Scientists will prepare graphs from processes that they are able to observe, and then extend the graph into an unknown area to attempt to predict what might happen there. This method has some use in a limited range, but it can also yield great errors because of the unpredictable nature of matter.
The text in II Peter is warning against "extending the graph" especially in thinking about the course of world events. The only reliable way to know what the days ahead hold is to find out from God. And the central theme of prophetic Scripture is the Second Coming of Jesus Christ. This is what the last book of the New Testament is concerned with. It tells of the coming revelation of Jesus Christ in His return to Earth as King of Kings and Lord of Lords. God is not held by the graphs proposed by human optimism. He reserves to Himself as Sovereign God the right to intervene in the course of human history.
God has a plan for this world. He has sent His Son to provide the gift of salvation for those who will renounce sin and receive Him as Lord and Saviour. He also warns that the apparent well being of a world that refuses this gift will not continue as some say. "For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape" (I Thessalonians 5:3).
