Megaengineering
Megaengineering refers to the design and implementation of extraordinarily large-scale engineering projects that manipulate environments on a planetary or even stellar level, such as building space elevators or terraforming Mars. This field blends cutting-edge technology with speculative science, often inspiring real-world innovations while highlighting the ethical challenges of altering ecosystems on a massive scale.

One of the most ambitious megaengineering ideas, the Dyson Sphere, could theoretically enclose a star to capture its energy output, providing up to 400 septillion watts—enough to power a civilization far beyond Earth's current global consumption of about 20 terawatts, as envisioned by physicist Freeman Dyson in 1960.
