By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...
In case the name didn't make it clear enough, symmetry photography involves creating images that featured mirror-like scenes, ...
The line is called a line of symmetry. This is sometimes called a 'mirror line' or 'mirror symmetry', because if you put a mirror on the line, the reflection would show the whole shape.
This bold concept could address dark matter mysteries and explain cosmic symmetry gaps. In Turok’s hypothesis, right-handed neutrinos—unobserved in our universe—could exist in the mirror ...
