Pulsars are &#8220;pulsating stars&#8221; &#8211; objects with about the same amount of matter in them as our Sun, but squashed into a 20km ball. They spin very quickly (some a thousand times a second) and emit jets &#8211; creating a lighthouse type effect. These two not only spin, but rotate around each other every 2.4 hours. One spins 45 times a second, the other every 2.8 seconds. They are very chaotic, and will collide in 85 million years, maybe turning into a black hole. By analysing them we can check many of Einstein&#8217;s theories of General Relativity, which help us understand how the Universe works.<\/p>\n<p>The piece is named after the slower pulsar, PSR J0737-3039B, or alternatively &#8216;ds squared &#8211; series 1&#8217;, reflecting some of the 4 dimensional geometric properties used in this field.
