Weight or mass?

Mass = no.

We're in space though - weight ~ 0.

Or do you mean a regular airplane?

Well, the OP was yakking about artificial gravity in some space vehicle, or something.

But yeah, a regular airplane that is burdened by gravity.

Flying is just falling and missing the ground, weightlessness is almost the same thing.

Well I would imagine if you put the plane on a scale and the fly is flying around its weight would not count. However once it lands on some part of the plane then it's weight would count.

Like the vomit comet astronauts use for training.

Unironically, I don't 'believe' in gravity, space or any of that (as of this year. I became a biblical flat earther) but I'm just curious at what's being said.

How much mass is needed to create a gravitational force?

Anything with mass has a gravitational field, even you, but gravity is a really weak force, so it takes moon sized (for example) objects to have a significant amount.

Then yes, the aerodynamic force of the fly's wings to keep it afloat will add to the weight.

It's not just mass. It's the product of masses inversely proportion to the square of their distance.

If you're asking how much mass is required to curve space time, then the answer is any mass. The gravitational field would just be infinitesimal when you scale it to planets. Frame of reference is important.

Oh?
How do you measure it? How many times does the gravity a car produces vs a person? Or a mountain? Do we see examples of this?

not being snarky, serious question.

There are equations, but this is beyond my understanding of math.

Added picture of the deflection of space with the earth. The more massive the object, the more it deflects space, the more space pushes down (gravity).

I have read that the pull of Earths gravity varies depending on density and where you are on the planet.

Of course, where would you like me to start (and again, none of this is sarcastic) I mean, I believed in what you do currently my whole entire life, so it's not something I was raised with.

But basically, I had a wakeup call where I started to question everything. I did some true research into what we believe collectively as a society and realized that much of what is taught as fact, is actually theory treated as fact, where the details are claimed to be too complex for people to understand.

For instance - you, I or anyone else have literally ever ever ever seen the curvature of the Earth. You can use a high powered camera and see over the horizon at ground level and see objects - which implies they are not moving over a "curve" but actually by perspective.

I've seen the moon landing (available to anyone who wants to watch on Youtube) and it's some of the fakest, worst special effects (good for the 1960s) I've ever seen. Pictures of Mars taken Devon Island, astronaut on green screens, no actual unedited pictures from Earth - faked perspective photos, etc etc.

And yes, I have examples of every single one of these and more.

Again, not trying to be rude - is there a device that can actually measure gravity?

Weight = mass * gravitational acceleration

Therefore, mass = weight/gravitational acceleration

Since we use a constant 32.2 ft/s2 or 9.81 m/s2 for gravitational acceleration, the weight of each object is proportional to its' mass.

If a car is 5000 lbs and a person is 100 lbs then the car is 50 times more.

Yes. With a scale.

Places like the NASA Glenn Research Center, can do micro gravity tests.

Interesting. I know theres plenty of questionable "facts" out there. It's always fascinating to hear other peoples views on this.

Regarding not being able to see an actual curve of the Earth, what about things like having to account for curvature of the Earth in long distance shooting, or tower heights for long distance radio transmissions, and the likes?

So I'll ask - has anyone actually ever seen or felt the gravitational pull of another object? I remember 9.8 m/s from physics, but my understanding was that was actually an average and not a constant value.
