Universe is vast from "summary" of Space Encyclopedia by David A. Aguilar,Christine Pulliam,Patricia Daniels
The Universe is an immense and expansive space that stretches far beyond what we can see with our naked eye. It is filled with countless galaxies, each containing billions of stars and planets. The sheer size of the Universe is almost incomprehensible, with distances measured in light-years - the distance that light travels in one year, which is about 6 trillion miles. Our own galaxy, the Milky Way, is just one of billions of galaxies in the Universe. Each of these galaxies is home to its own unique set of stars, planets, and other celestial bodies. The Universe is constantly expanding, with galaxies moving away from each other at incredible speeds. The vastness of the Universe can be difficult to grasp, as our human minds are not equipped to truly comprehend the scale of it all. Despite our best efforts, we can only scratch the surface of what lies beyond our own solar system. Scientists use powerful telescopes and other tools to study the Universe, but there is still so much that remains unknown. The Universe is a place of wonder and mystery, with endless possibilities waiting to be discovered. It is a reminder of how small we are in the grand scheme of things, and yet how connected we are to everything around us. As we continue to explore and learn more about the Universe, we are constantly reminded of just how vast and awe-inspiring it truly is.
