An Experiment That Could Confirm the Fifth State of Matter in the Universe – And Change Physics As We Know It-reports SciTechDaily –“Dr. Melvin Vopson, a physicist, has already published findings indicating that information has mass and that all elementary particles, the universe’s smallest known building blocks, store information about themselves, similar to the way humans have DNA. Now he has designed an experiment — which if proved correct — means he will have discovered that information is the fifth form of matter, alongside solid, liquid, gas, and plasma.
