3. gravity is not real #2

What you call gravity is just atmospheric pressure ie. weight of air, hence light things float

XF-FW commented 1 year ago

You just made Newton and Einstein cry.

Things float due to buoyancy, which is actually caused by gravity. Objects in a fluid (like water or air) feel an upward force because the pressure is higher from below than from above. The pressure is higher, indeed because of "the weight" of the fluid - which is caused by gravity. If this upward force (buoyancy) is stronger than the object's weight, the object floats. If not, it sinks.

If what you were saying was how things actually work, please, explain to me, how do things fall in a vacuum chamber. It doesn't need to be a hard vacuum either, it can be one of those high school equipment with a simple air pump. Even if you argue, that since it's not a hard vacuum, it still has some pressure and therefore things will still fall, you got to concede that they would fall slower, right? Well, no. If anything, it's actually the opposite - it falls slightly faster, since there's no air friction.

Buoyancy is not caused by gravity but by the liquid itself hence different liquids have different buoyancy. Not based on gravity. In a vacuum chamber as you clearly mentioned there is no air resistance but that doesn't change that matter has weight and density and falls. if it were so and an object was in a vacuum chamber as they say in space it would float not fall. But we can clearly see objects fall in vacuums and not float. You've basically negated space theory!

Things float in space, because they are in orbit, aka at a speed fast enough that they "dodge" the Earth at the same rate they are "falling" - in more exact terms - the centrifugal force equals the gravitational force.

If you do go to the same altitude the ISS is, but with no horizontal velocity and just let yourself go, you do fall, as the gravitational force is not wildly different than the one at the surface.

I don't understand however, how do you say that things fall in a vacuum, while saying that the air pressure is gravity. If what you say is true, how can things fall with no air, if air is what causes gravity?

I have not said air pressure is gravity, I've said this float or sink is based on density, and the force that makes thing. 'fall' at different rates is atmospheric pressure. Everything about space is made up hence why I can't debate on it. You can't debate a made up thing, it will win by its own rules

You kinda started with it.

I mean, you can see it. You can literally buy a telescope and see the moons of Jupiter (bright dots really), you can see the craters of the moon in detail, you can see the phases of Venus, you can see nebulas, galaxies, etc. With the right (amateur) equipment, you can even see sunspots in the Sun.

There is the firmament and stars that are on the firmament that's a completely different thing from space

I didn't say Atm is gravity I said its what people presume is, gravity has never been will and never be

XF-FW commented 1 year ago

Ok, how about planets? They move along the firmament. They're not "static" as the rest of the firmament.

thegliche commented 1 year ago

They are static, As I pointed out star constellations have always been static hence why they have always been used as navigational instruments, plants are stars, or people pick out stars and calling them planets.

XF-FW commented 1 year ago

You can see them move day after day. Literally, just look up in the night sky, in different days and see how they move in regard to the "static" constellations.
