It goes without saying that sound cannot travel in a vacuum. Space itself was not a complete state of vacuum, as there are still particles floating about, but in extremely scarce numbers.
It would take an unbelievably loud sound to travel across the vacuum of space. That is what seems to be happening now. A massive tremor was felt even when there was nothing to transmit said energy. But when the rift in spacetime opened, a deafening thump was heard.
"Oh shoot! We have got to go!" shrieked Jiang Fei as he rematerialized the shuttle and sped away.
Such a degree of spatial disturbance was unheard of, much less actually experienced.
A spatial disturbance of such magnitude could be described as a tear in spacetime. If spacetime itself was destroyed, all tangible matter, living or not, would follow suit, no matter how strong or powerful that something or someone was.
