Fast Radio Bursts Explained
A fast radio burst is a transient radio wave from deep space. The bursts last only milliseconds. Duncan Lorimer and his student David Narkevic found the first one in 2007.
What the video says
A fast radio burst is a transient radio wave from deep space. The bursts last only milliseconds.
Duncan Lorimer and his student David Narkevic found the first one in 2007. They searched through old pulsar survey data.
The Parkes Observatory recorded that original signal on 24 July 2001. Archival data has the urgency of a filing cabinet.
Most fast radio bursts happen once. FRB 180916 repeats every 16.35 days, which is unusually polite.
Fast radio burst signal strength is extremely faint on Earth.
In April 2020, the CHIME radio telescope detected a fast radio burst inside the Milky Way. Magnetars are just being loud in their own apartment.
FRB 121102 comes from a galaxy roughly three billion light-years away. The host environment is extreme.
Proposed origins include merging black holes, neutron stars, or extraterrestrial intelligence. Little green men still haven't returned their calls.
