   How did scientists study the early universe?

   • Center for Astrophysics | Harvard & Smithsonian scientists study the early universe in a variety of ways: Hunting for signs of inflation using the twisting of CMB light called polarization. Even though this hypothetical rapid expansion of the universe happened a split-second after the Big Bang, it would have left observable traces behind.

   Why are astronomers studying the Dark Age?

   • Researchers are using the best observatories in the world both to study the dark age and to find evidence for the first stars in the universe. As the first stars and black holes formed, they turned much of the hydrogen gas in the universe into plasma again, a process astronomers call “reionization”.

   Why do scientists study the early epochs of cosmic history?

   • Despite those problems, the early epochs of cosmic history are essential for everything that came after, leading researchers to find ways to figure out exactly what happened when our universe was in its infancy. Center for Astrophysics | Harvard & Smithsonian scientists study the early universe in a variety of ways:

   What can astronomers learn from Webb?

   • In addition to studying previously shrouded stellar nurseries, astronomers can use Webb to explore an era known as the Dark Ages and the time immediately following it, the period of reionization. About 378,000 years after the Big Bang, as the universe cooled and expanded, electrons and protons began to bind together to form hydrogen atoms.
