The heavens declare the glory of God; and the firmament sheweth his handywork.
(Psalms 19:1) KJV
Let’s look at empirical evidence of the firmament. That means direct observation. The most recent confirmation that we have of the presence of the firmament is from the New Horizons space mission.
It confirms the findings of the Voyager missions 40 or so years ago. It’s describes as a brightly shining wall on the edge of space and it’s been reported in several places which came to our attention.
New Horizons
Here’s three examples of breathless, giddy reporting on SciPop’s failure to understand the significance of cosmic discoveries.
A NASA Spacecraft May Have Detected A Giant Wall At The Edge Of The Solar System
NASA detects glowing ‘hydrogen wall’ at edge of our solar system
New Horizons Spacecraft Sees Possible Hydrogen Wall at the End of the Solar System
What you have to remember when reading articles like these is that they were written by and for people who think that the Star Trek universe is real. As such, this is how they attempt to explain the phenomenon because it’s the only way that they can make sense of the experimental findings.
This gives us a predictive testable hypothesis: Hypothesis 3.
