How surprised are you that, according to the James Webb Space Telescope, carbon and oxygen were already escaping early galaxies into the universe just 500 million years after the Big Bang?

The Nature Astronomy study suggests this much-earlier 'enrichment' may have erased traces of the very first stars.

• Very surprised — it rewrites what I thought about the early universe
• Interesting, but it doesn't change the big picture for me
• Not surprised — science keeps refining these details
• Skeptical until more measurements confirm it
