Support Recently, photons and neutrinos emitted by a distant supernova, an explosion of a star, reached Earth at virtually the same time. ████ ███████ ████████ ██████████ █████ ████ ███████ ██ █ ████████ ██ █████ ███████ ██ ███ █████ ████ █ ████ ██████ █████████████ ████ ██ ███████ ███ █████ ██████ ███ ███ ████████████ ███████ ██ ███ ███████ ███ █████████ ██ ████████ ████ ███ █████ ███████ █████ ████ ████████ ███ ███████
Summarize Argument
The author concludes that the simultaneous arrival of the photons and neutrinos supports the claim that gravity is a property of space itself. Specifically, it is evidence that bodies exert gravitational pull by curving space.
Notable Assumptions
The author assumes that we can't expect neutrinos and photons to have reached Earth at the same time unless space was curved. In other words, if space were not curved, we would expect protons and neutrinos to arrive at different times.
