Topic: Awareness in the fields of Space Q6. What is Hawking radiation, and why is detecting it considered a crucial step toward unifying quantum physics and gravity? (10 M) Difficulty Level: Difficult Reference: TH Why the question: Renewed global focus on detecting Hawking radiation through high-energy observations like the 2025 CNRS “black hole morsel” study, …
Source: NDTV Context: Scientists have detected GW231123, the largest black hole merger ever recorded, using the LIGO-Virgo-KAGRA (LVK) network, revealing black holes 100x and 140x the Sun’s mass—a discovery that challenges existing theories of stellar evolution. About Black Hole Merger GW231123: What Is a Black Hole Merger? A black hole merger is a cosmic event …
Facts for Prelims (FFP) Source: PIB How are scientists trying to unify the two theories? Scientists are researching how atoms falling into a black hole emit radiation and its quantum behaviour, resembling Hawking radiation. Their calculations on this radiation, known as “horizon brightened acceleration radiation entropy,” reveal insights into the Einstein principle …
