| iMo:
The existence of our Universe and life on Earth is just a coincidence. |
| SilverSolder:
Is this about the right time to bring up Baudrillard simulacra? |
| DG41WV:
Just do whatever your monkey brain tells you to do and try not to dig too deep. Ignorance is bliss. |
| unknownparticle:
Totally. There is sure to be an extinction level event just around the corner. |

Question asked to the teacher, how did the universe as we know it form. In the early days of the universe it was incredibly hot, so much so that energies and temperatures were far in excess of the best we can achieve these days, even with the largest particle accelerators, with the highest energies we can safely contain. The original universe was a single point, which rapidly expanded, and slowly cooled down. Eventually it cooled down to the point where electrons could combine with protons to form neutral hydrogen, and the photons thus could travel in long paths without colliding. We can still see the remnants of this in the background radiation, though it is approaching absolute zero. Then the first suns formed, hot and bright, and they formed all sorts of exotic matter when they eventually went supernova, forming the first black holes. As the universe expanded, the time it took for light to travel from the furtherest points got longer than the time since the universe began, and some of the oldest objects were lost forever from view. Thus we cannot see the furtherest galaxies, though we know from empirical evidence and deduction that they must be there, as there are echoes of the mass imprinted on the background. Eventually the longest living brown dwarf suns also burnt out, forming the cool iron cores, which currently are circling the black holes illuminating the universe from Hawking radiation, giving us the energy we need to survive. There are occasional mergers of these black holes, but they are luckily not common, the radiation is deadly for large distances, energies approaching the early days of the universe, around 14 billion years after it was formed, out of a singularity quantum fluctuation. The odd iron core will fall in, but those events can be predicted long in advance, and we move far enough away so that we are not destroyed from the deadly heat. It is hard to imagine a universe where there is so much energy that material is not all a nice comfortable solid, with the exception of the life giving supercold helium we need to survive. imagine where things that we consider immutable, like hydrogen, carbon, iron and nickel, are hot enough that they actually flow, and can form gases that are incredibly corrosive to us, and where chemical reactions occur almost at the speed of light. However, this is only the introduction, and the full course material will be the occupation of those students who chose this course, and who complete the study period and pass. Class will occur at the beginning of the semester for those who qualify. |
