are among some of the most mysterious objects in the Universe. They are the remnants of massive stars that have reached the end of their life cycles and collapsed into a region of spacetime that is incredibly dense. Their gravitational force is so strong that nothing can escape their surface.As such, they have thus far not been considered a great source of information for physicists.
by the institution. From this data, they plan to deduce how the Universe evolved, what it is made out of, and where it’s going.This new technique has been called the “spectral siren,” and it may just be able to tell us about the early misunderstood “teenage” years of the Universe.
