Hi all, after reading about flat earth I’m starting to believe this may actually be the real truth.
I strongly caution you against that. Belief got us into this mess. It won't help us to dig our way out.
Belief has no place in knowledge/fact, most especially scientific. Seek to KNOW the shape of the world instead of believe.
I was wondering if someone could explain to me how the sun stays up in the sky? Is it attached to the dome or does it have no weight therefore does not fall down to earth?
Sure, keeping in mind that no one knows the answer to this question and all we can do is speculate.
Some speculations include :
The sun is outside of "the dome".
The sun is affixed to "the dome".
The sun is inside "the dome".
The sun we see is a reflection/refraction of the real light source.
The sun is a plasma/ionization effect, the light of which is coming from our air - not a "separate body". The energy source that causes this luminescense may be invisible to us.
Personally, as I recognize that gravitation is fictional/non-real - it is more pleasing/consistent to speculate that the sun is really above our heads, and may have significant weight, but if so likely has an extremely low density. Otherwise it would violate the law of gravity (very different than gravitation, the law of gravity is millenia old).
If the sun is a tangible/material object (which it may not be, as speculated above), then it may well be "floating" above us.
