If I put two mirrors across from each other, then put an object for them to reflect and take it away, would the mirrors continue to reflect that object from each other? Why or why not? (Better explanation inside)

Okay so if I put a mirror on a wall facing away from the wall, and I put another mirror on the opposite wall (let's say 5 feet away) facing the away from its wall, and then put an object, let's say a baseball, in the middle of those two mirrors. Each mirror would reflect that baseball, right? And depending on what angle you look at the mirror from, you'd see a reflection of the thee mirror's reflection of the baseball. So if I took the baseball away, would each mirror keep reflecting the other mirror's reflection of the baseball?

As others have mentioned, even if you had two perfectly parallel mirrors and perfectly perpendicular light, the imperfect mirrors will absorb all the light pretty quickly, but here's another wrinkle: the beam of light would fall to the Earth at 9.8 m/s^2 due to gravity!
