There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?
Reminder that the rules for lemmy.ca still apply!
Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice ๐.

If you had perfect mirrors set up in the perfect way, it would behave like light going through the vacuum of space without any obstructions.
Light is quantum mechanically incapable of going perfectly in a straight line; any light beam will diverge over time. This means telescopes have a maximum resolution depending on their diameter and the distance to the object. So for an infinite series you would need an infinitely wide telescope to see any detail.
Though realistically you're not getting anywhere near that because the mirrors or the air between them will absorb and scatter the light.
