23 de abr. de 2014 · In the standard ΛCDM model of the Big Bang, the universe is infinite and has always been such. The Big Bang singularity happened everywhere, in the sense that far back enough in time, the density diverges to infinity at every place. But this is just a particular model--it assumes that the universe if spatially flat and is globally homogeneous ...
12 de nov. de 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 ...
But after the universe had cooled (it took sometime between 10−36 10 − 36 and 10−32 10 − 32 seconds) the weak and electromagnetic fields split, and the first true photons formed. These photons didn't get very far before colliding with other particles that were being formed. As you note, it took nearly 400000 years until the universe ...
Following the Big Bang the Universe continues to expand, presumably and roughly equally in all directions. It is understood that the Big Bang occurred 13.798 ± 0.037 billion years ago. Is there any way for us to know how far we are away from the nearest edge of the expansion front of the Big Bang? universe. big-bang-theory.
19 de out. de 2015 · We say that our universe is 13.7 billion years ago. During the big bang, it doubled at least 90 times in trillionth of a second (as given here), and other topological statements.
19 de dez. de 2016 · There are two explanations for the quantization that do not require exotic cosmologies. The first is the large scale clustering of galaxies that traces the cosmic web. The walls and filaments formed in this web leads to groupings of galaxies around specific redshifts along the line of sight. The second explanation is the quantisation of ...

To me, this radiation is still a wave which has a microwave frequency and I also ... galaxy. universe. light. big-bang-theory. cosmic-microwave-background. Giorgi Lagidze. 315.
15 de mai. de 2023 · A model is a description of HOW. A theory is an explanation involving a human: a theory has to be understandable by experts, either in full or piece-by-piece. A model, on the contrary, needs no human; it may even be a mathematical, arbitrarily long and cumbersome description processable by a computer. Since the Big Bang contains both the WHY ...
12 de jan. de 2017 · based of this answer's to this question: big-bang-thoery-what-triggered-it-and-why they said: You may think of the pre-Planck and the Planck epoch as a state of the universe, which is dominated by quantum fluctuations. They don't need a reason or a cause to occur. They are a consequence of Heisenberg's uncertainty principle.
18 de mai. de 2014 · 4. In and of itself, no the expansion of the universe is not proof of the big bang. Other theories could be constructed that would also be explained by the expansion. For example Fred Hoyle and others proposed the Steady State Theory which proposed that new matter was constantly being created thus causing the expansion.
