So Has Virtual Particles Been Proven To Exist?

[Gold Barz]

Or is it just straight out of the equations? has it been detected?

The Casimir effect:

Is a test for the existence of virtual particles. This effect has been measured.

You can't detect them.That's what they are called virtual.Duhhhh !

However,you needn't go to Casimir effect to prove that Feynman diagrams are a correct symbolical representation of reality,i think a Compton effect is much easier to test/measure.

Also the Lamb Shift.

Well,let's see.1922 vs 1947.
