\tAs light from a star spreads out and weakens, do gaps form between the photons?\tCan a fire have a shadow?Can gold be created from other elements?\tCan light bend around corners?\tCan momentum be hidden to human eyes like how kinetic energy can be hidden as heat?

Dear student 

the most accurate approach, gaps do not form between photons as light spreads out. Light is made up of tiny fundamental bits called photons. A photon is a quantum object. As such, a photon acts a little like a particle and a little like a wave, but is actually something more complex.
The answer depends on how you look at the light. However, in the most accurate approach, gaps do not form between photons as light spreads out. Light is made up of tiny fundamental bits called photons. A photon is a quantum object. As such, a photon acts a little like a particle and a little like a wave but is something more complex.
