Topological structure has been extensively studied and confirmed in highly correlated condensed matter physics. We explore the gravitational waves emitted from the binary neutron star mergers using the pseudoconformal model for dense nuclear matter for compact stars which regards the topology change and the possible emergent scale symmetry and satisfies all the constraint from astrophysics. We find that the location of the topology change affects the gravitational waves dramatically due to its effect on the equation of state. And, the effect on the waveforms of the gravitational waves are within the ability of the on-going and upcoming facilities and therefore gives the possible way to measure the topology structure in nuclear physics.
