Fast radio bursts are like bubbles in a boiling soup: they pop without rhythm. These short blasts of radio waves from distant galaxies release as much energy in milliseconds as the Sun does in days. The signal travels to us at the speed of light for billions of years, stretched out by the expansion of the Universe and Einstein’s time dilation.
Astronomers measured the disorder in their signals, comparing them to events from solar flares to earthquakes. Among the suspects are supernovae, which leave behind neutron stars (predicted by Zwicky, with a mass limit from Chandrasekhar), and pulsars — rotating lighthouses discovered by Bell Burnell. The usual explanations didn’t fit.
On the stochasticity–chaos graph, the bursts stood out as outliers. Their chaos is unique: the signals arise in the turbulent environment of a neutron star, independently of each other. One source produced over 10,000 bursts in 8 months, flashing up to 12 times per second — faster than a hazard alarm. The method applies to mergers of black holes and gravitational waves. Dark matter is on the list of other mysteries.
🎯 A single millisecond burst radiates as much energy as our Sun does in several days. And some repeaters flare so often that in a month they release more energy than the Sun does in thousands of years.
🎬 In Carl Sagan’s novel "Contact", a radio signal from space became the key to communicating with an extraterrestrial civilization. Fast radio bursts, discovered later, were also initially considered possible artificial signals, but today scientists see them as a natural wonder.
