Single neutron decay rate is constant?

[alpha2cen]

According to the accelerated expansion theory, in the future the Universe will move more faster than now. At that time our atom stability is the same as the present one? At present, if we test single neutron decay rate at the high speed, how will be the decay rate? Will the rate became fast or slow?

What high speed? We are in a rest frame. We won't see any change in neutron decay rates.

[alpha2cen]

Does the distance/time from the center change when the balloon volume is increasing ?

Is the cooled neutron decay rate the same as the fast moving it? Does cooled neutron decay more fast than fast moving one?

[alpha2cen]

Recent data says fast moving neutron life time is long, and the standard deviation of the fast moving neutron is large than slow moving one.

The standard deviation is caused by earth movement effect around the Sun plus the Galaxy rotation?

More exact knowledge will be obtained from the model calculation and experiment data fitting .

Perhaps one technique is simply more precise than the other? If there was a difference due to motion, you would expect a different value for the decay. How much change you you expect there to be?

Standard deviation of the lifetime might be key factor.

Let's think about this case, neutron speed is not so high than earth movement.

If neutron speed is high, standard deviation value will be high. If not, standard deviation value will be low.

Two methods are low speed decay method. Storage technique seems like a little more slow speed than beam technique.

It seems like absence to do an experiment to measure neutron lifetime with it's velocity.

Does the fast rotation of a particle or a object cause a time dilation? For example neutron star. Neutron star has high gravity and fast rotation.

Time dilation causes a bias, not an increase in the error.

Neutrons in a neutron star don't decay. That's why it's a neutron star.

 

In general, rotation in a gravitational system doesn't cause time dilation, because it is compensated for by a deformation, causing a difference in the gravitational time dilation. The effects cancel on the equipotential surface.

How about looking at this figure?

Fast neutron speed make errors.

Neutron speed can be increased or decreased.

So is there any data that supports a direction-based change in decay? That the rate is different in January as opposed to June? How much of a difference should there be, according to your hypothesis?

[alpha2cen]

Because of the earth rotation, the data change would be irregular. The moving direction of the neutron might be changed every hour. The position of the instrument(latitude) on the Earth and neutron moving direction might influence on the direction change. Earth revolution effect around the Sun is within +- 12% of the Galaxy rotation.

The rotation speed (0.5 km/s max) is smaller than the revolution speed (30 km/s). The neutrons held in traps should have an annual fluctuation, depending where we are in our orbit. Do we see this?

If we have neutron speed data in the instrument, we will estimate more exactly about the phenomena.

How much of an effect do you expect to see?

I do not know the value. But, if neutron velocity is about 500~ 5000 km/sec, we will see the fluctuation of the decay rate. In the case of 5000km/sec, the fluctuation will be very high. But, below 500km/sec the fluctuation will not be so high. Detail calculation is required.

5000 km/s gives a gamma of 1.00014. The dilation of the lifetime of a neutron at that speed would be about a tenth of a second. That's not a very large fluctuation compared to the experimental error or difference between experiments.

Thank you for good calculation.

 

Possible speed is like this.

Galaxy rotation speed x 2 x100(1% speed variation)= 50000km/s

Actually the speed can be used in the neutron process??

[alpha2cen]

If the Universe were not expansion, particles life time would not be so long. In that situation, our human being might be no existence?
