The term space-time was created by the mathematician Hermann Minkowski who, in 1908, mathematically proved that space and time cannot be separated from one another. Interestingly, he was the teacher of a certain Albert Einstein at the Polytechnic Institute in Zürich.
When in 1905, Minkowski heard about the development of the special theory of relativity by his former student, he apparently said: „I would not really have expected that from Einstein“. However, it was Einstein who set the biggest milestone in the research of space-time curvature so far in 1915, with his general theory of relativity.
