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?
Neutrinos and photons are both fundamental particles in the Standard Model of particle physics. Neutrinos are electrically neutral, weakly interacting particles that have a very small mass. Photons are massless particles that carry electromagnetic radiation.
Neutrinos and photons both have properties of waves and particles. They are both electrically neutral and can travel at the speed of light. They also have very little interaction with matter, making them difficult to detect.
The main difference between neutrinos and photons is their mass. Neutrinos have a very small mass, while photons are massless. Neutrinos also have weak interactions with matter, while photons have strong interactions with charged particles.
Neutrinos are detected using large detectors that are shielded from other particles. When a neutrino interacts with the detector, it produces a small amount of light or heat that can be detected. Photons are detected using instruments such as telescopes or cameras that are sensitive to electromagnetic radiation.
Studying neutrinos and photons can help us better understand the fundamental laws of physics and the origins of the universe. It can also have practical applications, such as in medical imaging and energy production. Neutrinos can also be used to study the interior of stars and other celestial objects.
