Physicists Nail Down the ‘Magic Number’ That Shapes the Universe
quantamagazine.org- Physicists are coming closer to nail the exact value of the fine-structure constant, alpha, which was known to be close to 1/137.
- Many famous physicists were enamored with it, saying it’s the golden ratio.
- It’s everywhere, and controls how electromagnetic forces affect charged particles like electrons and protons.
- “In our everyday world, everything is either gravity or electromagnetism. And that’s why alpha is so important”.
- The new super precise measurement puts the value of alpha at 1/137.03599920611.
