Web11 de abr. de 2024 · Detailed measurements of the expansion rate of the universe place the Big Bang singularity at an estimated 13.787±0.020 billion years ago, which is considered the age of the universe. Web15 de abr. de 2016 · The Planck density is around 5*10^96 kg/m^3. So to squeeze the observable universe to the Planck density, you'd have to divide its volume by about 6*10^122. Since the volume of a spherical region is the cube of its radius, we have to take the cube root of this to find how much to divide the radius, or 8*10^40.

Web15 de jan. de 2015 · If you take the big bang theory seriously, its size would have been identically zero. That's what the singularity means. And that's why it's nonsense. In order to get an answer different from zero, you have to make use of another model, such as inflation or the LQC bounce. Take the radius of the current observable universe. Webbig bang singularity as the Borde-Guth-Vilenkin theorem proves [104].
