Sure! Here’s a quick overview of energy in the universe:
1. **Types of Energy**:
- **Kinetic Energy**: Energy of motion, found in moving objects, particles, and waves.
- **Potential Energy**: Stored energy, such as gravitational potential energy or energy in chemical bonds.
- **Thermal Energy**: The energy related to temperature and the motion of particles in a substance.
- **Nuclear Energy**: Energy stored in the nucleus of atoms, released during nuclear reactions.
- **Electromagnetic Energy**: Energy from electromagnetic waves, including light, radio waves, and microwaves.
2. **Conservation of Energy**: The total energy in a closed system remains constant. Energy can change forms but cannot be created or destroyed.
3. **Dark Energy**: A mysterious form of energy that makes up about 68% of the universe, driving its accelerated expansion.
4. **Dark Matter**: Comprising about 27% of the universe, it influences gravitational forces but does not emit light or energy detectable by current instruments.
5. **Standard Model of Cosmology**: The Lambda Cold Dark Matter (ΛCDM) model describes the composition of the universe as 5% ordinary matter (atoms), 27% dark matter, and 68% dark energy.
