The video dives into one of the most common and mind-bending questions in cosmology: If the universe is expanding, what is it expanding into, and what is outside of it?
The prevailing scientific consensus is that the expansion of the universe is an intrinsic expansion—it's not expanding into a pre-existing empty space. Instead, it is the space itself that is stretching, causing galaxies that are not bound by gravity (like our local group) to move farther apart.
This means there is no "outside" to the universe because the universe is defined as everything—all of space and time. Thinking of it like dots on an inflating balloon helps visualize how every point moves away from every other point, but the surface of the balloon doesn't expand into anything and has no center or edge. This concept challenges our everyday intuition and introduces us to the true scale and nature of the cosmos.
