Because gravity overcomes electron degeneracy pressure and the electrons are forced into the nuclei. When the electrons enter the nucleus they merge with the protons emitting neutrinos. The nuclei then merge leaving a neutron star held up by neutron degeneracy pressure or gravity makes it collapse to a black hole.

∙ 13y agoYes, our sun is producing nowadays the recommended amount of neutrinos which are stablished by "The Sun Manager on Basic and Vital Solar Components" ( TSMFBVSC) In the case of an unexpected modification I will warn you through my blog . http:sidmelo.blogspot.com. (Have a peaceful night))

What can penetrate the sun?
Neutrinos.
What does the sun turn into helium?
If you are asking "how helium formed the sun?" then for your information, sun and all the stars are formed mostly from Hydrogen. And if you are asking "How helium is formed in the sun?", the answer is that the Hydrogen in the sun fuses in itself(that's where from the sun get's its energy and luminosity) producing variety of elements like helium, carbon oxygen,iron etc.
What does the core of the sun do?
The innermost layer of the sun is the core. With a density of 160 g/cm^3, 10 times that of lead, the core might be expected to be solid. However, the core's temperature of 15 million kelvins (27 million degrees Fahrenheit) keeps it in a gaseous state. In the core, fusion reactions produce energy in the form of gamma rays and neutrinos. Gamma rays are photons with high energy and high frequency. The gamma rays are absorbed and re-emitted by many atoms on their journey from the envelope to the outside of the sun. When the gamma rays leave atoms, their average energy is reduced. However, the first law of thermodynamics (which states that energy can neither be created nor be destroyed) plays a role and the number of photons increases. Each high-energy gamma ray that leaves the solar envelope will eventually become a thousand low-energy photons. The neutrinos are extremely nonreactive. To stop a typical neutrino, one would have to send it through a light-year of lead! Several experiments are being performed to measure the neutrino output from the sun. Chemicals containing elements with which neutrinos react are put in large pools in mines, and the neutrinos' passage through the pools can be measured by the rare changes they cause in the nuclei in the pools. For example, perchloroethane contains some isotopes of chlorine with 37 particles in the nucleus (17 protons, 20 neutrons). These Cl-37 molecules can take in neutrinos and become radioactive Ar-37 (18 protons, 19 neutrons). From the amount of argon present, the number of neutrinos can be calculated.
When is our sun expected to blow up?
Our sun is expected to expand into a red giant in 5 billion years which will swallow the earth
Which object is capable of producing its own light?
The sun is capable of producing its own light.
What is a solar neutrinos?
Solar neutrinos are electron neutrinos that are in the sun. The sun is what produces nuclear fusion.
Explanation of missing solar neutrinos?
Neutrinos are incredibly hard to detect so the "absence" of neutrinos doesn't mean they are not there. It was long thought that neutrinos did not decay. We now know they do so. Thus, the lower than expected number of neutrinos detected coming from the Sun has been fully explained. It took four decades but the problem is now fully resolved.
What can penetrate the sun?
Neutrinos.
Can neutrinos change into other types of neutrinos?
Yes; the scienific terminology for this phenomenon is "neutrino oscillation". Neutrinos exist in three different flavours - electron, muon and tao neutrinos, listed in order of increasing mass (each also has an antiparticle). Although it is not know why this is the case, it was originally discovered that neutrinos oscillate when examining the neutrinos emitted by the sun; although primarily electron neutrinos are emitted as a result of the fusion process within the sun, the quantities of the different flavours of neutrinos detected on Earth from the sun are in roughly equal proportions.
What part of the Sun do neutrinos originate?
The core.
How do measurements of neutrinos from the sun pose a problem for modern astronomy?
At present, no problems. 15 years ago, scientists had no explanation for the small number of solar neutrinos detected at our Earth. Either we didn't understand neutrino formation in our Sun, our detectors were wrong, or neutrinos had the capacity to decay. The latter seemed to be the least likely possibility, so scientists argued for many years which of the first two was correct. In 1998 it was discovered that neutrinos do, indeed, decay into other neutrinos. The reason we weren't seeing as many neutrinos as we expected was because the ones we were expecting to see had decayed into other types. So the solar neutrino problem is no longer a problem.
Astronomers are interested in solar neutrinos because neutrinos carry with them information about?
The nuclear reactions going on in the heart of the Sun.
What does a neutrinos do?
Neutrinos are elementary particles that travel close to the speed of light, lack an electric charge, are able to pass through ordinary matter almost undisturbed and are thus extremely difficult to detect. Neutrinos have a minuscule, but non-zero, mass that was too small to be measured as of 2007.
What particle do you detect coming directly from the solar interior?
Neutrinos come from the sun's core.
What are three emissions?
The answer will depend on emissions from what? The sun, for example, emits light, uv rays and neutrinos.
How can neutrino oscillation explain the solar neutrino problem?
The solar neutrino problem relates to the discrepancy between the proportions of the different flavours of neutrinos emitted by the sun in the theoretical model as opposed to experimental measurements. Whilst the sun primarily emitts electron neutrinos, neutrino observatories such as SNO+ detected neutrinos in roughly equal proportions of the three flavours; furthermore the quantity of electron neutrinos detected was less than the theoretically predicted value. Both of these can be explained by neutrino oscillation - in which the neutrinos alter their mass to change their flavour (ie. an electron neutrinos gain mass to change to a muon neutrino). This would also explain the relative lack of electron neutrinos, thus solving the solar neutrino problem!
How was the Solar neutrino problem solved?
The problem was that the Sun should output a lot more electron neutrinos then were measured. This meant that the model describing the interior of the Sun would be wrong, but it was working very well in predicting other things. It was finally solved when something called neutrino oscillation was discovered. It turned out that (this might be a bit technical) the interaction state of a neutrino was not equal to its mass or propagation state. In short, this meant that electron neutrino's could become muon or tau neutrino's after a while (and change back again after that). After this people began looking for muon and tau neutrinos coming from the Sun and together with the electron neutrino number they added up to the amount the Solar model predicted. The problem was thus solved; the Sun DOES output more electron neutrino's but some of these change into muon or tau neutrinos before they reach the Earth, and since we were initially only looking for electron neutrinos we missed some.
