universe, which can be compared with the sounds of a bass, used the method proposed by our scientist mikhail sazhin for this. in his article back in 1978, he put forward the idea of registering the effects of gravitational waves, with the help of radio pulsars in the universe, there are millisecond pulsars, objects with a mass of about the sun and the size of a large city, they rotate at a speed of 1,000 revolutions per second or more and descend radio waves in the form of a narrow beam, like a beacon, they are fixed by radio dishes if there are changes in the signal that come from pulsars, there must be a reason for it; this method of getting to the bottom of the reason is called pulsar timing. no, very witty. he's very simple. so, let's imagine that you have such a watch, right? which is ticking give you a periodic signal, what kind of clock can serve? pulsars, when an aggregation wave from some source comes, it shifts a little. uh, well, it shifts, so to speak, uh hmm, and the detector is there and the pulsar too. well, in general, you are going through some changes, as if the distance from
