SUMMARY:Problems with the dark matter and dark energy hypotheses, and alter
 native ideas
DESCRIPTION:Problems with the dark matter and dark energy hypotheses, and a
 lternative ideas\nDr. Martin Lopez Corredoira\n\nTwo exotic elements have 
 been introduced into the standardcosmological model: non-baryonic dark mat
 ter and dark energy. The successin converting a hypothesis into a solid th
 eory depends strongly on whetherwe are able to solve the problems in expla
 ining observations with thesedark elements and whether the solutions of th
 ese problems are unique withinthe standard paradigm without recourse to al
 ternative scenarios. We havenot achieved that success yet because of numer
 ous inconsistencies, mainlyon galactic scales, the non-detection so far of
  candidate particles fordark matter, and the existence of many alternative
  hypotheses that mightsubstitute the standard picture to explain the cosmo
 logical observations. Areview of some ideas and facts is given here.(arXiv
