Before i begin, i will note that i truly don't have any idea of what i'm about to ask, but the questions elude me so ask i must. Firstly, Dark matter: finding it on earth. I've just finished watching a documentary on mapping our universe and within the program was shown a theory of trying to detect dark matter using lights under water and several swimmers, moving the lights and causing displacement. Images were consistently taken in an effort to 'map' dark matter in accordance to the distortion of the pictures. Now my thoughts on this from another angle, when two area's of different levels of heat meet, they cause a distortion of light within the air. i'm aware that dark matter travels through everything so either theory should in effect be equal, but i believe that trying my current theory would possibly deduce the amount of variables, and possibly give better results? ------------------------- Now Eternal Inflation, The idea that there are infinite universes which occasionally like bubbles if they collide leave a bruise. What about the theory of multiple universes becoming one, and expanding into one another, as appose to just colliding and leaving a bruise, they join. Your thoughts please.
