Title: Gravity Problem-Solved?
Post by: MrQweep on December 19, 2014, 02:06:54 PM
Alright, so the flat earth theory runs into some problems when it comes to gravity:
1. Gravity decreases as height increases. If the earth were accelerating in a linear path, this wouldn't happen.
2.If Earth accelerated at 9.81m/s², it reach the speed of light within one year. This hasn't happened(and don't tell me about weird space-time warping and stuff)
would
To solve this, we have to forget the idea of the earth accelerating in a straight path and instead think of it going in a circle, with the surface towards the center. This way, a constant acceleration can occur without the earth actually speeding up.
Also, if the radius decreases(e.g. you climb a mountain) with the angular speed stays the same, acceleration decreases as well. We can also observe this on our earth.

To calculate the angular speed as well as the radius of the circle we are moving in, we can use some of the observed data: from sea level to 9000 gravity decreases by 0.29%. Now, with the formula a=ω²r we can create the equation:
ω²(r-9000)=(ω²r)-(0.0029*g)
If g is the standard gravity of 9.80665m/s², we can solve this for ω and we get the result:
ω≈0.0017762s⁻¹
If we use this in the equation a/ω²=r we can conclude that:
r≈3126859m=3126.859km

This post shows how when you solve some problems of a weird theory, others pop into existence...

Thank you for reading this and have a good day

Wouldn't this necessitate the earth being a bowl shape to maintain equal force across it?

Rather a circle laid along a cylinder as it is actually moving around a line, but yes. Before calculating this, I assumed the radius would be much bigger than 3000km, thus making the curvature very slight and excusable by the fact that gravity is observably weaker on the north pole, but it turned out to be very small and not realistic(as if any of this was ;)).
Indeed it is kind of a failed theory :( But it was the first thing that came across my mind when thinking about a flat earth and I just felt like sharing it...

To be clear I am a round earther here to hone debate skills, but its refreshing to have someone here actually trying to figure out how to fix the problems with FET instead of ignoring them!

I am too, of course, but I view this more like a physics/logic puzzle with many people collaborating to find a solution on how to make a flat earth work without discarding all observations as a conspiracy.

But let's not get too off topic here, we have a problem at hand which is: the radius is too small to be unnoticeable. Any physicist or mathematican got a way to increase the radius while letting the ratio of gravity on different heights be intact?

Sounds like something Alpha could probably do. Though I don't know if he would want to give FErs an ironclad theory. :P

Actually I quite like this model for its simplicity. It can also explain the variation of gravity observed in real life. Ironically, this idea has to come from a round earther.

That's a clever approach. I wish I'd thought of it.

Heck, if I could find an ironclad theory in favor for how a flat earth worked I'd believe it myself. And maybe win the friggin Nobel Prize!

Your signature is still flawed because Hitler actually believed in the concave Earth hypothesis and the current pope believes that the Earth is round.

I just want to touch on one statement here...

Quote
a constant acceleration can occur without the earth actually speeding up.

Do you understand what acceleration is? I think you meant centrifugal force.
That would require that the Earth, ironically enough would have to be round. (In the opposite way as RET, but..)
And let's not even get started on the fact that if that were the case we should be able to see the other side of the world by simply looking up.

Jroa derails another otherwise insightful and creative thread....

I think it's pretty cool that RE folks seem to come up with the math to make FE theories more concrete, only to be thrashed and dismissed.

Reminds me when I postulated a possible motivation behind the Great Conspiracy that many REs could buy in to, only to be met with "nope it's financial."

The reason is because Earth's gravity pulls at 9.8 m/s2 and light goes 800,000,000 m/s, soms basic trigonometry would reveal that light does drop, but by an absolutely tiny amount.

300,000,000* lights a constant though, gravity should effect it regardless of speed, by that logic it would always be dark because light would whizz past us and away from us, look at a candle, the fire is pointing upwards, not being dragged down...

That's like saying that a bullet should drop to the ground imediately after it leaves the gun's barel because it's effected by gravity.  A bullet fired falls just as fast as a bullet dropped, however the fired bullet has already gone s long distance before it hits the ground.  In the time that it takes an object to fall a few feet from rest light can travel around Earth (assuming it's round) many times.  Basic trigenometry will tell you exactly how much the light will drop as it travels, try it.

Candle flames are not made of light, they are made of burning gasses that are so hot they emit light.  The reason that it rises is because the gas is low density due to the heat and it cools off and stops glowing shortly after being released.  The light emitted from the flame hits your eye making you see the glowing flame.  The flame is not made of light.

Speed of light in a vacuum, Cvac = 299,792,458 meters per second and in air it is ~ 299,700,000 meters per second.  That  is pretty fast, wouldn't you say?.  Now consider that a particle moving at this speed hitting your eye, if photons had any considerable mass they would obliterate your eye.  Fortunately the mass of a photon is very small, in fact its rest mass is zero.  So we can safely say the mass of a photo is very small, thank goodness for our eyes sake.  This means that the gravitational force between a photon and the earth is very small, in fact nearly zero.  So small that it is damn hard to detect:
F = (G * m1 * m2) / r^2
if m1 is the mass of the earth and m2 is the mass of the photon, m2 -> 0 means F -> 0.

The light in a candle is the result of gases in combustion.  Photons are emitted from the bright areas, some of them in the direction of the viewer.  The shape of candle flame has nothing to do with the direction photons are moving.  Look at a tungsten bulb under low power (use a dimmer switch so you don't hurt your eyes), you will see light emitted from the length of the filament.

Imagine you drop an object and measure how far it has fallen 0.001 seconds later, that's how far a beam of light will fall in the trip between a lightbulb in your house and your eye.  That's not very significant.  As for the flame having mass, a candle gets shorter as it burns, where do you think that mass goes?

If gravity can pull in light (black hole) why doesn't it fall from the roof to the ground?

The reason is because Earth's gravity pulls at 9.8 m/s2 and light goes 800,000,000 m/s, soms basic trigonometry would reveal that light does drop, but by an absolutely tiny amount.

300,000,000* lights a constant though, gravity should effect it regardless of speed, by that logic it would always be dark because light would whizz past us and away from us, look at a candle, the fire is pointing upwards, not being dragged down...

That's like saying that a bullet should drop to the ground imediately after it leaves the gun's barel because it's effected by gravity.  A bullet fired falls just as fast as a bullet dropped, however the fired bullet has already gone s long distance before it hits the ground.  In the time that it takes an object to fall a few feet from rest light can travel around Earth (assuming it's round) many times.  Basic trigenometry will tell you exactly how much the light will drop as it travels, try it.

Candle flames are not made of light, they are made of burning gasses that are so hot they emit light.  The reason that it rises is because the gas is low density due to the heat and it cools off and stops glowing shortly after being released.  The light emitted from the flame hits your eye making you see the glowing flame.  The flame is not made of light.

A bullet will still hit the ground. The flame still has a mass?

Imagine you drop an object and measure how far it has fallen 0.001 seconds later, that's how far a beam of light will fall in the trip between a lightbulb in your house and your eye.  That's not very significant.  As for the flame having mass, a candle gets shorter as it burns, where do you think that mass goes?

Try .00000001 seconds (over 10 feet).

Light would fall about .0000000055 inches over an entire mile.
