Dark matter, exotic matter- super matter, green matter DOESN'T MATTER. All these new names for matter we can't see-all scientists of today seem to keep doing is inventing some new form of matter to explain their theories, for example dark matter-the cosmoligical constant exists because there is a lot of matter we cannot see, mesure or even possilby ever create-so why do scientists stick with it? Indeed dark matter, exotic matter etc may exist, but it's obvious that if they do that they exist in some dimension we can't see, take streamsystems idea for instance, more time dimensions-could explain it and why it exists, even manipulate it, so why don't scientists think of it? Career suicide you say? Well Einstein went out on Special Relativity and thanks to his teacher Hermann Minkowski for aiding the idea to the public given HIS reputation, then that theory would have remained in obscurity and hence the geometrical representation of spacetime would not have developed either, setting us decades back in terms of development. So back to the point if the cosmological constant exists due to dark matter at such a high level, maybe scientists should look more at what existing matter can do and why the cosmological constant value is so high due to matter we have now.
PS Quantum mechanics focuses on the smallest time and energy scales, perhaps that is why it is so small, just a clue.
