宇宙的起源 英语
需要做一个课件
帮忙找一篇文章,关于宇宙的起源,“Big Bang”theory以及地球早期的形成
不用很长,大概600-1000词即可
感谢1L的朋友
但是不用这么详细
稍微范一点就好 不用太多专业术语，扯点霍金之类的
只是大致的介绍
...最好能给几个问题，就当给出的文章是英语阅读..再出几个问题（3-5个）

The Big Bang is the cosmological model of the initial conditions and subsequent development of the universe supported by the most comprehensive and accurate explanations from current scientific evidence and observation.[1][2] As used by cosmologists,the term Big Bang generally refers to the idea that the universe has expanded from a primordial hot and dense initial condition at some finite time in the past,and continues to expand to this day.
The scientist and Roman Catholic priest Georges Lemaître proposed what became known as the Big Bang theory of the origin of the Universe,although he called it his "hypothesis of the primeval atom".The framework for the model relies on Albert Einstein's general relativity and on simplifying assumptions (such as homogeneity and isotropy of space).The governing equations had been formulated by Alexander Friedmann.After Edwin Hubble discovered in 1929 that the distances to far away galaxies were generally proportional to their redshifts,as suggested by Lemaître in 1927,this observation was taken to indicate that all very distant galaxies and clusters have an apparent velocity directly away from our vantage point:the farther away,the higher the apparent velocity.[3] If the distance between galaxy clusters is increasing today,everything must have been closer together in the past.This idea has been considered in detail back in time to extreme densities and temperatures,and large particle accelerators have been built to experiment on and test such conditions,resulting in significant confirmation of the theory,but these accelerators have limited capabilities to probe into such high energy regimes.Without any evidence associated with the earliest instant of the expansion,the Big Bang theory cannot and does not provide any explanation for such an initial condition; rather,it describes and explains the general evolution of the universe since that instant.The observed abundances of the light elements throughout the cosmos closely match the calculated predictions for the formation of these elements from nuclear processes in the rapidly expanding and cooling first minutes of the universe,as logically and quantitatively detailed according to Big Bang nucleosynthesis.
Fred Hoyle is credited with coining the phrase "Big Bang" during a 1949 radio broadcast,as a derisive reference to a theory he did not subscribe to.[4] Hoyle later helped considerably in the effort to figure out the nuclear pathway for building certain heavier elements from lighter ones.After the discovery of the cosmic microwave background radiation in 1964,and especially when its spectrum (i.e.,the amount of radiation measured at each wavelength) sketched out a blackbody curve,most scientists were fairly convinced by the evidence that some Big Bang scenario must have occurred
