“some Christians are upset because it seems to be a dig or a blasphemy against God”
Then why call it god particle? Do you think it is?
No one thinks it’s a god. Everyone who understands it knows it’s of utmost importance, because it ties everything together - so important that it got nicknamed with the most reverent name with which one can nick. Had we somehow not been able to discover the neutron until now, it would have been extremely-mega-super important to tying everything up, and then it would be the god particle, and would receive the same amount of non-worship.
