pre-flood firmament was in orbit
Greetings,
I would like to present some calculations which show that the Bible's 'pre-flood' firmament, which I believe was a 13 to 50ft layer of water, could have orbited 1720 miles above the earth. I would also like to ask for your constructive criticism --- for your review. Critics of the flood ask 'where did all the rainwater come from?'. They ridicule CRI's 'vapor canopy theory', and for good reason --- in order for the air to hold 40 days worth of rain, you would need a cloud 80 miles tall and this would have blocked out the light. Further, if the firmament were a cloud, then the situation would be no different than today. But we know it is different because now we have rainbows. There are good indications in the bible, that it did not would rain before the flood. If the firmament was just vapor, the situation would be similar to what it is today, and it would rain. The reason has to do with temperature. Today, air near the earth's surface gets heated from the sun, it expands taking with it evaporated water, it rises, where it hits cold air, which condenses out the vapor as rain. If, however, the firmament was a warm layer of water above the earth, warm air would sink, and the vapor would condense on the earth as dew. A 13ft thick layer of liquid water is a 'minimum' amount for the firmament's thickness, because if it rains only 4 inches per day (1/6 inch per hour - a lite drizzle) for 40 days/nites, you get: 4"/day * 40 day * 1ft/12inch = ~13ft I am told, that the Hebrew word used for the Noah's flood 'deluge' indicated a heavy rain; so it's likely that it rained more than 4 inches per day. 50ft thick is like a maximum thickness because using Lambert's law, 60% of the Green light (along with the rest of the visible light wavelengths) will pass though 50ft of water (See calculations in Appendix 2). Now, as Green light passes through the water into the air/space towards the earth, it is refracted and it's wavelength changes, so it becomes red. 16"/day * 40 day * 1ft/12inch = ~52ft There are satellites in a LEO (Low Earth Orbit), but these are relatively close to the earth (400 to 1200 miles above it). They are low in order to get a clearer view of the earth; however, they don't last long because atmospheric drag slows them down. 1720 miles would be out of reach of the present day atmosphere. It is possible that before the flood, the atmosphere extended right up to the water layer. We want to find out how high the firmament was orbitting in the sky: Rf = radius from the earth's surface to the firmament Now, there are 4 forces which affect the firmament's orbit around earth. 1. Fge - earth's gravity 2. Fgs - sun's gravity 3. Fae - acceleration around the earth 4. Fas - acceleration around the sun Fge + Fas = Fgs + Fae --- equation 1 The standard physics textbook 'Geostationary satellite orbit' simply equates: Fge = Fae So, substituting this into equation 1, we get: Fge + Fas = Fgs + Fge and we are left with: Fas = Fgs When this is done, the orbit is like 20,000 to 35,000 miles in space --- depending on the speed (and thus the period). However, what if, the Firmament's orbit was designed so that the Earth's gravity was way larger than the firmament's acceleration around the earth? -- that is: Fge >> Fae Well, consider equation 1: Fge + Fas = Fgs + Fae rewritting it: Fge - Fae = Fgs - Fas Since, Fge >> Fae, this reduces to: ------------------------------- Fge = Fgs - Fas --- equation 2 ------------------------------- So, let's find Fgs and Fas: ---------------- Some statistics: ---------------- Te = period of the earth's rotation = 24 hrs * 60 minutes/hr * 60 seconds/minute = 86,400 seconds Tf = period of the firmament's rotation around the earth = Te (this is an assumption, however, even if Tf is shorter or longer, Rf is not affected that much) Ts = period of sun = 365 days * 24hrs/day * 60 minutes/hr * 60 seconds/minute = 3.15 * 10^7 seconds G = Universal Gravitational constant = 6.67259 x 10 ^-11 Newtons* meter^2/Kg^2 Me = Mass of earth = 5.98 x 10^24 Kg Ms = Mass of the sun = 2.0 x 10^30 Rs = Distance from the earth (and firmament) to the sun = 1.6 X 10^9 m Re = The Radius of the earth = 3960 miles ---------------- Some Formula's: ---------------- 1. Newton's law for Fgs and Fge Fgs = G*Mf*Ms/Rs^2 Fge = G*Mf*Me/Rf^2 2. info from websites for Fas, Fas = Mf * Rs * (2 * pi / Ts)^2 ----------------- Solve for Rf using equation 2 from above ----------------- Assume for now (we'll go back and prove it later), that: Fgs >> Fas Fge = Fgs - Fas --- equation 2 G*Mf*Me/Rf^2 = G*Mf*Ms/Rs^2 - Mf * Rs * (2 * pi / Ts)^2 G*Me/Rf^2 = 6.67259 x 10^-11 * 2.0 x 10^30 /(1.6 X 10^9)^2- 1.6 X 10^9 * (2 * pi / 3.15 * 10^7)^2 MF* G*Me/Rf^2 = Mf*52 - Mf*0.0000635 Notice, that Mf*52 >> Mf*0.0000635 Notice, that Mf*52 is really Fgs, and Mf*0.0000635 is really Fas So Fgs >> Fas, equation 2 can thus be reduced from: Fge = Fgs - Fas to: Fge = Fgs and substituting in Fge and Fgs, we get: G*Mf*Me/Rf^2 = G*Mf*Ms/Rs^2 the G & 'Mf' cancel out, and we get: Me/Rf^2 = Ms/Rs^2 Rf = sqrt[Me*Rs^2/Ms] Rf = sqrt[5.98 x 10^24*(1.6 X 10^9)^2/2.0 x 10^30] Rf = sqrt[7.68 X 10^12] = 2.765x 10^6 meters Rf = 1720 miles ----------------------- Solve for Mf, Fas, Fgs, and Fge ----------------------- Now, Appendix 1 uses this value of Rf, and solves for Mf Mf = 4.14 x 10^16 (see appendix 1) Fas = Mf * Rs * (2 * pi / Ts)^2 Fas = 4.14 x 10^16 * 1.6 X 10^9 * (2 * pi / 3.15 * 10^7)^2 Fas = 2.63E+12 Notice: Fas/Mf = 2.63E+12/4.14 x 10^16 = 0.635 x 10^-4 Fgs = G*Mf*Ms/Rs^2 Fgs = 6.67259 x 10^-11 * 4.14 x 10^16 * 2.0 x 10^30 /(1.6 X 10^9)^2 Fgs = 2.16E+18 Notice: Fgs/Mf = 2.16E+18/4.14 x 10^16 = 52 Fge = G*Mf*Me/Rf^2 Fge = 6.67259 x 10^-11 * 4.14 x 10^16 * 5.98 x 10^24/(2.765 x 10^6)^2 Fge = 2.16E+18 Notice, that Fgs >> Fas Double check this --- recall: G*Mf*Ms/Rs^2 = 2.16E+18 --- equation 3 Rf = sqrt [G*Mf*Me/2.16E+18] Rf = sqrt [6.67259 x 10^-11 * 4.14 x 10^16 * 5.98 x 10^24/2.16E+18] Rf = sqrt [76.48 * 10^11] = 2.765E+6 meters = 1720 miles Toby Appendix 1 - finding the Mass of the firmament. Assuming that the firmament was 1720 miles (2.769 x 10^6 meters) from the earth's surface, and that it was 50 foot thick (15meter), let's figure out what the mass of the firmament would be. Rf+15 = radius from surface of the earth to outside part of firmament. We want to take the bigger sphere (of radius Rf + 15) and subtract the smaller sphere (of radius Rf) sphere volume = 4/3 * PI * Radius^3 Mf = mass of firmament Mf = [4/3 * PI * (Rf+15)^3 - 4/3 * PI * Rf^3] cuft * 64lb/cuft *0.45kg/lb Mf = 120 * [(Rf+15)^3 -Rf^3 ] Notice, the following Term: (Rf+15)^3 Using Binomial Expansion, we get: (Rf+15)^3 = Rf^3 + 3Rf^2*15 + 3*Rf*15^2 + 15^3 = Rf^3 + 45*Rf^2 + 675Rf + 3375 Now substitute this back into the equation: Mf = 120 * [Rf^3 + 45*Rf^2 + 675Rf+ 3375 - Rf^3 ] Mf = 120 * [45*Rf^2 + 675Rf+ 3375 ] Recall, Rf = 2.769 x 10^6 meters Mf = 120 * [45* (2.769 x 10^6)^2 + 675*(2.769 x 10^6) + 3375 ] Mf = 4.14 x 10^16 kg// |

According to the Bible, there was a whole lot more rain than just 13 feet. Consider that everything was covered, including the mountains.
If all of that water did fall, where did it go? If all of that water was in orbit (and water dissociates in orbit) how did it slow down enough to fall? Were talking delta-V's on the order of km/sec. If you're going to resort to magic and superstition to explain your universe, kjvonly, keep the science out of it. There is so much evidence that the Bible's account of creation is false that creationist scientists (there wasn't anything else back then) who went out looking for proof in the mid 1800s discounted it as false. You have been lied to. |

Welcome to Physics Forums kjvonly!
That's an amusing little set of calculations you posted, so I'm going to ask you to do some more, based on your assumptions: 1) what tidal effects would there be in the 15m water shell? 2) other than at the equator, write some equations giving the motion of the water, with specific reference to circular orbits 3) compare the mass of water in your hypothetical shell with the mass of water in the Earth's oceans, and that locked up in ice in Antartica and Greenland 4) how long after local sunset would a sphere '1720 miles above the Earth' remain sunlit? what would such a sphere look like to those on the ground, say 30 minutes after sunset on 21 March? 5) how would light from the Sun, Moon, and stars be altered by passage through a 15 m layer of water? 6) what would be the effect of a meteor hitting this water sphere? 7) by how much would this hypothetical sphere reduce the ground incidence of cosmic rays? 8) how would this sphere interact with the Earth's magnetic field and the solar wind? Specifically, how could aurora form? |

pre-flood firmament was in orbitIf this water orbited as a miniature moon, it should have been clearly visible from the Earth as a bright satellite, and there should be pleanty of historical references to this moon. But it couldn't survive there anyway since 1720 miles is well within the Roche limit. 1/6 inch of rain per hour is more than a lite drizzle. We get flooding around here when rainfall exceeds 2 inches per day. |

There is, according to some scientists, a basis for the flood theory. Specifically, before around 5500 bc (I am not sure I got the date right), the Black Sea was a small fresh water lake, with the surface below ocean level. The Bosporus was closed. At about this time, the Bosporus opened up and water from the Mediterranean rushed in flooding settlements around the lake shore. Some people miraculously escaped, and the accounts, orally transmitted for several thousand years, ended up in various flood stories.

the great flood was not so great. we now assume that the story of the great flood was derived from a story about a merchant stuck in the middle of the mediterranean sea with the animals he was to sell at market the next day. however the sea flooded a little and the merchant lost his bearings and so was lost at sea for forty days and forty nights. rhe writers of the bible saw the morales in this story and changed it to fit a more godly version including the impossible flooding of the entire earth.

Your are a mean person. The reason for my posting was to get constructive criticism. You did not address whether or not my calcuations were theoretically correct. The flood waters did not just come from rain. They also came from 'the fountains of the deep'. There is much archeological evidence, that mountains did not exist prior to the flood. For example, there is an archeological dig, in a mountain in Peru, of a pre-flood city which was actually a shipping port... The only reasonable explanation, is that the city, at one time had been much lower in elevation, but became much higher when the mountain was formed. I have read, that if all the non-water, land mass were spread out equally, around the whole earth, so that there were no mountains or valleys, the whole earth would be covered with water approiximately 1 mile deep. This shows, that there theoretically there was enough water to cover the whole earth. Toby |

I agree with you, that I should have used a radius 'R' which should have included the earth's radius. That is: Fge = G*Mf*Me/Rf^2 should have been: Fge = G*Mf*Me/(Rf-Re)^2 where: Re is the earth's radius = 3960 miles = 6.37 * 10^6 Hence, Rf - Re = 1720miles Rf = 1720 + Re = 5680miles However, it is customary to specify the 'orbit' as the distance above the earth's surface (i.e. 1720 miles)... for instance, I have an article which speaks of a LEO (Low Earth Orbit) satellite as being 500 miles above the earth, not 4460 miles from the center of the earth. In studying this topic, the articles, I looked at, were looking at orbits whose radius was way larger than the radius of the body they orbit around, hence, the radius of the body was negligible and the body was considered 'a point'. For instance, the moon is 400,000 miles from the earth, while the earth's radius is a pittance of 4000 miles. Geostationary satellites are roughly 25,000 miles in orbit which is 6 times that of the earth's radius. However, when looking at the firmament orbitting 1720 miles above the earth (of radius 4000), it cannot be said that 1720 >> 4000 Hence, the earth cannot be treated as a 'point'. I do agree that my use of Rf in the appendix (for calculating the mass of the water in the firmament) was wrong. In calculating the mass of the firmament, Mf, I should have used 1720 + Re = 5680miles = 9.14 * 10^6 But keep in mind, the '1720 miles' was calculated independent of Mf. Let's try it: I had written: Rf = 2.769 x 10^6 meters I should have used: Rf = 9.14 * 10^6 Mf = 120 * [45*Rf^2 + 675Rf+ 3375 ] Mf = 120 * [45* (9.14 x 10^6)^2 + 675*(9.14 x 10^6) + 3375 ] Mf = 45.1 x 10^16 kg It was: Mf = 4.14 x 10^16 kg BTW, this mass calculation was done for a firmament 15m thick --- which is 50ft thick, not 13ft thick. Also, it is at an orbit of 1720 miles above the surface of the earth. 50ft thick at 1720 miles would translate to something much thicker if all this mass were to be located on the surface of the earth, namely 100 ft thick as follows: 45.1 x 10^16 = ~120 * [3*T*Re^2] 45.1 x 10^16 = 120 * [3*T*(6.37 * 10^6)^2] T = 30meters = 100 ft |

I also hinted at a far more serious flaw - "other than at the equator, write some equations giving the motion of the water, with specific reference to circular orbits". From your first post |

Creationism was discounted as a viable scientific solution over 150 years ago. That's the facts of the world. If you think otherwise, you are merely believing the lies you've been brainwashed with. Your calculations are not theoretically correct. Your 'hypothesis', like every other creationist 'hypothesis', merely suspends those areas of physics which don't agree with it. Whether it's because of misunderstandings (like I'm sure yours are) or through deliberate deception (like most published creationist works), none of them fit all the data we know to exist. HINT: They aren't. Now, regarding your previous calculations: Look... I'd love to go on with this, but I think I've already proven that your calculations aren't right. They don't even make sense. It is impossible for a sphere to be hovering in orbit around a planet. The individual droplets would simply bump into each other every time they pass a node. It just wouldn't be stable. If you're considering a ring like Saturn's, it wouldn't be possible due to interactions with the Moon. This also doesn't consider the mechanism which causes the droplets to slow down ~3 km/sec so they would fall to Earth. It also doesn't consider that you can't have water in a stable state in a vacuum. It would dissociate into monatomic hydrogen (which would escape the Earth/Moon system) and monatomic oxygen (which would eventually decay and end up in the atmosphere). Like I said above (and I wasn't being mean... unless being realistic and obeying the laws of the universe is "mean"), if you want to resort to magic or superstition to explain the world, go ahaid but leave the science out of it. Science has already analyzed ALL the data, and our current best bet of what was, is, and will happen is what you read in your standard biology, geology, paleontology, physics, etc. textbooks. They all agree. Creationism is patently false. |

If I come off as harsh, Toby, I'm sorry.
It isn't you I'm angry with. It's the intellectually dishonest luddites who perpetrate the belief that creationism has any basis in fact or reality that I'm mad at. I'm furious that they pressure school districts into actually debating whether it should be taught along with actual science in science classes. I'm furious that they are destroying any chance of hundreds of thousands of kids to actually have any chance of succeeding in sciences. Unfortunately, you've already bought into it, so unseating the garbage may be difficult to do. If you actually took the time and read about the world (take a biology or geology or astronomy class), you'd see how rediculous creationism actually is. |

Also, just because most able minds can see that creationism is a load of BS does not mean that they also believe in no god. You can still believe in something greater then yourself, like many of us here.
From reading written text from a few thousand years ago can you honestly say to yourself that there is no room for error in either translation over the centuries or even just simple minded people trying to make an explanation of something they simply couldnt understand. If you showed a caveman from a few thousand years ago a lighter from today you think when he goes back to his tribe to tell others he could tell them exactly how it worked or what it even was? It would sound like magic/paranormal to those that have never seen such a thing, even to him and he was witness to it? No? Think about asteroids, meteors, comets or anything that isnt common in everyday experiences. The stories from the past are simply a way of trying to make sense of something they dont understand. Religion had its moment in the sun. Back then we didnt have science as we know it today so it was the science of the past. Unfortunately if you wanted to do real science and say anything against what religion believes to be true it was heresy and you were burned at the stake for such. Religion was just a set of rules placed with some scary stories so people could follow those rules. Look at the basic 10 commandments. What were the rules before those commandments? If we didnt live in a society without those basic 10 commandments wouldnt we be living in a terrible place? But I can tell you, we once were living like that. Someone with some great ideas seen a way to create law and order to the lands. Sick of chaos/rape/murder/thieves, dog eat dog if ya will. There was someone that laid out a good set of rules that would make a better way of life if everyone could participate. Unfortunately over the centuries religion has corrupt. It was power, (Eventually may just be the demise of mankind.) and people did everything to maintain that power. What better way to deal with a power threat then to simply call someone a witch and have them hanged, burned or stoned for whoever said the earth revolves around the sun rather then the sun around the earth. If you cant see the literally hundreds of examples of power abuse throughout the centuries because of religion im very sorry for you. Open your mind if not for but a moment to the ideas. The most terrible thing are these people that refuse to let go, becoming fanatics, blowing themselves up for their cause. They are getting smarter though, rather then blow themselves up they can send out their children to blow themselves up for them cause children are more easily brainwashed before the age of true reasoning and doubt. I myself believe in something, but I don’t believe an ounce of crap ive read in any bible. There just may be something so outrageous, so great our simple minds cant grasp or understand. That doesn’t scare me, the people that think they know everything on how and why were here are the ones that scare me. |

http://scienceworld.wolfram.com/physics/RocheLimit.html ================================= The Roche limit is the orbital distance at which a satellite with no tensile strength (a "liquid" satellite) will begin to be tidally torn apart by the body it is orbiting. A real satellite can pass well within its Roche limit before being torn apart. Consider a rigid body of mass M and radius R with a satellite with mass m and radius r orbiting at a distance d. The Roche limit is reached when a loose chunk of material. (of arbitrary mass, u ) is tidally attracted to M more than it is gravitationally attracted to m. This occurs when: Ftidal = Fbinding Plugging in, 2GMur/d^3 = Gmu/r^2 d = r * (2M/m)^(1/3) ================================= That is, if the ‘liquid’ satellite is closer than 'd', it will be torn apart, and chunks of liquid, the size of ‘u’ will be pulled toward the earth. I’m not exactly sure how we could apply this to our 15m thick, firmament situation. I guess the firmament could be considered as being composed of millions of small satellites each of radius r (= 15/2 = 7.5); in which case, the Roche limit would be as follows: The mass of each firmament sphere, Mfs, would be: Sphere Volume cubicmeter * 64lb/cuft * 1 cuft/0.0283 cubicmeter *0.45kg/lb m = [4/3 * PI * 64 * 0.45/ 0.0283] Radius^3 m = [4260] 7.5 ^3 = 1.80 x10^6 d = r(2M/m)^(1/3) d = 7.5 (2*5.98 x 10^24/1.8 x 10^6)^(1/3) = 13.9 x 10^6m = 8645miles As you pointed out earlier, this is the distance from the center of the earth. This liquid spheroid satellite is only 4685 miles (8645-3960) above the earth’s surface. In the case of the firmament, however, the firmament is NOT a speroid satellite of radius R. It's like a complete eggshell all around the earth, whose 'yolk' is the earth, and the 'white' is the atmosphere. Hence, since we are considering forces which would pull this arbitrary chunk of mass, u, apart; we must consider the other gravitational forces from the mass on each side of this so-called spheroid. That is, not only does the water in the ‘chunk’ itself attrack u; so too, the mass on each side attact it as well. In other words, the ‘m’ becomes like ‘3m’, and thus the old ‘d’ becomes d’ as follows: d’ = r(2M/3m)^(1/3) d = 7.5 (2*5.98 x 10^24/ [3*1.8 x 10^6])^(1/3) = 9.65 x 10^6m = 6000 miles 6000 miles is not too far off from the 5680 miles I had calculated as being how far the firmament was from the center of the earth, i.e. 3960 (earth’s radius) + 1720 miles (firmament above the surface) = 5680. I want to also point out, that the above Roche Limit was derived ignoring the affect of a 'third body', that is, 'the sun', Fgs upon the chunk: ‘u’. Fgs = G*u*Ms/Rs^2 Here is the new diravation: 2GMur/d^3 = Gmu/r^2 + G*u*Ms/Rs^2 2Mr/d^3 = m/r^2 + Ms/Rs^2 d^3 = 2Mr/[ m/r^2 + Ms/Rs^2 ] d = {2Mr/[ m/r^2 + Ms/Rs^2 ]}^(1/3) d = {2*5.98 x 10^24*7.5/[ 1.80 x10^6/7.5^2 + 2.0 x 10^30/1.6 X 10^9^2 ]}^(1/3) d = {9.0 x 10^25/[ 3.2 x10^4 + 7.8125 x10^11]}^(1/3) d = {9.0 x 10^25/[ 3.2 x10^4 + 7.8125 x10^11]}^(1/3) = 48160meters = 30 miles |
