- podiki 10y agoThe "Fast" in Fast Radio Bursts is because the signal lasts only milliseconds, while the Wow signal lasted thousands of times longer, for over a minute.
- drjesusphd 10y agoWhoa, really?
- podiki 10y agoYup. If you look on the Wikipedia article for the Wow event, it lasted for the entire observing window, so that implies it could have lasted longer before/after. Meanwhile FRBs are quite amazing because they are so quick. It's a lot of energy in a very small time, which leads people to consider compact objects as part of the origin (short burst leaves very small distance from the light travel time for the event to be coherent).
