Describes behaviour of particles at a cosmic scale = big things like warping of space & time
Describes behaviour of particles at an atomic scale = small things like atoms & electrons

All the fundamental particles at the cosmic / atomic scale obey the laws of these theories – except gravity.
Both theories and their relation to gravity are needed to explain what happens inside black holes and the big bang.
But both disagree on how gravity works, leading to paradoxes and things like singularities, where the theories break down.
--singularity: a point at which a function takes an infinite value, especially in space–time when matter is infinitely dense, such as at the centre of a black hole.
