Was Wrong

Einstein predicted that stuff that consists of photons (which have zero mass)
would be affected by the curvature of spacetime. This prediction turned out to be
true and is an important tool in the field of astronomy. Newton's formula implies
that only things with mass are affected by gravity, which is incorrect. For more
information on this subject, search for "gravitational lensing". There are some
really cool pictures of this on the web.
