TED-ED: How small are we in the scale of the universe? - Alex Hofeldt

The video discusses the Hubble Telescope's observation of a dark sky area near the Big Dipper, capturing over 1,500 galaxies in a tiny universe sliver. It explains the scale of this image, comparing it to cosmic distances and the size of celestial bodies. The eXtreme Deep Field image, a result of over ten years of photographs, reveals galaxies so distant they're barely visible to the human eye. These images act as time machines, allowing scientists to study galaxies from over 13 billion years ago, shortly after the Big Bang. The video highlights the universe's homogeneity and encourages viewers to ponder the vastness of space.
