about how big was the universe at this time?

But the exact reasons why it happened are still being explored. Eventually, the observational evidence began to favor Big Bang over Steady State. [38] Around or shortly after 47,000 years, the densities of non-relativistic matter (atomic nuclei) and relativistic radiation (photons) become equal, the Jeans length, which determines the smallest structures that can form (due to competition between gravitational attraction and pressure effects), begins to fall and perturbations, instead of being wiped out by free streaming radiation, can begin to grow in amplitude. the CMB, the edge of what we can see) and become invisible to us. Every time in history we reach the limits of our understanding, some morons pipe up that God did it and that we will never understand so we shouldn't even try. Karla Thompson – @karlaii / https://www.youtube.com/channel/UCEItkORQYd4Wf0TpgYI_1fw As of 2019, the earliest confirmed galaxies date from around 380–400 million years (for example GN-z11), suggesting surprisingly fast gas cloud condensation and stellar birth rates, and observations of the Lyman-alpha forest and other changes to the light from ancient objects allows the timing for reionization, and its eventual end, to be narrowed down. (More exactly, any composite particles that form by chance, almost immediately break up again due to the extreme energies.). The Bolshoi Cosmological Simulation is a high precision simulation of this era. Events = Coming into existence , Existing and End of existence . The size of the universe means the space in which we can interact with anything. Why do people argue that they are right? These particles include almost equal amounts of matter and antimatter, so most of it quickly annihilates, leaving a small excess of matter in the universe. I would appreciate you not making the assumption that, because I read the Bible, I am incapable of serious thinking. We don't know what or who or why and we probably never will but what we do know is that your book was a story created by mere men who used it and 'God' to create fear in people so as to have control over them. A mystery to be solved and nothing more. If it does, we obviously can't see it yet. I have just logged in and am very happy to join you all folks. It would be expected that both baryons, and particles known as antibaryons would have formed in equal numbers. the problem here is that everyone thinks with a mind that deals with everything having a beginning and an end. Of course there are several things that still need to be worked out with our cosmological models. The photons released by these newly formed hydrogen atoms initially had a temperature/energy of around ~ 4000 K. This would have been visible to the eye as a pale yellow/orange tinted, or "soft", white color. There is no hard evidence yet, that such a combined force existed, but many physicists believe it did. When we look out into the universe, 23:22 Why didn't the Universe collapse again? Not only does the model explain the origin of all known matter, the laws of physics, and the large scale structure of the Universe, it also accounts for the expansion of the Universe and a broad range of other phenomena. None of us can be certain of anything and to act like we are certain makes us just as dumb as the people who once said "the earth is flat.". They are abundant in numbers, do not collapse under their own gravitation, nor do they expand without limit. man won't, but the universe will. Join us at patreon.com/universetoday. About 25% of the protons, and all[24] the neutrons fuse to form deuterium, a hydrogen isotope, and most of the deuterium quickly fuses to form helium-4. As a result, the universe was opaque or "foggy". They therefore grew even denser, forming gas clouds, stars, galaxies, and the other astronomical structures that we regularly observe today. It was hard to continue with the rest of the article with those two immediate errs sticking in my head. infinity – infinity = infinity. [56] The current leading candidates from most to least significant are currently believed to be Population III stars (the earliest stars) (possibly 70%),[57][58] dwarf galaxies (very early small high-energy galaxies) (possibly 30%),[59] and a contribution from quasars (a class of active galactic nuclei).[55][60][61]. Space was never created; it already existed, Scientists should try to unlock the question of how space is created and when they say space was created by big bang, I have an obvious question - where did big bang came from or whatever constituted big bang, either the protons or atoms, where did those come from? Little is understood about physics at this temperature; different hypotheses propose different scenarios. A 1:7 ratio of hadrons would indeed produce the observed element ratios in the early as well as current universe. outside of the universe . Yet we find that they of inflation is to moderate the density of the universe to make space appear The only logical answer is God. It was bestowed upon our prophets. There are passages in the Bible that speak of the earth as being round. Galaxy clusters and superclusters emerge over time. The discovery and confirmation of the cosmic microwave background radiation in 1965 secured the Big Bang as the best theory of the origin and evolution of the universe. This period, known as the Dark Ages, began around 370,000 years after the Big Bang. anon86394: You ask, "The Bible says that God created day and night on the first day, but the sun and moon weren't created until the fifth day. What you see is what you get, and as long as space is excluded as a real quantity, physicists will never put it together. However I find your last statement to be truly insulting. Since space isn't matter or energy there's no limit to how fast such a pocket could move. When the universe was only 1 millisecond old, nuclei were hot enough and dense enough to fuse to create heavier elements, but it was so dense that the nuclei broke apart again as soon as they formed. Void or Zero is artificial and exists only in designations or descriptions . They show that reionization began as "bubbles" of ionized hydrogen which became larger over time. So to get 156 light years, start 14 billion light years away and send a beam of light. Then, from 10-36 to 10-32 seconds after the Big Bang, the temperature of the universe was low enough (1028 K) that the forces of electromagnetism (strong force) and weak nuclear forces (weak interaction) were able to separate as well, forming two distinct forces.
