Scientists working at the frontier of particle physics are proposing the existence of a theoretical exotic, ultra-light “boson star” with a mass billions of times smaller than that of the electron and thinking about seeking a ‘darker’ origin of the ripples in spacetime, at the same time proving the existence of a dark-matter particle. Theories about the origin of dark matter in the universe –one of the biggest questions in science–vary from suggesting that it may be older than the Big Bang to the existence of particles the size of galaxies. Beyond the Standard Model The question of what particles make up dark matter –“dark” in the sense that it doesn’t emit radiation or hardly physically interact with anything except through its gravitational attraction –is a crucial one for modern particle physics. Observations indicate that dark matter exists, but apparently something other than the particles in the Standard Model constitutes it.
