[00:00:05]A starry sky [music] with sudden flashes of light.

[00:00:09]Imagine a signal from billions of light-years away lasting less than a blink of an eye >> [music] >> yet carrying the energy of our sun's output over several days.

[00:00:21]These are fast radio bursts or FRBs, one of astronomy's greatest [music] mysteries.

[00:00:30]What they are, radio waves traveling across space.

[00:00:39]FRBs are intense bursts of radio waves detected by giant radio telescopes.

[00:00:46]They last only milliseconds to a few seconds but they're so powerful that even across the universe, we can still pick them up here on Earth. [music] >> [music] >> The first FRB was discovered in 2007 by Duncan Lorimer and [music] his student David Narkevic.

[00:01:11]Since then, astronomers have detected hundreds. Some repeating in strange patterns.

[00:01:17]>> [music] >> Others appearing just once.

[00:01:20]Theories, where do they come from?

[00:01:23]Theories range from magnetars, neutron stars with magnetic fields >> [music] >> trillions of times stronger than Earth's to colliding black holes or neutron stars. [music] Some even speculate exotic physics or advanced civilizations. [music] But the leading evidence points to extreme astrophysical events.

[00:01:45]Why do they matter?

[00:01:47]FRBs used as cosmic beacons >> [music] >> mapping galaxies.

[00:01:52]FRBs aren't just mysterious, they're useful.

[00:01:56]They act like cosmic flashlights, >> [music] >> helping astronomers map matter between galaxies and understand the universe's hidden structures.

[00:02:07]Fast radio bursts [music] remind us how much we still don't know. Each detection is a clue, bringing us closer to solving one of the universe's >> [music] >> loudest secrets.
