Most astronomers now accept some sort of “Big Bang” as origin of today’s universe. At that time, enormous quantities of matter were created and flung投擲 violently apart across an everlarger volume of space. The time of Big Bang can be estimated in several ways. Perhaps the most direct is the backcalculation of the universe’s expansion to its apparent beginning. Other methods depend on astrophysical天體物理 models of creation of the elements or the rate of evolution of different types of stars. Most age estimates overlap in the range of 15 to 20 billion years, although a few researchers suggest an age closer to 10 billion years. Environmental Geology星際環(huán)境 The Plaary Environment2) 星球 的形成  Our Universe大爆炸理論:在重力作用下、碎片聚集、能量釋放From the debris of the Big Bang formed the stars, as locally high concentrations of mass were collected together by gravity, and some became large and dense enough that energyreleasing atomic reactions were set off deep within them. Stars are not permanent objects. They are constantly losing energy and mass as they burn their nuclear fuel. The mass of material that initially formed the star determines how rapidly the star burn。 Environment, then and now? 文明依地質(zhì)條件的應(yīng)允而存,但這種條件卻無時(shí)不刻地在潛移默化。環(huán)境地質(zhì)學(xué)學(xué)習(xí)意義 (why study it)不了解地球的學(xué)者不算一個(gè)完美的學(xué)者,環(huán)境地學(xué)知識(shí)能使其它學(xué)科,在設(shè)計(jì)施工、決策上站在 “
