I found the episode on youtube: https://www.youtube.com/watch?v=oq_pZub-QTc Please note time stamps: 8:16 Begins the sections about forming stars 9:25 the statement "..gravity is alone is not enough" 9:43 Talks about angular momentum. 15:57 it begins talking about galactic magnetic fields 20:42 & 24:36 It refers to energy waves moves through dust clouds creating magnetic fields.

True, but the show countered this point by stating that EACH dust particle has becomes charged due to... solar winds, super novas, etc... Now the magnetism doesn't have to go as far, just to the next charged particle. Does that make sense? (Please forgive me if my verbiage is incorrect. I am trying to quote the show, and I am not a scientist myself. Just highly fascinated with it though!)

I am not debating the existence of dark matter. I am wondering if the amount of dark matter is correct. The amount is based on calculating how fast the outer stars are orbiting their galaxy and what mass is required to hold them in place.; Galaxy rotation curve. (It is also calculated by the amount of gravitational lensing.) So, if magnetism is helping hold stars in place while they whip around a galaxy, then shouldn't that reduce the amount of calculated dark matter?

Something along the lines of: Due to angular momentum, dust clouds are not suppose to condense into stars; The gravity isn't strong enough. However, when the magnetic field is examined of the charge dust particles a different picture comes to play. The magnetic field would be strong enough to pull the particles closer together, thus helping gravity in this case. The part with Dr. Plait was pointing out is that magnetism is responsible for keeping the spiral arms of galaxies together. Since there isn't enough visible mass to keep everything where it is, researchers looked into magnetism. They found where the magnetic field concentrated at, the dust and other material would stay there...thus an arm of the Milky Way.

I just watched an amazing episode of "How the Universe Works", season 4 episode 1: Forces of Mass Construction. The episode was discussing the role of magnetism in the universe, and how it is a lot more than previously thought. There was a portion where astronomer Dr. Phil Plait stated that the shape of the Milky Way's arms are due to magnetism. Then they showed this special effects how magnetism actually prevents and creates star formation. However, I thought dark matter is the reason why galaxies don't fly apart and forms stars. So, is the theory of dark matter starting to disappear due to the discovery of magnetism on the galactic level?

That makes sense. Then, we find "Hot Jupiters" just to muck everything up! I know the going theory is they formed then got trapped by their accompanying star: http://www.universetoday.com/109269/what-are-hot-jupiters/

Thank you! I will defiantly look through these. The solar wind is responsible for creating the tails of comets. http://hubblesite.org/reference_desk/faq/answer.php.id=18&cat=solarsystem Also, it is believed that the solar winds are responsible for Mars' nearly lack of an atmosphere. "For clues, MAVEN will watch to see when and how gas is currently stripped off the top of the atmosphere—a process that is thought to be driven by interactions with the solar wind. “The question is whether over long periods of time this process or any of the other processes that are operating have been responsible for removing most of the gas,” ..." http://www.scientificamerican.com/article/maven-spacecraft-mars-atmosphere/ The solar wind has been clocked at over 1 million miles per hour: http://solarscience.msfc.nasa.gov/SolarWind.shtml Then you have this explanation that actual states the solar winds blowing the dust away during the formation of the early solar system. "This is called the solar wind. Radiation pressure and the solar wind in the early solar system essentially blew all the excess gas out of the inner part of the solar system. That is why the terrestrial planets are so small -- the light gases were blown away." http://www2.astro.psu.edu/users/caryl/a10/lec18_2d.html I understand that solar winds having very little affect on planetesimals, now gravity from itself or the sun can prevent it from being blown away, but it appears that solar wind does have a very strong effect on dust size particles. Which now causes me to edit my original question. Obviously planets form... How did solar wind not prevent this over the time period it take dust to form into planetesimals? The rings of our gas giants have the protection of their hosts' magnetosphere. Dust orbiting a star, does not have that protection.

I came across this article that talks about how in the HL Tauri system new planets can be seen forming around the star. Then later in the article it gives a link to "Its always wind around this baby star" http://news.discovery.com/space/astronomy/revolutionary-new-view-of-baby-planets-forming-around-a-star-141106.htm http://news.discovery.com/space/astronomy/its-always-a-windy-day-around-this-baby-star-14092.htm Here is my question: Space is affected by mass, that space gets 'dimpled' by the planets thus giving us gravity. How then can dust particles and small rocks create enough of a gravity well that will prevent the solar wind from blowing it away? How can gravity, a weak force already, have any kind of influence on dust and small particles if there is a stronger force that would seem to prevent it?

Humans are... well humans. We make mistakes, we have plans that mainly concern ourselves. A family man will put his offspring before a homeless, a rich man will put his money before another. Very, very few will you find someone who puts others first. Off the top of my head, Medal of Honor recipients, teachers, firefighters and police are a few that have put others first at some point in their lives. They are truly amazing people. John 15:13 "Greater love has no one than this: to lay down one's life for one's friends." But, even the best of us are not perfect, sinless. I can be utterly amazed at a persons action, but that does not mean I will bow down and follow them. I would want them in my corner, or on my team, but I only follow one coach. One King. John 5:43-44 "I have come in my Father’s name, and you do not accept me; but if someone else comes in his own name, you will accept him. How can you believe since you accept glory from one another but do not seek the glory that comes from the only God"To answer the questions from the OP: Why you need to give preference to GOD rather human. God created human. Sports analogy, why follow the player? Follow the coach, the teacher. Whom you know better? Fellow Human or GOD. God Why you want to go to heaven at the sake of killing your fellow humans. I want to be in God's presence. I have not, nor been asked to kill fellow humans. Do you know heaven/GOD exist? but your fellow human are real. Yes. So. A stone is real, a plant is real. That doesn't mean I will believe in those. 2 Corinthians 4:17-18 "For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal." Who you have seen and talked? God or fellow human. I speak with God daily. My eyes are not worthy, incapable to see Him yet. Exodus 33:20 "But,” he said, “you cannot see my face, for no one may see me and live.” Whom you afraid of? GOD or fellow human, God. All human can do is stop my life here on earth. Proverbs 1:7 "The fear of the Lord is the beginning of knowledge, but fools despise wisdom and instruction." Why you start hating the human if he didn’t believe in your GOD? I don't hate. Everybody has their own choices and paths to pick. Why you think your GOD is superior to his GOD? What other God? There is one and only one. Deuteronomy 4:35 "You were shown these things so that you might know that the Lord is God; besides him there is no other." 1 Corinthians 8:6 "yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live." Why you want to establish your GOD kingdom over all Humans? Who asked you? Why? What his (GOD) purpose? This is not my want, it is not my Kingdom. I do not walk into your house demanding food or rearranging the furniture. Psalm 103:19 "The Lord has established his throne in heaven, and his kingdom rules over all." Why you want everyone to believe in what you believe as GOD? I doesn't matter if they believe in what I believe. A relationship with Christ is personal. You pray, confess and follow with Him. I am nothing. Why you spread propaganda with other humans to convert in believe in what you believe? I am not converting anybody to what I believe. I am spreading The Word. It is their choice to follow. Matthew 28:19-20 "Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.” Why you act as puppet in Hand of GOD to hate your own human beings? Again, I do not hate. I am not a puppet. When your father tells you do something, you obey out of respect and love. Not because your a puppet. Why you act as puppet in Hand of some people in the name GOD to hate your own human beings? When even those people never seen the GOD? This is repetitive. If the GOD just talk about loves and just loves why daily there is thousands of killing, conversions, preaching and so many things, other than love as well etc. why can’t be it just simply love ? Because humans make bad choices. Everyone of us, from the person to the head of Church Organizations to even heads of States (Countries). If your actions are not for God, then your actions are selfishness. Yes, God commanded the death of over 100,000 people in the Bible. We do not know His plan. We do not know that the death of a person saves the souls of thousands. We do not know how that person was judged at death. That is not my job. Death on earth is not the end. Romans 3: 10 -18 "As it is written: “There is no one righteous, not even one;... " Proverbs 3:5-6 "Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight."

As long as man sits on the thrown, there will always be strife. As for me, there is only one worthy enough for me to kneel down to and pledge my life to. John 14:6

I couldn't agree more. Anything can be compared to a virus then. From clothing attire to language and even to sporting events. (The shrine of the tailgate)

I've always struggled with the question of 'space'. Even started 2 different threads asking questions and some amazing answers have been given. More importantly, simplified for my simple brain! I've wondered the same thing here. If you have 2 balls suspended in water, floating half way from the surface and bottom. The balls can be pushed apart, thus adding more space between them, or more water can be placed between them. Literally adding more space between them. In once case the balls are moving, the other case 'space' is moving. To be silly, Scotty from Star Trek stated that, " Imagine that! It never occurred to me to think of SPACE as the thing that was moving!" Mordred and Strange, I understand your answers. For some reason they are not making sense to me. How do we know space is expanding when we can't see the 'walls' moving away from us? We can see stuff moving from us, we can measure the volume based on what we see. But we can't see passed 46 bLy. If space is infinite, then we are missing a very big portion of the equation.

You are not naked, nor are you wearing a crown. The word used in the Greek Bible was στέφανος or "Stephanos". Meaning a wreath, or more correct a reward. And the word "take" was λαμβάνω. This does not mean to steal, or remove from someone/something or forcefully own. It means for someone to receive. As in, someone else will receive your reward. To answer the question about what we will wear: 1 Corinthians 15: 35-58 Paul the Apostle talks about how our earthly body is only a seed to our heavenly body and verse 49 states "And just as we have borne the image of the earthly man, so shall we bear the image of the heavenly man." Then look at Philippians 3:20-21. "But our citizenship is in heaven. And we eagerly await a Savior from there, the Lord Jesus Christ, who, by the power that enables him to bring everything under his control, will transform our lowly bodies so that they will be like his glorious body." I don't not know what we will be wearing physically, nor do I care. I do know that what ever form it will be in, it will be perfect, sinless.

What... media has something wrong? Again? "Why Ike, whatever do you mean?" Good point Orodruin! I thought I understood expansion to be similar to compounding interest. For every Megaparasec the expansion is increased, again? Why would expansion not be evident until 200 million LY?

A few days ago I read about this globular cluster of stars coming at us 'like a cannon ball'! (reporters crack me up!) According to the article, there is a cluster of 100,000 stars heading this way from 53 million light years away. They are figuring it will be here in about 17-18 million years. Now please bare with me, I might start talking out of my butt here... but if the cannon ball is traveling at 2 million MPH(according to the article), which is 894 Km/sec, isn't space expanding faster than that with these kind of distances? Expansion increase the further apart items are, right? I get the fact Andromeda Galaxy will reach us, it is only 2.5 ly away. Will this 'cannon ball' ever reach us?

Spyman and BearofHN... thank you for explaining it so. Spyman, interesting tidbit there of 'Tired Light'. It goes to show that there is so much more to light than what we can see. My own explanation could have answered this for me. Just because it appears different (further or closer) doesn't mean it is. I teach pilots to trust their instruments, and that is exactly what scientist do. Trust their instruments. Thank you.

Not to be a wet blanket, or maybe I am not understanding here... but NFW? I can think of the asteroid belt between earth and mars, the Oort cloud and the milky way that would be in almost every picture? Or am I missing something?

Great point! I remember the news media being in a frenzy but once you started reading the articles... well... the truth came out. Thank you Spyman, that makes a lot of sense and does a lot to clarify. Now, to play devil's advocate, how do we know that light isn't distorted by dark matter? We've been looking at the stars for a few years now and haven't noticed the gravitational lensing until very recent. (Last year I think?) What about the expansion of space, could that stretch the light into red, yet the actual distance is a lot closer? In the flying world, I teach students that anything between your eyes and an object will make the object appear to be further away. ie: fog, dust, rain, bugs on the windscreen... what if we are simply looking through a lot of 'stuff'?

Two questions here. The first is about the red shift of light and it came about in another thread called galaxy rotation curve. The answer I understood was, we can determine the rotational speed of galaxies by the red shift of their light. So I went to Google and stated to research red-shift which led me to my question: How do we know that light is red shifted because the light source is moving away from us and not from something else? ie: Gravity has been proven to affect light, couldn't the source be closer and simply shifted red? (Black holes, dark matter...etc) Second question, in researching red shift I came across many weird sites that claim they have proof against red shift, big bang, the Twinkie theory and so on... it gave me a headache reading them all and reminded me of traveling salesmen offering cocktails given to cure all ailments! How can someone protect themselves from science lies being wrapped with some truths? As a professional pilot I hear all the time younger pilots using terms incorrectly or distorting them to simply fit the question. How can a non-scientist, who has a fascination about 'Outer Space', not fall for some of the gimmicks out there? Thank you in advance...

Yes. There are two basic forms if drag, parasitic and induced. One is parasitic is related directly to speed while induced is inversely related. At some point you get the perfect balance between two different designs. Same with planes, trains and automobiles. At some point, it isn't cost effective to keep changing the angle or shape.

If you look at many of the religions that had a pantheon of gods: ancient Egypt, ancient Greece or Rome, Norse; or even religions that worshiped the elements or nature, like many native Americans or wicca; even the religions based upon ancestry worship: many oriental beliefs or ancient Egypt... and lets not forget the darker religions, voodoo and 'black magic'; These type of religions always had the persona of the person praying placed into the deity. The deity wanted the blood, wants money, wants... desires... go get earthly possessions. The deities had the same desires as the people, they even bedded with us! It was also easy to blame the supernatural when something goes wrong, the perfect rationalization. "zeus got her pregnant." "devil made me do it" or "they cast a spell on me." All of these where created out of a want or desire to have something watch over them, or more powerful. When an answer was not known, instead of saying "I don't know lets figure it out" they came up with the most creative imagination possible. Then you had those with a little more common sense and created power by calling themselves 'god-kings' and so forth. That is the most amazing concept about Him, Yahweh, I am, God... He didn't want mindless drones simply following orders. He gave a simple command, obey Him. He doesn't want a temple, we did. He allowed us to build Him one and when we disobeyed he tore it down. He never gave us a symbol, an effigy, a trinket to hold up. We begged for a king, and then began the kings over a thousand years that kept failing the people. Even the King David and his Son Solomon sinned horribly. He has never wanted blood, sacrifice, or money, land or power. Simply obedience. So to answer you question, before the beginning there was God. He has always been there, and always will. Since he made, everything, yes. He is perfection. We are just now beginning to understand the fullest extent of that. As we look deeper into the planck length, or further out into the clusters and filaments, we see the vastness of His perfection. Side note... before quotes from the Old Testament about sacrifice and blood come forth, I ask you to read the whole story first. The sacrifice and blood was means of tithing, giving up the early possessions and giving yourself spiritual to The Lord. A means of asking for forgiveness. He always showed forgiveness and love, all we have to do is ask for it. The ultimate display of love is self-sacrifice. John 15:13

Ooohh... I see. Red shift of the light is used. Thank you. In addition to your question (in which I was going to ask as well) Why does the inner parts (systems) act differently than the whole? Why would the galaxy spin/rotate different than the planets orbiting the stars inside itself?

Greg, I understand what you are saying. That makes complete sense on the planetary level. However, on the galaxy level, everything is said to move at the same orbital speed. How is that possible with systems of different masses, distances and so on? (I know this eventually leads into other threads about dark matter, so I want to make sure I am clarifying my question.) How can other galaxies orbital speed be measured when there is practically no rotation during our life time? The formula above proves that if the masses or distance are different, then there should be different speeds. Yet is has been proven they entirety of a spiral galaxies (maybe others?) orbits at one speed.

This still just baffles me and I was hoping it can be explained better. How do we know that an entire spiral galaxy is spinning at the same speed? I mean, we (solar system) haven't even made it one lap around the milky way yet. How can we tell that other galaxies are spinning at all? For simplicity, I was reading on Wikipedia: "...a new sensitive spectrograph that could measure the velocity curve of edge-on spiral galaxies to a greater degree of accuracy than had ever before been achieved. Together with fellow staff-member Kent Ford, Rubin announced at a 1975 meeting of the American Astronomical Society the discovery that most stars in spiral galaxies orbit at roughly the same speed." Roughly? Obviously this have been proven, but it surprised me when I learned that so much study was placed on on observation conducted within a decade. Pluto hasn't even made it a full orbit around the sun since it was discovered, yet we can see how fast a spiral galaxy is spinning? Thank you in advance for the education I so obviously need...

I'm sorry. I was not trying to mislead you or confuse you. I was really trying to show an example where the language is different; One, when the people right there in front of the speaker was the subject of the sentence and in the other, the people in front where not the subject of the sentence. I will admit, there are many passages in The Bible which may seem misleading and/or confusing. How many times in our own lives we read/heard 'zig' when in reality it was 'zag'. Then when translations are brought into the mix... good grief... now we have debates over the meaning of 'Yom'! Now, add into the confusion on 'free will' and 'possession' things are beyond muddled up. That's why its called faith and not science. John 20:29
