- Geocentric Model
- Heliocentricity

Indian constitutional amendment procedure is:
- Rigid
- Flexible
- Rigid as well as Flexible
- None
Indian constitution is more flexible than rigid. For example, most of its provisions can be amended by a two-thirds majority in the parliament. However, in order to amend some of the provisions like the election of the president, powers and functions, the extent of Centre-State relations, etc. apart from two-thirds majority in both houses of the parliament, the bill must be passed by at least half of the total state legislatures.
What is the pulsating theory of the universe?
- A cosmological model that combines both the Big Bang and the Big Crunch as part of a cyclical event
- An expansion and contraction of the star as a whole in a regular periodic pulsation
- All the matter of the universe was present in a single place in the form of hot and dense fireball
- Counting of the galaxies is constant and new galaxies which are forming continuously are filling the empty spaces
Sir J.C. Bose proposed a theory of the ascent of sap known as the pulsation theory. The Pulsating Universe Theory says that the universe follows self-sustaining cycles such as expanding and contrasting.
In which year was the constituent assembly established?
The constituent assembly was formed in 1946 on the basis of the cabinet mission plan.
