Precise measurements of neutron star mergers provide unique insights into how matter behaves at densities far beyond anything achievable on Earth. By analyzing tidal deformations in gravitational-wave signals just before collision, scientists can probe the compressibility and equation of state of neutron-star matter.

These observations rule out overly soft or stiff nuclear matter models, showing that neutron stars are governed by strong nuclear forces under extreme pressure. Each detected merger turns cosmic collisions into natural laboratories, linking astrophysics with fundamental particle physics.
