Universe from Arc block #1,503
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 | 5.113×10⁻¹² m³kg⁻¹s⁻² | 0.077× ours |
| Gravitational coupling αG | 0.067× 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.
