    Comparing Neutron Bombs vs Nukes: What's the Difference?

    Ok I've done quite some reading on neutron bombs. What exactly is the difference between them in the way they work? The way i see it now its a nuke, but not focused on heat/blast damage but radiation. How does it work? Other material used? And what isn't really clear to me is if they have...

    Observational Difference Between Neutron Star & Black Hole

    What is the observational difference between a neutron star and a black hole? Is the evidence conclusive, or is it based on a strong reasonability argument?

    Why do neutron stars have magnetic fields

    An article by W Tucker and K Tucker at NASA says that neutron stars have magnetic fields. If a magnetic field is created by moving charges, and neutron stars have not net charges to move, how are the fields created?

    Question-can a neutron star shed mass?

    Question--can a neutron star shed mass? Once the steller core of a massive star collapses into a neutron star, is there any known mechanism by which the neutron star can shed mass?

    Formation of Black Holes from Neutron Stars and White Dwarfs

    how is a black hole formed exactly from a neutron star or a white dwarf?? what is it? is it a star? is it defined as a matter?? and what happens when light gets sucked into it? there ought to be an increase in energy in it right? what happens to this energy?

    Neutron stars seem an oddity to me

    neutron stars seem an oddity to me, they seem to have to much mass to size to be held together purly by gravity do neutrons have mutual attraction? or is space very very distorted by them?

    Do Strange Stars and Strange Black Holes Really Exist?

    Do strange stars exist? Apparently they are denser than neutron stars and consist of up down and strange quarks. But are they theory or reality?

    Why don't hydrogen atoms -> neutron + neutrino?

    Hey all, I'm a Theoretical Physics undergrad and so far I've only done one course in QM. Mainly playing with the TISE pushing wavefunctions around. Anyway after some trolling on here I've gotten to wondering, in a hydrogen atom why doesn't the electron just collapse into the nucleus? The...

    Status of neutron magnetic moment?

    I believe to remember some recent comments about the measurement of neutron magnetic moment or some other quantity of this particle, which was not very well in agreement with standard model calculations. I can not remember which measurement it was, or when. Can anyone help my poor neurons?

    How Do You Calculate the Average Density of a Neutron Star?

    Okay, I am told to find the average density of a neutron star with the same mass of the sun but with a radius of only 20km. I figured this would be pretty simple so I just would divide the Sun's mass (found using Google) by the volume of the neutron star which would be (4/3)*pi*r^3 with r being...

    Detecting Neutrons: Simple Methods for Beginners

    Hello all I am new here, please pardon me if I have posted to the wrong board. My question should be fairly simple. I am building a fusor which I am hoping will generate neutrons from a D-D reaction. However, I have no way to detect them:frown: I was wondering if there are simple ways to...

    Were in the neutron is the electron?

    Perhaps the proton is a spheare and the electron is a dot! Is the electron in the middle of the neutron?

    Gravitation, neutron starlooks simple

    A neutron star is formed when a star has burned all its nuclear fuel and begins to collapse in upon itself. It then packs roughly the mass of our Sun into a region with the same radius as that of a small city while continuing to spin at very rapid rate. Let's say you have a neutron star with a...

    Can We Create a Neutron Star in an Earth Lab?

    I heard, somewhere, that an thimble full of a neutron star would weigh on Earth many thousands of elephants. Hmmm... I suppose that this is true. But I wonder this: With all of our advanced technologies, is it possible to form such high density matter, even a thimble full, in an Earth lab?

    Could New Pulsar Discoveries Lead to Direct Detection of Cosmic Gravity Waves?

    4 dec 2003. http://www.physlink.com/News/120403PulsarGravity.cfm A discovery made with CSIRO's Parkes radio telescope in eastern Australia may have brought forward the day when astronomers will directly detect cosmic gravity waves for the first time...

    Why can't a neutron be thought of as a proton plus an electron and neutrino?

    Wow. Clean slate! I like the format! And I've got a question. In elementary physics, it is said that the neutron can "sorta" be thought of as a proton plus an electron together. The mass of the neutron is slightly higher than a proton, by approximately the mass of an electron; in beta...

    Coalescence between a neutron and a K+ meson

    I think it is simply the coalescence between a neutron and a K+ meson. What are your thoughts?

    Neutron energies at which C14 is produced

    Some time back a friend (PhD Nuclear Engineer), told me that the energies a neutron needed to form C14 from nitrogen were (and this is where my memory gets real fuzzy) around 15 MEV. Furthermore that neither nuclear explosions or the Sun produced neutrons of this energy. The implications were...

    Magnetic Fields of Neutron Stars

    It is a known fact that neutron stars and pulsars, remnants of super nova explosions, have very strong magnetic fields. It is said that the collapse of the core amplifies the magnetic field of the progenitor. This is due to the fact that the magnetic fields lines are drawn closer together during...

    Uncovering the Mystery of Neutron Decay and the Origins of the Universe

    If in a beta decay when a neutron decays into a proton,electron,and a anti nutrino,that the answer to where all the particles came from is not answer by this alone?the universe started with just neutrons,then half of them decayed into protons and electrons,and started the universes...
