| β | {{w|Pulsars}} are rotating neutron stars, which have a very precise period of rotation. Pulsars are highly magnetized, causing them to emit a beam of electromagnetic radiation that rotates across their sky. {{w|Radio astronomy|Radio astronomers}} can detect these beams if and when they point towards Earth, where they appear as pulses of radiation with highly stable periods. They use the pulsars' periodic beams to try to detect {{w|gravitational waves}} by tracking the rotation period of an ensemble of pulsars extremely precisely over long periods of time. Disturbances in the pulsars' rotation period will be measurable at Earth. A disturbance from a passing gravitational wave will have a particular signature across the ensemble of pulsars, and will be thus detected. The process is called {{w|Gravitational_wave#Using_pulsar_timing_arrays|"pulsar timing"}}, or just "timing" for short. | + | {{w|Pulsars}} are rotating neutron stars, which have a very precise period of rotation.

[[Ponytail]] presents this to [[Cueball]] as a joke - specifically, a joke about comedy. One of the most important aspects of comedy is revealing the punchline with correct timing. Ponytail sets Cueball up for a joke like, "Ask me what the secret of comedy is." / "What's the secret of--" / "Timing!" In this format, the punchline ("Timing!") deliberately comes too soon, which makes it funny because the timing is bad. Ponytail also replaces the secret to comedy with the secret to detecting gravitational waves with pulsars, to set up the joke about the word "timing". | [[Ponytail]] presents this to [[Cueball]] as a joke - specifically, a joke about comedy.
