丛书系列:Very Short Introductions 图书标签:VSI宇宙学Oxford物理宇宙学7天文科普物理学 Cosmology 2024 pdf epub mobi 电子书 图书描述 This book is a simple, non-technical introduction to cosmology, explaining what it is and what cosmologists do. Peter Coles discusses the history of the subject, the ...
The purpose of these lectures is to give a short introduction into a very vast field of numerical simulations for cosmological applications. I focus on major features of the simulations: the equations, main numerical techniques, effects of resolution, and methods of halo identification....
The modern consensus is, however, that a finite age for the universe is a far more important effect. Even if the universe is spatially infinite, photons from very distant galaxies simply do not have the time to travel to Earth because of the finite speed of light. There is a spherical ...
The heaven is spherical in shape, and moves as a sphere; the earth too is sensibly spherical in shape, when taken as a whole; in position it lies in the middle of the heavens very much like its center; in size and distance it has the ratio of a point to the sphere of the fixed ...
The very earliest stages of the big bang are less well understood. The conditions oftemperatureandpressurethat prevailed prior to the first microsecond require the introduction of theoretical ideas of subatomic particle physics.Subatomic particlesare usually studied in laboratories with giantaccelerators, ...
An easy-to-understand scaling of the Universe in time. The chronology of the Universe is compared to a real year. The force that moves apples and planets. A short introduction to the ideas of Kepler and Newton that culminated with the theory of Universal Gravitation....
Finally, an independent experimental evidence for νe disappearance at very short baselines exists from the Gallium radioactive source experiments GALLEX and SAGE. The existence of all these experimental hints for sterile neutrinos and a mass scale at the eV is intriguing, but so far a fully ...
IntroductionThe 07th Expansion cosmology consists of a metaphysical evolutionary journey of being/spirit, from the point where one's existence is that of a Human, to the almighty and boundless Creator, which resides beyond all restrictions. This journey is divided into two Poles/Sides, the side ...
(just as light can travel through air). At this “decoupling time,” the electromagnetic radiation was of very highenergyand very short wavelengths. With the continued expansion of space, wavelengths were stretched until they reached their currentmicrowavelengths (from about a millimetre to tens of...
