Universe from Arc block #83
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.

| Fine-structure constant α | 1/137.25 | 0.998× ours (1/137.04) |
| Speed of light c | 304,808 km/s | 1.017× ours |
| Planck constant h | 6.617×10⁻³⁴ J·s | 0.999× ours |
| Elementary charge e | 1.613×10⁻¹⁹ C | 1.007× ours |
| Gravitational constant G | 7.525×10⁻¹¹ m³kg⁻¹s⁻² | 1.128× ours |
| Gravitational coupling αG | 1.109× 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.
