to see if there is a slight imbalance if anti hydrogen does not in fact behave the same as normal hydrogen. maybe gravity affects it ever so slightly differently. this is the top of the alpha g machine, where g stands for gravity. this is the device that we are using to try and answer the question, what happens to antimatter if you drop it in the gravitational field of the earth. if your experiment found that anti hydrogen falls up instead of down under gravity, what happens next? that would be super cool. that would be a complete revolution in science. that s a completely unanticipated result and would mean new physics, and probably a nobel prize for somebody who happens to be involved. i don t want to say me, because i helped bring
