A blockchain is a distributed digital ledger, a spreadsheet duplicated across a network of computers, updating simultaneously without a single controlling entity.

Immutability leads to safer, more predictable, and parallelizable code, critical factors when working with distributed systems like Apache Spark.

Aristotle viewed the universe as a set of celestial spheres, with the stars in the outermost perfect, incorrupt, and immutable sphere, providing a sense of constancy amidst Earth's changes. Galileo's discoveries challenged the notion of perfection, revealing imperfections and different centers of the cosmos.
