Shaking Up the Dark Universe: The Dark Horses of Dark Matter
Δημοσιεύτηκε στις 22 Σεπ 2016
Forget
what you think you know about dark matter. After a 30-year search for a
single, as yet unidentified, species of dark matter particle that would
make up some 25% of the mass of the universe, physicists are starting
to consider novel explanations. Some envision invisible matter hiding
within the folds of extra spatial dimensions. Others suggest not one
kind of dark matter particle, but numerous species inhabiting a shadow
universe. Others still conjecture that dark matter doesn’t exist, and
instead propose that the laws of gravity need modification. We’ll bring
together leading thinkers on dark matter—the revolutionary and
conventional alike—for a distinctly unconventional discussion on the
dark universe.
