If we're seeing light from stars that are not only millions and millions of miles away from our own planet but the light we say maybe hundreds of years old then I'm presuming light can travel great distances
Now what happened if you took a beam of light and two very reflective surfaces, would you not (with a strong enough light source) be able to bounce the beam back and forth between the two mirrors or whatever for sometime to come after switching the light off?.
Mirror 1 >>>> Mirror2
Mirror 2 >>>> Mirror1.
back and forth?...... if not where's the light go?
