Two neutron stars crashing into each other could produce a form of matter never seen before. If this happens, the simulations show that there will be a signal in the gravitational waves as a result of the collision

Gravitational waves may hold hints of a new type of matter

Gravitational waves created when two neutron stars collide may contain evidence of a never-before-seen type of matter made up of quarks.

Neutron stars form when massive stars run out of fuel and collapse. They are tightly packed neutrons, each containing three quarks held together by the strong nuclear force. When two neutron stars merge, their particles are so badly shaken that the quarks may be able to leave their neutron confinement and form a type of matter…
