1. The “Dark Matter” Problem…!

5. The Laws of Physics say that Gravitational Effects
should weaken with distance from the Majority of Mass…

6. The Mystery of “Flat Rotation Curves” in Galaxies…

8. Fritz Zwicky… “Father” of Dark Matter!

12. The Larger the Scale, the Higher the Percentage of Dark Matter as
the Total Mass! The “Dark Matter Problem” gets worse & worse!

18. Serving Size: 1 Universe
Contents:
~4% : Everything in the Periodic Table, every molecule or atom,
everything that can be seen, felt, or now known to science
~96% : Invisible or Missing!

19. All Cosmic Structure was originally “seeded” by Dark Matter!
{Clusters of Galaxies…
Galaxies…
Stars…
Planets…
People…
 YOU…!}

20. Gravitational Lensing, Microlensing, & Weak Lensing
Using Observational Effects of General Relativity to Map the “Dark Matter”:
Gravitational Lensing, Microlensing, & Weak Lensing

21. Mapping the
Gravitational
Influence of
Dark Matter
“Superclusters”
with
Weak
Lensing…

31. Dark Matter Detectors are located Deep Underground…
…where only Dark Matter (and Graduate Students) are unafraid to go…

37. Dark Matter Detection Limits
(as of July 2017, arXiv: v1)
…More
Weakly-
Interacting
DM Particle
…More Massive DM Particle

38. Another Possibility: What if our
Understanding of Gravity is Incomplete?

39. If we finally do discover dark matter… guess who has the last laugh?
When researchers talk about neutron stars, dark matter, and gravitational lenses, they all start the same way: “Zwicky noticed this problem in the 1930s. Back then, nobody listened...”
