Um.
GRACE-FO tracks changes in how mass is distributed within and between Earth’s atmosphere, oceans, groundwater and ice sheets.
GRACE-FO tracks "...Earth’s water movement and surface mass changes across the planet. Monitoring changes in ice sheets and glaciers, near-surface and underground water storage, the amount of water in large lakes and rivers, as well as changes in sea level and ocean currents provides an integrated global view of how Earth’s water cycle and energy balance are evolving..."
That says nothing about the total mass of the Earth.
Your core premise is flawed.
Thank you for your detailed analysis. I'd like to add the following:
You're absolutely right that GRACE-FO does not directly measure the total mass of the Earth, but rather tracks the redistribution of mass — especially related to water, ice, and near-surface layers. However, on NASA’s official website and GRACE-FO project pages, they clearly publish graphs and datasets showing that
Earth is losing mass every year, primarily due to
ice melt in Greenland and Antarctica, as well as groundwater depletion in many regions.
So even though they don’t explicitly state how much the total mass of Earth is changing, they
do show that mass is being lost annually in significant parts of the planet.
While current physics models consider this merely as a redistribution of internal mass,
NKTg proposes that this contributes to an actual change in total mass — and that this change can be detected via orbital parameters (distance, velocity) published by NASA.
In summary, I do not deny the importance of GRACE-FO — in fact, its data
also supports the observation that Earth is losing mass year by year. NKTg simply adds another perspective: that this is not just internal redistribution, but a
real, measurable change in total mass, and this can be verified using the NKTg formula with publicly available data.
