An ordinary proton weighs more than the sum of its parts. Why? The new SoLID instrument, like an X-ray for the subatomic world, will peer inside and possibly find invisible particles.
🎯 Without the gluon 'glue,' the proton would be almost weightless: the three quarks inside it account for less than 2% of its actual mass.
🎬 The hunt for unknown particles echoes sci-fi ideas about hidden layers of reality, like subspace from Star Trek or extra dimensions from Interstellar.
