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.

Neutrinos.
What forms when he sun fuses hydrogen?
When the Sun fuses hydrogen in its core, it primarily converts hydrogen into helium through a process called nuclear fusion. This reaction releases a tremendous amount of energy in the form of light and heat, which powers the Sun and emits the sunlight we experience on Earth. Additionally, this process produces neutrinos and other particles, contributing to the Sun's overall energy output.
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.
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.
Why does the sun emit neutrinos?
The sun emits neutrinos as a byproduct of nuclear fusion reactions happening in its core. These reactions produce high-energy particles, including neutrinos, which are released into space.
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.
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.
What part of the Sun do neutrinos originate?
The core.
Astronomers are interested in solar neutrinos because neutrinos carry with them information about?
The nuclear reactions going on in the heart of the Sun.
Do solar neutrinos observed on Earth come from the hot spots in the corona?
No, solar neutrinos observed on Earth primarily originate from nuclear fusion processes occurring in the core of the Sun, not from the hot spots in the corona. These neutrinos are produced when hydrogen nuclei fuse to form helium, releasing energy in the form of neutrinos that escape the Sun's dense core and travel through space. While the corona does emit various forms of radiation, it is not a significant source of neutrinos.
Why do photons take so much longer than neutrinos to emerge from the sun?
Photons take longer to emerge from the sun compared to neutrinos because they interact more frequently with the sun's dense matter, causing them to be absorbed and re-emitted multiple times before finally escaping. Neutrinos, on the other hand, hardly interact with matter and can easily pass through the sun, allowing them to emerge much faster.
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 is the origin of neutrinos and where do neutrinos come from?
Neutrinos are subatomic particles that were created during the Big Bang, the event that started the universe. They are also produced in nuclear reactions, such as those that occur in the sun and other stars. Neutrinos can also be generated in high-energy processes, like those that happen in supernovae and particle accelerators.
