What is that, a cube of New Jerusalem?

I thought it would be a globe coming down please tell more!

I think it will take us to the NEW HEAVENS AND THE NEW EARTH,?

as you said, this earth is going to be burned totally it is so polluted with evil, it can not be undone or cleansed except eith fire

So much violence and innocent blood has been shed in it, on it, it has to be completely annihilated
