What's the consensus? You guys for it? Oppose the theory?
How do you think Morgoth will break the doors? And how do you figure the other long dead minions of his will be able to return from the void?
I also wonder if any of the War of the Ring people will be sent back i.e. Olorin/Gandalf, Elessar, or elves like Celeborn, Elrond, Legolas from Valinor? And since they're bringing back Men like Turin how will they be reincarnated? They weren't in the Halls of Mandos right? So will Iluvitar himself re-embody them?
We never read anything else about the end of the world, the last battle, Dagor Dagorath.
But it´s exactly a version of Biblical Apocalyse, so the questions are the same.
How and who will return to Earth after Apocalypse. If you think in the Biblical version, good souls will come back in to a paradise, but I wonder if we can say the same with Middle Earth.
And what will happens then.
That's simply false; Tolkien's early - and late - ideas concerning the "End of the World" (called in some ephemeral writings Dagor Dagorath, or "(the) Battle of Battles") are in fact much more inspired by the ancient myths of the North, such as the Scandinavian Ragnarök.
This is shown by the fact that the "Gods" fight the War, almost excluding Man, and several heroes return to help defeat the diabolus. Also, the World is inevitably destroyed in Tolkien's myth - somewhat like in the Bible, (&c.), where the "Sinless" are removed to Paradise, but there it is also explicitly stated - although in loose terms - that the Earth would be remade by the Three Kindreds.
