Momentum and space and gravity and stuff

The universal law of gravitation states that the force is inversely proportional to the distance squared. So depending on how far you are from the center of mass, it will change but the variation of these magnitudes is very small for us. You feel the resisting force on your feet everytime you stand.

Most have seen this, but still funny, and has to do with momentum.

I forgot about this gem

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?

People have just started noticing censorship - but did you know the US Government held hearings with Google/Youtube in 2013 over why they weren't censoring "flat earth" videos?

Most are delisted/Monetized or outright deleted - same goes for Google's algorithm. What DOES exist is nonesene - The Flat Earth Society are anything but - it's a honeypot to catch curious people and give them erroneous information to make the position seem even more ridiculous than it already appears.(and trust me, I know it sounds ignorant!)

So with me telling you that - I don't have all the answers, I find out new things everyday. I did stumble across the explanation a few weeks ago, but I'll have to find it.

The radio towers for instance are a strength for FE - the claim is radio signals are able to travel the distance they can because of the level earth and longer wave length. There is also the datapoint that 95% of all telecommunications are run through cable - so it's just the final transmission run from radio towers

Again, don't take it as I'm attacking you - but how was this measured? The current FE explanation for "gravity" is 'density' and by changing the density of an object, it causes it to rise of fall - there isn't a "gravity at all.

What are you trying to measure? Gravitational acceleration of the earth? Galileo figured it out around 1600 by experimenting with rolling spheres of different mass down inclined planes.

You can drop a rhinoceros and a thumb tack from the same height in a vacuum and they'll both hit the ground at the same time.

Or are you trying to hold a particle in your hand called gravity (or a graviton) that tells you what he's doing? No offense taken, I also questioned everything while I was studying structural engineering and used the scientific method to confirm everything in a lab. Accepting answers blindly is a waste of mind but with that being said, there isn't even a drop of doubt that we landed on the moon lol.

Say you have a spaceship that generates its own gravity. Not by rotating, but "magically" like they do in Star Trek and the likes. This ship is your source of gravity. If the ship suddenly moves in any direction, do you feel the affects of that as if you would in a car?

I've read a lot on this and found a lot of yes answers, but none of them stated the ship as being the source of gravity.

I did find some things on proper acceleration vs coordinate acceleration, proper being acceleration that deviates from the local gravitational field, and coordinate being acceleration with respect to some fixed point. Humans feel proper acceleration, which would be like being on Earth and accelerating in a vehicle. The vehicle is deviating from the gravitational pull of the Earth. But humans would not feel coordinate acceleration, which is what I would think fits the scenario of a moving ship thats generating that gravitational pull.

gravity does not exist in my mind, well, not a single scientist knows what it is

Hmm

The black hole you harness to generate wormhole for FTL travel will act as the center gravitational source of "artificial" gravity.

For our flat-earth person, have you ever watched a ship with sails head for the horizon? The mast slowly disappears as the ship goes over the curve.

No it doesn’t - it goes into the horizon. You can prove this with any high zoom camera.

If you believe in "curvature" this is impossible. Isn't the formula 1 mile =almost a foot of drop? Yeah...ok.

I see the gravitational effects of another object every time I have lunch at a nearby sea port. The tides come in and the tides go out, thanks to the moon.

They come in and go out regardless of a new moon or not.

3.0 didn’t say anything about a new moon or not…

A new moon implies the moon isn’t present in your local sky - though, during a new moon it’s not visible at all anywhere, so how is it impacting your tides? They change twice a day like clockwork - ‘gravity’ has nothing to do with it.

Wow

Yeah.

People have strong opinions, most of the time I’m finding it’s misplaced

Your own link above clearly states that the moon and sun have an effect on the ocean tides. It also states there are other factors as well; neither is exclusive.

You are certainly entitled to your own opinion and I believe your opinion boils down to mistrust of science and government.

I said the tides go in or out regardless of the location of the moon, and the link supports that.

My mistrust is based on inconsistencies in the narrative - I’m not sure how grown adults (myself included) just regurgitate this stuff without thinking what we are saying.
