Why is the Schwarzschild radius significant?

Question

Quizplus · Accepted Answer

The Schwarzschild radius is the distance from the center of a black hole at which the gravitational pull is so strong that nothing, not even light, can escape it. This is also known as the event horizon. Therefore, option B is the correct answer. Option A is incorrect because space-time itself does not break down within the Schwarzschild radius, rather it is severely warped by gravity. Option C is incorrect because gravitational lensing can occur at various distances from a massive object, not just at the Schwarzschild radius. Option D is also incorrect because the tidal forces become progressively stronger as you get closer to the black hole, not just at the Schwarzschild radius.
