and it gets worse

The shock of the impact would have sped through the ground, resulting in an earthquake of magnitude 5.5 or higher.
All life within a radius of three to four kilometers was killed immediately. The fireball that formed would have scorched everything within a radius of ten kilometers. A shock wave moving out at 2,000 km/h leveled everything from 14 to 22 kilometers, dissipating to hurricane-force winds that persisted to a radius of 40 kilometers.

You are completely wrong about this...completely
TheLiteralist writes:
Braking DOES convert ALL kinetic energy to heat.
The point is that all of the kinetic energy has to go somewhere.
Try this experiment:
Lay an iron bar on an anvil and beat on it for a while with a hammer. What happens?
The iron bar will heat up. The anvil will heat up and the hammer will heat up. The kinetic energy from your arm swinging the hammer is converted to heat. And nothing moved.
Similarly, your idea of raindrops transferring kinetic energy to the earth and "cancelling each other out", is wrong.
Take a scenario with only two raindrops on opposite sides of the earth. Their vectors "cancel out" as you say. But they can't move the earth, since they are exerting equal forces from opposite directions. So, where does their kinetic energy go?
Heat.
Taken as a statistical population, all the raindrops of your forty-day rain will "cancel each other out" as far as movement of the earth is concerned. So, where does their kinetic energy go?
Heat.
There's no escape. All that kinetic energy has to go to heat, whether it's heating up the atmosphere by friction or heating up the earth by impact.

People who think they have all the answers usually don't understand the questions.

Vapour(isation) trails and the sound of silence
I just know I'm going to regret getting involved in this but I can't resist
I'm not by any stretch an expert on this but I think one good way to prove that the kinetic energy gets converted to heat is that the meteorite and the ground at the impact point are pretty much vapourised. This is why the ejecta from an impact can spread around the world - the iridium from Chicxulub is the most famous example.
Actually there might be another problem with the idea of all this water falling from high up in the atmosphere even if we ignore the being boiled to death part.
I imagine most people have been in a really really heavy rainstorm at some time in their life. When the rain hits the ground one of the things that happens is it makes a noise - and if it is raining hard it can become so loud you can't hear somebody stood next to you talking.
Now if I remember the sceanario being proposed we are talking about a density of raindrops falling greater than anyone living has ever experienced combined with them falling from vastly higher up than normal rain does. Isn't that going to mean that the noise is going to go up - a lot? Yet the Bible doesn't record Noah and family being deafened or walking around with blood coming out of their ears.

Re: heat = kinetic energy
Bullets aren't hot until they strike a target, for instance.
Well, not quite. There was a considerable amout of heat that pushed the bullet out of the case and through the barrel. In addition, a considerable amout of energy in the bullet gets turned to heat through friction with the air. So bullets are hot and do heat up once the cartridge is fired.
Them casings can get pretty hot too as testified by a young friend of the female persuasion who had a spent cartridge lodge in her cleavage once. IIRC she said something to the effect of "My but that does give one heartburn." Needless to say the day was a bust.

Re: collisions transfer kinetic energy btween colliding objects.
You have absolutely no idea what you are talking about.
No. SOME (not nearly all) would be CONVERTED TO (not released as) heat. The majority of the kinetic energy is TRANSFERRED to the earth, which will react. First of all, the earth will transfer SOME of the kinetic energy right back into the shuttle. And the shuttle will transfer it back again (the shuttle and debris will "bounce"...bouncing is the earth returning kinetic energy back to an object, which had transferred the kinetic energy to the earth in the first place (simply put: it fell, landed, and then bounced). The earth will also bend, break, eject, and the earth as a whole will move in the direction the shuttle was falling (but since the earth is so massive, the earth's movement will barely be noticeable).
You're nitpicking, and making false assumptions. The fact that energy is transferred around doesn't matter - all of that kinetic energy eventually is transformed into heat via friction. Everything that is set into motion by the impact eventually stops becuase of - you guessed it - friction. Splashing water doesn't in any way lessen the energy transfer.
A good example is two billiard balls. One billiard ball hits another. If the hit is dead on, almost all the kinetic energy of the first ball will be transferred to the second. The first will stop and the second will go in the direction the first had been travelling. A very, teensy-weensy bit of the energy will get converted to heat due to friction -- the force that resists motion.
Close, but not quite. ALL of the energy is converted to heat via friction. If it wasn't, the ball would continue moving and bouncing forever.
When a raindrop hits the earth, the kinetic energy is also transferred to the earth (and the earth transfers it right back). Since water drops are fluid, the water drop responds by SPLASHING (which is similar to bouncing...sort of). Very small bits of earth (grains of sand) will react to the kinetic energy of the raindrop contacting the earth. Believe it or not, each raindrop that hits the earth MOVES the earth (not by too much, mind you). But since things are hitting the earth on nearly all sides pretty much all the time, and since none of these things hitting the earth have nearly the mass of the earth...the forces fairly balance out...if it doesn't balance out perfectly, well it's such a small force that the earth is in no danger of moving out of its path. If you drop an apple on the ground...the earth moves (just a very, very little bit...it takes a lot of zeros after the decimal to describe the fractional amount of distance the earth moves in response to an apple falling or a raindrop falling...I imagine a micron would be HUGE compared to this distance.)
You seem to think that I'm talking about shifting the Earth from its orbital position. That would be bad, but that wouldn't happen here. That's not what I'm talking about. I'm talking about 31,694,485,109,760,000 metric tons of matter striking the Earth at a speed of 7 meters per second. It wouldn't move the Earth at all (the Earth itself is obviously far more massive) but every last Joule of energy would be converted into heat.
A pebble falling from the sky about the weight of a raindrop wouldn't feel much different from a raindrop. Very little energy. But if you drop a MOUNTAIN with a mass of 30,000,000,000,000,000 tons onto the Earth, it would leave more than a little crater.
Your problem is that you lack an understanding of the physics of thermodynamics, and you have trouble realizing that we are not talking about a global monsoon. You can't scale a rainstorm up to this level and expect it to feel like a rainstorm! The fact that it's water doesn't mean it will imapct with any less energy than the same mass in stone or metal.
You are welcome to use as much water as you wish...the megatons of kinetic energy do not equal an explosion of heat upon impact (raindrops do not explode upon contact with the earth...they splash). It's rain...just like all rain...the only difference is it continues for 40 days and nights, which is disasterous in other ways, of course.
It doesn't scale that way! Megatons of kinetic energy DO explode on impact! All of that energy is converted to heat, water or not!
It is friction that usually (if not always) turns SOME of an object's kinetic energy into heat...if it turns ALL the kinetic energy into heat, the object cannot continue moving. However, just because and object with kinetic energy stops moving (i.e., by collision with another object), doesn't mean that all kinetic energy turns to heat at that point, either. No, instead, the kinetic energy gets transferred to the other object. If the other object can move freely it will return very little of the kinetic energy back to the orginal object. If the object (for all practical purposes) cannot move at all, it will return all the kinetic energy back to the original object (a basket ball bouncing on the court). Friction is usually like a pest...eating up SOME of our desired kinetic energy by resisting the motion and converts the kinetic energy into heat.
You aren't carrying this far enough. Yes, one object will cause onother object to move - but that object will rub against other objects and slow through friction, just like your billiards example. The second ball moves from the impact until it has turned all of its kinetic energy into heat via friction.
The ground, were the shuttle to impact the earth, WOULD heat up. This would likely be due (I could be wrong, but I think I am right) to the shuttle trying to travel THROUGH the earth: the frictional force to this movement would be tremendous, and thus the heat would be tremendous, too (probably not like a nuclear bomb or anything, though). However, rain drop impacts do not have this problem.
Water is the same as any other material at this scale. All that matters is mass and velocity. Every Joule of that energy will be converted into heat. The amount of heat we are talking about would vaporize the Earths oceans several times over.
Go take a physics class. Please.

Re: canceling out
I get this stuff, btw, from studying physics voraciously in high school. I still really have only an introductory level. The problem here is not that this is hard to explain without diagrams to show the force vectors.
However, a simple example might do the trick.
Imagine three billiard balls in a row. The two outer ones (first and third billiard balls) are hit gently -- with the same amount of force (but in opposite directions) toward the center one. What happens? The first billiard ball transfers its kinetic energy to the center one in the direction OPPOSITE of the third billiard ball. The third billiard ball transfer its kinetic energy to the center one in the direction OPPOSITE of the first one. When the two balls collide with the center ball, the forces, being in opposite directions, cancel each other out...and the center ball will just stay right where it was (depending on how good the pool players are, of course...heh).
Forces are vectors...they have MAGNITUDE and DIRECTION. You cannot remove the DIRECTION aspect from the force...it is no longer a force if you do. Two forces of equal magnitude but with opposite directions can cancel each other out.
Now consider two men. One is standing on the north pole. The other is standing on the south pole. When the man on the north pole drops his apple, the earth will move ever so slightly southwards (the direction the apple was moving). When the man on the south pole drops his apple, the earth will move ever so slightly northward, undoing the effects of the first apple-drop.
Rain drops, especially in a world-wide flood, would be hitting the earth from all directions. The effects of a rain drop impact on one side of the earth will be canceled out by the effets of a rain drop impact on the opposite side of the earth. Overall, the net effect of the raining will be zero (if you don't include the devastation that a world-wide flood can do, of course).
No megatron bomb blasts of heat, no need to compare rain drop impacts to giant meterorite impacts, or whatever.
I reiterate that kinetic energy, during collisions, stays kinetic energy...it transfers among the involved objects (a BIT is converted to heat due to friction).
--Jason
Eventually, all of those moving objects stop due to friction. This results in heat.
And we arent talking about moving the Earth. Nobody here is that dumb. We are talking about the kinetic energy released by that much material moving at that much speed impacting the earth and being converted to heat via friction. That is ALL.

Re: canceling out
Has no one been reading my posts...kinetic energy doesn't equal heat energy and collisions do not convert kinetic energy into heat energy. Friction does that.
The water drops transfer KINETIC energy to the earth -- i.e., the rain drop impact actually MOVES the earth a teensy-weensy bit. A raindrop impact on the opposite side of the earth cancels that movement out by moving the earth back.
We've been reading your posts. You haven't been reading physics books.
You understand vectors and the transfer of kinetic energy very well. What you DON'T understand is that it is friction that stops the objects from moving. Try dropping a bowling ball from a really high place. The kinetic energy doesn't move the Earth - it STOPS, and moves the material around it, which also eventually stops due to friction. This means every bit of that energy is converted to heat in short order.
We aren't talking about two billiard balls hitting each other. We are talking about millions of gigatons of energy being released upon impact. The Earth doesn't move. Friction converts that energy into heat. If it didn't, objects (and the rain we are discussing) would continue moving forever. Obviously that doesn't happen.

Re: You are sorta right about this...sorta
the shuttle is braking all the way down. At first it is using the air resistance to do so. Once on the runway, it is using actual brakes.
Braking DOES convert ALL kinetic energy to heat. This is done because people do not wish to transfer all their kinetic energy directly to another massive object -- the earth in the case of the falling shuttle.
I feel like I'm banging my head against a brick wall.
AIR RESISTANCE IS A FORM OF FRICTION!
And in my example, I took air resistance OUT of the picture by using the terminal velocity of the raindrops - the speed at which the air resistance overcomes any additional accelleration from gravity. That's why raindrops from freaking ORBIT are only hitting at 7 m/s.
All I am talking about, all my calculations take into account, is the impact of that much material hitting the earth at that speed. It DOES release that much energy. It HAS to. You can't handwave it away by saying that the "Earth would just move a tiny amount." That's not all that happens with impacts! When a mass strikes the Earth at great speed, energy is released as heat.
You are WRONG. You need to read up on physics, specifically the laws of thermodynamics.

deformation = work
The crater is earth-deformation. Deforming the earth is work (displacing mass over a distance) -- lots of work. While deforming, the earth particles will scrub each other quite a bit, too. This will generate heat. Quite a bit of kinetic energy will be used up deforming the air (shock wave). The air particles will scrub each other more than they normally do because of this -- this will convert some of the meteor's kinetic energy to heat. Kinetic energy not used during earth deformation, air deformation, nor converted to heat will be returned to the meteorite.
Kmeteorite = Kinetic Energy of the Meteorite
Wearth deformation = Kinetic Energy of the Meteorite used up as work to deform the earth.
Hearth friction = Frictionally generated heat caused by earth particles scrubbing each other
Wair deformation = kinetic energy converted to sound waves
Hair friction = kinetic energy of sound waves converted to heat due to friction in the air
Kreturned = remaining kinetic energy returned to the meteorite
Kmeteorite = Wearth deformation + Hearth friction + Wair deformation + Hair friction + Kreturned
Of course, the meteorite, when the kinetic energy is returned to it will not bounce like a basket ball...it will shatter into small fragments (meteorite deformation, which is also work). The larger fragments will fall and replicate this same scenario on a smaller scale. Some of the fragments will be "dust" which may stay in the atmosphere for quite some time.
The point is, though, that not ALL kinetic energy is turned to heat. Most of it is converted to work (deformation and sound).
A raindrop impact deforms the earth (moves a few grains of sand), generates a sound wave (deforms the air), and generates the tiniest bit of heat in the process (but not ALL the raindrop's original kinetic energy is converted to heat). The earth returns much of the kinetic energy right back to the raindrop, which deforms very easily (we commonly call this "splashing"). Raindrop deformation is work -- as such it uses up kinetic energy. The tiniest bit of heat will be generated in the process; since water molecules slide by each other quite easily, the heat generated in raindrop deformation will not be anywhere near ALL the kinetic energy returned to the raindrop by the earth. The "splashed" raindrop is really smaller droplets that will replicate on a smaller scale the impact of the original raindrop impact (earth deformation, air deformation (sound), raindrop deformation, heat due to friction, and rebound).
The deformations use up MOST of the energy. The friction (heat) uses up the rest. This is why rebounds are never as high or powerful. Each rebound repeats the impact scenario, until all the original kinetic energy is used up in deformations and heat.
Once the earth was covered with water, the raindrops would be impacting water, which deforms quite readily (less particle resistance), thus even less raindrop kinetic energy would be converted to heat due to friction and an even greater percentage would be used in deformation -- water deformation instead of earth deformation.
Therefore, while there will be SOME (I never said NONE) of the raindrops' kinetic energy converted to heat, it is only a percentage of the kinetic energy -- and that heat energy is spead over the entire surface area of the earth and throughout the volume of the entire lower atmoshpere (sound waves) and over forty days and nights...and is water (which deforms readily) and is nothing like a meteorite impact (which occurs all at once in a concentrated location and is a solid).

let's solve your first problem
This is all very interesting but you have still failed to get the water into orbit to start with.
You need to solve that problem first.
in addition, let's say you get this water into orbit - how do you overcome the changes in pressure that would kill everything on the planet?
quote:
The appearance and disappearance of the additional amount of water (4 400 000 000 km3) required to cover the Earth's mountains, which is over three times the amount (1 370 000 000 km3) presently contained in all of the Earth's oceans, would have imposed simply impossible constraints on the pre-Flood creatures of Earth and the inhabitants of the Ark during its journey (Soroka and Nelson, 1983). If that much extra water fell as rain, the pre-Flood Earth had to have had an atmospheric pressure about 840 times higher than it has now and an atmosphere which consisted of 99.9% water vapour (which would, incidentally, have been unbreathable). Further, from a thermodynamic point of view, because 2.26 million joules must be given up as heat for each kilogram of water condensed out of the atmosphere (Soroka and Nelson, 1983), that much water vapour condensing into rain would have raised the temperature of the Earth's atmosphere in excess of 3500 DegC during the time of the Flood. The consequences for the occupants of the Ark in what would have been a boiling ocean and unbreathable atmosphere bear thinking about. Even if the extra water welled up from within the Earth, the temperature of subsurface waters of this volume, because of their closer proximity to the hot mantle of the Earth, would have resulted again in oceans boiling away at temperatures of approximately 1600 DegC. Either way, Noah's geese would have been cooked.

raindrops from orbit

Yup. I have stated this repeatedly. And friction is a vector force in a direction opposite the object's motion...and causes heat. (I have never said that NONE of the raindrops' kinetic energy would be converted to heat. What I have repeatedly said is that NOT NEARLY ALL the raindrops' kinetic energy would be converted to heat.
rahvin writes:

Well, I am not proposing that the rain drops fall from orbit. I have already stated earlier that "orbit" was a poor choice of word on my part (I need the raindrops to go high enough to transfer geothermal energy to space...however high that is...if that's orbit...that's orbit, but it might not be).
This would be just above whichever layer of the atmosphere traps energy, wouldn't it?
However, whether the water droplets go to orbit or not, is not the main thing concerning from how high the raindrops fall. Raindrops don't even exist until they condense into raindrops. I have no reason to believe (right now) that the water that went so high condensed into raindrops at that height. I, so far, imagine the raindrops condensing right where they do today...a few thousand feet up.

When a mass strikes the Earth at great speed, energy is released as heat.
First of all, I am not handwaving. Whenever I realize I am wrong, I try to own up to it...if I feel my admission really affects the discussion. What I am doing is digesting the critiscisms of my idea and trying to defend my position as I best can. I am not always correct.
After having studied on the internet some more about the apple-moving-the-earth (a common physics discussion...but I took physics about 15 years ago), I am a bit wrong about "moving the earth." The physics discussions were about the apple's gravity pullin the earth toward the apple an imperceptible distance (but it does move the earth...so would a raindrop). Does this mean that the apple's impact would also move the earth? I am no longer as sure as I once was.
However, it matters not. Deformations DO use up kinetic energy. Heat is produced during a deformation, but only a small percentage (depends, I imagine on the materials being deformed) of the energy used to deform is converted to heat.
You keep using the term "released as heat"...I'm not sure that is appropriate (it might be, but I am not sure). I prefer to say the energy is "transferred", "used up", or "converted"...how appropriate those terms are...I am not sure, either.
In either case, I do not feel anyone has proven that ALL the raindrops' kinetic energy is converted to heat. Although, Crash is coming pretty close to convincing me.
rahvin writes:

If you mean the idea that energy cannot be created nor destroyed, I am trying to keep that in mind.
I might be wrong (despite all the confidence I have or had). I have only briefly studied up on deformations...it could be that ultimately all deformations cause all kinetic energy to convert to heat.
I do, however, feel certain that your calculation is oversimplified. For one thing, you are treating it like a single event. It is not. It is gazillions of impacts over the entire surface of the earth over forty days and forty nights. The heat energy, whether it be all or only a small percentage of the kinetic energy would be distributed throughout all the surface of the earth, much of the volume of the lower atmosphere, and, after awhile, throughout the flood waters themselves.
If my "model" is correct, how does the geothermal energy released compare to the heat generated by the rainfall? I say this, because the earth would probably have a net loss of "heat" and would be one giant heat sink, wouldn't it?
How does the energy transfers during condensation of raindrops affect your calculations, if at all?
Water evaporates. The flood waters would experience evaporation, too, throughout the 40 days and nights and beyond. Doesn't this cause a reduction in heat? How much? How does this affect your calculations, if at all?
Finally, Charles Knight has offered up a "problem" that might become a (at least a partial) solution -- namely, the "nuclear winter" the intial "fountains of the deep" might cause.

Re: Vapour(isation) trails and the sound of silence
That is interesting.
One thing is this is where some of the kinetic energy is being put...soundwaves (does it eventually all turn to heat? Maybe it does...because soundwaves do eventually stop).
As far as the ever increasing sound level is concerned, I would tend to think that the sound waves from one raindrop impact would be cancelled out by another. Not all would cancel out, though. IOW, I think there would be a limit to how noisy it could get.

Now if I remember the sceanario being proposed we are talking about a density of raindrops falling greater than anyone living has ever experienced combined with them falling from vastly higher up than normal rain does.
I am not, and neither do any other YECs that I know of, proposing that all or even nearly all the Flood waters came in the form of rain, but rather from the fountains of the deep (the initial blasts of which, may have provided most or all of the rain).
And, to be clear, I am not proposing that the raindrops fell from orbit, but rather that the water may have went that high. I am, so far, saying that the water vapor and atomized water particles condensed into droplets just where they do today...a few thousand feet up.

Not half as much as my arthritic hands regret me getting involved in this. :^)

I need the raindrops to go high enough to transfer geothermal energy to space...however high that is...if that's orbit...that's orbit, but it might not be
That's orbit which is a minimum of 62 miles up - requiring the water to travel at 18,000mph to get there - requiring you to suggest a sensible mechanism that prevents it turning to steam.

deformation

The point is that all of the kinetic energy has to go somewhere.
Try this experiment:
Lay an iron bar on an anvil and beat on it for a while with a hammer. What happens?
The iron bar will heat up. The anvil will heat up and the hammer will heat up. The kinetic energy from your arm swinging the hammer is converted to heat. And nothing moved.
Well, actually, the anvil, the bar and the hammer will all deform. The deformation will cause the atoms and molecules to scrub each other and generate heat.
My question then becomes does all the kinetic energy become heat given that there is deformation?
You guys have just about convinced me that it does, but not quite yet.

Finally, Charles Knight has offered up a "problem" that might become a (at least a partial) solution -- namely, the "nuclear winter" the intial "fountains of the deep" might cause.
Not really because you cannot actually get the water into a place where such an event would occur and THEN you need to explain how you overcome the pressure problem.
Then I've got about 6 or 7 other problems relating to basic "impossible to handwave away" physics to put to you.
Why you are getting worked up about the complex stuff when you can't answer the most basic questions is beyond me.
