# Sir Issac Newton considered space as independent and is permanent whether there was / is any matter into 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 observers.

# Carl Friedrich Gauss was the first to investigate geometrical structure of space and even Henri Poincare a physicist also have a futility to attempt to discovers which geometry applies to space by experiment.

# But what exactly space is, not a question but why it is, is a question that synthesis all entire forces?
