12 nov 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 ...
23 apr 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 ...
7 gen 2016 · 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. This density caused the Universe to get extremely hot and expand.
14 apr 2021 · I understand that cosmic microwave background radiation is remnant of the universe after 380,000y of the origin. 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 mag 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 ...
19 dic 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 ...
18 mar 2017 · The Planck epoch was the earliest epoch of the Universe and lasted until 10−42 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 ×1032 K 1.417 × 10 32 K, which is the Planck temperature.
21 feb 2016 · 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 ...
The Big Bang is when the space of the universe started expanding. Near the formation of a black-hole they tell in this same article that matter and magnetic field play a key role the gamma-ray bursts. True enough. But as far as I know matter and magnetic fields played no role in the Big Bang. I know magnetic fields are induced by charge ...
15 mag 2019 · So, Big Bang happens. Space starts to expand - dramatically and to a huge extent. That's space itself expanding, not galaxies moving within space, by the way - distances themselves change. (Which is why it's called a "metric" expansion, metric being a term for distance-measures, and also why cosmologists say the Big Bang happened "everywhere").
