Gamma ray bursts identified erupting from deep space have been found to exhibit some of the most bizarre galactic behaviour ever observed, scientists say.
The six extremely high energy bursts of electromagnetic energy, which were identified more than years ago, showed evidence of complex time-reversible wavelike behaviour – in which time itself appears to repeat backwards.
Scientists do not believe the behaviour is evidence of time travel.
Instead, they now think the repeating emissions are like a high speed release of charged particles that bounces around in galactic debris, like an echo.
This generates an unusual signal that is then further distorted by interference – or noise – over billions of light years, scientists say.
Understanding the phenomenon could help us understand more about the death of massive stars and even the formation of black holes.
