Physicists question model of the Universe

摘要

Cosmologists gathered in London last month to voice their concerns over the current 'standard' model of the Universe. "There is a sense of desperation," says participant Douglas Scott, from the University of British Columbia in Vancouver. "The standard model is horribly ugly, but the data support it."rnFor most in the field, that desperation stems from two unexplained ingredients in the standard model: dark matter, thought to help ordinary matter clump together to form galaxies; and dark energy, invoked to explain the observation that the expansion of the universe is accelerating.
