comment Analyzing electron-positron scattering cross section in detail
There is nothing being subtracted; there is only the amplitudes having opposite signs. (Destructive) interference is a very basic property even of classical wave mechanics: en.wikipedia.org/wiki/Interference_(wave_propagation)

comment Analyzing electron-positron scattering cross section in detail
seeking_infinity, please think twice before "correcting" s-channel and t-channel in the question again. The original question had it all upside-down.

revised Is Gravity Energy?
Yes, it may seem minor, but (as suggested in the comments) there is a substancial difference between using a noun or a verb, the latter making more sense for an interaction.

comment Is Gravity Energy?
If I get your point right, @JoeH, you're saying that gravitation (a verb) is more suited to the correct interpretation as an interaction, whereas gravity (a noun) tends to be picked up as a thing?
