Universe from Arc block #1,721
Observers possible可能诞生观察者
Grade S · observers possible
Galaxies, stars, planets and chemistry all exist, and stars live long enough for complex processes to unfold. Under this model the conditions for observers are met. Only a few percent of blocks get this far.

| Gravitational constant G | 7.686×10⁻¹¹ m³kg⁻¹s⁻² | 1.152× ours |
| Gravitational coupling αG | 1.168× ours |
Constants are reported in an external frame. Only α and αG are observable from inside the universe; c, h, e and G can be rescaled without changing what its inhabitants could measure.
