What lies beyond the expanding universe? | Space Documentary 2025
As incomprehensibly vast as the universe already is, scientists keep revealing something even more astonishing: the universe is expanding. But what does that really mean?

Galaxies are drifting away by moving through space, but because the space between them is growing. So, if the universe truly expands, what exactly is it expanding into?

Dive in with us as we unravel one of the deepest mysteries in cosmology and explore the vast unknowns of the expanding universe..
