It is unclear from the Savior's words whether this signifies the end of the entire cosmos or merely the earthly realm; hence, various assumptions can arise. Nevertheless, the Savior indicated that the conclusion of the world will usher in the Final Judgment for humanity on this earth, and if this end pertains only to those who dwell here, we may infer that it will not denote the conclusion of the universe but rather the cessation of life on this planet or the end of the earth's existence as a habitable sphere. Ultimately, this is known solely to God. However, since the words of the Lord suggest that the termination of life on earth is more likely, I feel compelled to reflect, from an earthly perspective, on the occurrences that will precede it. Therefore, I propose that the upheaval experienced by the earth will appear to its inhabitants as if stars were cascading from the heavens. It is impossible for stars to actually fall from the sky to the earth because the earth, in comparison to them both collectively and individually, is vastly small. Furthermore, the Lord instructs that when these events unfold, we should raise our heads (Luke 21:28) and witness the Son of Man arriving on the clouds of heaven with power and tremendous glory (Matthew 24:30). From these statements, we can deduce that the sky, or the entirety of creation beyond the earth and its clouds, will persist in its existence, continuing to fulfill the will of the Almighty Creator.
What will then transpire with the world we inhabit? Will the established rotation around our Sun be disrupted, causing it to be drawn in and seemingly absorbed? Or might the Sun itself cool to the point of no longer providing light and warmth? Or will there be another alteration within our solar system? All these inquiries remain unanswered, as it was unnecessary for the Apostles to solve them when discussing the signs of the world's end. Their understanding needed only to encompass that these occurrences would precede the revelation of the Kingdom of Heaven and the dawn of a new, blessed Eternal Life.
