Thanks for the answer. I've no idea how you've determined it to be so. But at least you gave an answer. Though when you say "There is definitely a dome, of this I am certain, because it makes perfect sense" you lose me. Science isn't progressed by "what makes sense". Intuition is not a reliable metric for determining reality. Intuition is subjective. We get to truth by following the evidence, wherever it may lead.
On the point of atmosphere around a round ball: The gasses that comprise the atmosphere have mass. The Earth has a gravitational field (as a result of its mass). It's gravitation that holds captive our atmosphere. It's a pretty well understood phenomenon. Gravity works in the 3 spacial dimensions we inhabit (and likely more).
Well, you were curious so I thought I'd tell you. I understand how the mainstream science world cannot be dragged screaming from their beliefs because trust in official givings are paramount to a budding learning scientists future, so why would anyone go against that.
Those who want to find the truth before they expire, will do well to open their minds to many differing possibilities to the ones that are spoon fed into their mouths and drilled into their minds by those at the top who dictate the state of play in life.
The knowledge you believe you possess is only knowledge if it's a true reflection of life, otherwise is the knowledge of fictional stories, or better still, it's the brain memory bank that holds the info that can be reeled off, as and when needed, as a potential fictional story, not a fact.
I'm a different breed, obviously, because I literally believe nothing and question everything and with good reason in my mind.
We live in a world of lies; deceit and disguised oppression, married into some truths, to keep us all plodding along.
Space science in any form is ALL lies, every last bit of it.
The Earth being a spinning ball is complete lies and all the flannel names that go with the ruse of making it work.
Our history is mostly based on lies mixed in with some truths.
