Study of matter, energy, and their interactions in the universe.
Albert Einstein’s Theory of Relativity showed that time and space are linked—and both can stretch and shrink! When you move really fast (close to the speed of light), time actually slows down for you compared to people who are standing still.
The most famous equation ever: \( E = mc^2 \) (energy = mass × speed of light squared). This means a little bit of mass can become a lot of energy!
Relativity helps us understand black holes, GPS navigation, and how the universe works on a cosmic scale.
\[E = mc^2\]
A GPS satellite’s clock runs slightly faster than clocks on Earth.
Energy released in nuclear reactions comes from a tiny bit of mass.
Einstein’s relativity shows that space and time are connected, and energy and mass are two sides of the same coin.
