Scientists generally split this into three distinct concepts: what is beyond our sight, what is beyond the physical fabric of space, and what might exist as a "super" structure. 1. Beyond the Observable Universe

: Measurements suggest the universe is "flat" like an endless sheet of paper. This implies it may be infinite in extent , with no physical edge at all. 2. Beyond the Fabric of Space-Time

If the universe is finite, it doesn't necessarily have a "wall." Instead, it might be curved like the surface of a sphere. Beyond the universe

: Most cosmologists believe that if you traveled past this "horizon," you would just find more galaxies and stars stretching on forever.

: In this model, if you travel in one direction long enough, you eventually end up back where you started . There is no "outside" because the fabric of space-time itself is all that exists. When asking "what lies beyond the universe," the

The observable universe is a sphere around Earth containing everything we can currently see. Because light has a speed limit, we can only see objects whose light has had time to reach us since the Big Bang (about 13.8 billion years ago).

: This theory proposes that infinite other universes exist, perhaps with different laws of physics. Beyond the Observable Universe : Measurements suggest the

: Our universe could be an isolated "island" floating in a higher-dimensional "super-universe". What's Beyond The Observable Universe?
