No quantum effects isnt the same as "space" travel, but they all kinda work the same.

Using quantum mechanics to defend relativity seems like a non-sequitur. Relativity has never been unified with quantum theory.

Math can even describe...Why would it be fake for the observable universe

There is more to physics than just math. Physics has physical concepts and models which can either be logically consistent or inconsistent. However even looking at pure mathematics, mathematician Stephan Crothers rips General Relativity to pieces from that perspective.
