::::::: Photons are not at rest. Photons do have inertia. You say that the Newtonian mechanics prediction is not correct, but it is a historical fact that Newtonian mechanics did make that prediction. [[User:RSchlafly|RSchlafly]] 11:20, 19 November 2009 (EST)

:::::::: You are absolutely correct that "Newtonian mechanics did make that prediction." It did, in the past tense, 200 years ago when light was thought to be corpuscular.
:::::::: But the article doesn't say that it ''did,'' once, predict this; it falsely says that it ''does,'' in the present tense, predict the deflection of light. Note that this is not a change in Newtonian mechanics itself, but the assumption of what light is.
:::::::: Likewise, scientists ''did'' think that light passed through an ether; it would be false to say that they think this now.--[[User:NgSmith|NgSmith]]
