In this video, we discuss the groundbreaking discovery made by the James Webb space telescope, which has detected what appear to be six massive ancient galaxies, dubbed "universe breakers" by astronomers due to their size and potential to upend current theories of cosmology. These galaxies date back to a time when the universe was just 3% of its current age and are far larger than was previously thought possible for galaxies so early after the big bang.
The discovery challenges scientists' understanding of how the earliest galaxies formed and could potentially call into question the validity of the Big Bang theory. The James Webb telescope's infrared-sensing instruments have been able to detect light emitted by the most ancient stars and galaxies, allowing scientists to study the early universe in more detail than ever before.
Join us as we explore the implications of this discovery and discuss what it could mean for our understanding of the universe's origins. Don't forget to like and share this video and subscribe to our channel for more news and discoveries in space and astronomy.
