Recently, photons and neutrinos emitted by a distant supernova, an explosion of a star, reached Earth at virtually the same time. This finding supports Einstein’s claim that gravity is a property of space itself, in the sense that a body exerts gravitational pull by curving the space around it. The simultaneous arrival of the photons and neutrinos is evidence that the space through which they traveled was curved.

Summarize Argument: Phenomenon-Hypothesis

The author concludes that gravity is a property of space itself. Her evidence is that photons and neutrinos emitted by a distant supernova all reached Earth at the same time.

Notable Assumptions

The author believes that the neutrinos and photons wouldn’t have all reached Earth at the same time unless gravity was a property of space itself. The author therefore assumes that objects moving at uniform speed through space signifies that gravity is a property of space.

Einstein predicted that photons and neutrinos emitted by any one supernova would reach Earth simultaneously.

We don’t care if Einstein predicted the premise. We’re trying to strengthen the connection between that premise and the conclusion: that gravity is an aspect of space.

If gravity is not a property of space itself, then photons and neutrinos emitted simultaneously by a distant event will reach Earth at different times.

Unless gravity was a property of space, then the photons and neutrinos would’ve reached Earth at different times. Since they reached Earth at the same time, gravity must be a property of space.

Photons and neutrinos emitted by distant events would be undetectable on Earth if Einstein’s claim that gravity is a property of space itself were correct.

We don’t care about whether photons and neutrinos are undetectable. Besides, those photons and neutrinos evidently were detectable, yet the author argues Einstein’s claim is correct.

Photons and neutrinos were the only kinds of particles that reached Earth from the supernova.

We don’t care. There could’ve been other particles the author chose not to mention.

Prior to the simultaneous arrival of photons and neutrinos from the supernova, there was no empirical evidence for Einstein’s claim that gravity is a property of space itself.

We don’t care when Einstein’s claim was given empirical weight. We’re trying to strengthen the connection between the particles reaching Earth at the same time and gravity being a property of space.
