the first second of the universe

The first second of the Big Bang is theorised to include inflation instead of a more standed expansion modal. A sudden and extremely rapid expansion of the universe that occurred in a tiny fraction of a second during the universe's first second of existence Which of the following statements correctly summarizes the events in the early universe according to the Big Bang theory? The Universe was once just the radius of the Earth-to-the-Sun, which happened when the Universe was about a trillionth (10^–12) of a second old. Within the universe's first second, it was cool enough for the remaining matter to coalesce into protons and neutrons, the familiar particles that make up atoms' nuclei. Protons and neutrons then began to form. Together, these epochs encompassed less than 10 seconds of time … The cosmos contained a vast array of fundamental particles … The expansion rate of the Universe … In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius), according to NASA. The history of the Universe after its first second is now tested by high quality observations of light element abundances and temperature anisotropies of the cosmic microwave background. “By some calculations, inflation increased the size of the universe by a factor of around 10^26. Basic Elements Form The history of the Universe after its first second is now tested by high quality observations of light element abundances and temperature anisotropies of the cosmic microwave background. The history of the Universe after its first second is now tested by high quality observations of light element abundances and temperature anisotropies of the cosmic microwave background. The epoch of the first second itself has not been tested directly yet; however, it is constrained by experiments at particle and heavy ion accelerators. Kevin Harris: Bill, I don’t know if it is self-imposed or if it is used as a repellent perhaps against God … So you don’t need to have a quantum physical description of the first split second of the origin of the universe in order to predict reliably that the universe began to exist. The universe was born with the Big Bang as an unimaginably hot, dense point. As the universe continued to cool down from its inconceivably hot state, various types of subatomic particles were able to form in short periods of time known as the quark epoch, the hadron epoch, and the lepton epoch. To quote: The Physics of the Universe. The epoch of the first second itself has not been tested directly yet; however, it is constrained by experiments at particle and heavy ion accelerators. In its first second of existence, the universe was made up of fundamental particles, including quarks, electrons, photons, and neutrinos. The first second, and the birth of light. Within the first fraction of a second of the universe's existence, the four fundamental forces had separated.
