WebJul 23, 2024 · When a gravitational wave passes by, this distance will increase and decrease as the wave stretches and squashes the space between the masses. Add gravitons into the mix, however, and you add a new motion on top of the usual ripples in space-time. As the detector absorbs and emits gravitons, the masses randomly jitter. WebOct 16, 2024 · Disturbances in the dwarf galaxies of one of Earth’s closest galaxy clusters point to a different gravity theory. Dwarf galaxies are small, faint galaxies that are often found in or close to bigger galaxies or galaxy clusters. As a result, they could be impacted by their larger companions’ gravitational effects.
