This concept helps explain how gravity works in the universe.
When did albert Einstein discover gravity?
Albert Einstein did not discover gravity; rather, he developed the general theory of relativity in 1915, which revolutionized our understanding of gravity as a curvature of spacetime. This theory explains how massive objects like planets and stars warp the fabric of spacetime, causing the force of gravity.
How does the concept of space vs time influence our understanding of the universe?
The concept of space vs time influences our understanding of the universe by shaping how we perceive the relationships between objects and events. Space and time are interconnected in the theory of relativity, where they form a four-dimensional framework known as spacetime. This framework allows us to understand how objects move and interact in the universe, and how gravity affects the fabric of spacetime.
