1. Dark Matter. You know that weird change in pitch as an emergency vehicle gets closer then passes you by? That weh-weh, waa -waa thing? That's the basic tool that lead to a Nobel prize in physics. It's known as the Red Shift, and led to the realisation that not only is the universe expanding at an increasing rate, it pointed out that most of the universe is invisible to every tool known to humankind.
2. Gravitational Waves. Gravy waves are remnants of cataclysms such the Big Bang, like Cosmic Background Radiation but much much stranger. Various Unifying Theories use gravy waves to sew the four forces together.
3. Can we travel faster than light? "A positron is an electron going backwards in time," said Richard Feynman. Ponder that a bit.
4. Theory of Everything. I can't rationally explain my hope that Garrett Lisi's theory of the E8 pattern gets some evidential support during the LHC experiments. Just look at it:
In the meantime, the total geek-out freak-out over the Higgs boson continues over at Public Address. We live in strange, charm, up, down times.
