ok i wanna get this straight, people are saying that all red, blue, black, yellow diamonds are lab created and that they arent really natural

so does that mean that all people that have fancy colored diamonds means there fake?

so do they really add color in diamonds to make more money because they are fancy colored? or is this just a myth

I know that the cloud looks darker when there is a higher concentration of water vapor, but I want to know WHY more water vapor makes it darker.

I would guess from mountain water runoff and/or from aquifers, but a cite to a more substantial answer, something... Discovery Channel-worthy would be appreciated!

I'm writing a book. I'm looking for a non-poisonous natural gas that could possible be released from the ground during an earth quake. Or a non-poisonous gas that is manufactured would do as well. Thanks so much.

what proof do you have that the oceans froze over and killed all of them. when the oceans freezes over and the earth is a snowball then there is no rain this makes a perpetual snowball effect and can never be undone unless vacanos polute the earth making all air unbreathable untill it finally melt enough ice to make it rain battery acid. where is your proof on asteroids tell me !!!

there is no such thing as an ice age or we are in an ice age and it has never stoped. people believe the earth had drifted from other contininents(afica and south america) 250 million years ago, this makes sense because of it moving about the size of my finger nail growing, but if this occurred then the 250 million years worth of erosion would have halfed the sizes of the continents. dinosaur bones are found on every continent so the continents are where compacted in one piece and it was located on the equator we no this because reptiles are cold blooded and need warmth. then how long ago did the dinosaurs die and how could it be possible that man and dinosaurs co- exsisted . the dinosaurs have fossils but if this where true that the fossils are created by just laying on the ground and melting in a rock , explain to me where all the scavangers where . note asteroids are bogus and never happened on a grand scalei have mountains of proof on this as well, but only 2 charcters left

we really do need to wake up to this mystery. these traills in the sky that look like contrails that come from jet airoplanes but dont be fooled because that is not what they are. contrails dissappear within minits, chemtrails dont, they disburse and cover our sky, sometimes completly, disguising thier selves as clouds. take time to look, clouds move these things dont, they expand and just hang there right above us. SOS who is giving the orders to the jet pilots to fly and contaminate our attmosphere. ? who is the boss man ?

if the beginning of time according to evolution taught in schools is that a giant explosion (bang) happened and eventually formed into planets, where did all this matter come from? tell me, evolutionists, who or what created all this matter? how could something the size of a period on a piece of paper become all of this? if that IS true, didnt someone have to create all that matter to explode? when did something small and uncomplicated become something large and so complicated that we can barely comprehend it? if you take a stick of dynamite and put it next to some fallen trees, does it explode to become a log cabin?

does any/some of the water that comes out of the faucet come from the ocean? Or is there a way you can purify water from the ocean to make it drinkable (is there a factory where they purify it if they do, or is it more like a machine you can buy and do it yourself?)


no silly answers, thanks in advance

our text book says that there are 5 layers of atmosphere viz, troposphere, stratosphere, mesosphere, thermosphere or ionosphere and exosphere. they say that air is very rare in stratophere and they also say that ionosphere is a radio layer (remember: ionosphere is higher than the stratosphere.) sound needs air to travel and there is no air in the stratosphere. how could it reach the ionosphere and be reflected back?

Does anyone know of any journal articles dealing with historical world wide forest cover (by historical, I mean from billions of years ago to modern day). By world wide forest cover, I mean a % of land mass that is covered by vegetation. Or, data related to that.

I'm just curious. Thanks!

I understand why we would find oil in the icy places north and south because of the ice age theories and Earth rotation stuff, but why is it found so deep underground and so deep under the sea. AND, why is there so much of it found in huge pockets?
AND, just for fun...how many gallons of crude oil could you get out of a T. Rex, say?
There must have been a very HUGE amount of old dinosaurs for us to have the billions and billions of gallons of oil we have found and that we probably will find.
And what about coal? I've always heard that anything that can burn was once alive.
Help me out here. And don't call me stupid. Just curious and lazy.
