This conversion of energetic light into matter is a direct consequence of Einstein's famous E=mc 2 equation, which states that energy and matter (or mass) are interchangeable. Nuclear reactions in ...

Ultra-high-energy photons encircle the gold nuclei like an aura, and auras collide as nuclei zoom past one another. When photons (particles of light; massless, pure energy) collide, they generate ...

The new approach yielded what the scientists describe as the most efficient and stable source of pure white light ... longer-lasting and more energy-efficient light source than conventional ...
