When the sun sends its neutrinos it's not sending the best. It's sending particles with lots of problems, and they're passing those problems through us. They're bringing faster than light movement, they're bringing new insights in particle physics, they change flavors, and some, I assume are antineutrinos.

Does "not having mass" mean it cannot transmute? When I heard that I thought that being massless it travels at speed of light, therefore its own time is still and that's why it cannot change.

I have been struggling through the neutrino interactions and coming up short. Does the physical cross section of a nucleus have a direct correlation to its barns? (Do barns even count for anything in neutrino interactions?) Is the probability of a neutrino smacking into a nucleus a simple arithmetic problem of the cross section? It seems like it must be FAR less probable than that. My uni classes gave values for barns for thermal and intermediate neutrons, and they did not seem to have any correlation to the size of the nucleus, if a few decades of cobwebs haven't messed with my memory. So if cross section is not the important part that non-quantum thinking makes it seem to be, neutrinos pass through nuclei without noticing them... ? My apologies if this was already covered. I read through a lot of the comments and didn't find it. Thanks for any help to figure this out.

+Seth Hastings We have been able to reach within a billionth of zero degrees Kelvin, which is pretty close. So neutrinos aren't the only reason why that would be impossible. If you were able to construct hypothetically a container that isolates its content from the rest of universe entirely i.e no radiations, no neutrinos, you would still not be able to reach absolute zero. That's because it's just theoretically impossible. And because of multiple reason. I will list one - In Quantum Mechanics, there's a fundamental principle known as Heisenberg Uncertainity principe which places an upper bound on certainity of momentum and position of particle i.e. you cannot precisely determine both the momentum and the position of the particle. This means that increasing your accuracy in measurement of either momentum or position would come at the expense of accuracy of the other. Now consider this, at absolute zero you would have no motion which would mean that you'd know both the position and momentum of the particle precisely. This is in direct violation of Heisenberg's uncertainity principle !

If the increase in neutrinos occurred at the same time as the light hit earth, does that not imply that the neutrinos are travelling at the same speed as the photons, and therefore cannot have mass?

In "What do you care what people think" Feynman tells about how his father asked him if the electron that's emitted by an atom when it changes state was in the atom ahead of time. It's nothing like that. A neutron isn't a container with two physical down quarks and an up quark and a neutrino that falls out when you replace one of the down quarks with an up quark. The quarks are not physical objects. They're properties of the proton, and the neutrino only begins to exist when it's being released.

You probably don't care about a random question you posed 4 years ago, but on the off chance that you do: The answer is that this is a nuclear reaction, it's not something that just happens randomly without prompt. If I had a container with a bunch of protons bouncing around at room temperature, they would never undergo this transformation. I have to input a huge amount of energy (heat and pressure) in order to force this reaction to occur. And by adding that energy to the system you account for the missing mass in the equation via E=mc². The sun, whose core temperature is ~14 million degrees Celcius has an abundance of energy to go around and account for this "extra" mass.

As long as the neutrinos have mass, they have forces of attraction which interact with other masses. They do get affected, but the effects are very small, almost negligible. So there is no reason why Black holes wouldn't affect them (even an atom in our body does). This is the relationship between Gravity and Mass and Distance.

That's a good question. Considering the distance between Earth and a supernova, light vs. neutrinos would travel a significant enough distance to reveal the difference between their speeds. If neutrinos indeed travel slightly faster than light, then we should have observed the spike in neutrinos about an house or so prior to seeing the supernova. I suspect the scientists are going back to these observations if the spike arrived hours before visual observation of the supernova.

The short version of e=mc2 is that energy and matter are 2 sides of the same coin. Just like there is no electricity without magnetism (elctromagnetism), just like there is no space without time (spacetime), there is no energy without mass (I guess it really should be called energymass). We should still remember that the theory of relativity predicts it's own downfall when spacetime is so strong it's bent into a singularity, so whatever theories we have are, by definition, limited and tentative

I just thought of something and it may seem completely worthless but i could be right. maybe when the nuetrinos were going faster than light something happened to give them a negative mass or maybe they went through a negative area of space

@djfxtrader900 Not quite, there were also trace ammounts of heavier elements, mostly lithium.

What's the speed of neutrinos? Did one measure the or any delay in time compaired with the fotons from that super nova explosion? No delay should mean neutrinos have no mass at all. If there is a mass, how ever small; The total amount of energy neutrinos represent must be enormous.

@skinnyjohnsen I think it would be hard to know what neutrinos came from the supernova and what came from earth, since they are so hard to detect. I remember watchin a documentary about the first experiment, where they had that large pool of chlorine(mentioned in this video), according to calculations they should have detected about 10 neutrinos per week, and they only detected 3 neutrinos on average... thats because they only could detect one type back then, they didn't know of the other two.
