List of Unsolved Problems in Physics

quantumaniac:

Wikipedia has a pretty awesome list of unsolved problems in physics, which can be read here. A couple of the interesting questions are: 

  • Is the universe heading towards a Big Freeze, a Big Rip, a Big Crunch or a Big Bounce? Is our universe part of an infinitely recurring cyclic model?
  • What is dark matter?
  • Can quantum mechanics and general relativity be realized as a fully consistent theory (perhaps as a quantum field theory)?
  • Do black holes produce thermal radiation, as expected on theoretical grounds? 
  • Does nature have more than four spacetime dimensions? If so, what is their size? Are dimensions a fundamental property of the universe or an emergent result of other physical laws? Can we experimentally “see” evidence of higher spatial dimensions?

Amazing vintage propaganda ads against the terrible menace of recorded sound, seen as a threat to musicians in the 1930s.

Wasn’t there an orchestra strike a few years back because broadway musicians were being replaced by synths?
EDIT: YUP.

Spectacular Aurorae Erupt Over Norway
Over the weekend, the Earth’s magnetic field was struck by a coronal  mass ejection (CME). The CME — a vast bubble of solar plasma that had  erupted from the sun on Jan. 19 — took longer than expected to travel  through interplanetary space, but on Sunday it made contact.

Awesome. This happened last night. :)

Thanks for putting this together, Frankie!
You have an amazing collection of Jon Stewart GIFs.

And thank you, Daily Show!!
