Cosmology

# Space considers to be a three dimensional extent and that is boundless where objects and events are relative.  # Sir Issac Newton considered space as independent and is permanent whether there was / is any matter into space.  # Space considers to be a three dimensional Cartesian coordinate system and is used to indicate positions in space.  # Natural Philosopher “Gottfried Leibniz” said that space is a collection of relation between objects and is given by their directions and distance from one another.  # In Non-Euclidean Space, space is considered to be a curved rather than flat and even Albert Einstein’s “General Relativity” expressed space around the gravitational field and hence deviates Euclidean space.  # Philosopher Immanuel Kant developed his theory of knowledge in which space is both a priori and synthetic.  # Albert Einstein even considered space and time as a single entity and later know as “Spacetime”. In his theory, speed of light in vacuum is same for all observe
