Why don't we feel the centrifugal force of Earth's revolution around the sun?

You are saying that if you are moving constantly, no jolts, no bumps, you don’t notice it? This is like, moving through space?

I’m sorry I assumed you were a physicist.

Yes, it is called the principle of relativity. If you travel with a constant linear velocity you can not tell the difference other than looking at the background. But that would be assuming there is no air resistance. But a circular or elliptical motion has a centripetal acceleration, so you would experience psuedo forces. If we do experience them on Earth, which natural phenomenon are caused by them? Rotation of earth explains Coralis forces, but I am asking about revolution.

I understand what you are saying, only a little bit.

I would have to look all this up:

Principal of Relativity

Makes sense

Circular or Elliptical Motion

I know nothing

Centripetal Acceleration

If it’s one constant speed, why are we accelerating. This doesn’t make sense to me.

pseudo forces

I don’t know anything about this.

which natural phenomenon are cause by them.

I don’t know, I dont know anything about them.

rotation, Coralis forces; asking about revolution

I know nothing.

Here’s what I do know:

We have GPS. We have airplanes. We have cellphones. We have satellite imagery. Why are they lying to us?

I’m happy to have a conversation about these things. I’m willing to keep an open ear. And I know about the glass dome theory. Like the firmament? Or what’s it called, in the Bible?

Feel free to share what you know. I often look stuff up in google and don’t require citations. I love to learn.

But I am very skeptical of flat earth and the dome.

Since velocity is a vector (has both direction and magnitude) going at constant speed in a circle means you are always changing the direction, hence the velocity. So it is accelerating.

I’m not a flat earther, but the intuition contradicts the math. If we went by intuition we would wonder what holds the atmosphere together.

Magnetism? Gravity? What does hold in our atmosphere?

This is over my head.

What is your point? Like what are we getting at?

That your mistake was assuming I am a flat earther because I asked this question.

That’s fine.

But what are we getting at?
