Wiki - Sun

I will now look at sorting the Sun page

Original - "The sun is a rotating sphere. It has a diameter of 32 miles and is located approximately 3000 miles above the surface of the earth."

Proposed - The sun is a rotating sphere of super-heated gas (called plasma) which provides warmth and light to the earth. Through some simple mathematics (detailed below), we can show that the sun is approximately 32 miles in diameter and 3000 miles above the surface of the earth.

"The Sun's area of light is limited to an elliptic area of light upon the earth much like the light of a lighthouse is limited to a finite area around it."
I believe a lighthouse focuses light in a cone with mirrors, I am unsure how this is done with a sphere. I looked to my light-bulb for reference (not a sphere but pretty close) and it appears to light the room evenly, although a bit brighter near the ceiling. So, the sun is just illuminating the closer part of the earth more vibrantly or... is not a sphere?

"The rotating light on a lighthouse does not propagate infinitely into the distance. This means that only certain portions of the Earth are lightened at a time."
Oh, my light-bulb thing was spot-on. I was worrying I was getting the wrong end of the stick. So the light is dissipating, but how does a sphere do that so harshly?

"It also describes how night and day arise on a Flat Earth."
No, this explains why some areas are light for a cone, but the movement was not explained. A picture demonstrates this later for the lighthouse cone sphere sun(I am getting hung-up on that, sorry).

"The apparent view of rising and setting are caused by perspective, just as a flock of birds overhead will descend into the horizon as they fly into the distance."
I know smarter folks are working this through on the forums and I am pretty certain that this is not right. I don't recall the sinking ship effect being connected to the sun, which should still be 3000 miles up. I will definitely need help with that.

After that, there is a picture of how the above would work for a mono-pole placeholder for the flat earth map.
I am uncertain the current Flat Earth Society rely on this model, so I am confused as to why it is treated as a representation of the earth. Could this be substituted with the bi-polar one?

I need help with the spherical, but cone sun and some more info on sunsets/sunrises.

[/quote]Check the wiki, you may be interested on what you find/discover, or just ask a Moderator or more experienced person in the Flat Earth physics field. Directly, like Email or Messaging.

I have checked the wiki, the point is to make the wiki clearer to prevent repeated questions. I don’t like the repetition in the fora. It’s unhelpful.

As for why I put it here, I think Tom or Pete suggested putting an article here is how to help.
I don’t want to bother folks by just messaging them.

If you can help with the lightbulb problem, it would be much appreciated.

I think the lighthouse simile is the main problem, though. If the wiki could point to a similar everyday object that acts like the sun, folks would get it in a snap.

Without actually seeing the light bulb it is hard to comment about that. Are you talking about a light bulb hanging from the ceiling? I'm assuming there is no lamp shade surrounding the bulb. If it is a ceiling mounted light bulb then it will brighter on the ceiling.

You are right about the Sun being a rotating sphere of light. It does emit light evenly all over its surface area. This gives us hints about the internal structure of the Sun. There is no directed light in any particular direction such as you see from a lighthouse. The lightbulb in a light house is directed by using a combination of mirrors and lenses just as the bulb in a car headlight is in order to direct more of the light into the direction it is needed.  Directing light from the Sun into a certain direction is impossible for reasons that I can but hope I don't need to explain.

Light is a form of energy and so (as you probably know) is measured in Watts (Joules per unit time). The total wattage of the Sun is 3.84x10^26 watts and if it was only 3000 miles away as FE Wiki seems to suggest then life on Earth, indeed the Earth itself would not exist as it would have been frazzled before it could even form. It shines with an apparent or visual magnitude of -26.7 making it (obviously) the brightest object in the sky by a long shot.  If we could observe it from a distance of 10pc or 32.6 light years (the standard distance for intrinsic luminosity measurement in all stars) then it would shine at a feeble magnitude of +4.8 meaning it would be barely visible to the naked eye. By using the distance modulus (m-M = 5log10D -5) where D is the distance in parsecs (1 parsec = 3.26 light years) we can confirm its distance of 150 million km since we know it s apparent magnitude (m) and absolute magnitude (M).   

If you set D in the above equation to 10, then log10(10) = 1 so you would have (5 x 1) -5 which = 0. Therefore m must equal M.

Sorry, yes. My lightbulb is unshaded, it is also LED. It can be very bright and only seems to be a tiny bit dimmer directly above it.
I am not worrying about the necessary energy output of the sun atm, as I may look into some alternative physics for that. Sandokahn (sorry if spelled wrong) is bound to have something.
The crux of the query was to find an alternative for the lighthouse simile, as it confuses the ‘eck out of me and probly does so for others too.
