Physicists Luca Comisso and Felipe A. Asenjo calculate that Einstein's equations allow gravitational fields to break and reconnect like solar magnetic fields, a process they call gravitational reconnection that could transfer energy to matter.
Einstein's equations reveal an unusual new way space-time can transfer energy, according to recent science coverage.
Recent theoretical studies reveal that gravitational fields can break and reconnect in space, mirroring solar magnetic lines.
Researchers have observed a falling atom obeying Einstein's gravity rule within the quantum world for the first time.
Physicists have successfully observed quantum objects obeying gravity by sending 20,000 atoms into free fall, validating a prediction from 1927.
