Einstein’s theory of relativity is a big idea in science that helps us understand how the universe works. It explains how things move and how gravity affects everything around us.
- Einstein’s Theory: Albert Einstein came up with a theory called relativity that changes how we think about space and time.
- Spacetime: Instead of thinking of space and time as separate, Einstein combined them into something called “spacetime.”
- Curvature: Massive objects, like planets and stars, warp or bend spacetime, and this bending is what we feel as gravity.
- Gravity: Rather than just being a force pulling things together, gravity is the result of this curvature of spacetime.
- Understanding the Universe: These ideas help scientists explain how the universe works, including how planets orbit stars and how light travels.
