Ancient Human Bones Take a Trip to Space
cross the line: to do something that is wrong or unacceptable
A piece of our planet’s distant past has recently orbited the Earth. Virgin Galactic took two pieces of bone from our human ancestors into space on September 8, 2023. One was a collarbone from a human-like creature that walked our world two million years ago. The other was a thumb bone from a different ancestor, 250,000 years old. Space tourist Timothy Nash carried these bones on the flight. Some say it was a way to honor our ancestor’s spirit of invention. But many scientists think sending the bones to space crossed the line. Geologist Robyn Pickering said, “To treat ancestral remains in such a callous, unethical way — to blast them into space just because you can — there’s no scientific merit in this.”
1. I thought we were friends, but secretly recording our conversation crossed the line.
2. The fans were yelling loudly, but when they started yelling racial insults at the other team, they crossed the line.
3. At work, when the boss yelled at Emma in front of everyone for a small mistake, that crossed the line between being strict and being unfair.
