This study is the most detailed one yet - it studied 400 red giant stars that were up to 13,000 light years away from our sun. Based on the theory of dark matter, they should have detected 0.4 to 1 kg of dark matter in that region around our sun. They found at most 70 grams. This may seem like a small amount, but it has baffled scientists, astronomers and theorists. This research does not state that dark matter does not exist, only that there is none of it in our area of the Milky Way Galaxy. This also does not explain why the Milky Way rotates faster than it should, based upon the amount of matter visible.
One interesting fall-out from this research is that this could explain why we have been unable to detect dark matter on earth - because there is simply none of it here to detect. It may mean the end of 'Dark Matter' as a theory or type of particle that explains the inexplicable, but they still have not figured out what holds or gels our universe together. Those with a spiritual viewpoint would suggest, as I do too, that Dark Matter is a spiritual energy or soul energy that cannot be described, detailed, or scrutinized with the logical mind. This brings up my own theory of why there is no Dark Matter in this part of the Milky Way. If it is spiritual or soul energy, and we have life on our planet, it could be that Dark Matter is integrated or expressed through the life on this planet, so that is why there is a lack of it in our part of the Milky Way. If there are other areas of the Universe where there is a lack of Dark Matter, could it be possible that there is life occurring in those areas, and areas with lots of Dark Matter have not manifested life as we understand it yet? I am sure there will be many logical and reasoned theories coming out about this paradox, but it is always good to give the spiritual side its view too.
