What is outside the expansion of the Universe?
The universe does not expand into anything because, as far as any evidence we have goes, it is everything that exists. In other words, there is nothing outside of the universe. The question starts with an incorrect assumption – that the universe has as “edge”, a boundary between “universe” and “non universe”.
Is there an outer limit to the Universe?
But if you define it as the limits of the unobservable Universe, the only limit we have is that it’s at least 11,500 billion light-years in size, and it could be even larger. This doesn’t necessarily mean that the Universe is infinite, though.

What are the limits of the universe?
There’s a few different horizons that you could use to define the relevant limits of the universe, but the most often cited number is that the radius of our universe is on the order of 45 billion light years, which is about 1 2 times Avogadro’s Number in kilometers. That’s slightly farther than Usain Bolt can run in an hour.
What lies outside of our universe?
And outside of our universe might lie a much bigger universe. We’re merely confined in a black hole inside of it. Another theory suggests that the not yet observable part of our universe contains more universe. Nothing else. More stars, galaxies, and clusters in an infinitely expanding space.
What determines the boundaries of the universe?
The boundaries of the universe are determined by the boundaries of the dimensions. In Cartesian coordinates, the universe goes as far as x, y, and z does and exists at every moment to which a value for time can be ascribed. So if there are limits to the universe, that must be because there are limits to x, y, and z.
How many light years are there in the universe?
These 93 some-odd billion light-years contain all of the quarks, quasars, stars, planets, nebulae, black holes…and everything else that we could possibly observe; however, the observable universe only contains the light that has had time to reach us. A lot more universe exists beyond what we are able to observe.
