 And became billions of times stronger than our sun's, now as the star span, it channelled out radio signals from its north and south poles, signals that swept past earth with every rotation 1 of the star, this was the source of the mysterious pulses, some are so regular that pulsars are among the most accurate clocks in the universe, the discovery of neutron 2 stars was a vindication 3 of the power of theoretical physics, it set astronomers 4 wondering if other strange bodies that had been predicted could be lurking 5 in space, and there is one hypothetical object that was even weirder 6 than a neutron star.

For years most scientists dismissed black holes as fanciful conjecture 7.
