The Elastic Ether: Why There’s No Such Thing as a True Vacuum
<p>Mathur dubs these hypothetical fuzzy bits “vecros.” They’re basically tiny quantum black holes allowed in string theory math. Like springs, vecros resist being squished. And rapidly stretching space can expand them, generating energy.</p>
<p>Cosmologists think vecros cannot grow bigger than the observable universe. So, in the early hot big bang, when light traveled faster as radiation dominated, vecros stayed compact. No stretching, no vacuum energy pumped into space.</p>
<p>But later on, when matter dominated, the universe expanded in more vecro-friendly way. Space stretched them like cosmic taffy, unveiling dark energy.</p>
