SUMMARY
The discussion centers on calculating the speed at which Superman must fly away for his blue light (480nm) to appear orange (600nm) using the Doppler Effect. The initial attempt used the formula f' = f / (1 + v_s / v) but yielded an incorrect speed of 75×10^8 m/s, while the correct range is between 57.0×10^6 m/s and 67×10^6 m/s. A participant suggested using the relativistic Doppler effect equation λ = λ₀√((1 - β) / (1 + β)), which is necessary for accurate results in this scenario due to the high speeds involved.
