I believe it's prophetic language, "figuratively speaking". Metaphor. The same was said in the prophecy regarding the coming judgment of Babylon 2,500 years ago:Ponder this = "Then the sky receded as a scroll when it is rolled up, and every mountain and island was moved out of its place."
And all the host of the heavens shall be dissolved, and the heavens shall be rolled like a scroll; and all their host shall droop, as a leaf falls off from the vine, and as the falling from the fig tree.
For it is the day of the LORD's vengeance, the year to repay for the fighting against Zion. And its streams shall be turned into pitch, and its dust to brimstone, and its land shall become burning pitch. It shall not be put out night or day; its smoke shall go up forever. From generation to generation it shall lie waste; none passes through it forever and forever.
There is a lot of metaphor and hyperbole in prophetic language. It's common in the ancient world.
