Universe from Arc block #249
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 | 1/138.36 | 0.990× ours (1/137.04) |
| Speed of light c | 327,336 km/s | 1.092× ours |
| Planck constant h | 7.526×10⁻³⁴ J·s | 1.136× ours |
| Elementary charge e | 1.776×10⁻¹⁹ C | 1.108× ours |
| Gravitational constant G | 4.477×10⁻¹² m³kg⁻¹s⁻² | 0.067× ours |
| Gravitational coupling αG | 0.054× 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.
