Other than mass what does a Neutron provide to the Universe?
As evan_au indicates, the neutron plays a formidable role in the universe. The strong force between nucleons (the neutron is a nucleon as is the proton) holds the nucleus together. Otherwise they would decay quite quickly.You should keep in mind that any particular particle need not provide anything to the universe. They're just there, doing their thing!
The Neutron is absolutely critical to Nuclear binding - two protons repel without a neutron.

The Neutron is absolutely critical to Nuclear binding - two protons repel without a neutron. Except in the case of hydrogen and Helium there needs to be at least as many Neutrons as protons to form a stable nucleus. A plot of Z (# of Protons) vs N (number of neutrons) for stable elements diverges from the straight line N = Z The heavier the nucleus, the greater the divergence. For the light elements, the most stable configurations tend to have equal numbers of protons and neutrons
what's the strong force up to? How does a neutron stabilize the nucleus?
Quote from: jcccwhat's the strong force up to? How does a neutron stabilize the nucleus?Both the proton & neutron feel the strong nuclear force of attraction. So a proton and a neutron together (Hydrogen 2 = deuterium) is stable.However, protons also have a positive charge. Two protons repel each other strongly. So a proton and another proton together (Helium 2) is extremely unstable, ie the energy tied up in the electrostatic repulsion is so great that it overcomes the energy involved in the strong nuclear attraction.If you have two protons and a neutron, the neutron adds some attraction from the strong nuclear force, without adding to the electrostatic repulsion, so Helium 3 is stable.In general, it takes slightly more neutrons than protons to make a stable nucleus (this effect is more obvious for nuclei the size of Carbon and larger, where carbon 12 & 13 are stable; carbon 14 is moderately stable, with a half-life in the thousands of years).
if there is a strong force holding protons together, why need neutrons for?
proton carries +1, neutron carries 0, how they attract each other? gravity?
what's the mechanism/source of strong force?
Pete, thank you.i know all those, everyone can wiki knows all those.your answers are not clear enough, what's the source of strong force?what's the nature and mechanism?what's the prove?why strong force only exist within nucleus? is it em force?thank you again!

your answers are not clear enough, ..
what's the source of strong force?
why strong force only exist within nucleus? is it em force?
if i am that lazy, who debunked big bang theory?
do you still think big bang theory is correct?
if i can find answers from wiki, i will not need any help! please agree with me on this.
: a situation in which someone or something must do or have something: something that a person must have : something that is needed in order to live or succeed or be happy: a strong feeling that you must have or do something
I have the very na´ve view that the neutron is a proton that somehow has an electron forced into it that only survives when it has proton companions otherwise ejects the electron after 15 minutes or so.
PS if it all began as a soup of quarks where did the electrons come from that are apparently not built from quarks but a different type of particle ?
Because mesons are massless particles the [strong nuclear] force is short range
Hi... I saw this in a post above:Quote from: PmbPhyBecause mesons are massless particles the [strong nuclear] force is short rangePlease explain - I thought "Because photons are massless the electromagnetic force is long range"?Wikipedia says meson mass is ≥ 139 MeV/c2.So it must be a typo: "because mesons are massive particles the [strong nuclear] force is short range"?
