Jun 19, 2015 · And of course, we are talking only about the observable universe — the part we can actually see. But the best estimate now is that there are between 100 billion and 200 billion galaxies in the ... This is not a theory just a question, I was wondering about relative sizes. People often talk about what was before the Big Bang, Or what our universe is expanding into...Size of the observable universe. The size of the visible or observable universe encompasses everything that man has discovered and known, as well as matter, energy, space and time.It is believed that the universe is so large that we cannot even have a rough idea of its size.
The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8 × 10 26 m). 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 ). Based on what we currently think about inflation, this means that the Universe is at least 10^(10 30) times the size of our observable Universe! And good luck living long enough to even write that ...This quantity refers to the distance to the particle horizon, r p, i.e. to the radius of the observable universe. The diameter would be twice as large. proper radius of the observable universe = r p ≈ 46 G l y. This can be calculated similarly to calculating the age of the universe as shown above.
