Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the conceptual originator?Robert L. Forward
2. What is the proposed propulsion mechanism?Onboard laser arrays driving external light sails
3. How does Inkha move through space?It uses powerful lasers that shoot light onto huge, thin sails, and the light pushes the sails to make the whole structure go forward.
4. Why would Inkha be useful for exploring other star systems?Because it can travel very fast, maybe a good fraction of the speed of light, so it could reach stars like Alpha Centauri in a few generations instead of thousands of years.

Megastructure: A hypothetical, extremely large artificial construction, such as a space habitat or Dyson sphere.
Interstellar Travel: Voyages between star systems, involving vast distances measured in light-years.
Light Sail: A proposed propulsion system that uses radiation pressure from photons to push a spacecraft.
Tyranny of Distance: The immense challenge posed by vast spatial separations in space exploration and colonization.
