Hello, the physical world would not end, the End of the World means the culture, habits, lifestyle of people everywhere independent from God will end. God did not relay the way it was intended for people to live when the earth was created. An experiment was initiated first to see how successful humans can live their own ways independent from God. So, nothing was ever said that is why God is so silent. To break that silence means to intervene in human affairs and end the separation from God. The stages of grief would surely be there in which people must choose and learn a new way of living. What passage in the Bible explains this?
Isaiah 2:2-4
Easy-to-Read Version
2 In the last days the mountain of the Lord’s Temple
will be the highest of all mountains.
It will be raised higher than the hills.
There will be a steady stream of people from all nations going there.
3 People from many places will go there and say,
“Come, let’s go up to the mountain of the Lord,
to the Temple of the God of Jacob.
Then God will teach us his way of living,
and we will follow him.”
His teaching, the Lord’s message, will begin in Jerusalem on Mount Zion
and will go out to all the world.
4 Then God will act as judge to end arguments between nations.
He will decide what is right for people from many lands.
They will stop using their weapons for war.
They will hammer their swords into plows
and use their spears to make tools for harvesting.
All fighting between nations will end.
They will never again train for war.
