...universe right, if not help??!? I want to be a physicist but I'm not sure I fully understand inflationary cosmology. I've read some books on it, but when they talk about "quantum fluctuations" stretching out and then clumping to form galaxies and stars, I'm left wondering "quantum fluctuations of what?" I will explain my understanding of the big bang and the formation of large scale structures through inflationary cosmology, please tell me if it's right or not...and if not please tell me where I'm going wrong. Thanks.
-------The universe was once an almost infinitely small point, and the entire energy density of the universe at this time was composed of an Inflationary Energy...of which the composition is currently unknown. As the universe, at the time, was a near infinite dot, the rules of quantum mechanics applied to it. As the quantum world is very unstable and jittery, random but predictable quantum fluctuations of energy were constant in the early universe. At some points, these quantum fluctuations occured and the inflationary energy, which acts gravitationally repulsive, was more dense than in other areas. According to the predictable fluctuations, the inflationary energy would be very dense in one or more areas.
Eventually one of these very dense areas of the gravitationally repulsive inflationary energy became so dense and unstable that it released it's built up repulsive energy and burst, causing a rapid expansion. As the inflationary energy decayed (as is common with elements like Uranium and Argon) into matter, energy, and background radiation, the quantum energy density fluctuations from the beginning of the universe were stretched along with space. Eventually, as the Universe cooled, the inflationary energy decayed into matter, radiation, and energy...with these more dense areas releasing more matter and energy due to their high energy density. As the universe cooled further, particles and energy were able to interact with spacetime through regular attractive gravity, as the gravitationally repulsive inflationary energy had decayed into matter and radiation...which act in a gravitationally attractive way. This caused the more dense areas of matter and energy (released by the more dense areas of inflationary energy), which weigh more than other uniform areas of space, to clump together due to gravitational attraction and form large scale structures like planets and galaxies.--------
