Its value, about 1/137, consternates physicists because they can’t explain why it has that value, even though it is necessary for the complex chemistry that is the basis of life ( SN: 11/2/16). With an influence that permeates physics and chemistry, the fine-structure constant sets the strength of interactions between electrically charged particles. The new calculation hints that quantum spin ice could give a glimpse at physics within an alternate universe where the constant is much larger. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, physicists calculate in the Sept. A crucial number that rules the universe goes big in a strange quantum material. To include an equation typeset in LaTeX in your post, put the LaTeX code between.

New findings are always reported by multiple publications, and the fact that a specific link has not been submitted does not mean that this topic is not already being discussed on /r/Physics. Please make sure that a submission on the same topic has not been posted already. For more information on rules related to these posts, please see this thread here. This will serve to generate on-topic discussion, and separate your post from low-effort spam. If you make an image/video post, you should make a comment in the thread describing the relevant physics, linking relevant literature, any computational methods used, etc. Consider posting to /r/PhysicsJokes, /r/PhysicsGifs, or /r/ScienceImages instead. Off-topic images, videos, or otherwise "zero-content" submissions are not allowed. If in doubt, use the title of the original research.
