NASA plans to send a probe that will examine the Sun from a distance of 7 million km and try to decipher two mysterious phenomena related to the Sun
Yoram Ored and Idan Faivish, Galileo
For over 400 years, the closest star to us has been studied from too far away, much to the heart of the scientists. And here, for the first time, NASA plans to send a probe that will examine the sun and various parameters related to it from a much smaller distance.
During its mission, the probe will make a series of approaches, in which it will repeatedly dive towards the sun and come back and move away from it. At its closest approach, the spacecraft will reach a distance of 7 million kilometers from the Sun. This distance is equal to only about ten solar radii (the average radius of the sun is about 700 thousand kilometers). At such a distance, the angular size of the Sun will be 23 times greater and its brightness 500 times higher compared to its image observed from Earth. What they will see from there, it turns out, is not seen from here today.
Investigate mysterious phenomena
The mission, called the Solar Probe Plus probe, is currently in its infancy, and is planned to launch in 2015 and end after about seven years of activity. The spacecraft will try to decipher two mysterious phenomena, for which no explanation has yet been found: one is the very high temperature phenomenon of the corona, the upper layer of the sun's atmosphere.
The temperature of the photosphere, which is the surface layer of the Sun, is about 6,000 degrees Celsius. The simple logic says that as we move away from this layer to the outside, the temperature will drop. Surprisingly, the opposite is happening, and the temperature is actually increasing until at Atara it reaches more than a million degrees Celsius. Although more than sixty years have passed since researchers first noticed this phenomenon, a full explanation has not yet been found.
The second mysterious phenomenon that the spacecraft will try to explain is the inexplicable acceleration of solar wind particles. The solar wind is a stream of charged particles emitted from the sun. The speed of the particles reaches more than 400 km per second. Surprisingly, there is no trace of the existence of a solar wind near the sun itself. Between the sun and the region where the flux of particles that make up the solar wind is distinguished, there probably exists some mediating factor that causes the acceleration of the particles, but so far it has not been discovered. As mentioned, the Shamshit Plus probe will try to trace this factor.
Researchers suspect that many of the dangerous particles created during solar storms get their energy in the corona. The probe will attempt to observe the actual energy delivery process, thus allowing researchers to predict events in which particles will be emitted that endanger the health and safety of astronauts.
Help from Venus
The spacecraft's energy source will, of course, be the sun itself. The spacecraft will be equipped with liquid-cooled solar cells, which will provide it with the electrical energy it will need to operate its devices.
In its dives towards the sun, the probe Shamshit Plus will assist the planet Venus. After each dive, it will return to near Venus and then return and retrace its steps towards the Sun. In this way, an additional gain will be achieved - getting closer to Venus, which will allow observation of it as well.
In an interview with "Galileo" editor Idan Fevish, Prof. Leon Ofman from the Catholic University of America and NASA's Goddard Space Flight Center in Maryland said: "During the probe's mission, the cosmic dust near the Sun will be monitored, which is probably part of composed of the same materials from which the solar system was formed." When asked about the dangers expected for the probe during its mission, he replied: "There is a danger from powerful sun flares in the field of X-radiation and massive particle emissions from the sun's mantle - these may directly damage the equipment located beyond the shielding layer."
Regarding the new insights that may emerge during the mission, Hoffman said: "The main insights will be regarding the flow of energy to the crown. On top of that, the study of the composition of the cosmic dust around it, may shed light on the solar system from the dawn of its formation."

It is quite amazing that until today no technology has been developed that will utilize more energy from the sun's energy, than is currently done with the help of the technology of photovoltaic cells.
Today I think that the utilization is 5-7% of the energy and it is surprising that there is no significant practical progress in this matter.

In Danny Sanderson's book "Public Snoring" such word play appears but in a more sophisticated form.
I am only quoting from memory and not from the text, but there it is told about a giant who was so big that in his steps he stepped on entire settlements and at a certain moment - and this is the point - it is written that "he stepped on the narrow that is forward and backward"

In my opinion, even if there is no other Sabdarmish Judas in the universe, there is one anti-Sabdarmish Judas, with the opposite charge of yours. He certainly favors the existence of dark matter and the existence of black holes.
I searched in 144 and there, at least, there is none.
Since a person who doesn't have a phone is not considered and since I checked all over the country and not just in the fence, it seems that the principle of Judah's prohibition works.
Friend, I tell you in advance that there is no place in our galaxy for two Sabdarmish Yehudas!
I hereby solemnly declare, get with and know, if there is another Sabdarmish Yehuda, I will start believing in black guys and maybe, even, but just maybe, also in a dark mass.
By the way, Tehillim, tell your friend to check the identity number of the above.

Check a friend who works at the Ministry of the Interior - there is a Sabdarmish Yehuda in Gadara.

And with all the simplicity - if you add this mass outside the range of the stars in it, then the added mass does not solve
And with all the simplicity - if you add this mass outside the range of the stars in which it is, then the added mass does not solve the problem.
How do you prove that the required mass is ten times greater?
Simply, at the edge of the galaxy the speed should have been according to the visible mass only 70 km per second.
Since it is three times more, it means that more mass is needed, which is an amount times the square ratio of the speed.

Yehuda:
I don't understand the purpose of the calculation you did, but the dark mass outside the sphere surrounding the galaxy does not affect the relative motion of the stars within it.
As a general rule - the presented calculation is not physical in the conventional sense of the word because it is based on the ratio between the dark mass and the normal mass as a given and does not try to deduce the amount of the dark mass and its distribution in space from the movement data.
What problem are you talking about, everything seems fine to me.

Proof that most of the dark mass in spiral galaxies is found in the surrounding gas clouds
The radius of the spiral galaxy is given as 50,000 light years, and together with the surrounding gas clouds - 100,000 light years. Given the rotational linear velocity of stars in a galaxy is the same throughout its entire length to the edge of the surrounding galaxy clouds (about 220 km per second)
We will prove that the amount of mass at a radius of up to 100,000 light years is double the amount of mass up to a radius of 50,000 light years.
Proof: From the formula of motion in spiral galaxies:
m*m1*g/r^2=m1*v^2/r
where m is the internal mass of the galaxy up to the radius r. We will reduce and get:-
v^2=m*g/r
and hence v is proportional to the root of m/r, that is, to get a constant v at a distance of two radii we must also multiply the size of the mass m.
Since we know that the mass in the spiral galaxy is on average ten times the apparent mass, then in order to maintain a constant rotational linear velocity, half of the galaxy's mass is up to 50.000 light years and half of the mass is up to 100,000 light years. That is :-
Up to the edge of the galaxy (50,000 light years) we have 10% baryonic mass and 40% dark mass, and in the region of the galaxy's clouds up to a distance of 100,000 light years we have 50% of the galaxy's mass and all dark mass (the clouds of the spiral galaxy are very sparse in baryonic mass).

Good Day
Sabdarmish Yehuda
Hence most of the dark mass is concentrated around the baryonic mass of the spiral galaxy.
++++++ So this is the compromise regarding the censorship on the site? Deduct 10% from all responses. 🙂
In this area intuition is sometimes confusing.
I think on NASA's website I read the illustration in order to slow down a particle of dark matter
(if it exists) the entire solar system should be filled with lead !!!. If there was friction, or more
Makes sense - collisions. It was easy to discover the mysterious particles. About 75 years of trying already
capture this particle and without success. There are now several leading projects that are trying
To learn about the 'dark matter' particles and for now without success - PAMELA and FERMI
In space, LHC in Switzerland, ICE CUBE in Antarctica, a number of huge sensors in deep mines
In several countries and many more initiatives are ongoing. It's hard to think of a better recommendation than Tazer
patiently
Yehuda:
Somehow I get the impression from your words that you think the dark matter should be scattered on the outside of some sphere and not on the inside.
I have not seen such a claim and as far as I understand the dark matter also fills the ball.
It turns out that when I said in response 5: "I suppose that there may be places in space (I wouldn't call them galaxies because there are no visible stars in them) that only have dark matter"
I prophesied in relation to the past:
http://www.newscientist.com/article/dn7056
In response number 6, I meant that dark matter found in the inner regions of the nascent galaxy moves outward, and in its outward movement should also pull the bully with it, so how is it that stars are formed?. The whole move of opposing movement of the concentration of the dark matter outside and the bully inside even though they are supposed to attract each other seems strange to me.
The link in response 30 is very nice.
good evening
Sabdarmish Yehuda
Go to the next news
Yehuda:
If you read my response (11) that came right after you said that, you'll see that I noticed it immediately.
That's why I wrote: "The strange claim that the dark matter is supposed to pull the stars out is without any basis and is actually contrary to the laws of nature. It's like claiming that the mass in the Sun's mantle was supposed to pull the mass inside the Sun out and create a vacuum in the center of the Sun (and the same for the Earth). "
MOND was also specially adjusted so that the gravitation would start to increase (compared to that predicted by Newton) only after a certain distance.
Well done to the point
My mistake!,
Just the opposite!
In a spherical body, only the internal matter affects the force of gravity and not the external!.
It's interesting that only now has someone noticed the mistake.
In other words if for example I am at a depth of a thousand km inside the earth, I will only feel the gravity created by the earth without an outer shell of 1000 km. That is, a sphere with a diameter of 10,700 km instead of 12,700 km.
If I am at the center of the earth I will not feel gravity at all.
Yehuda, I did not understand the following sentence from comment 3:
(In a spherical body, the internal matter does not affect the force of gravity, only the external).
Can I explain?
Hi Michael,
Congratulations on the journalistic achievement.
It is quite clear that these are statements of significance on the part of the aforementioned individuals, certainly for the stakeholders but also for the general public. Therefore, it seems logical that he should do it in a proper and acceptable way. Why not arrange an arranged meeting with them, have a professional journalist join you (it makes sense to contact my father), do adequate preparatory work and produce a series of articles.
To my father - in a broad view of what is happening in the fields of interest of this site, there is a daily flood of information regarding 'you can't see the forest for the trees'. The Americans/Russians/Europeans/Japanese/Indians/Chinese, together and each separately. So many projects at the macro and micro physics level. CERN, ICE CUBE, ITER, the neutrino sensors, the gravity sensors, dozens of sensors and telescopes in space. So that's it, I think it's time to try to put some 'order in the mess', especially for the curious reader who is not from the profession. So maybe... you might have an opportunity here... grab it!
Regarding the Saul galaxy
Just, for good measure, she is called
M94, or NGC 4736
Nevertheless, thanks to commenter Shaul for introducing her to us.
Good night
Sabdarmish Yehuda
Hi Yehuda,
I really want to help you so I thought of some suggestions. Trust me it wasn't easy:
1. Call Stephen (Hawking) to save you.
2. Ask my father to delete all of Michael's comments.
3. Chew hard before you swallow (the cap).
post Scriptum. - Where did Yael go? She doesn't go out because we insulted her?
Friends:
Yes - I really spoke to you. I don't hesitate, and what I quoted from their mouths is what they did say (at least as far as I understood them - there can always be a misunderstanding, but I don't think it happened here).
Don't forget that they are just human beings and in my opinion even nice human beings.
Scientists usually try to see all possible ways to solve a problem.
Since the way of the dark matter was described and since there was also a possibility that the necessary result would be obtained by changing the formulas - they tried this way (and they still continue to try).
The motivation is, obviously, the desire for elegance and there is no doubt that a theory without dark matter may be more elegant - for example if it only changes some formula.
Beckenstein joined the effort because it was clear that MOND was wrong in that it did not predict the relativistic effects that had already been confirmed experimentally.
Therefore it can be definitely said that Bekenstein did not accept MOND but that does not distinguish him. I assume that Milgrom also knew from the beginning, when he developed MOND, that he would still have to improve it to handle the relativistic effects and Beckstein simply helped him in the further development.
In the conversations I had with them, it seems to me that Milgrom is more inclined to cut in one direction while Bernstein is also willing to accept a theory in which both the gravitation formulas are different and there is dark matter.
Milgrom prefers to work according to Ockham's razor and according to him - if, for example, a dark matter particle is discovered, he will abandon MOND and its derivatives completely.
I told Milgrom about Saul's galaxy and he said that he did not trust the results of the analysis performed on it.
There is no doubt that he would like some of MOND's derivations to turn out to be correct.
I forgot to contrast it with the fact that galaxies have already been observed whose center of gravity is elsewhere than the center of gravity of their visible matter.
See for example here:
http://en.wikipedia.org/wiki/Bullet_cluster
I'll let him rest for a while and get back to him with this question.
Hugin,
As a nightingale your beads are beautiful,
But I don't think they are written on such sites,
Your wisdom spreads like a deceived sky,
And I'd like you to talk straight to the point,
May you strive to fulfill your many knowledges,
But I would like to read from your responses only the answers to the questions,
nice evening =)
Avi Blizovsky
Thanks for the referral. The interview is outstanding. It's interesting how the questions were put together. I wonder whether under the guidance of Prof. Beckenstein himself. This may clarify its emphasis and direction.
Sabdarmish Yehuda
But he uses the word "relative" meaning that sponsorship in his opinion is a binding framework. In his opinion, there is indeed a need to expand it. Whether by increasing the dimensions or in other ways. Also pay attention to the section where he emphasizes the issue of information as a key future element in deciphering and correctly expanding the framework of astrophysics and physics. In addition, he strongly emphasizes the issue of abstraction and moving away from a simple intuitive state in order to understand these systems of laws.
I thank my father Blizovsky for the link to the interview with Jacob Bekstein,
The interview is long and the time of the science readers is valuable. That's why I allowed myself to find several "pearls" in the interview:-
A quote from Jacob Bekstein's words about the demand for an alternate gravitation theory:-
"It turns out that we don't see all the mass that causes movement. Following this, the existence of "dark mass" was proposed, an explanation that is widely accepted today. But there are certain difficulties in this view. There is another way to try to explain the observations and that is to say that the accepted theory of gravity does not work well on the large scales of galaxies and above, and a revised theory is needed." End quote
A quote from Jacob Bekstein's words about his support for MOND:-
"Today there are more and more features of galaxies that have a fairly simple explanation according to Milgrom's concept, and are more difficult to explain according to the concept of dark matter. And more and more people believe that this theory, which Milgrom calls MOND, works well. ". End quote.
The description of Professor Beckstein's path as it is expressed at the end of the interview:-
Jacob D. Bekenstein
Contributed to the foundation of the thermodynamics of black holes and other aspects of the relationship between information and gravity. Today he is engaged in the development of an alternative relativistic theory of gravity to general relativity that will make it possible to understand the universe without needing dark matter." End quote.
In short, the respectable professors have not left MOND and do not like the dark mass.
I really want to call the dear professors and ask them what exactly they said to the "representative" of the scientist today.

The interview with Prof. Jacob Beckenstein.
https://www.hayadan.org.il/bekenstein-021105/
To my father Blizovsky
The Hidan website published the interview with Jacob Bekstein that was published in Scientific American. I would ask you to provide us with a link to the aforementioned interview. It is impossible to get this link on Google. This way we can see what Professor Beckstein really thinks about the dark mass.
Also Le Sage's theory differs from my simple idea of the universe in that it corresponds to Newton's formula and therefore there can be no difference between it and Newton's formula regarding the reference to the dark mass.
On the other hand, in my simple universe idea, there is almost no gravitation at distances and therefore it is different from Newton for better or for worse.
I won't go into my endless debate on the subject again.
I must appreciate Michael's act of accessing the sources, although I believe he did not fully understand their words and his explanation as if they tend to give up the world or require the existence of the dark mass, it is exaggerated to say the least.
But again, I'm not a follower of MOND
Good Day
Sabdarmish Yehuda
Big brother, I agree with the wonder you brought, and I find it hard to believe that this is the case. I am attaching links on the topic of resistance to the dark mass:
a quote:
Two astronomers from Canada believe that there is reason to believe that dark matter, that mysterious substance that does not emit light, which most scientists believe constitutes most of the matter in the universe and which has not been directly discovered, does not exist."
And from Wikipedia. a quote:-
Mordechai Milgrom (born in 1946) is a professor of theoretical physics at the Weizmann Institute of Science in Rehovot. He invented MOND, the most successful and durable alternative to dark matter
It seems to me that there was some kind of interview with Jacob Bekstein, and I will try to find it.
In addition to not getting the impression that I am a follower of the Mond theory because I am not.
good evening
Sabdarmish Yehuda
If you're not indecisive about us... Wait, you're indecisive about us? Did you really talk to them?
So if you are serious, Prof. Milgrom also denied MOND. After all, why bother with an "alternative theory" if MOND is valid?
I took advantage of the conversation with Bekenstein => I took advantage of the conversation with Bekenstein to ask him
I forgot to mention in my previous response that I listened to the conversation with Bekenstein if he had heard about La Sage's theory and what his opinion was about it.
He told me that this Torah was disproved a long time ago and no one takes it seriously these days.
I forgot to ask Milgrom the same question.
The claim that Shasbari is wrong (completely or at all) is completely wrong.
Just as normal matter is not uniformly distributed - so is dark matter.
None of them were ever uniformly distributed.
The strange claim that the dark book is supposed to pull the stars out is baseless and in fact contrary to the laws of nature. It is like claiming that the mass in the Sun's mantle was supposed to attract the mass inside the hot Sun and create a vacuum in the center of the Sun (and the same for the Earth).
This is utter nonsense.
Putting in the expansion of the universe doesn't change anything, of course.
I have already mentioned before that I have never seen Milgrom or Beckenstein disagree with dark matter, but before writing this comment I decided to talk to both of them.
Beckenstein says that in his opinion there is actually dark matter, or in other words - that there are phenomena that he cannot explain except through it.
He claims that Milgrom and he try to explain some of the phenomena explained by dark matter in a different way.
Milgrom says his opinion doesn't matter.
He tries to develop an alternative theory and in the end experiments will decide between the theories.
One can develop all kinds of theories about why they allow themselves to make claims that differ from those attributed to them.
Besides, we're just looking for the best explanation.
As you can see in the link I gave - the vast majority of professionals see dark matter as the best explanation.
There is also data that apparently contradicts MOND. One of the examples of this data is the Saul galaxy - http://www.newscientist.com/article/dn13280 And another example is galaxies whose center of mass is not where their visible matter is concentrated.
I am repeating most of the things here for at least the tenth time, but I am glad that this time I could also renew following my conversations with the only two scientists mentioned as disbelievers in the existence of dark matter.

Sabdarmish Yehuda
Is there an article about the MOND theory on the science website, I read a bit on the net, and I would like a clear article on the subject on this website.
The Israeli angle of the theory sounds particularly interesting.
I also have a proposal for a solution, but for this purpose I removed the 'website' from the internet...
First you need to understand how the sun works: the sun is not hot or heavy enough to produce nuclear fusion as in hydrogen bombs it is said. So how does it still happen?, the sun uses a rare phenomenon called "quantum tunneling" to bring two nuclei together and perform fusion, this is a phenomenon that only happens once in a zillion times, but since the sun has a zillion zillion particles, the phenomenon still happens.
Now I will jump to another natural phenomenon: a Coke bottle is said to look completely clear when it is corked. Open the cap and many gas bubbles appear. Where did the gas come from and why was it released only after opening the bottle? The gas was dissolved in the liquid and the liquid was under pressure. As soon as we released the pressure the gas went from a dissolved state to a gaseous state and we saw bubbles.
And for a possible explanation: the sun 'charges' the space/space/ether with energy that is dissolved in the 'ether' and the gravitational pressure makes this possible. Moving away from the sun the 'pressure' decreases and the energy is released from the 'ether'. It also reminds a bit of 'hacking' in transistors.
I don't understand too much about it (and maybe it's complete nonsense) but maybe it has to do with the light
Perhaps the intense heat of the sun affects the light in some way so that its effect
The light is only seen in places further from the sun and colder.
to Luke
The explanation that dark matter is everywhere with nothing to do with normal matter is a completely wrong explanation!, if he didn't care then he should be randomly everywhere!
But, it is a fact that in any spiral galaxy it is almost never found in the inner parts, and is mainly concentrated in the outer parts!
In addition, how does the explanation that it is also frictionless sound to you?
What would it look like to you if stars were formed with dark matter pulling the material out?
How would it seem to you that the universe is expanding in an accelerated way instead of actually contracting?, with so much dark matter with "blessed" properties of attraction the universe should have actually contracted.
So what do we do anyway to explain the accelerated expansion of the universe?, we have to add dark energy to the universe that will actually cause it to expand!
In short, dark matter is a poor convention for things that do not know how to explain them in cosmology, and because of these and other poor explanations, there are many scientists who are not ready to accept this convention.
Two of the best Israeli scientists, Professor Milgrom and Israel Prize laureate Professor Jacob Bekstein, do not agree with dark matter and even developed a new theory called MOND that tries to explain the movement of galaxies without dark matter.
http://en.wikipedia.org/wiki/Modified_Newtonian_dynamics
And there are others too.
You should know that the explanation of the dark mass is acceptable and maybe "kosher", but "smelly", and even very!
Good Day
Sabdarmish Yehuda
Luke:
Dark matter and normal matter do not have to be in the same place just as normal matter and other normal matter do not have to be in the same place.
After all, according to this logic, all the material should have been in the same place.
There are even entire galaxies that have no dark matter in them and I suppose there may be places in space (I wouldn't call them galaxies because they have no visible stars) that only have dark matter.
Dark matter does not interact with normal matter except through gravitational interaction.
Probably also that, with the exception of extreme cases, he does not maintain any other interaction with himself.
Without this type of interactions - there is no possibility that the dark matter will concentrate to a certain point because all its particles are always in motion under the force of gravity.
If you ask yourself how it is that the normal matter concentrates to form a star you will understand that this cannot happen without friction and electromagnetic force.
After all, without these forces, its movement would also continue and any two bodies that collide or pass in close proximity to each other would be splashed apart or continue to pass by each other.
Since the dark matter does not "suffer" from friction - this is exactly what happens to it.
Normal matter in a galaxy is forced to organize itself in the form of a disk surrounding the center of the galaxy precisely because of the non-gravitational interactions it maintains with itself.
Dark matter - precisely because it is not subject to the same interactions - has no reason to organize itself this way.
Therefore, dark matter seems today (to scientists) to be the most logical explanation for many phenomena - as you can read in detail here:
http://en.wikipedia.org/wiki/Dark_matter
The previous response - 3, is my response.
to Luke
Your logic works, but it doesn't!
In the spiral galaxies, for example, one of the anomalies of the dark matter is that it is not found near the normal baryonic matter, but rather mainly outside the spiral galaxies, in the surrounding clouds. This is the only way to explain the constant rotation speed of the galaxy (in a spherical body, the internal matter does not affect the force of gravity, only the external).
Therefore, despite your logical conclusion, the dark matter is not involved here, and in addition, the concentration of the dark matter that is not near the normal matter is mysterious, and requires an explanation, and it is not certain that it will be found.
Good Day
Sabdarmish Yehuda
Someone once examined the idea that the two phenomena appearing in the article and the ones the probe is supposed to investigate, are related to dark matter or dark energy.
After all, if dark matter is known to interact with gravity, it is likely that it will be found in places where gravity is high, such as in the vicinity of the Sun.
I will be happy to respond
We must arrange sunglasses for the poor probe
