"The fine structure constant, and other fundamental constants, are absolutely central to our current theory of physics. If they really do vary, we'll need a better, deeper theory," Dr Michael ...

The fine-structure constant is 10 times its normal value in the material, giving a peek into what physics in an alternate universe could look like.

The Cosmological Constant Is Physics’ Most Embarrassing Problem. Physicists have new ideas about why the energy of empty space is so much weaker than it is predicted to be.
