Nothing in the universe can travel faster than the speed of light — so how can there be parts of the universe that light may never reach? In this video, we explore the true size of the observable universe, why a universe only about 13.8 billion years old can be roughly 92 billion light-years across, and how the expansion of the universe creates cosmic distances that even light cannot overcome. We’ll travel from Earth and the Milky Way to the edge of the observable universe, uncover why distant galaxies can effectively recede faster than light without violating Einstein’s relativity, and reveal the difference between what we can see and what we could ever reach. We’ll also explore the cosmic event horizon, dark energy, accelerating expansion, and why some galaxies visible today may eventually disappear beyond our reach forever. The speed of light may be the ultimate speed limit — but in an expanding universe, even that may not be enough. Visit our website for up-to-the-minute updat
