Einstein never made any such calculation. Even today the total size of our Universe is speculative at best. Einstein speculated it was infinite in both size and age.
he didn't
Einstein wanted to know about how the universe works.
Einstein believed in a finite but unbounded universe, where space-time is curved but does not have any boundaries or edges. This view is consistent with his general theory of relativity, which describes how gravity affects the curvature of space-time.
There are hundreds of things named after Albert Einstein. Among them are Boseâ??Einstein statistics, Einstein's constant, Einstein's radius of the universe,Einstein coefficients, and Einstein cosmological constant to get the list started.
No, in the sense that there are still things to be understood. Einstein was successful in some ways, like the Universe is four dimensional, Special Relativity Theory .
ever expanding according to albert Einstein
Einstein invented nothing. He wrote theories as to how the universe works.
The static UNIVERSE model (not a theory) holds that our Universe has been in gravitational balance for all eternity. If general relativity correctly described gravitational interaction of matter -- and Einstein DEFINITELY believed in his model -- then the Universe would have to collapse into a singularity, a fact Einstein recognized almost immediately. He thus made this collapse disappear with a wave of his hand, saying the Universe contained a force (he called it the Cosmological Constant) that perfectly balanced against a collapse by gravity. Jesuit priest George LeMaitre showed that our Universe did not need Einstein's CC if it were expanding -- an idea Einstein ridiculed. When Edwin Hubble showed that our Universe IS, indeed, expanding; Einstein admitted his CC was his "greatest blunder."
The Elegant Universe - 2003 Einstein's Dream 1-1 was released on: USA: 28 October 2003
Originally Einstein (like most scientists of the early 20th century) believed in the Steady State Universe, a theory that assumed that time had no beginning and the universe was eternal.
The first person to suggest that an expanding Universe -- one solution for Einstein's equations of general relativity -- actually described our Universe, and that we could observe certain things due to this expansion, was Jesuit priest Georges LeMaitre. Einstein not only had nothing to do with LeMaitre's efforts, he openly ridiculed the concept. Einstein later admitted that his rejection of what his formulae showed about our Universe was his greatest blunder.
Einstein didn't invent anything but he did show help us to understand to physics that govern the universe.
