Not enough 'why' questions being asked here.
- UP points at Merope 5c - Why?
- UP responds to the discovery scanner with a burst of audio in which a diagram (or 3, or potentially more if we've missed them, depending on how you look at it) can be found encoded as DbFreq plotted against time. Why?
- Inside the image, we have a circular figure, reminiscient of a sphere, with a radial line roughly at south east east, and an arc segment on the circumference marked by two outer lines. Why?
- Around the circular figure, we have four symbols in the corners - '-|-', '-||', '|--', '--|' reading left-right, top-bottom. On the top right symbol, we also have two quarter-arcs that either accompany that symbol, or which accompany the circle & just happen to be really close to that symbol. Why?
- To the right of the circle, we have what appears to be a stretched version of parts of the circle: the top-right and bottom-left quadrants, although bits are missing (no gridlines in particular). Why?
- On the right, also, there appears to be a part with the letters 'VV'. Why?
- On the left, there is a shape that looks like an angled 'C', above a fuzzy shaded box, and preceded by a '.' - Why?
- There are some other arc details and '.' characters on the left also. Difficult to make out, but they are there. Why?
I'm sure there's more, but you get my point.
Everyone is rushing to answer the question 'what?' - but very little success is being made because we don't know which 'what' we need to answer.
Before we do that - we need proposed answers for 'why?' - this will provide context for analysing the detail to give us a 'what?', and then we can get to 'how?'.
So an example:
Why embed an image in the sound?
To broadcast information that can only be conveyed by image
What information?
A location of interest to the probe.
Why broadcast it to us?
Because they want us to find it
How do we get a location from the image?
By understanding how to decode the information in the image of course!
What information could be encoded in the image?
Galactic and/or system location. Planetary surface location, perhaps.
Okay, how?
I dunno!
Anyway - keep the questions simple, use the observations to inform the questions, come up with a simple explanation for part kf the image, and try to use that to interpret the rest.
If you get it wrong, it won't work and you can go back to the previous question.
We need to be more ordered. We also need more UPs. They might still provide more data to be observed - and we can't get that if we don't have UPs.
