找到一篇1966年发的论文，按照狗主的回忆我感觉是前三段！大家先当做参考看，快考试了攒个rp~祝大家都能700+！！！ Over the pastdecade two subfields of science, cosmology and elementary-particle physics, havebecome married in a symbiotic relationship that has produced a number ofexciting offspring. These offspring are beginning to yield insights on thecreation of spacetime and matter at epochs as early as 10^43to 10^35 secondafter the birth of the universe in the primordial explosion known as the bigbang. Important clues to the nature of the big bang itself may even come from atheory currently under development, known as theultimate theory of everything (T.O.E.). A T.O.E. would describe all the interactionsamong the fundamental particles in a single bold stroke. The confluence ofcosmology and particle physics is even changing the way science is done. Traditionally astronomy hasbeen an observational rather than an experimental science, in which passiveobservations were made with telescopes and actively controlled experiments havebeen virtually unknown. Traditionallythe tools of particle physics have been high-energy accelerators. Nowthat cosmology has begun to make predictions about elementary-particle physics,it has become conceivable that those cosmological predictions could be checkedwith carefully controlled accelerator experiments. It has taken more than 10 yearsfor accelerators to reach the point where they can do the appropriateexperiments, but the experiments are now in fact in progress. The preliminaryresults confirm the predictions from cosmology. It appearstherefore that cosmology has become a true science in the sense that ideas notonly are developed but also are being tested in the laboratory on time scalesthat are shorter than a scientist's lifetime. This is a far cry from earlierer as in which cosmological theories proliferated and there was little way toconfirm or refute any of them other than on their aesthetic appeal. Conversely,telescopes may eventually be employed to test ideas from fundamental physics,such as proposals for a T.O.E. Indeed, tests of theories involving interactionsof particles with enormous energies could very well have only one availablelaboratory: the big bang itself.
