Dark energy and dark matter
Dark matter and dark energy are mysterious concepts invented by astrophysicists in order to explain certain astronomical observations. Dark energy is an anti-gravity that is forcing matter apart and accelerating the expansion of the universe. Dark matter is an invisible matter that has a gravitational effect on stars and galaxies. They are excellent metaphors for the repulsive and attractive forces that must be resolved when designing an architecture.

Dark energy:
There are five dark energy forces that act on subdomains and encourage the partitioning of subdomains into multiple services:
- Simple components
- Team autonomy
- Fast deployment pipeline
- Support multiple technology stacks
- Segregate by characteristics
Dark matter:
There are five dark matter attractive forces that resist decomposition:
- Simple interactions
- Efficient interactions
- Prefer ACID over BASE
- Minimize runtime coupling
- Minimize design time coupling
