Web16 de jul. de 2024 · The big question: In combining that data, astronomers are searching for clues about how the first galaxies ever formed. One theory suggests early galaxies were born from massive clouds of gas and dust that collapsed in on themselves, creating dense clouds that began to coalesce and spin — forming galaxies. WebThe answer is that because light travels at a finite speed, the light from some things that we see now left them millions of years ago. And because the Universe is expanding, light such as this is redshifted; the more redshift, the longer the light has traveled to reach us. By observing very high redshift objects, we can look back in time.
