Parity Symmetry Violation in Orientation of Galactic Shapes Could Explain Abundance of Matter

May 23, 2023 by News Staff

Symmetry is a tidy and attractive idea that falls apart in our untidy Universe. Indeed, since the 1960s, some kind of broken symmetry has been required...

As the CMB light (left image) travels through the Universe until observed on Earth (right image), the direction in which the electromagnetic wave oscillates (orange line) is rotated by the angle β; the rotation could be caused by dark matter or dark energy interacting with the CMB light, which changes the patterns of polarization (black lines inside the images); the red and blue regions in the images show hot and cold regions of the CMB, respectively.
