| "main_sequence_approximation": ( |
| "These values use simple main-sequence scaling laws, so real stars can differ noticeably." |
| ), |
| "extrapolated_mass_range": ( |
| "This mass is outside the range where the scaling laws are calibrated, so the numbers are rough extrapolations." |
| ), |
| "hubble_law_approx": ( |
| "At this redshift the simple linear Hubble law is only an approximation; the distance comes from the full expansion history." |
| ), |
| "relativistic_regime": ( |
| "Speeds or gravity here are strong enough that relativity matters, so Newtonian intuition breaks down." |
| ), |
| "high_eccentricity": ( |
| "This orbit is very stretched, so the distance and speed change dramatically over each orbit." |
| ), |
| "newtonian_approximation": ( |
| "This uses Newtonian gravity, which is an excellent approximation here but ignores relativistic corrections." |
| ), |
| "geostationary": ( |
| "This is a geostationary orbit: the satellite turns with Earth, so it hovers over one spot on the equator." |
| ), |
| "atmospheric_drag": ( |
| "At this height Earth's thin upper atmosphere causes drag that slowly lowers the orbit, so it needs occasional boosts." |
| ), |
| "circular_orbit_approx": "This assumes a circular orbit around a perfectly round body.", |
| "falchi_2015_baseline": ( |
| "Sky darkness comes from the world atlas of light pollution, built from satellite data taken several years ago, so newer lighting is not included." |
| ), |
| "viirs_blind_to_blue": ( |
| "The VIIRS satellite misses much of the blue light from white LEDs, so real growth in light pollution may be larger." |
| ), |
| "moon_and_weather": ( |
| "Moonlight and cloud matter as much as location; plan for a moonless, clear night." |
| ), |
| "low_radiance_noise": ( |
| "The night-light level here is very low, so the percentage change is noisy and should not be over-interpreted." |
| ), |
