However, the amount of helium in the universe, as measured by spectroscopy, suggests that there are far more baryons in the universe than estimates based on galactic luminosity indicate.
然而，通过光谱学测量，宇宙中氦的数量表明，宇宙中重子的数量要比基于星系光度所估计的要多得多。

All particles which are together with the neutrons and protons are called baryons.
所有与中子、质子放在一起的粒子统称为重子。

"For us, made of baryons, to exist, the mirror of charge-parity symmetry needs to be broken," Buckley explains.
