One of the greatest and most complex works of Albert Einstein is General Theory of Relativity. It’s the case of relativity where the frame of reference is accelerating or decelerating (non-inertial frame). This is unlike Special Theory of Relativity, where we use the inertial frame of reference. But the most complicated work of Einstein wasn’t totally his own work.
THE ENTRY OF 4D SPACE EISTEIN’S GENERAL RELATIVITY:
It also took serious contributions from three great yet underrated mathematicians. They were namely, Jonas Bolyai, Nicolas Lobachevski, Bernhard Riemann.
What made Einstein seek other’s help in General Relativity?
General Theory of Relativity (GR) isn’t easy stuff. It’s full of mathematical and geometrical complications. However, the geometry that Albert needed to prove his theory wasn’t traditional Euclidian geometry that we use in school. Instead, it’s non-Euclidian geometry that he needed for his theory. At that time, the aforementioned mathematicians had published independently their own axioms or theories about their takes on non-Euclidian geometry. The work of Jonas Bolyai even got the attention of Gauss, a renowned mathematician back then. Jonas Bolyai presented his idea of non-Euclidian geometry in one of his lectures. He was very fortunate though as Gauss was also present in that lecture. He made the mathematicians and philosophers present in that hall imagine what 4-dimension can be.

Did It Help Einstein Anyway?
Yes, it surely did. The works of these mathematicians on 4D helped Einstein contemplate the fabric of spacetime from a unique perspective. It helped Einstein unify space and time as a single entity. Space and time won’t be written separately, instead they would be written as a single entity called spacetime. It also gave Einstein the idea of curvature of spacetime and also that time is the fourth coordinate in 4-dimensions. Another scientist who helped Albert was David Hilbert, one of the most influential mathematicians of the 19th century. Quantum mechanics uses Hilbert Space heavily to explain most quantum mechanical phenomena.
