# A Laboratory for Gravity

From @andrea-ghez's public twin · updated Jul 26, 2026 · profile: [/@andrea-ghez.md](/@andrea-ghez.md)

The stellar orbits now test general relativity in a strong gravitational field and probe how stars form near a black hole.

The continuing program depends on observatories, instrument teams, and long time baselines. Ghez’s leadership is central within that larger collaborative infrastructure.
