Did Something Decay, Evaporate, or Annihilate during Big Bang Nucleosynthesis?
Results of a detailed examination of the cascade nucleosynthesis resulting from the putative hadronic decay, evaporation, or annihilation of a primordial relic during the Big Bang nucleosynthesis (BBN) era are presented. It is found that injection of energetic nucleons around cosmic time 10sec may lead to an observationally favored reduction of the primordial Li/H yield by a factor 2 − 3. Moreo...
متن کاملThe Big Bang Theory
The first theoretical evidence for the Big Bang came from Alexander Friedmann in 1922, when he showed that Albert Einstein’s theory of general relativity predicted that the universe was either expanding or contracting. Einstein was so upset with this result that he introduced a cosmological constant into his theory which would make the universe static. Later he said that this was his biggest bl...
متن کاملSTRUCTURAL OPTIMIZATION USING BIG BANG-BIG CRUNCH ALGORITHM: A REVIEW
The big bang-big crunch (BB-BC) algorithm is a popular metaheuristic optimization technique proposed based on one of the theories for the evolution of the universe. The algorithm utilizes a two-phase search mechanism: big-bang phase and big-crunch phase. In the big-bang phase the concept of energy dissipation is considered to produce disorder and randomness in the candidate population while in ...
متن کاملEstimation of parameters of metal-oxide surge arrester models using Big Bang-Big Crunch and Hybrid Big Bang-Big Crunch algorithms
Metal oxide surge arrester accurate modeling and its parameter identification are very important for insulation coordination studies, arrester allocation and system reliability. Since quality and reliability of lightning performance studies can be improved with the more efficient representation of the arresters´ dynamic behavior. In this paper, Big Bang – Big Crunch and Hybrid Big Bang – Big Cr...
