Question

The initial concept about the origin of universe was given by:

1. Bondi
2. Hawllacks
3. Narlikar
4. Hubble

Answer 1

In the year 1920 Edwin Hubble observed that galaxies are spreading away from us in all directions.
Years later the Big Bang concept was easy to understand.
Let’s get into the further history of the universe to confirm the person who gave the initial concept of the universe.

Complete step by step solution:
Let us define the Universe first and then we will discuss some history to know the person behind the concept of the Universe.

Universe is defined as all of space and time and their contents; contents comprise all of energy in its various forms, including electromagnetic radiation and matter and therefore planets, moons, stars, galaxies and the contents of intergalactic space.

A priest named Georges Lemaitre first suggested the Big Bang theory in the 1920s, in which he theorised that the Universe begins from a single primordial atom.

The research further speeded up when Edwin Hubble’s observations showed that galaxies are moving far away from us in all directions. Along with Hubble, Arno Penzias and Robert Wilson contributed the discovery of cosmic microwave radiation.

Thus, as per the given options Hubble gave the initial concept of universe.

Option 4 is correct.

Note: The Hubble space telescope, one of the largest and most versatile research tools. The Hubble Telescope is named after astronomer Edwin Hubble. Hubble is the only Telescope designed to be maintained in space by astronomers. Five space shuttle missions have repaired, upgraded and replaced systems on the Telescope. Hubble was successfully launched by Space Shuttle Discovery in 1990 with the drawback of spherical aberration which was corrected in the year 1993.
