Below the Earth’s surface nearly half-a-kilometre down, Indian physicists have established their own laboratory. Dark matter is responsible for holding the galaxies together. The quest for answers relating to dark matter is the main aim of the laboratory. This is India’s first venture in this field of science.
Presence of parallel universe or multiple universes is no longer limited to science fiction. Physicists have deduced the idea of ‘multiverse’ made possible through various laws of physics.
Dark matter is a hypothetical type of matter distinct from baryonic matter (ordinary matter such as protons and neutrons), neutrinos and dark energy.
A Grand Unified Theory (GUT) is a model in particle physics in which at high energy, the three gauge interactions of the Standard Model which define the electromagnetic, weak, and strong interactions or forces, are merged into one single force.
In astronomy, the geocentric model (also known as geocentrism, or the Ptolemaic system) is a superseded description of the universe with Earth at the centre. Under the geocentric model, the Sun, Moon, stars, and planets all circled Earth.
Stars. Universe has confounded mankind since ancient times. Early man would look up at the night sky and try to decipher the various shapes and figures created by groups of stars clustered together.
Light and sound are natural phenomena that have fascinated scientists since ancient times. Their varying speeds too have been subject to painstaking hours of experimentation, exploration and enquiry, before scientists were able to obtain concrete information about it.
Humans have been exploring the universe for quite sometime and advancement in technology has helped in its development. This article contains some staggering facts about the universe that we don’t know.
