Which telescope was used to determine that, dark matter is not made up of tiny primordial black holes as stated by Stephen Hawking?
Options
A. Hobby-Eberly Telescope
B. Subaru telescope
C. Large Binocular Telescope
D. Large Zenith Telescope
Correct Answer
Subaru telescope
Explanation
An international research team including Dr. Surhud More and Dr. Anupreeta More from Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune has ruled out the possibility of primordial black holes being a major constituent of dark matter using Subaru telescope. This finding disproves a theoretical claim of Prof Stephen Hawking. In the solar system, Mercury, the planet closest to the Sun, takes just 88 days to make one revolution around the sun, while Neptune, the farthest one, takes 165 years to make one round. In like manner, laws of gravity expect us to see stars closer to the centre of galaxies rotating faster than the stars on the edge.
