Shouldn't every cell in this column be the same?
- marcus_holmes 5mo agoI assumed that it was something to do with signal strength, but re-reading it, you're right, this doesn't make sense.
- cosmicSap 5mo agowhy? each star receives a different signal because the bubble has been expanding since 1900 so a star 4.2 LY away received whatever we were broadcasting in 1904, while a star 25 LY away is only now receiving our 1925 broadcasts. The column reflects what signal has actually reached each star so far, not what we're broadcasting today
