Theories and Controversies Surrounding Universe

3

Astronomers since ages and astrophysicists, solar scientists, and space researchers of late have propounded cosmic theories that have made the universe (as we know it) more mysterious and elusive. Most astronomers aver that the universe which was created about 13.2 billion years ago via a ‘Big Bang’ explosion continues to burgeon perpetually. However, an astrophysicist team from Lawrenceville Plasma Physics Inc have propounded that the universe may not simply be expanding.

According to these space researchers, unlike the postulations of the Big Bang theory, the space around our immediate universe comprising the Milky Way, the solar family, and the space above our earth, objects apparently tend to diminish and look dimmer as they move away. Surprisingly enough, the predictions of this hypothesis hold good as do those from the Big Bang that entails complicated rectifications concerning alleged dark energy and dark matter.

Rig-Veda, most ancient of the Hindu Vedas which was penned between 15th and 12th century BCE details an oscillating universe that came out of an egg, cosmic egg to be precise. It was in this egg that the entire universe made up of the sun, moon, stars, planets, and the infinite space was contained. All these cosmic bodies during an oscillating moment emerged out of the egg and then in the next cyclical phase collapsed or contracted back into the egg.

The geocentric theory-where the earth lies at the universe’s center-was first proposed by Aristotle, a Greek scientist and philosopher in the 4th century B.C. All other celestial bodies including the planets, stars, and the sun orbited around the earth. However, he rightly established that there were five chief elements, namely earth, fire, water, air and ether.

Nevertheless, the first individual to put forward a model placing the sun at the universe’s centre with our lonely planet orbiting around it was also a Greek by the name of Aristarchus. Aristarchus was the first mathematician and astronomer to present the heliocentric theory.
