So I have a born again christian family member in their mid twenties who stated with complete confidence that there is a dome in the sky called the firmament and beyond it is where heaven is. She believes space doesn’t exist and rockets just blow up because the bible said so. She is not the brightest and normally I would let this sort of nonsense go but I work in aerospace and have multiple pieces of hardware in space so she is either calling me ignorant or a malicious agent for the devil purposely lying for her so I got pretty annoyed. I can’t find anything about this dome in a google search about religion and I suspect she ended up on a flat-earth YouTube channel that twisted a line in the bible to fit their beliefs and didn’t actually get it from her church. I know its probably hopeless to help her understand how dumb and frankly insulting this belief is but I can possibly talk some reason if I understand the source.
Are there any major or minor religions, christian or other that believe space is a lie and only god is outside our atmosphere?
It simply doesn’t describe it at all.
Also, the Bible does not even try to be a lecture on physics, or astronomy, or an engineer’s manual…
And yet we have all met Christians like OP has who try to use it to guide their understanding of the physical world.
Christians who believe the earth is six thousand years old. Who think the whole earth flooded. Who believe that women were made from men…
There are Christians who will excommunicate you if you suggest the Bible isn’t entirely and literally true.
