  Do you mean if light was faster than what it is now?

  Well the speed of light is ingrained in EVERYTHING! It’s a fundemental constant, known as ‘c’. If you made it faster or slower, you’d end up changing the entire universe!
  
  The speed of light is the exchange rate between velocity and time, and between mass and energy. Everything would change. If you made light faster, the stars would burn slower, we might not be able to see them? Distances would change. Time would change. Electricity would not work the way we understand it. Colours would all be different. Everything would be different, and I’m pretty sure humans wouldn’t exist because the nerve signals our bodies use are tuned carefully to electric potentials, which would be messed with!
