Perhaps the physical processes are also completely different? “Basically we do not know what really happens – at least we have now learned what does not happen there.” Read more:

Today I read an article that gives quite some interesting information about neutrinos.

But this article also reminds one of the messages coming via Bertha Dudde and reporting about the radiation coming from God which goes through everything and which we can use when we consciously make use of it.

But this article also cast doubts on the sun, our sun, and also other suns, being the origin of neutrinos. It also casts doubts on the heat coming from the sun as being produced inside the sun.

Here now some extracts from the article I read today:

 

For a long time gamma lightnings were regarded as probable source of energy rich cosmic radiation. Latest measurements with the neutrino telescope “Ice Cube” cast doubts on it now.

Always trouble with the neutrinos.

Now neutrinos turn a current model for the origin of the cosmic radiation upside down. With the neutrino telescope “Ice Cube” at the South Pole an international group of researchers has looked for two years for energy rich neutrinos from so-called gamma ray eruptions, the gamma ray bursts – in vain. Between 2008 and 2010 not one single particle went into the net.

The gamma ray eruptions were until now regarded as hot candidates for “cosmic super accelerators” and therefore as original locations of energy rich particle radiation, which bombard our planet unceasingly.

The origin of these energy rich particles is still mysterious although the cosmic radiation was already discovered hundred years ago.

As cosmic particle catapults, gamma ray eruptions were supposed to send out neutrinos en masse and these were supposed to arrive with the gamma radiation on earth at the same time. Neutrinos would come into being when the accelerated hydrogen nuclei collide with light particles. While the electric loaded nuclei are forced onto confused courses through galactic magnetic fields, the unloaded neutrinos reach earth on direct ways and therefore point to the location of their origin.

The researchers of IceCube investigated more than three hundred such gamma lightnings: “Always then, when a gamma lightning appears in the sky, its position and the time of the explosion is recorded by satellites” explains Christopher Wiebusch of the RWTH Aachen, co-author of the published study in the magazine “Nature” (Volume 484, page 351). “With our detector we check in the recorded data in this time whether we have registered a neutrino, which came from the direction of the gamma eruption.” Most of the time this is not the case, because almost all of these fleeting neutrinos cross the earth, without leaving any tracks. Nevertheless Wiebusch and his colleagues would have expected about eight neutrinos out of all the investigated gamma lighnings. Though the scientists have seen nothing.

So are gamma lightnings therefore still not the looked for super accelerators of the cosmic radiation? Wiebusch thinks this to be likely.

Perhaps the physical processes are also completely different? “Basically we do not know what really happens – at least we have now learned what does not happen there”, thinks Wiebusch.

Because neutrinos themselves can fly through the entire earth unhindered, IceCube has a quite large extension.

These atmospheric myons rain from above onto the ice. On the other hand myons can also come from “below”, therefore from the direction of the interior of the earth, and exactly in these the physicists are interested, since they could have been produced by neutrinos only. When several domes are registering the tracer of the myons at the same time, then the line of flight of the myons and with it the direction of the origin of the original neutrino can be determined. About hundred thousand neutrinos the equipment detects each year on average. Up to now these seem to originate from completely arbitrary directions, no clear source could be determined in the sky till now.

“Fifteen years ago we dreamt about finding the cosmic radiation source with a hundred times smaller detector than IceCube”, tells Wiebusch.

In any case the high energy neutrino astronomy has produced its first important astrophysical result. It is to be expected that the young research discipline has further surprises in store. The IceCube telescope, which was completed at the end of 2010, is supposed to look for cosmic neutrinos for more than ten years. When the results furthermore call the foundations of their theoretical models into question, it will mean for the astrophysicists more often: back to the drawing board.
