Scientists Propose New Test for Twisted Cosmic Microwave Background
Original: The Universe's Oldest Light May Be Twisted — and There's a New Way to Test It
Physicists say the universe's oldest light, the cosmic microwave background, may be twisted, and researchers have outlined a new way to test the idea. The proposal would look for patterns in the ancient radiation left over from the Big Bang that could reveal whether light was rotated as it traveled across the cosmos. If confirmed, a twist would point to new physics beyond the standard model of cosmology.
Why now: A newly proposed observational method has made the question of twisted primordial light testable, drawing attention in physics circles.
