12 Νοε 2016 · The measure in the middle of the image represents 1.5 billion light years. light travels in every direction, and at the time of the big bang, there was no light to travel anywhere, and early in the theory of the big bang, there were no 3D directions that we can conceive, no definition of straightness and edge, no distance in between anything in ...
18 Μαΐ 2014 · Whether the big bang is a theory or a model, it cannot be "proved". Scientific models and theories can only be falsified. I think what you mean is - are there other pieces of evidence that are used to support the big bang model? Or possibly are there other pieces of evidence that support the idea that the universe was once very small and very hot?
14 Απρ 2021 · In the Inflation theory, it said that the Inflationary epoch has happened $10^{-32} \,\mathrm{s}$ after the Big Bang, and I cannot find anything related to how this number was calculated and how ... big-bang-theory
21 Φεβ 2016 · "A few minutes into the expansion, when the temperature was about a billion (one thousand million) kelvin and the density was about that of air, neutrons combined with protons to form the universe's deuterium and helium nuclei in a process called Big Bang nucleosynthesis. Most protons remained uncombined as hydrogen nuclei.
19 Δεκ 2016 · But to be more specific what I really don't understand are the implications of this result and if this result would invalidate some current cosmological theory and why. I've heard it might have some implication on Quasar formation and change the current timeline of the Big-bang but didn't get how nor why. Can anybody give me some hints?
18 Μαρ 2017 · The Planck epoch was the earliest epoch of the Universe and lasted until $10^{-42}$ seconds after the Big Bang — that's 200 Planck times, which are the shortest meaningful measurement of time. During this epoch, the entire Universe was at $1.417×10^{32} \; \mathrm{K}$ , which is the Planck temperature.
7 Ιαν 2016 · The Big Bang did not happen at a single point, nor did the Universe begin at a single point. The Universe is, and has always been, infinite. The Big Bang was just when the Universe's expansion really began — that is, when objects started drifting away from each other. The Universe was still infinite, but there was less space between the matter.
5 Νοε 2013 · Since, supposedly the Big Bang started with a very tiny singularity blob (at least for this theory), smaller than a marble, then there ought to be various vector trails (even if they are fragmented or somewhat askew, blurred or dissipated) of some sort going back to the marble size singularity state or at least into the outward edge area of the 'super' iflation phase (especially since matter ...
12 Μαρ 2021 · In the Big Bang Theory, there's a map on Sheldon & Leonard's refrigerator throughout the entire show It has false-color shadings of various kinds, with prominent craters, and so is presumably of some non-terrestrial body, perhaps Mars, the moon, or an asteroid.
Much faster than normal expansion due to Big Bang. It was an exponential expansion and occurred around ${10}^{-32}$ seconds after Big Bang and lasted for tiny fraction of second. The universe continues to expand but not at that exponential rate. Yes it is still a theory and is accepted by many scientists.
