Earth at Night
Cosmic Pie
Structure formation
Neptune vs. Ether
Stuff we don’t
see
Need to change the
theory
Neptune discovered
(1846) as gravitational
perturbation to Uranus.
The Michelson-Morley
experiment (1887).
Bullet Cluster
Source of Dark Matter
Potential Candidates for Dark Matter
Astrophysical Tests of
Particle Physics Theories
New “dark” forces would predict
clouds of DM to be distorted as
they pass through each other
Decay of WIMPs to superWIMPs may produce photons or
electrons which can break light
nuclei
Astrophysical Tests of
Particle Physics Theories
New force in dark sector (with Sommerfeld enhancement)
predicted to produce enhanced leptonic annihilations in
substructure in the halo (PAMELA, ATIC)
So far no-show
But we’re getting closer!
