T-Mass and Core Density#

In Antigravity cosmology: Total System Mass (T-Mass) and Core Gravitational Field (Core Density / Heavy Nine). In standard terms: Aggregate market capitalization of the NASDAQ-100 universe and concentration metric in mega-cap issuers (>1T USD).

What is T-Mass#

T-Mass (Total Mass) is the aggregate market capitalization of the 100 constituent issuers of the NASDAQ-100 index expressed in USD Trillions.

  • NASDAQ-100 Universe (Not just tech): The index comprises the largest non-financial companies listed on Nasdaq — containing consumer discretionary leaders (Amazon, Tesla), retailers (Costco), and healthcare/biotech alongside pure technology companies.
  • Valuation Delta (Repricing): The session change in T-Mass (24h Delta) measures aggregate market valuation repricing, not net external cash inflow. When share prices rise, market capitalization expands without requiring equivalent dollar amounts of cash to be deposited into the market.

What is Core Density#

The Core (Jądro) is the dynamic cohort of NASDAQ-100 companies whose individual market capitalization exceeds $1 Trillion USD (historically and narratively referenced as Heavy Nine):

  • Core Density (%): Percentage share of total index T-Mass represented by >$1T companies.
  • Gravitational Dominance (> 50–60%): Extreme index concentration. When a handful of Core companies accounts for over 60% of total mass, their price movements dominate index returns over the remaining 90+ peripheral constituents.
  • Core Membership Shifts: A company crossing above the $1T threshold (singularity emergence) or dipping below it (gravitational collapse).

Average Share (Peripheral Temperature)#

Telemetry also tracks the Average Share:

  • Calculated as the unweighted (equal-weight) nominal share price average of non-Core peripheral constituents.
  • While nominal prices depend on share counts and stock splits, its daily delta serves as a quick proxy to verify whether the broad periphery is participating in index expansion or if market gains are concentrated exclusively in mega-caps.
