Physicists are debating again whether the universe's expansion is really accelerating — a claim that has long been a cornerstone of cosmology. How much does this shake your trust in the big scientific theories?

Kozmológusok között új vita robbant ki arról, hogy a szupernóva-megfigyelések valóban alátámasztják-e a régóta elfogadott elméletet, miszerint a világegyetem tágulása gyorsul.

• Not at all — that's exactly what makes science strong: it reviews its own results
• A little — it makes me curious how the debate will end
• Quite a bit — if even this is in question, what else can we be sure of?
• It doesn't surprise me — I already had doubts about the big cosmological models
