LISA is set to revolutionize our understanding of the gravitational universe and the interactions that make the entire cosmos ...

Abstract: We determine the response of a self-similar isothermal stellar system to small adiabatic gravitational perturbations. For odd spherical harmonics the response is identical to the response of ...

They suggest that as gravitational waves continued to amplify and collide, this led to conditions where small disturbances in space (scalar perturbations) become much larger than gravitational waves.

The examination of parity symmetry in gravitational interactions has drawn increasing attention. Although Einstein’s General Relativity is parity-conserved, numerous theories of parity-violating (PV) ...

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of spacetime called gravitational waves, first proposed by Albert Einstein ...

Orbital elements for newly discovered comets need to be added with the Solar System Editor plugin, and elements for existing comets may need frequent updates: Stellarium does not simulate orbital ...
