Citando:
"So what does the most precise measurement of antimatter even tell us? Well, unfortunately, not much more than we already knew. As expected, hydrogen and antihydrogen — matter and antimatter — behave identically. Now, we just know that they're identical at a measurement of parts per trillion. However, Ulmer said the 2-parts-per-trillion measurement does not rule out the possibility that something is deviating between the two types of matter at an even greater level of precision that has thus far defied measurement.
As for Hangst, he's less concerned with answering the question of why our universe of matter exists as it does without antimatter — what he calls "the elephant in the room." Instead, he and his group want to focus on making even more precise measurements, and exploring how antimatter reacts with gravity — does it fall down like normal matter, or could it fall up?"
