With reference to the black hole, consider the following statements:1....
Statement 1: A black hole is a place in space where gravitational force is so high that even light cannot get out.
This statement is correct. A black hole is a region in space where the gravitational force is extremely strong due to the presence of a massive object. The gravitational force is so intense that it causes a distortion of spacetime, creating a region from which nothing, including light, can escape. This boundary is known as the event horizon. Anything that crosses the event horizon is pulled towards the center of the black hole, known as the singularity, where the mass is concentrated. The gravitational force in a black hole is so strong that it overcomes all other forces, including electromagnetic forces that allow light to travel.
Statement 2: High configuration space telescopes cannot find black holes.
This statement is incorrect. High configuration space telescopes, such as the Hubble Space Telescope, have played a crucial role in the detection and study of black holes. While black holes themselves are not directly visible, their presence can be inferred through their effects on nearby objects or by observing the behavior of matter falling into them. Astronomers use various techniques to identify and study black holes, including detecting the X-ray emissions from hot gas falling into a black hole, observing the gravitational effects on nearby stars, or studying the motion of gas and stars in the vicinity of a black hole. These observations can be made using high configuration space telescopes equipped with specialized instruments sensitive to different wavelengths of light.
Therefore, the correct answer is option 'A' - 1 only. Statement 1 is correct, while statement 2 is incorrect.

With reference to the black hole, consider the following statements:1....
Scientists from the Event Horizon Telescope (EHT) facility, a collaboration of over 300 researchers, revealed the first image of the black hole at the centre of the Milky Way in press conferences held around the world.
- This image of the black hole referred to as Sagittarius A* (SgrA*) gave further support to the idea that the compact object at the centre of our galaxy is indeed a black hole.
- A black hole is a place in space where gravitational force is so high that even light cannot get out.
- The gravity is so strong because the matter has been squeezed into a tiny space. This can happen when a star is dying.
- Because no light can get out, one can't see black holes. They are invisible.
- High configuration space telescopes can help find black holes.
- Black holes in the modern sense were first predicted as a consequence of Albert Einstein’s general Theory of relativity in 1915.
Hence only statement 1 is correct.
