Question 90
Recently, scientists observed the merger of giant 'blackholes' billions of light-years away from the Earth. What is the significance of this observation?
View correct answer and explanation
Correct answer: B
Correct Option: B
Explanation:
Merging black holes cause spacetime ripples detectable as gravitational waves; observations by the LIGO–Virgo network provided striking confirmation of Einstein’s general relativity.
Option-wise Analysis:
A (Incorrect): Higgs boson discovery is related to particle accelerators, not black-hole merger signals.
B (Correct): Black-hole mergers generate detectable gravitational waves.
C (Incorrect): Detection did not demonstrate traversable intergalactic wormholes.
D (Incorrect): It did not directly resolve the physics of singularities inside black holes.
