A new study published on arXiv.org shows that, based on computer simulations, Jupiter, Saturn, Uranus and Neptune may not have been the only gas giants in our solar system. According to David Nesvorny from Colorado’s Southwest Research Institute, our current solar system could never have happened without the existence of a fifth planet.
In an effort to determine just how the solar system was formed, Nesvorny performed a series of some 6,000 computer simulations. When using just the four giant planets, every simulation found that they were too large and ended up destroying each other.
After running these simulations, Nesvorny decided to add a fifth large planet into the mix. With the addition of this large planet, results found that the odds of our current solar system increased significantly. The most successful simulations show that Jupiter, Saturn, Uranus, Neptune and a fifth planet, similar to that of Neptune or Uranus, started out all tightly packed and orbiting some 15 times further from the sun then our planet Earth.
Some of the statistically best results were obtained when assuming that the solar system initially had five giant planets and one ice giant, with the mass comparable to that of Uranus and Neptune, was ejected to interstellar space by Jupiter. This possibility appears to be conceivable in view of the recent discovery of a large number free-floating planets in interstellar space, which indicates that planet ejection should be common.

Im not the OP, but my suggestion, is simple- please don't take this the wrong way, but by observing your screen name, I conclude that you are not a christian or probably don't believe in God, so making peace with Him, is probably out of the question, (everyone can change, however...I did). So the best answer I suppose, if this is true, is to make peace with yourself, your loved ones, friends, or whoever, and live everyday as if it is your last. Take time to smell the flowers. Tell someone how much you care and love them. Do something nice for someone else. If this is true, then nothing ventured, nothing gained. If it isn't true, then there won't be any negative repercussions from that. Maybe we should live everyday as if it is our last, because for some, it is. Peace to you my friend, and have a good day.

I guess you dont think with our current rate of progress in the field of science, that knowing about this could then be used to put a suitable plan into place to ensure our survival as a species.
Or worst case enable the survival of some of what we have here and maybe just maybe seeding other planets in the hope that life in the universe still exists.
I can think of no other info I would want to hear if it was the case because without knowing we would have slim to no chance.

I'll put it like this, a watermelon landing on a grape. Nibiru is supposedly ten times the size of Jupiter and supposedly a direct hit. What are we supposed to run ? There is nowhere to run.

This is a very important part of their simulations:

Don't be ignoring the fact that this possible extra planet would have been ejected from the solar system. Which means it's someone else's problem now.
