The mathematical model of the 20th century space-time continuum theory combines space and time into a single idea, where space is three-dimensional and time has the role of the fourth dimension.
The American author, poet and editor Edgar Allan Poe was one of the first to suggest that space and time were one.
In 1848 he wrote an essay of 90 pages on cosmology called “Eureka” in which he stated that time and space were one using no mathematics.
Apart from Poe, after some years H.G. Wells, Albert Einstein, as well as Hermann Minkowski dealt scientifically with this issue.
