Such so-called domain walls are the natural outcome of theories that try to solve some of the deepest mysteries in physics, such as the origins of gravity. As Ferreira says, however, had they formed after the big bang, by today they\u2019d be the dominant source of energy in our universe, and there\u2019s no evidence that\u2019s the case. So any theory invoking their existence has been considered suspect\u2014until now, perhaps.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Domain walls, long a divisive topic in physics, may be ideal explanations for some bizarre cosmic quirks.
