The absurd universe: Our universe just happens to be the way it is. The unique universe: There is a deep underlying unity in physics that necessitates the Universe being the way it is. A Theory of Everything will explain why the various features of the Universe must have exactly the values that have been recorded.
In the beginning, Amma dogon, alone, was in the shape of an egg: the four collar bones were fused, dividing the egg into air, earth, fire, and water, establishing also the four cardinal directions. Within this cosmic egg was the material and the structure of the universe, and the 266 signs that embraced the essence of all things.
Davies also discusses a number of other ideas connected with the "multiverse."Much like a pencil falling to the ground from its tip in a trade off of symmetry for stability, Davies writes that the Big Bang could have established a complex but stable universe (or multiverse) from symmetry breaking as the heat radiation in "space" lowered abruptly past the Curie Point.
Edward Robert Harrison's Darkness at Night: A Riddle of the Universe (1987) gives an account of the dark night sky paradox, seen as a problem in the history of science. According to Harrison, the first to conceive of anything like the paradox was Thomas Digges , who was also the first to expound the Copernican system in English and also ...
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The black hole ...
After the observation of an accelerating universe, further modifications of the model were made. [14] The Planck particle is a hypothetical black hole whose Schwarzschild radius is approximately the same as its Compton wavelength; the evaporation of such a particle has been evoked as the source of light elements in an expanding steady-state ...
Pluto's reign. For decades, students learned the phrase "My Very Educated Mother Just Served Us Nine Pizzas" to remember the order of the planets in the solar system: Mercury, Venus, Earth, Mars ...
The physical universe is widely seen to be composed of "matter" and "energy". In his 2003 article published in Scientific American magazine, Jacob Bekenstein speculatively summarized a current trend started by John Archibald Wheeler, which suggests scientists may "regard the physical world as made of information, with energy and matter as incidentals".
