A singularity—a point of infinite density and temperature—contained all of the universe’s matter and energy around 13.8 billion years ago. The fast expansion of this singularity is today known as the Big Bang.
The basic forces of nature, including gravity, electromagnetism, the weak force, and the strong force, started to manifest in phases during this explosive birth. Because of this, it all seemed too odd when the JWST discovered several galaxies that appeared to skip some of those phases.
For what reason do these galaxies predate the universe? Were they around prior to the Big Bang?
The universe was just 500–700 million years old when these galaxies were discovered, which is about 3% of its current age. The majority of theories at the time anticipated the formation of tiny, newborn galaxies since the cosmos was still in its infancy.
These recently discovered galaxies are far from little, though. Their stellar mass is many billions of times greater than that of our sun. It is possible that one of them may be 100 billion times more enormous than our sun. To put this into perspective, there are about 60 billion suns’ worth of stars in our own Milky Way galaxy.

Red-shifting must be examined in order to comprehend this. Telescopes detect a different color depending on how ancient the body is in the cosmos. When the color turns red, the galaxy’s age may be determined by comparing the amount of red.
These galaxies’ redshifts reveal not only how old they are, but also how big and full of massive stars they are.
