Why are people still stupid enough to believe this "chemtrail" bullshit?

118. It's not water vapour. It's clouds.

Clouds are what happens when water vapour condenses into a white mist of tiny water droplets. Water vapour is entirely transparent. Clouds aren't.

Clouds expand through Brownian motion when their starting density is unusually high through having been formed at high speed from a smallish nozzle, like an aircraft jet.

Kind of like dry ice machines. You'll notice that the white misty stuff coming out of dry ice machines expands, but remains white and misty? That's water vapour condensed into a mist of tiny droplets, in a cloud, expanding to fill the available space, through Brownian motion, having been formed through a sudden drop in temperature via the release of a lot of cold carbond dioxide gas.

What do you mean "contrails dissipate"? It depends on the air temperature that the contrail finds itself in. If the air is cold, the droplets do not evaporate as there isn't enough available energy to cause such evaporation. If the air is warm, the clouds evaporate back into water vapour.

This is all very simple thermodynamics.

Didn't you think to go and check up on some simple thermodynamics before you started telling everybody about thermodynamics? Because the behaviour of vapour systems is governed by thermodynamics. And you obviously know absolutely nothing whatsoever about any of it.

I do know about it, because I've studied thermodynamics.

You may take it from me that there is absolutely nothing untoward or peculiar about the observable behaviour of the water vapour coming out of aircraft jets. You are seeing clouds, formed rapidly by the stream of water vapour particles cooling down at high speed and condensing into tiny water droplets, in conditions favourable to such behaviour. In conditions not favourable to such behaviour, i.e. warm air, it doesn't happen. Rather, the water vapour remains vapour. That's it.

There is something else that I think you should know. Even if the stuff coming out the back of aircraft jets really was some creepy chemical rather than water vapour, known physics does not describe any mechanism whereby this chemical could, in it's vapourised or atomised state, behave in any way that is dissimilar to a different cloud of something different, like, say, water vapour. Even if it were a heavier gas than water vapour (which would most likely make it visibly sink rather than float in the air) it would still have to obey the same ordinary laws of physics as every other vapourised or atomised chemical and would expand at pretty much the same rate as anything else through Brownian motion. There is no known attractive force between particles of any chemical that lend an increased "clumpiness" in comparison with other chemicals, over the scales that you would need to be proposing in order to differentiate the behaviour of your theoretical substance from, say, water vapour.

There is no chemical that ever could be "clumpier" than any other in a vapourised state. There are some that are slightly heavier, and some that "expand" slightly more slowly than others but none that have the special power of remaining clumpy in conditions where any other ordinary vapourised substance would dissipate entirely because that's not how vapours or clouds behave. That phenomenon would require a fifth force. (If you have discovered a fifth force, you need to tell some physicists. They'll be pleased.)

What do you mean they cause hazy days? How do you know the day wasn't going to be hazy anyway?

How do you explain "chemtrails" in clear blue skies, that are clearly not causing hazy days, which phenomenon I have observed quite frequently?

What are you talking about?

Why am I wasting my time on this complete nonsense?

Why are YOU wasting YOUR time on this complete nonsense?

Isn't there something important in your life? Something special and meaningful that makes you feel that your existence matters? Something beautful? Something serious? Something truthful?

Anything?
