First of all, what is nothing? It could be said that nothing is the absence of presence or the presence of absence. Personally, I prefer the former to the latter since from this point of view, 'nothing' makes allowances for possibilities that the other view does not. Next, consider Heisenberg's energy-time uncertainty principle △E△t ≥ ℏ/2. If we allow for the possibility of the existence within 'nothing' of brief fluctuations over exceedingly small time intervals, the uncertainty principle suggests that the energy content of any such fluctuation would be highly indeterminate, meaning any fluctuation could contain the energy content of a whole universe or the energy of a sloth. If the time interval is long enough, it may allow the fluctuation to 'propagate' into existence and in turn time loses its point like nature and becomes a continuum. This is the moment of the Big Bang and the creation of the universe modelled here.
The universe begins chaotically, a dense, energetic soup of particles and radiation quickly expanding within the first few moments of the Big Bang. At this point, inflation takes over, smoothing out density fluctuations and allowing for the decoupling of the fundamental forces. The expansion continues, the universe begins to cool, protons can bind to electrons to form hydrogen and helium atoms, hydrogen and helium clump to form stars and from stars we get the other elements, all played out in three orthogonal dimensions and time we call spacetime.
So you see, you don't need a supercomputer or years of programming to model the universe. Boredom, beer and EveryCircuit, that's all you need.
Good day to all..
