					<description><![CDATA[<p>“Why is there a speed limit?” can mean two slightly different things: Why is there any maximum speed at all—why isn’t information allowed to propagate arbitrarily fast? Why is the limit the particular value we call c—about 3 x 108 &#8230; <a class="kt-excerpt-readmore" href="https://www.telework.ro/en/do-we-know-why-there-is-a-speed-limit-in-our-universe/" aria-label="Do we know why there is a speed limit in our universe?">Read More</a></p>
