Oxford Dictionary defines the adverb even as:
used to emphasize something surprising or extreme.
"they have never even heard of the US"
synonyms: surprisingly, unexpectedly, paradoxically
"even the best hitters missed the ball"
- used in comparisons for emphasis.
"he knows even less about it than I do"
synonyms: still, yet, more, all the more
"it got even colder"
Is there a stronger version of this? My example is:
The LHC machine, even when it found the Higgs boson, _______ when it find the tachyon, is still only a combination of atoms.
Finding out the Higgs boson is already extraodinary, but being able find out the tachyon is unimaginable.
