Which mechanism fundamentally limits fiber optic communication across astronomical distances?

💡 Explanation

Gravitational lensing bends light due to spacetime curvature near massive objects, causing dispersion because varied paths yield inconsistent arrival times across vast distances; therefore arrival times broaden rather than through thermal or radio interference.
