What do we know about radio waves? We might think that
they are from stars, but what about those from those of dead stars?
“The radio waves we see from pulsars have a mysterious
glitch – but now we know the ingredients that must be present in the heart of
these ultra-dense stellar corpses to give their emissions a hiccup.
About 60 years ago, researchers noticed that the radio
emissions from pulsars can suddenly and unexpectedly change in 4,6, frequency, indicating that the pulsar’s
rotation slowed down.”
