What happens to the unbelievers who remain after the “catching up” of the Church (the believers) at the return of the Lord Jesus Christ?

All that are left behind will die physically when the heavens are dissolved, and elements melt with fervent heat from fire falling from heaven. The spirit of the sinner returns to God that gave him the breath to live on earth. The sinner’s soul goes to hell / bottomless pit / outer darkness, a temporary place where will be weeping and gnashing of teeth. The sinner’s body returns to the dust. In a very short while, the sea, death and hell will deliver up the dead and the sinners also will rise bodily. Every sinner will be judged by Jesus according to ones works – his name would not be found in the Book of life (the person during his sojourn on earth had not received Jesus as his Life). He will be cast into the everlasting lake of fire where will continue wailing and gnashing of teeth for ever. All of these are most likely to start happening the same day.
