![“Gravity acts on all forms of mass and energy, but energy comes in a host of very different forms that behave in peculiar ways that were not known in Newton's day. Wotst of all, gravity gravitates. Those waves of gravity that spread out, rippling the curvature of space, carry energy too and that…” quote by John D.

> ““Gravity acts on all forms of mass and energy, but energy comes in a host of very different forms that behave in peculiar ways that were not known in Newton's day. Wotst of all, gravity gravitates. Those waves of gravity that spread out, rippling the curvature of space, carry energy too and that energy acts as a source for its own gravity field. Gravity interacts with itself in a way that light does not.””

## About This Quote

This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.

Gravity influences all mass and energy, and its own waves carry energy that further curves spacetime, creating self‑interaction unlike light.

**In simple terms:** Gravity can act on itself, unlike light.

Key Takeaway

Recognize gravity’s self‑interaction in physics.

Themes
