Passage Summary: Light and tiny particles from a star explosion hit Earth at the same time. Scientists think this proves space is curved, just like Einstein said.

Conclusion: The fact that photons and neutrinos arrived at Earth simultaneously from a supernova proves that the space they traveled through was curved.

Reasoning: Photons and neutrinos reached Earth at the same time from a distant explosion, which aligns with Einstein's theory of gravity as space curvature.

Analysis: To strengthen this argument, we need to solidify the link between the simultaneous arrival of these particles and the curvature of space. The argument currently assumes that if space were not curved, or if gravity acted as a traditional force rather than a property of space, these two different types of particles might not have arrived at the same time. Look for an answer that confirms that photons and neutrinos would only arrive simultaneously if they were traveling along the same curved 'track' of space. Anything that rules out alternative explanations for their synchronized arrival will also help.
