Original: "Space is a huge, mostly empty place with stars and planets scattered like sprinkles. It stretches so far, that's we call it boundless."
Corrected (simple): "Space is a huge, mostly empty place with stars and planets scattered like sprinkles. It stretches so far that we call it boundless."
Corrected (even simpler): "Space is very big and mostly empty. Stars and planets are scattered like sprinkles. It's so big that we call it boundless."
Why:
- The phrase "that's we call" is wrong. We say "that we call" or "so big that we call."
- Don't put a comma before "that" in this sentence. The word "that" connects the two ideas: how far space stretches and what we call it.
- You can also break the thought into shorter sentences to make it easier to read and say out loud.
Try reading the corrected sentence aloud. Nice work fixing it!
