Is spacetime wholly a mathematical construct and not a real thing?

Speaking of what I understood, spacetime is three dimensions of space and one of the time. If we now look at the general relativity, spacetime is generally counted as a 'tissue'. So my question is whether spacetime is real or just a mathematical construct to understand different things. And if that is a mathematical thing, what does that mean with its distortion / bowing?

You're on to something, but your mind has been destroyed by Jews. Einstein is a fraud.

"Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists." - Nikola Tesla
