What Really Happens At The Universe’s End?

Although the flat Earth theory may not be entirely true, the universe may be considerably flatter than you imagine. Einstein’s theory of general relativity, which states that the speed of light remains constant no matter how distorted spacetime gets owing to the gravitational attraction of things like stars or black holes, supports the idea of a geometrically flat, infinite universe. It’s also the most logical explanation, given that the entire quantity of “universe” in existence is determined by an event horizon — a boundary through which no light can escape — that is constantly expanding in all directions at a rate significantly faster than the speed of light (via Explaining Science).

According to a blog post by West Texas A&M University’s Dr. Christopher S. Baird, what we can really see is steadily increasing as well, albeit at the speed of light, which is finite in comparison to the speed at which the aforementioned cosmic event horizon is expanding. The speed of light is 983,571,056 feet per second, according to space. This is because the observable universe (which has a radius of about 45 billion light-years) expands at a different rate than the cosmos itself, which scientists are still trying to define or conceptualize as a geometric entity. The boundary of the cosmos is defined by a “particle horizon,” which is analogous to the event horizon of a black hole but reversed. However, it’s critical to realize that the “edge” of the cosmos does not exist in the way that you might believe.

There Isn’t Really An Edge To The Universe

You might imagine the “edge” of the universe as a place where you could spin around and see a zoomed-out perspective of everything, including every galaxy, planet, star, and so on. But, according to Space, this isn’t the best way to approach this topic, because even if you caught up with the edge, there would simply be more universe. This isn’t necessarily an issue that can be solved by picturing the entire universe as some kind of object or point of observation, according to the theory; it just is.

Instead, imagine being able to step outside of the world and holding the full contents of it in your hand. You’d probably have a sphere-shaped object in your hands that maintains the same size as the contents inside shift about, but because the universe is self-contained (much like a video game environment), we’d never be able to genuinely become aware of an outside, at least not without interdimensional travel.

Furthermore, as the universe expands (again, faster than the speed of light), the distances between objects in space expand as well. It’s possible that entire galaxies are flying faster than the speed of light away from our own location in spacetime. So, rather than “what really happens beyond the edge of the universe?” the essential question would be “what’s beyond our observable universe?” — which, as astrophysicists at the University of Lyon postulated in 2021, is just more universe.
