The Unfathomable Expanse of the Universe
The vastness of the universe is unimaginable, with distances between celestial objects spanning billions of light-years. Even our solar system, on a scaled-down model, is mind-bogglingly large. The Milky Way is just one of over 100 billion galaxies, and the universe's diameter is estimated to be at least 93 billion light-years. It is possible that the universe is infinite in size, and its expansion is accelerating over time. The immense distances make it highly unlikely for us to encounter extraterrestrial life in our daily lives.
