Thus, Einstein in his special theory of relativity has given the idea that the speed of light is independent of the motion of all the observers, and space and time are connected in a single continuum.

What this theory says is that if the speed of light remains constant for all the observers then Space and Time have to be changed accordingly. Albert Einstein reached the idea of space-time, by studying two different principles of physics.įirst is Sir Isaac Newton's law of physics describing the motion of an object, which is based on the assumption that the laws of physics stay the same inside any given frame of reference.Īnd second is Maxwell's law of electromagnetic light which says that the speed of light is constant irrespective of its source.Įinstein applied rational logic on that, If these both theories are true, space and time have to be combined together. In his special theory of relativity, Einstein developed the idea of a single continuum of space-time in the year 1905. Great physician Albert Einstein has a great contribution in developing the idea of the space-time continuum. And that’s how space and time are related to each other. That is the idea behind the ‘space time’ phenomenon. Well, Earth is a tiny particle of infinite space…Now, what will happen, if we add time to that 3-dimensional space? If we add time to that 3-dimensional space then, it becomes a four-dimensional ‘Spacetime continuum’. You can say space is boundless If you want!

Void Between the sun and the earth, between moon and Earth, between Earth and Mars, and among all the celestial objects is called space, every object is situated in the void of space. Space is the void that exists between celestial objects. Space is a three-dimensional hollow area in which objects are situated.
