Gyros only detect change in motion.
The laser gyros are accurate enough to detect rotation of earth.
The Gross Ring G is a square ring laser gyroscope, built as a monolithic Zerodur structure with 4 m length on all sides. It has demonstrated that a large ring laser provides a sensitivity high enough to measure the
--->rotational rate of the Earth<---
with a high precision of ΔΩE < 10-8.

lol, as if a motion such as rotating the earth can only be detect by a laser one that we can't check for ourselves. whatever.

Yes, we need such things as gyroscopes because the earth rotates so slowly. I mean for those of us unable to look up in the sky every day and see the sun traveling in a straight line every day....lol.

I'm not interested in the content of this page, but it is clear to me everyone agrees we are spinning faster than the speed of sound.
so your we are going so slow argument doesn't hold up.
please stop lying to people. because you either know this is true or you are ignorant of what makes truth.

Yes, knucklehead the earth is moving at about 1000 mph at the equator. Speed and rotation are two separate things.
The earth can spin only once per 24 hours which is very slow. Take a basket ball and spin it once in 24 hours. Would you say the basketball was spinning quickly or slowly?

you seem to think the earth is very small if you think that one rotation every 24 hours is a small thing.
