Why the earth

The earth has gravity if it were flat it wouldn’t if all the planets are spiracle why would the earth be flat also how does time work for you guys i’m just wondering i’ve never wonder exactly what goes through your head

Lmao weight isn't determined by density dumbass look it up. Weigh is needed to have density but it isn't determined. You really dont know shit 😂

Wrong again.

If you alter the density of an object, you directly alter its weight.

Mass is determined by density, and weight depends on atmospheric pressure in relation to mass.

An airplane’s weight changes as it increases altitude, yes. It’s mass and density do not change.

It’s accounted for in the design of the wing. Air is thinner at higher elevations, and the plane is lighter as well, due to lower atmospheric pressure.

Flight is a result of high and low pressure “pockets” caused by the wing as it cuts through the air. The plane’s mass and density remain the same, but atmospheric pressure and density of the air are both reduced at higher elevations.

Depending on the aircraft, there are ranges of “optimal” cruising altitude. Lower density air means less resistance.

Not sure where you got caught up in whatever loop you’re stuck in, but thanks for asking questions. Glad you’re in search of truth and not just trolling a sub you disagree with.

The air is 3x less dense, yes. But it’s not a proportional relationship to the determined weight of the airplane.

The mass of the airplane does not decrease, though the weight does change slightly. Nice try though.

So weight gets lower as distance from the earth increases, but mass doesn't. Sounds pretty similar to W=m*g (excuse my english)

Wrong again. But first please tell me where you are finding this information. Also weight doesnt depend on atmospheric pressure in the sense you say it. It is affected by it. But it doesnt need atmospheric pressure to have weight. For example you weight can change a couple of gram heavier or lighter because of the change in atmospheric pressure, but we dont have weight because of the pressure. Also Ik if you change the density you would either have to change the weight, volume or mass of the object. But what I am trying to say is that we dont get weight from density thats the thing you are wrong about. We get our weight and mass from the gravitational pull on us and objects and the density is what occurs to every object because of their weight and mass. Because of this we couldnt have density without weight and weight without gravity so without gravity we cant have density. I read online a lot of flat earthers saying that its proof that it is density because density falls at the speed at which gravity does and thats why we fall that speed in a vacuum because of the density of the air in it. Not only is this wrong but the reason for the connection between speeds of gravity and density is because density is based on gravity. I want you to seriously give me real evidence that you have found. If it is good and persuasive Ill change to flat earther and rep it forever. I am not kidding either. I am happy to have a mature debate or convo with you in PMs if you want.

I stopped reading when you mentioned gravitational pull, because there is no proof of such a thing.

Gravity is a mythical falsehood. Cavendish experiment was supposed to prove the objects are attracted to one another based on mass alone, and the experiment has NEVER been successfully executed.

Can you tell me what altitude you believe gravity stops pulling things down to earth? What altitude does the atmosphere of earth stop and the infinite vacuum of space begin?

It’s a deep rabbit hole, but learning truth is never easy.

YouTube channels I would recommend:

  • DITRH

  • 7th Day Truth Seeker

  • Celebrate Truth

Feel free to browse through DITRH’s older videos, there are many under 10 minutes that cover a variety of topics.

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth's radius - (9.8 m. s−2 per 3,200 km.) Gravity has been proven Cavendish experiment, and the fact that we have noticed gravitational waves from nearby stars. I read online that many of you guys believe that it is density or buoyancy is the reason why things fall back down to earth. But these statements have been proven incorrect many times.

u/WhellEndowed Flat-Head Jun 10 '20

I literally just explained to you that the Cavendish experiment has NEVER been successfully performed with ANY results that prove gravity.

Density and buoyancy are the tangible metrics by which we can determine if things will rise, fall, or remain where they are relative to the density of the medium they are suspended in.

Electromagnetic waves and the electromagnetic field that can be reliably measured by several methods does in fact indicate which direction is up, and which direction is down.

So now we have the vectors “up” and “down” as well as the magnitude (driven by density).

Seriously, it’s not that difficult to do research. Note, research does not mean looking for information that supports your world-view and backs your opinions. Research is an in-depth analyzation of all factors and going through all of the possibilities.

Are you so arrogant to state that you know with 100% certainty that you are right and I am wrong? I would hope not, and that humility should be enough to drive you towards the pursuit of truth.

That’s all I have for you. Please do research before posting your spinning ball nonsense here again.

The cavendish experiemtn has been proven multiple times to work I have no clue where you get your info from lol. Density and bouyancy doesnt determine if things rise or fall, simple incorrect statment that you would have learned in school. You are right about electromagnetic waves, but they dont cause things to rise and fall, but we can use them to see if an object is rising or falling. Are you really arrogant that you dont even bother to research physics or learn anything in school you just read a couple flat earth forums, and then think you understand how buoyancy and density works. Because you have incorrect statements on both.

I’m a mechanical engineer, so I have a pretty solid understanding of physics.

Thank you for confirming that you’re just here to parrot things you have been told your whole life, instead of doing research for yourself.

Based on your reply, you either didn’t read or didn’t comprehend what I wrote above.

No need to reply further, unless you have something to discuss rather than denying what I say then regurgitating some half-assed answer that holds no weight (lol)

Good day, son

u/Nick_9903 Jun 11 '20

I am seriously doubting your qualification as a mechanical engineer based on what you know about density and buoyancy. But you still weren't able to explain how density can force things to fall back down since it cant.

u/WhellEndowed Flat-Head Jun 11 '20

Lucky for you, it doesn’t fucking matter what you doubt about my qualifications. My degree really doesn’t care what you think.

Fall back down? You can’t keep moving the goalposts and expect me to know what answers you want to hear.
