Right after the Big Bang, gravitational waves may have built on each other to create huge standing waves of gravitational energy.

If I let the gravitational potential energy at an infinite distance be zero Joules, then: Yes, the gravitational potential energy in this way would always be negative.

A massive clump of dark matter in the Perseus galaxy cluster is linked to its core by a bridge of dark matter, evidence of a history of mergers.

A century after Albert Einstein predicted their existence, gravitational waves have finally been detected, tiny ripples in the fabric of space-time that were generated when two massive black holes ...

Supermassive black hum: Scientists discover gravitational wave background that permeates universe The source could be merging black holes — or something more 'mind-bending' ...

Energy forms - CCEA Higher tier: Gravitational potential energy Energy cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

In National 5 Physics investigate the conservation of energy law; examine how gravitational potential and kinetic energy relate when items fall from height.

The latest LIGO signal proves that gravitational waves travel at the speed of light, ruling out a swath of cosmological theories in the process.

In 1999, however, the newly discovered cosmic acceleration made it clear that some form of anti-gravitational energy (perhaps similar to Einstein's cosmological constant) had to exist.
