Massive objects, such as the Sun, do deflect the paths of neutrinos due to their mass, as established by general relativity. This principle, demonstrated in Einstein's 1919 experiment, applies universally to all massive particles, including neutrinos, which possess nonzero rest mass. While neutrinos travel at speeds very close to that of light, their trajectories are still influenced by the gravitational fields of massive objects. Therefore, the deflection of neutrinos by gravity is a fundamental property of spacetime.
PREREQUISITESPhysicists, astrophysicists, and students interested in particle physics and the effects of gravity on subatomic particles.
Don't Neutrinos have nonzero rest mass and still travel at lightspeed? Could this possibly give them the inertia needed to continue in a straight line, piercing stars and galaxies unbent as well as unslowed?Orodruin said:Yes. Why would neutrinos be any different from any other massive particle in this regard?
To your question, general relativity tells us that mass bends space-time. So light and neutrinos are deflected by massive objects.HeavyWater said:Summary: Do massive objects deflect the trajectories of neutrinos?
