My question to Gemma 4: what was the Einstein theory? Explain this extremely short.
Answer:
It's not one single theory, but a set of theories that redefined our understanding of space
and time:
1. **General Relativity:** Gravity is not a force, but the curvature (warp) of a fabric called
**spacetime**, caused by mass and energy.
2. **Special Relativity (E = mc²):** Energy (E) and matter (m) are
interchangeable, related by the speed of light (c).
**Extremely short summary:** Mass warps spacetime, and this warping is what we feel as gravity.
