Question
(3) Cosmology and Philosophy (30 points). One hundred years ago, many scientists believed that the universe was infinite and eternal, with no beginning and no end. When Einstein first developed his general theory of relativity, he found that it predicted that the universe should be either expanding or contracting, but not static. He felt so strongly in an eternal and unchanging universe that he modified his equations to eliminate evolution. When Hubble’s results became accept, Einstein called the “fix” of his equations “My Greatest Blunder!” Why do you think Einstein, as well as other scientists of his generation, assumed that the universe had no beginning? You might want to think about the nature of evidence and drawing conclusions from it. You might want to think about the role of authority. Or you might want to consider philosophical impacts…or other aspects of the issue.
NOTE: not looking for a essay, In a concise paragraph, or at most two short paragraphs (typed), give your thoughtful answer as “a nugget of knowledge!”
Explanation / Answer
All the scientists in the period of rising astronomy, believed that the universe is static i.e it neither expands nor contracts.
but with the introduction of einstein's relativity theory, he proposed that the universe is expanding, but later he himself denies this fact of expansion as he believed that one which expands or grows must have its beginning from a small particle, later he proclaimed that the universe is rather a static one.
also, in the early decades of twentieth century the scientists were not very well known about the universe, because the telescope at that time was not very powerful and they hardly detect any effective change in the universe. through this telescopes, they estimated that the universe is not expanding neither its stars. so scientists unanimously assumed that the universe is rather a static one.
therefore, with this assumption that if the universe is not expanding so, it must not have any beginning or beginner as this was also accepted by scientists at that time and Einstein himself.(which he regarded as blunder of assuming universe expansion via his relativity theory)
