This wasn’t considered a problem because all the theoretical and observational evidence suggested that pulsars spin several times per second

The theory attempted to explain a number of strange, so far unexplained sources of gamma rays called Soft Gamma Ray Repeaters (SGRs). These distant objects unpredictably emitted strong bursts of gamma rays, quietening down over a matter of seconds, and then remaini
