Sep 29, 2020 · Some scientists believe its true size is even scarier than that. By using the Bayesian model averaging, scientists estimated that the Universe is at least 250 times larger than the observable Universe, or at least 7 trillion light-years in diameter.

What is the comoving distance from Earth to the observable universe?
The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs [32] (93 billion light-years or 8.8 × 10 26 m). [33] Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22 × 104 Gpc3 (4.22 × 105 Gly3 or 3.57 × 1080 m3).
Jan 28, 2022 · How big is the universe? Based on what we can observe, the universe appears to be almost 28 billion light-years across. However, it is far larger than that.
Jul 1, 2019 · How can the visible universe be 46 billion light-years in radius when the universe is only 13.8 billion years old?
So, how big is the observable universe? Well, it’s about 93 billion light-years in diameter. To give you an idea of what that means, a light-year is the distance light travels in one year, and light travels at a speed of 186,282 miles per second.
The Observable Universe is estimated to be about 93 billion light-years in diameter. That’s a lot of light-years! To give you a better idea, if you were to drive a car at a speed of 60 miles per hour, it would take you about 200 trillion years to drive across the Observable Universe.
Oct 26, 2022 · According to Bayesian mathematical models (designed to help us extrapolate ideas by looking at prior evidence that led us to our current knowledge), the whole universe is likely at least 470 billion light years across, and possibly much more, or even infinite.
