The beginning of the universe is an exciting topic to explore. It’s not just for scientists, but for anyone who has ever wondered about how we got here.
The Big Bang theory is the most widely accepted scientific explanation of the early universe. The theory says that all matter in the universe was once concentrated in one infinitely dense point called a singularity. Right after the big bang, the universe was a hot soup of particles. It was dark, dense, and opaque because the free electrons would have caused the light (photons) to scatter the way sunlight scatters from the water droplets in the clouds.
But as time passed the universe continued to expand and cool and it became much less dense as the electrons began joining with nuclei and electrons collided less often with photons. Now with the electrons out of the photons way the path was clear for lights Great Escape 378 thousand years after the Big Bang. No matter how big or powerful our telescopes become the Cosmic Microwave Background is the oldest light we will ever be able to see.
But new observations from the James Webb Telescope are challenging our predictions. Whatever the Webb Telescope observed in the distant universe is completely denying our early universe model.
