← ScienceWhich risk increases as an astronaut approaches a black hole's event horizon?
A)Tidal forces cause spaghettification✓
B)Atmospheric drag greatly increases
C)Neutrino flux damages spacecraft
D)Solar radiation rapidly degrades sensors
💡 Explanation
Spaghettification risk increases because extreme gravity gradients induce differential gravitational forces which stretch objects. Because of spacetime curvature, near the event horizon, the tidal forces dominate, therefore stretching increases exponentially rather than alternative external effects.
