One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed ...

Gravitational echoes may be caused by the collision of two black holes, and may indicate that these objects have completely new physical properties. This conclusion was made by RUDN physicists after a series of mathematical ...

(Phys.org) —Astronomers are asking volunteers to help them search for "space warps." More commonly known as "gravitational lenses," these are rare systems with very massive galaxies or clusters of galaxies that bend light ...
