Quantum Mechanics - Could You Have No Space?

In quanta mechanics, we have no description of the curvature of space that works. Memmer gravityis so much weaker than all the other forces, like ten to the 30 times weaker. We can't really test these things secause all the other forces dominate. So there are now really fun ideas about how space might not be fundamental and you could have a universe without space in quant mechanics.
