A new theoretical framework shows that tidal forces in inspiraling neutron star pairs can be described through oscillation modes, opening a new path to studying ultra-dense matter using gravitational ...
And in one of the most remote corners of the planet, beneath Antarctica, gravity is at its weakest. In a new study published ...
