they are things we don't understand
dark energy ~ 70%+/-..
dark matter ~ 30%+/-..
the rest ~ 5%
As you can read from the name,like standard model, matter means fermions
while energy corresponds to scalar or Casimir energy. here is the same.
so darkenergy candidate is vacuum energy or some scalar.
This dark matter also has different terms
hot darkmatter, like neutrinos which the mass is about .5ev but couple
with regular standard model thing at order 1( |
