Still no signs of the Dark Matter that has to be out there in the Universe… PhysicsWeb – Dark matter remains at large

Dark Matter is matter which is detected gravitationally by not by electro-magnetic radiation (“light rays”). We know that we can only see about 1% of the total mass of the Universe. There is expected to be another 9-10% of the Universe made up of Dark Matter, with the rest of the mass of the Universe coming from “Dark Energy”. The fact that we’re not seeing what we expect to see points to a possible profound error in our present understanding of the structure of the Universe. Yea! 🙂
