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 ...
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 ...
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.
21 feb 2016 · But after the universe had cooled (it took sometime between 10 − 36 and 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 cooled enough to ...
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 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 ...
19 ott 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.
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.
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 ...
2. The most significant assumption is that very shortly after the Big Bang, the universe expanded very rapidly for a short period of time. Much faster than normal expansion due to Big Bang. It was an exponential expansion and occurred around 10−32 10 − 32 seconds after Big Bang and lasted for tiny fraction of second.
