In our world, the standard model of particle physics contains within it the fairly intractable theory called QCD. A toy version with two colours is often studied as a model confining and chiral symmetry breaking field theory. Here, we investigate the cascade of changes at various distance scales if we make this change within the standard model. It is possible to limit the changes at the hadronic scale. However, the minor changes that occur actually cascade down to the far infrared, into nuclear and atomic physics, and chemistry. Through this, it also possibly affects the evolution of stars and galaxies. We remark on this unexpected sensitivity of the universe to physics at the scale of quarks.

在我们的世界中，粒子物理学的标准模型中包含相当棘手的理论，称为 QCD。具有两种颜色的玩具版本通常被研究为模型限制和手征对称破坏场理论。在这里，如果我们在标准模型中进行这种更改，我们将研究不同距离尺度上的级联变化。可以限制强子尺度的变化。然而，发生的微小变化实际上会级联到远红外线、核物理和原子物理以及化学。通过这个，它也可能影响恒星和星系的演化。我们评论了宇宙对夸克尺度物理的这种出乎意料的敏感性。
