How birds fly and defeating the gravity

Its vice versa, global can’t be exist without gravity because all the rounded earth rules built on the gravity

You’re absolutely right. Please be aware that your statement “globe can not exist without gravity” is the same as “globe exist because of gravity”.

I mean the rounded earth theory cant be exist without gravity!!!
and for me since I was 15 years old till now 35) away from if its flat or rounded (I never agree or believe in the gravity)

Its my thoughts (and I think no one can control my thoughts) except myself 😁👍

True, no one but you can control your thoughts, but your thoughts have no effect on the reality of gravitation or on the shape of the earth.

Rabinoz is right. You thoughts are yours alone.

But back to gravity (because we’re just getting started). If you don’t believe in it, what force do you think makes a rock fall back to earth when thrown. Or, to keep in line with the OP, why do you think birds flap their wings while flying?

Thanks, yet I wonder how a tiny ballon filled by helium Can beat the Gravity power! I wonder if there is a satellite will not be grabbed to the moon or sun or the earth because of the gravity of all of these objects.

If you feel that Im stupid please stop answer  but if u feel that you need to answer me, so please go ahead

If Gravity exists How birds can fly and easily without power motors??
Please don’t explain the birds biomechanics but explain it from the gravity point of view
I’m Waiting logic/scientific answers

They use their wings to push themselves off the air.
When they fold their wings they fall just as everything else.

It means because of the air and the Density or the gravity or what? Really Confused!!! Since I was 15 years old hahahaha

The air in the helium balloon is lighter than the air around it so the air around the helium balloon goes down and at the same time pushes the air pushes balloon up.

and in your answer you didn’t mention where is the gravity factor!! So in this case gravity = Zero!!

Carefull, you are beginning to sound like Intikam.

Gravity is the attraction between 2 masses (trying to dumb it down please).  The heavier the mass, the greater the gravitational attraction. Helium has less mass than air (still dumbing down) and so the attraction between helium and earth is less than the attraction between air and earth. So the air pushes the helium out of the way in its rush to get closer to the earth which makes the helium go in the opposite direction which is up. It's like trying to push yourself to the front of a queue. You must push someone else back.

First I don’t know what Intikam means!!

Second do u mean heavy things will go down faster than lighter things because of the air pressure and the gravity??

Again if u feel that I can’t understand or stupid, so no need to waste your time with someone can’t understand 😁 but if u need to help just ho ahead and explain more
Thanka all

It’s indeed not the same with satellites. The difference is that a satellite is constantly falling towards the earth because of gravity (they do not operate in a zero-G environment) ... but because they are moving so fast, they “miss” the earth constantly and remain in orbit.

Satellites are also very well affected by gravity. But there are multiple forces at play, something flat earthers don't seem to want to understand.

Gravity oulls the satellites down. But the satellites have a foward speed which creates a centrifugal force away from the earth. When gravitational force going down is balanced by centrifugal force going out, the satellite remains in a stable orbit around the earth.

If the satellite cannot maintain its foward speed to create that centrifugal force, its orbit begins to degrade and the satellite begins to fall. Exactly as happened to the Chinese space station that crashed a while back.

Intikam is a flat earther here currentlr known as Brotherhood of the Dome. His arguments boil down to "I don't understand so I win so the earth is flat". Look him up.

Yes, heavier things (things with more mass) fall faster on earth because they are more able to overcome the drag caused by the atmosphere. They can as it were force their way through the crowed more quickly than light things.

However, there are still other factors at play. The shape of the object, the surface area of the object, things like that affect the speed an object falls through the atmosphere. Which is why a multi ton aurcraft that losses its engines in flight will fall slower than the lighter pilot who jumps out of the cockpit. Its shape thanks to its wings give it more lift to counteract the drag of the atmosphere and helps it "fight" gravity a little longer.

No. People knew it was round long before they understood gravity.

Thanks, yet I wonder how a tiny ballon filled by helium Can beat the Gravity power!

So what you mean is you have no idea what you are talking about at all and instead just make up pathetic strawmen to pretend there is a problem.

Helium doesn't beat gravity. It loses.
Air wins, falling down, pushing the balloon out of the way.

If you would like to know how gravity factors into it, consider an object with a density of po, in a medium with a density of pm.
This object can be approximated as a cylinder (or a series of prisms).
It has a height of h, and a cross sectional area of A.

At the top of the object, the medium has a pressure of PT.
At the bottom, due to gravity, the medium has a pressure of PB=PT+pm*h*g. This is because for a given area (a), the weight of the air in the column is given by F=m*g, m=pm*V, V=h*a.
F=pm*h*a*g.
The pressure due to that is P=F/a=pm*h*g.

So at the bottom you have that extra pressure.

So the object experiences a downwards force of Fd=PT*A+po*A*h*g (this last part is m*g for it).
It experiences an upwards force (from the bottom) of Fu=PB*A=(PT+pm*h*g)*A
Thus the net force (upwards for simplicity) will be Ft=TFu-Fd=PT*A+pm*h*g*A-PT*A-po*A*h*g
=A*pm*h*g-po*A*h*g=A*h*(pm-po)*g=V*g*(pm-po).

For objects much denser than the medium they are in, they sink. Otherwise they rise.
This is different to the normal idea of all objects beings accelerated equally.
However, the density of air is roughly 0.0012 g/ml. The density of most other objects are much higher. Water is 1 g/ml, so that tiny difference doesn't normally effect it. But for some objects, like balloons it does. (There are also issues of air resistance as it moves).

If you feel that Im stupid please stop answer

I will answer regardless so others can see the answer.

Thanks all
I’m not pretending but when I watch some videos from NASA VS FE talking about same topic like gravity From my point of view both are right BUT NASA depends on broken rules and FE depends on new rules then I think the pronlem comes from the old centuries not us as I think til now many many many things still undercover

Again thanks all for your time

Why do you say, "NASA depends on broken rules"? What "broken rules"?
The basic that NASA and other space agencies are exactly the same as have been used since Newton's time.
I know that Einstein extended "Newton's Laws of Motion and Gravitation", but it is still Newton's laws or rules that are used in almost all practical calculations.

You know how a fan pushes air right, it redirects it with its blades. The bird does the same thing pushing down the air so that it itself will rise.

Compare it with swimming, just in the air where you need more speed.

You have probably heard the saying in physics, that every action has an opposite and equal reaction. The bullet firing from a gun pushes just as hard on the gun firing it.

Thanks, but where is the gravity rule here? and there are many birds floating on the air without doing any action (just float)

they are still moving forward and still creating lift with their wings. 

Thanks guys and please don’t copy/paste from google 😁

Thanks guys and please don’t copy/paste from google 😁

I question things but one thing I can't get past is that I have friends who have done the "Cavendish experiment" and measured two heavy balls attract each other. So they tested gravity. I saw the setup and the balls. If this was a lie then there has to be a big conspiracy by all schools, where they build expensive devices to trick us. Is that going on?

PS, the earth can still be flat even if gravity is real, also.

tomato:
Yes but it can’t be rounded in case there is no gravity for that the point I think

And if we learned wrong things so we will fight for this mistakes because we are thinking its the right things its not about the devices but its about who invented such devices and control everything in our life.

Its my thoughts as I said before

Thanks for your participation

I think the problem is you have let people with no proof, none or little knowledge and outright trolls convince you that basic scientific facts understood for centuries, are wrong. And that NASA lies.

Truth is the existence of NASA and all 71 other space agencies conclusively debunk the existence of a flat earth. Basic science proves a spherical earth. The combination of low knowledge, little understanding and a desire to feel important and superior is what drives the flat earth belief.

My advice, spend time watching flat earth debunk videos on you tube. Ignore the religious condemnations most of them sprinkle their videos with and learn only the scientific facts.

Satellites are out of the air, above it.
They stay in orbit because of centrifugal force that keeps them there.
Every curved trajectory is curved because of external force (gravity) and inertia is opposing gravity with centrifugal force.
F = m v² / r .

Is it really called centrifugal force when its the objects speed providing the opposing force?
I always thought you needed an external object providing the speed for centrifugal force, so I've never seen it defined as anything other than trajectory and orbit.

No. NASA depends upon rules which describe reality quite well.

FE relies upon nonsense which doesn't match reality.
If you wish to claim the rules NASA uses are broken, PROVE IT!

UNIVERSAL ACCELERATION. 

UNIVERSAL ACCELERATION. 

What creates it?
Does it mean the earth is accelerating upwards?
If that is the case, then try calculating its current speed just over the last 2000 years.
You will see why most flat earthers are heading towards boyancy and weight for their logic.

6000 years if counted from Adam.
There is unknown era before Adam.
The current speed is unimaginable. Some trillions km/s is too slow.

Up-down force & attracting force are debunked by paralel objects (especially in vacuum) with different masses that hit the earth at the same time.
>> the lighter object is supposed to first hit the earth.

It's not the objects that fall.
It's the earth that hit the objects.
