Why neutrons are very unstable when they are alone? Neutrons are very stable, when they are in the nuclear with protons. Proton , electron and neutrino etc. are not dependent on there position. Muon is independent on their position, always very unstable.

Can we never make below 0K?
alpha2cen replied to alpha2cen's topic in Modern and Theoretical Physics
Instrument temperature of the infrared space telescope is 0.1K. So 0K is very cold. There is no problem using coolant medium. I don't know 0K problem. 0K scale region is very large? Below 0K is out of atom area in the Universe? -
Can we never make below 0K?
alpha2cen replied to alpha2cen's topic in Modern and Theoretical Physics
Normal matter has no fluid behavior at 0K. But unknown matter which dose not interact with normal matter would have any fluid behavior. If so, we can use this property to search for Dark Matter. This is another idea to search Dark Matter. One required condition is proper Dark Matter concentration. -
Anti-hydrogen capturing is all done. So next research area is anti deuterium capturing. But neutron handling is not easy. And then anti-neutron, how to separate it? Neutron and anti-neutron separation is very difficult problem. Before annihilation occurring they should be separated. Which method? Any physical difference which we can separate them? Directly anti-deuterium making is reasonable. We first make anti-deuterium mixture, and separate it.

How to make near 0K? Is it possible to remove the heat without more lower temperature? " uncontrolled parameter " means any entropy whch exists at 0K, not molecular or electrical. But it is required to be 0K, its more basic entropy like particle wave. -

alpha2cen replied to alpha2cen's topic in Modern and Theoretical Physics
So the negative temperature is made by controlling the uncontrolled physical parameter existed 0K. It's not the common heat capacity which is related to the molecular motion(vibration, rotation, ...). http://www.newscient...olute-zero.html from Cap'n Refsmmat. This is one of uncontrolled parameter control. -
Atom has slightly more mass than it protons+neutrons?
alpha2cen replied to netrat's topic in Quantum Theory
It's very difficult question. 'more tightly bound system' How it is related to mass loss? Till now we don't know how to get mass in the particle system. One of objects of present LHC experiment is to solve this question. Fusion result , more tight nuclear structure is well known, but detail mechanism of mass loss is another problem. -

alpha2cen replied to netrat's topic in Quantum Theory
It's important question. I've thought about it till one year. p n(deuterium) +p n(deuterium)---------------->p2 n2(helium) .............................................missing mass The missing mass, where did the missing mass go? The theory say it turns into the energy. How to turn into mass----> energy? No one know the answer. I'm afraid of saying but its the key of the mass getting step, my guess. -

alpha2cen replied to alpha2cen's topic in Modern and Theoretical Physics
Then we have to modify the 3rd law. If negative temperature were existence, this equation would be correct. Same material , no latent heat between two temperatures. -5 K , 1g + 5 K , 1g -----> 0 K , 2g How to define negative scale? -
Present we never make below 0K. And Thermodynamic law tells us there is no degree below 0K. Why we do not make below 0K? Are there any materials below zero? For example unknown matter. We say it Dark-matter. Are there any possibilities below 0K Dark Matter existence? It's freely moving below 0K.

It's related to stellar stability. Stellar is a big object. When nuclear reaction happens in the stellar, huge amount of mass and energy transfer is required. In order to reaction proceeds smoothly without big unbalance, certain harmony is required. **mass input -----------------------------> reaction ----------------> product (plasma ion, high molecules, neutrino...) **fluid transfer.......heat emission(gamma way emission..).....electromagnetic balance.......gravity That is the stellar sound or the stellar music. If it did not exist, stellar behavior would be very irregular. When the star becomes more bigger and bigger , the big size breaks the harmony or increases the wave period and wave intensity - my assumption.

Its conditionally correct. if mg-ma = g-a , m should be 1, 0 if m=1 (mg-ma)/g =(g-a)/g =1 -a/g if m=0 g-a =0 (mg-ma)g= 0/g = g-a/g = 1- a/g a = g, not 0
-
This explanation is reasonable to explain reaction condition before explosion. n particle + m particle -------- >p particle + q antiparticle q particle + q antiparticle -----> energy This reaction can be occurred in the particle accelerator. If it consisted of the matter-antimatter chain reactions, it would be more powerful than common nuclear reaction. To prove this, any gamma wave or mass loss data which represent before and after reaction is required. Particle-particle fusion concept.

Important thing is how to make more massive point. If iron atom is existed, it would be existed homogeneously in the star atom existing area. The more massive point is made of repeatedly contract and expand. Is the core same as less massive star in the supernova? It is not well known. But I think the core is more dense than less massive star. When explosion happen,the nuclear reaction is not common proton - neutron reaction. It wold be quark related fusion-my assuming. Which one makes repeatedly contract and expand? Resonance, which is its own sound meet with the stellar size. Or gravity wave from other space -assumption.
-
Assumption Stellar resonance phenomena? If star is more bigger, it causes a big stellar wave resonance phenomena . Its not proved yet. But, Some papers recently published said the Sun has its own sound. Similarly stellar has its own sound. When its own sound meet with the stellar size , it would repeatedly contract and expand. At sometime it could be very contracted, its energy state is beyond common nuclear reaction. It will explode. The other possibility is the resonance phenomena of the gravity waves and big stellar size. This could make very big contraction. Gravity waves comes from other space region.

I'm afraid, but how about this paper. Something strange. http://ia64.phys.iit.edu/OCS/index.php/PSAPS-CSAAPT/2010/paper/view/7

About explosion. The speed is too fast. I think inside the stellar every particles are plasma state, or free particle state( assumption). Think about the state before explosion. If gravity is enough, the fusion reaction occur. The heat would be released into light or ionized photon .... The heat release is not no problem, because gravity is so high not to escape high energy particles or electro magnetic waves. Supernova explosion procedure (assumption) In the supernova some causes makes very high density core condition. ---->The core attract surround matter. ---->The core become more dense. ---->The reaction condition is over the common nuclear reaction. Gravity broken phenomena ------> other state (anti-gravity, assumption) ---->explosion happen.

I,m interested in supernova. Supernova explosion is well known. Why it should have to be exploded? There are many steps, but it can be simply explained like this. One star -----> mass loss ---->gravity decrease ------> supernova ------>explosion. What I don' t understand well is gravity decrease and supernova explosion phenomena. If gravity decreased, the nuclear reaction rate would decrease, and inside star energy would be decreased. There is no reason it should have to be bigger. Are there any unknown star phase exist?
-
It could be created by atomic collision. For example, antiproton is like this. P+------------>2P+ + P- The collide reaction is required very high energy particles. After collision separaton and colling process is needed. All of them are very expensive process. Another sources are in the space. High energy cosmic ray collision makes antiparticles.

Has CMBR not been affected by Universe expansion? Are middle ages CMBR and present CMBR same waves? For example middle ages Universe CMBR----------------------> Present CMBR very short wave..............................................> long micro wave? When we throw a stone in the circular pond, at first the water wave length is short, but time pass by the water wave length will be longer and longer .
-
I've heard many things about antiproton. The key point is how to make it more cheaply and less energy consumming. Present method is very expensive. We can use it for treating cancer. But its very expensive. Its good for treating deeply buried tumer. It gives no damage to the surface tissue.

When we were at the outside of the Galaxy, Could we see same CMB picture? We see the cosmos in the heliosphere, and outside of the solar system, there are interstellar clouds. Are we able to see the CMB, as if we were far away from the Galaxy?

Proton has one more up quark, and neutron has one more down quark. But the difference is very big. Are there any potential energy equations which describe elementary particle behavior? Perhaps protons have very low potential energy.
