How does the optical zoom works..
- Does it brings the light closer to the object... Or
- Does it just enlarges the picture of the object.
In other words... Suppose I have telescope with 1 light-year zoom capacity, could I see stars 1 year ahead of its light reaching earth...
Ps : I'm not physics graduate, but interested in physics. I joined here, to learn more... Please excuse me if my question is trivial or stupid.
