Question

In the context of modem scientific research, consider the following statements about ‘IceCube', a particle detector located at South Pole, which was recently in the news:

1. It is the world's largest neutrino detector, encompassing a cubic kilometre of ice.
2. It is a powerful telescope to search for dark matter.
3. It is buried deep in the ice.

Which of the statements given above is/are correct?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

Answer:

D

Explanation:

Statement 1 is correct: IceCube is the world's largest neutrino detector, encompassing a cubic kilometer of ice. It consists of an array of sensors embedded deep within the ice at the South Pole.

Statement 2 is partially correct: While IceCube is primarily designed to detect neutrinos, it can also indirectly contribute to the search for dark matter. Neutrinos produced in astrophysical processes involving dark matter interactions could potentially be detected by IceCube.

Statement 3 is correct: IceCube is indeed buried deep in the ice at the South Pole to capture the interactions of neutrinos with the ice. The sensors are distributed over a large volume of ice to maximize the chances of detecting neutrino interactions.
