small galaxies could have expunged hydrogen gas around them easily. The researchers also estimate that dwarf galaxies were abundant enough up to one billion years after the Big Bang to have ionized the entire Universe,
Because the universe has been expanding ever since the big bang. 根据题干中的关键词age galaxies和computing定位到第四段,可知宇宙自形成以来一直在扩张,因此天文学家可以通过计算星系中光线波长的延展度,来计算星系的年龄。 结果一 题目 The earliest known galaxies in the universe, which formed during the ...
) that date back to within 600 million years of the Big Bang. The six newly discovered objects suggest that the early universe may have been developing unexpectedly fast to produce these huge galaxies. While the new telescope has spotted even older galaxies, dating to within 300 million years ...
From the Big Bang to Compliance Galaxies and Black Holes Journal of Health Care ComplianceSnell, Roy J.
However, it is generally conceded now that the principal types of galaxy represent separate species rather than one species seen at different stages in its evolution. There is, in fact, no direct evidence that any other galaxy is significantly older than our own Galaxy (which is thought to be...
Reflects on the changes that have occurred in the history of the U.S. health care industry as of November 2001. Regulatory topics formed by other compliance galaxies; Topic addressed by the Compliance Institute annual meeting of the Healthcare Compliance Association; Importance of having an evolved...
Some of the faintest objects ever observed suggest that small galaxies get the credit for clearing the ‘fog’ pervading the early cosmos.
Their highly ionized gas phase has strongly sub-solar carbon and oxygen abundances, with metallicities more than a factor of two lower than that found in typical galaxies of similar mass and star formation rate at z≤2.58. These young galaxies reveal an early and short stage in the assembly ...
This paper defends Marxism's world outlook, and in detail criticizes idealism's finite spacetime,and reveals the absurdity of big bang theory, and removes the biggest obstacle for development of natural science. Besides, a new model of evolution of universe, which belongs to steady state and cor...
