Fusion · Lawson Criterion
nτT > 3×10²¹ m⁻³·s·keV
Q = P_fusion / P_heating
⟨σv⟩_DT peak ≈ 3.7×10⁻²² m³/s at 70 keV
T_ignition ≈ 13–20 keV (150–230 MK)
ITER: n=10²⁰, τ=3.7s, T=15keV → Q≈10 target
Dyson Sphere · Power Capture
F = L☉ / (4πR²)
P = F × A × coverage × (1−albedo)
T_eq = [F(1−a) / (2σε)]^(1/4)
K = (log₁₀P − 6) / 10
σ_crit = L/(4πGMc) for radiation-pressure hover
Black Hole · Kerr Metric
rₛ = 2GM/c²
r± = (rₛ/2)(1 ± √(1−a²))
T_H = ℏc³ / (8πGMk_B)
η_max(Penrose) ≈ 29.3% (a→1)
BZ: P ∝ a²B²M² — requires accreting magnetized plasma
