← ScienceWhich phenomenon causes increased pond volume measurement error on approach?
A)Gravitational time dilation gradient shift✓
B)Differential expansion altered spacetime
C)Kinetic energy density compresses fluids
D)Osmotic pressure inflates larger algae
💡 Explanation
Increased probe altitude experiences gravitational time dilation; the *Shapiro delay* increases path length because spacetime intervals depend on gravitation potentials, therefore the volume estimate increases, rather than physical pond properties or instrument errors at lower altitudes.
