We know hydrogen atom is stable. Then, single proton is stable? Can we store it for a long time without decay? Do we have any related equation about particle stability?

Sorry, I only think fast moving increases the collision frequency per time. But, standstill collision frequency is too low.

One of the fast moving icy objects is Saturn's moon Enceladus. I am curious , it's polar region water vapor eruption. Some researchers say "it's electromagnetic phenomena". But it's eruption speed is too high. The water is erupted from the deep underground.

To make tail, sufficient energy must be supplied for evaporation or sublimation. The source of the energy, we think, is solar radiation energy, solar ion enrgy . But, we are far away from the sun. The energy is very low.

Have we never seen a comet which has a tail far away from the sun?

How we think about detection it in the underground instrument? Might we believe this rule(time × measurable DM colliding frequency with the instrument )? If this rule is suitable, comet would also collide with measurable DM.

If there is Dark Matter in the solar system, the erosion of comet with Dark Matter will be happen? A comet's main component is water, water has many nucleus per unit volume. and comet speed is very high. So. comet has high collision frequency with Dark Matter per time. Total energy for the...

Higgs field can explain time dilation near light speed C? It is Relativity theory area?

It would be very difficult optimization problem. First we must know the reactor condition exactly. If we can control the reactor temperature, cease radio active material emission and maintain safely the vessel long, we do not have to demolish the reactor so fast. But If we can not control the...

One of the problems at this nuclear plant disaster is that we did not know the exact situation after earthquake and tsunami attack. If we knew the exact condition about the nuclear plant, the worst disaster would not happen. Why we did not do proper action at that time? Someone say there was...

What is important at this point? I think to obtain the more detail and accurate information about the destroyed power plant is important. It will bring more wise solutions.

One of the problems at the Fukushima nuclear accident is we did not know reactor conditions well after the earthquake and tsunami attack. We think about reactor measuring system again. We have to make the measuring instruments of the very important parts of nuclear plant as dual system. One is...

How about making small RTG(radioactive thermoelectric generator) assembled nuclear power plant? First make small RTGs in the battery plant, and power station only assemble them. And used battery is retreated, and use it again. At the present high voltage technology is not developed, but we...

But at the point of nuclear reactor control, Is this conclusion always right? Is the time lag of PWR model more short than BWR model? Is the response time of the BWR model short?

Is this reaction equation perfectly matched experimental results? high energy ------->N proton + N anti-proton or high energy ------->N quark + N anti-quark i.e., Has the same moles of proton(or quark) and anti-proton(or anti-quark) production been already proved experimentally?
