A lot of this is way above my head, but it doesn’t really matter whether the earth is sucked in or pushed aside and possibly smashed into another planet. It is the end of earth and end of man as we know it now. Unless of course by that time man has mastered space and can transport the human race to another world.
Then again you have to ask yourself, that if this could be done, would this be the correct thing to do morally? Contaminate a virgin world with corrupt minds, war like races, felons of all denominations and sickness. Would it be Mortal survival or New World corruption, contamination and finally distruction? It might be that the unwritten law of the universe is for all life to live and perishon on the same planet.
