Fast radio bursts are millisecond-duration flashes of radio energy first detected in 2007 at Parkes Observatory, Australia, that release more energy than the Sun produces in 3 days, yet occur in just 0.001 seconds; over 600 have been cataloged from distances up to 8 billion light-years, with some sources repeating over 1,000 times, though the physical mechanism generating these bursts remains unconfirmed despite magnetars being the leading explanation.

Something Billions of Light Years Away Releases More Energy Than 3 Days of Sunlight in 0.001 Seconds追加:
In 0.001 seconds, a burst of radio energy reaches Earth from billions of light-years away, releasing more energy than the Sun produces in 3 days. It happens thousands of times a day. Fast radio bursts, first detected November 2007 by Duncan Lorimer at Parkes Observatory, Australia. The signal had been waiting 6 years to be found.
Over 600 cataloged sources traced up to 8 billion light-years away. Each one brighter than an entire galaxy for a millisecond. One source is repeated over 1,000 times. Magnetars are the leading explanation. Magnetar models cannot explain the repeating pattern.
Compressing 3 days of solar energy into a millisecond repeatedly requires a physical process that has not been identified. Astrophysicists confirm the energy, the repetition, the distance.
The mechanism is still unknown.
Something out there keeps firing. We cannot explain what it is.
