And some of the maths out there is abstract mathematics and not real. Take relativity, spacetime isn't real, its abstract, its just a mathematical tool, its just that it explains the properties of gravity to the best of our knowledge.

Yeah.
We like to call them mathematical models that describe how things behave.
As Swansont pointed out, the 'nature of reality' is a Philosophical question.

It's not a deeper insight into the nature of reality.

I don't think science has anything to say about "reality", just about what we can observe. Do you have a philosophical way of determining what is "real" or not? I can do a great deal with observations about a specific thing, and I can experiment with it and draw conclusions that I can base predictions on, but I don't have a meaningful way of determining if the thing is "real" or not. It seems real enough, and for my purposes that's all I need. 

I've seen the most outlandish claims when people start talking about "reality".
