Thank you very much. i will consider researching the topics you have provided me, they most definitely will help. I did NEW research as in read new articles from the past week and scientists have discovered that galactic collisions can possibly reveal clues about dark matter, it may help them determine the characteristics of dark matter particles (such as wimps) wimps= 'Weakly Interacting Massive Particles'' (LOL). Other questions or titles i could consider is 'Is it possible for ''String Theory'' to explain dark matter eventually? = because most of our universe is dark, and (we only make up 0.03%, dark matter makes 23%, dark energy makes 73%, and 4% is hydrogen and helium from the stars, then most of our niverse maybe nothing but high octaves of a vibrating string. (sounds confusing i know)
Another possible title could be ''Why is most of out Universe is missing''? this is interesting, as people are referring to dark matter being the missing mass or something.
Also ''Could dark matter affect human, animal bodies/organs?
Of course some of these are questions, which could make my epq project harder wouldnt it? or am i being hard on myself? because focusing on a proved or comfirmed area of dark matter, like the one you told me about the 2011 nobel prize, could be easier. This is my problem. what type of title shall it be. In the end im doing a dissertation. Sorry for the long message, thanks for ur previous help.
