You dont have any pints

I just want one flat earther to tell me how a submarine in WWII was able to use a gyrocompass to navigate from america to europe

What calculations and experiments did you do to conclude the earth is spinning and how do you know these gyros were built using real world calculations and observations of a spinning earth to determine where true north is?

the mere fact that they had to design the gyrocompass with mercury weights that adjust themselves to adjust for precession

as for what i have done

i have been at the top of a mountain

and had to look down at the sun as it set

which would be impossible unless the earth was round

now

^^

how could a gyrocompass possibly work on a flat earth

So its just a fact to you because of mercury weights?

Interesting

yes

the mercury or oil weights that adjusted themselves based on rates of precession on each side

Ill have to look more into it. I just dont see how this proves the earth is spinning or round

Assumed precession which could be something else?

you would have to explain what on a flat earth is causing a 55 pound gyroscope to move against its momentum

I wouldn't have to explain it

You would

The earth is flat

at a rate that is perfect with where true north is

nah

you would have to

my claim is that the earth is round

Its your claim it works a certain way

and there is no force causing the gyroscope to move against its momentum

allowing it to maintain its own z axis

but your claim is that it is flat

so you would have to be the one that explains how a gyroscope could possibly be moved against its momentum

regardless of which direction the ship is moving

to always point true north

I can prove its flat through direct measurements and observations

You are trying to use indirect ways to prove the globe

you have gotten a 3 mile straight ruler?

Yes essentially

Its called binoculars and math

so you arent really measuring anything

Yes you are

Parabolic drop or lack of

so what did you do with the binoculars
