Einstein's equations reveal how gravity could break, reconnect, and release energy

What happened

Researchers at Columbia University and Universidad Adolfo Ibáñez have identified a theoretical process called "gravitational reconnection," in which structures within gravitational fields can break apart and reconnect, transferring energy into matter. Under certain conditions, they undergo a sudden change in their connections, releasing stored magnetic energy into the surrounding particles.

This process powers solar flares and ranks among the most important mechanisms for releasing energy throughout the universe.

Their work suggests that gravitational fields can undergo a process in which their underlying structures break and reconnect, allowing energy to flow from gravity into matter. The phenomenon, known as "gravitational reconnection," bears an unexpected resemblance to a process responsible for some of the Sun's most powerful eruptions.

The discovery comes from Luca Comisso, an associate research scientist in Columbia University's Departments of Astronomy and Physics and the Columbia Astrophysics Laboratory, and Felipe A. Such insights are especially valuable in regions where gravity severely distorts space-time, making even the most powerful computer simulations difficult to interpret.

How Gravity Could Behave Like a Solar Flare The key to understanding this discovery lies in a well-known phenomenon called magnetic reconnection. Magnetic fields are often illustrated using curved lines, such as the patterns formed by iron filings around a magnet or the enormous magnetic loops extending above the Sun's surface.
