Air Pressure vs Gravity

Quote from: markjo on January 20, 2017, 06:22:08 AM

Gravity pulls the wood down into the water.  The rigidity and nonporosity of the wood are what push the water out of the way.

How does gravity pull the wood down.

Nobody is 100% sure, but there are several theories as to how gravity works.  Some think that mass warps space-time in such a way that it creates a lower energy potential and others think that it's due to force mediating particles within atoms.  However, what we do know for sure is that the gravitational influence between objects is proportional to the mass of the objects and inversely proportional to the distance between the objects.

The water is there and the wood is on the water.
The moon supposedly pulls the water up with its gravity but gravity pulls the wood down into the water?
Seriously?
Frigging seriously?

What does the moon have to do with it?  For the sake of small scale displacement experiments like the ones that we're discussing here, any celestial gravitational influences can be safely ignored.

And people call my theory nonsense even though I can actually explain it with genuine real sense.
Hilarious.

We call your "theory" nonsense for lots of reasons, not the least of which being that you claim to explain reality, but demand unrealistic conditions for your "experiments".  Crushing the air out of a steel block?

Gravity is trying to pull the wooden block down. When the block contacts the water it is still being pulled by gravity but now the pressure of water is trying to push it up.

Ok, so we have the water pushing the block up and gravity is pulling it down.
So can you tell me how gravity is pulling the wooden block down.
What's grabbing it under the water to pull it down and how does the water push it up.
Mainly I'd like to know what the gravity force is that's pulling on the wooden block.

Mass attracts mass. This is gravity.

The earth and the wooden block are pulled towards each other.

A grain of sand does not jump up and stick to a mountain.
Mass attracts mass as an explanation for fictional gravity. What a heap of crap.
Mass attracts mass because atmospheric pressure sees to it that it happens, otherwise the world would not exist for us.

Nobody would expect a grain of sand to jump and stick to a mountain. A cursory calculation of the force involved using the law of gravitation show this. So before you moan about a theory, learn about it first.

F = GMm/d^2

F = Force
G = gravitational constant
M = mass object 1
m = mass object 2
d = distance between M and m

The force between the grain of sand and then mountain would be incredibly small.

These don't understand just how weak gravity is compared to the other three forces. It takes the whole earth to pull down a paperclip but an ordinary magnet can pick it up. Or you can pick it up with one finger.

Which brings up an interesting point. Scepti, how does denpressure explain magnetism? Could you answer this with clear, simple terms?

Haven't you heard? It's all a clever dupe. Just think about it.

Magnetism is no different to how everything works. It's high versus low pressure.
the window clamp can give you a very good idea of how magnetism works. It's simply displaced atmosphere by an object.
As far as magnetism is concerned, it's trapped atmosphere within the structure of the object.

There's a reason why you can gain or lose magnetism due to heat or cold or actually hitting an object hard enough to release trapped atmosphere.

We live in an atmospheric whirlpool that is strongest at the centre and gradually weaker as it spans out in the circle of Earth.

What?
What are you going to do now, go into ridicule mode?
If you do, then explain what magnetism is from your own nut if you think you're clever.

what?
You are aware a magnet can lose it's magnetism, right? Temperature it s a factor, learn about the curie temperature or curie point.

So in your model there is no such thing as an electromagnetic field? Then how do photons of light propagate?

Just wavelengths in the colour spectrum.

Now just remember how gravity is used to describe the pull down of an object and when asked how it happens; guess what?...It can't be answered because it is not known.
It''s not known because it's made up to hide what's really happening.
It's atmospheric pressure upon any dense object. Denpressure is the key to the reality.
It's not something that cannot be explained, either, as I've proved.

The fact that a lot of the globalists don't appear to grasp any of it says a lot about their morals rather than their intelligence.
Some are devoid of basic logic, I know that but others are simply refusing to dare to acknowledge what's been said because they know it destroys the bullshit indoctrinated explanations they adhered to.

Yes, wavelengths of what? Light is a certain range of wavelengths of electromagnetic radiation, that's what!

This despite the fact that gravitation is used in a huge variety of scientific, engineering and commercial activities across the globe.

The fact that gravity cannot currently be explained in terms of why does not mean that we cannot use it to explain how. The mechanics of the effects of gravity are extremely well known and can be utilised extremely accurately.

What has your denpressure actually done? Incorrectly described the displacement of water by solid objects. Brilliant!

We do know exactly how masses attract, though as yet we might not know exactly why, though there a few clues.

I have asked you to explain exactly "why a magnet attracts" and exactly "why electrostatic charges attract". So far you have simply side stepped the issue.

We may not yet know exactly why mass attracts mass, but the fact that it does has been verified experimentally dozens of times. The repetition is simply to improve the accuracy of the important constant involved.

And we know how masses attract in the sense that we can calculate what the attraction will be between two masses.
We can and do calculate the gravitational attraction between a satellite and earth and between spacecraft and other planets.
You get around all this sort of thing by simply denying anything that you can't understand.

What a cop-out! Sceptimatic can't understand it so it can't happen - where have I seen that logic before?
Oh yes, it permeates the whole Flat Earth Society!

What I find so significant is that when you can't explain something properly you then attack our character and honesty. That alone proves that you have no sound argument.

Have a nice day in Dreamland!

Actually you have yet to explain it in a way anyone can understand.  I noticed that when I ask direct, specific questions about your theory, you put me on ignore, and yet others who insult you, just label you crazy, etc, you keep engaging.  Why is that?  I have made an earnest attempt to understand your position but somehow you consider this beneath your time.  However you seem happy to engage those who simply insult you.

Satellites and other space thingies don't exist, only in Hollywood. They go against gravity anyway, so even theoretically make no sense.

They are not needed to understand the principle of huge masses attracting other objects. Meteors, meteorites and orbits of moons (Jupiter, Saturn, our own Moon) are enough.

That would be Disney Dreamland for you, NASA shill. 

Can you post your post again in 10 hours so I can read it while looking at a satellite in the sky?

How do you know that "light in the sky" is a satellite? Ah yes, because some website tells you it is. 

That is not how I know.

Indeed. It's how you believe.

Whatever helps you sleep at night.

What transmits the signals I receive with my satellite dish?  The angle agrees with published calculated information for a geostationary object transmitting over a large area.

Ionospheric reflection has been used before the "invention" of "satellites".

Yes, but the frequency is very different!!1!!!!1!

Nothing easier than just have a converter installed to adjust the frequencies.

Non-real time "satellite" data is gathered using high-flying planes.

That makes no sense.  Dishes have to be accurately aligned to the position of the satellite for both transmissions to and reception of.  Maybe you can give a link to the technical data for your belief.

Dishes have to be correctly aligned in order to work.

That is true.

The "satellite" part is hearsay, that cannot exist physically anyway. Nor in theory; geostationary satellites cannot exist in the first place, as the centre of the Earth is not the centre of gravity.

Satellite towers are positioned virtually anywhere on Earth.

Please give details of these towers.  Dishes point into the sky and work where there are no 'towers'.  I'm asking for a link to technical data such as location, operator, power etc.

Interesting.  So how does gps work in areas hundreds of miles from any possible tower?  Like the middle of the ocean or on the Serengeti?

The dishes are directed to the sky, as that is where the signal appears to come from. Reflected by the ionosphere and sent by satellite towers all over the Earth.
