Does the multiverse exist? Scientists present first evidence
Between 1912 and 1922, astronomer Hubble measured the spectra of many galaxies and found that their spectra were all redshifted, meaning they were moving away from Earth. In 1929, Hubble compiled the observational data and published his results that the farther away galaxies are from us, the faster they are receding, which means that the universe is expanding. Later, many scientists reversed Hubble's law and discovered that there is a starting point for the universe, that is, the Big Bang.

How do black holes eat stars? Scientists show the whole process of phagocytosis time and time again
Black holes are the most mysterious celestial bodies in the universe. Scientists have been trying to solve the mystery of black holes since the last century. Due to the strong gravity of black holes, even light cannot escape, so people cannot directly observe the true situation of black holes. The glowing material accretion disk around the black hole is used to observe the black hole. Usually, the accretion disk around the black hole is composed of torn stellar debris. However, the process of the black hole swallowing the star has always been only in the theoretical stage.
