The first entities thought to emerge were quarks, a fundamental particle, and gluons, which carry the strong force that glues quarks together. As the universe cooled further, these particles formed subatomic particles called hadrons, some of which we know as protons and neutrons.In 2000, scientists looked to date what they thought was the oldest star in the universe. They made observations via the European Space Agency’s (ESA) Hipparcos satellite and estimated that HD140283 — or Methuselah as it’s commonly known — was a staggering 16 billion years old.In two separate studies, researchers led by those at the University of Copenhagen and Queen Mary University of London found that the first-ever matter created in the Universe, known as Quark-Gluon Plasma (QGP), flowed like tap water.
