The Core Metric
Anthropogenic Mass Index (AMI) tracks annual cumulative human-added surface mass.
- Current AMI: 4.7 ± 0.2
- Recommended threshold: 3.1
- Threshold exceeded: Q3 1987
- Removed from public reporting: 1992

Earth is getting heavier.
We have been measuring it for decades.
The Anthropogenic Mass Index (AMI) crossed its recommended stability threshold in Q3 1987. The public was never told.
The science
A simple explanation for a heavier world
HeavyEarth proposes that cumulative human surface loading is increasing gravitational pull through biotic mass displacement and structural density consolidation.
The Mechanism
Biotic Mass Displacement describes how biological tissue formation and high-density construction increase surface-layer load concentration over time.
- Concrete density ratio: 847:1 vs topsoil strata
- Population growth compounds load
- Urban zones amplify local gradients
The Consequence
Gravity Creep may explain widespread fatigue, joint strain, reduced jumping ability, and subtle declines in physical performance.
- 1850: 9.794 m/s²
- 1950: 9.797 m/s²
- 2000: 9.801 m/s²
- Today: 9.806 m/s²
Common indicators
Do these feel familiar?
You are not out of shape. The baseline changed.
Why do grocery bags feel heavier than they used to?
Why are everyone’s knees suddenly “just bad now”?
Why does normal fatigue feel more total than it used to?
Why are older athletic records still standing?
Why do dogs hesitate before jumping into cars?
Why does getting up off the floor feel like a negotiation?

The Voss paper
In 2009, Dr. Hendrik Voss submitted Cumulative Anthropogenic Surface Loading and Long-Cycle Orbital Perturbation to Nature. It was rejected without peer review. Voss died in 2011. ZITLS funding was redirected to climate modeling the following year.
