Personally, I disagree with the 4.5 billion year estimate. Our methods of calculating that are inaccurate after only 6 thousand years, which I find very interesting.
But assuming a sun that has been burning for 4.5 billion years, why not? (I believe it is dense enough to have that fuel and then some)
You assume it is inaccurate because it contradicts a Flat Earth. Why might the understanding of fusion and hydrogen consumption to this process be so far off?
The sun would have to be 731,268,011 times as dense to match. That close, the gravitational field would cause serious problems!
Besides if the sun moon and Earth have different masses, than why does the UA push them all equally? The more mass with the same force would have varying accelerations.
The forces of gravity are still very unknown to scientists. It seems a likely explanation for some, but there are large problems. Like how do celestial bodies a trillion light years away know which direction to accelerate?
I feel there are many celestial forces that lie undiscovered.
I couldn't care less about your beliefs. This whole statement seems inaccurate as gravity is well understood though not
completely.
The sun's radiation, as measured in Spectroscopy, is way too high to be that close (3,000 miles) without the Earth being uninhabitable.
Why is that?
Because all known living being dies when subjected to high amounts of intense radiation of any kind let alone all the kinds emitted from the sun.
The earth is flat, the sun is not.
Tom disagrees if you read the link.
If the sun is flat, how does the energy emitted come from a nuclear reaction? Stellar fusion can't exist in a flat sun.
If it is a sphere than why does it create a spotlight effect on Earth?
The sun would have to accelerate exponentially to appear to set from one view point yet other view points on the globe would contradict this view.
As the distance of the sun gets larger, the angle of sight for the sun decreases asymptotically to zero degrees. Since the human eye is not absolutely perfect, we will be overly generous in our experiment and say that a one degree angle over this vast difference wouldn't be seen. Suppose we also generously let the suns distance reach its maximum of the diameter of the Earth continuing to favor your side. 24,900 miles long 3,000 miles high makes the angle to see the sun as 6.86999 degrees. This would make the sun seem to approach the horizon but not get close enough to mistake it for setting. Keep in mind, that this also used a distance much greater than your theory allows with timezones.
Illuminated clouds appear before sunrise.
This is the same as the horizon effect. Look at my other posts for that answer.
Perhaps post a link? The horizon effect from the sacred texts was discussed in the original thread. It better not be a useless time wasting repeat.
