I don’t know if I’m making any sense, but can the second scenario be considered to be an example of infinity?
I know what you're talking about and agree with the premise on hypothetical standards. Its hard to explain things that we've never actually seen or done, but have only conceptualized. My wife emailed me a video on Youtube the other day. The topic is on quantum physics, but more specifically how our intuition can become obscured or hinder if we don't step outside of the box. It also has the potential for us to understand space-time better in order to make predictions based on current evidence.
I've been wanting to start a topic on this video, but I kept forgetting about it. Anyway, now is a good time to view it. Bear in mind that it is geared towards young teenagers. Despite that, there is still good information and the explanation is very clear and concise. The immediate topic is about time, this video is specifically about matter, but I think we'd all agree that space-time-matter are all intimately connected and all properties can act upon the other.

I wonder whether the outcome of the experiment is dependent on the status of the measuring device, i.e. does it need to be functioning for the waveform to collapse?
I was thinking that too. Would the outcome be different if we were to employ a different measuring device?
I’ve often wondered also what would happen if instead of a measuring device, different coloured filters were placed in each slit when the single photons are fired.
What outcome would you expect knowing what we now know about the quantum world? The results of the first few experiments were so counterintuitive that I'm not sure I'd place my expectations anywhere.
BTW, do you know the origin of this experiment? I'm curious to know.

Outcomes
No matter what you do, you cannot at the same time know which slit the electron went through, and still get the interference pattern. It`s just not possible.
I think we all agree with that premise but wonder why that it is. Maybe its just not possible as of yet. I mean, who would have thought that matter behaved like a wave function or that by trying to observe the phenomenon would actually cause it to behave differently than when not directly observed?

I imagine a sphere one meter in diameter, with a line extending infinitely from its surface, I will have a semi-infinite line. If I then imagine the diameter of the sphere to be halved, I still have a semi-finite line. I guess my question is, what prevents me halving the diameter of the sphere indefinitely? In other words, if I were to follow the line on its journey towards an ever-shrinking sphere, must I inevitably reach a point where the line can extend no further, and therefore be considered semi-finite?
I don't know. But I do object to the term "semi-finite." I mean, something is either finite or infinite. What in-between would exist?
