And yet, while the source of gravity remains a matter of speculation, its effects are so consistent that they have always borne out in every scientific test, 9.8 meters per second squared at sea level. That's no weak force.

I just said we don't know what causes the effect. You're not refuting me at all. However, your response to the absence of information is irrational speculation instead of scientific inquiry.

what do you propose? you claim this force exist, and yet it is to small to test, what is the good in that? people are lost in mathmatics, that isn't science at all, it is just a good bit o' speculation, with no test to resolve.
guess i find it useless, i find it funny, i find it weird, that it is still given and talked about in schools.
much like the core of the earth, which if it is as they say, we've barely see down %1 of the way... yet in school i was taught about facts, things i thought we knew, but it was all just conjecture, no better than making it up.
to me this is the sign, of lies they tell us all, that if things are given absolutely, wrong they must be in all.

Gravity exists. We observe and test its effects to a very high degree of accuracy. Perhaps if you go learn something, you wouldn't claim such nonsense.
Understanding gravity is immensely useful in many applications, construction of every single one of our buildings and bridges, flight, orbital mechanics, space exploration, planetary motion, etc.
What the center of the earth is composed of is not guesswork, it is applying the known rules of physics to the data and evidence we do have, to come up with reasonable conclusions.
To me, your post point to a decided lack in education. Take a peek at this site, it can give you a complete education for free: https://www.khanacademy.org/

your comment fail to see how I accept the phenomenon that gravity is based in. it is the theory around what is happening that I have no use for.
your comment displays a lack of education about what gravity is in relation to physics, if you think it is necessary for building bridges/building/flight .. we can do all those things without having gravity be a invisible force that draws things together.

you don't understand how science works. all that is conjecture, based on theories.
science states until I've actually proven it by experimentation does it become true.
please stop lying to people. because you either know this is true or you are ignorant of what makes truth.

The theory of gravitation is what enables us to safely build skyscrapers and bridges and flying machines.

and the roman empire build many structures without knowing it, because it isn't necessary.
i've seen the aqueducts. they still stand today, and they knew nothing of gravity.

The ancient Romans understood specific gravity of different materials. They understood that water ran downhill. They understood that things have weight and fall to earth. So they knew how much strength a wall must have to support a certain weight. They understood the effect of gravity upon water. So they built very gently sloping water channels from water source to city. The effect of gravity upon water was necessary to make the aqueducts work. They didn't understand the force itself, but they well understood its effects. So they knew some things about gravity. They just hadn't quantified it into formulas.
It is our modern understanding of gravity that allows us to surpass what the Romans built.
