What is light exactly?
)
November 14th, 2010
What is light exactly? I read and hear of phenomena like black holes where the gravity is so strong that even light can’t escape. Assuming that is true, why can’t it? Light is not a solid (or is it?). The only way we see what we see is because light reflects off it. Light can travel through methane, oxygen, hydrogen or any other transparent gas. Can you nail light down to a molecule? How could you capture light that none escape less you absorb it into something? It that how black holes dose, it is not so much by gravity but absorption?
