Static galaxies

[tex_1224]

Why does all the matter in a Galaxy rotate around it's center as a whole, no matter the distance from center, while in a solar system, the rotation of matter is affected by it's distance from center?<br /><br />Could we think of galaxies as cellular creatures? Is there a membrane that seperates what is inside, and what is outside of a galaxy?<br /><br />Could this static that binds all matter in a galaxy be what humans consider God, or the so called 'holy spirit'? If it is a being, than what about all the galaxies in the universe? Could they all be Gods too? <br /><br />Could the static that binds all galaxies be the "Higgs field"? that which partical physics is trying to prove exists?<br /><br />What does it mean for civilization in our window of existence that all things rotate around the center of a galaxy as a whole, in terms of inevitability? Can we then predict the inevitalble path(s) of all matter within the rotation of a galaxy?<br /><br />Can we then calculate the windows of existence of which life may exist on planets other than our own?<br /><br />Can we find a way to cut through this static field that binds all things within a galaxy to travel great distances without taking light years to get there? or would we just unravel the very nature that bonds all things together?<br /><br />What about when two galaxies collide? What happens to the structures as a whole in terms of the static unison? do the static membranes melt into one, or does the collision destroy the membranes like the bursting of a balloon?<br /><br />What is the static that binds all things in a galaxy whole? Simple Gravity is not enough.

Matter in a galaxy does not rotate around the galactic center as a whole. Nearby stars such as Barnards will pass the Sun so to speak. That is, Barnards will come closer to the Sun several thousand years from now then move on. Indicating it is moving a little faster. Stars, nebulae, and other objects closer to the galactic center orbit the center faster than those outside. If one could view the milky way from well above and view it as it was 250 million years ago, and now...then compare the views. You'd most likely see that they would appear similar but not exactly the same.<br /><br />Galaxies appear to be one massive object because galaxies contain so much more matter than stellar systems and galaxies rotate far slower because of their size.<br /><br />Tex_1224:<br />Could we think of galaxies as cellular creatures? Is there a membrane that seperates what is inside, and what is outside of a galaxy?<br /><br />Me:<br />From what is known by observation. No membrane like structure has been detected. Stars actually can be ejected outside the galaxy over periods of eons. One was recently observed well above the plane of most stars in the milky way galaxy and well above the center. I cannot recall the link now but someone here will probably know.<br /><br />Tex_1224:<br />Could this static that binds all matter in a galaxy be what humans consider God, or the so called 'holy spirit'? If it is a being, than what about all the galaxies in the universe? Could they all be Gods too?<br /><br />Me:<br />Thats kind of like saying the Sun was a God. And at one time, thats what people thought. The Sun or Planets were Gods. No way to really know as long as Galaxies and other celestial objects behave as natural rather than supernatural objects.<br /><br />Tex_1224:<br />Could the static that binds all galaxies be the "Higgs field"? that which partical physics is trying to proove exists?<br /><br />Me:<br />Could be, but won't really know for sure unless or until physicists are able to prove its exist <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

That was certainly as complete of an answer as was needed. Good job, now just hope he doesn't need links too.. <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

Well, if he does, he can find them. I answered this in a more general sense because it appeared he was looking for a more philosophical or religious answer to his questions. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

Agreed. I would just add to further show the complete fallacy of the premise, the star closest to the black hole has been tracked through one complete orbit, it took 17 years, hard to say that a galaxy that has our sun orbiting in 250 million years, and another star orbiting in 17, is "orbiting as a whole."

So your saying galaxies aren't a whole. If our galaxy is not a whole, than why do we call it a galaxy? what makes it a spiral? what makes it a cluster? Why are galaxies large groups of star systems? what makes a solar system apart of a galaxy? Why is there so much empty space between galaxies? <br /><br />when I look at pictures of galaxies they look like one mass. like one spiral galaxy. you cannot answer my question. <br /><br />What is the ratio of the rotation curve of a galaxy compared to the rotation curve of a solar system? regular gravity doesn't cut it.<br /><br />So take into account all of the matter we see in the milky way. Well, it's still missing about 70% of the matter needed to hold the galaxy together. so around 70% of the milky way is Dark matter. in fact. all galaxies are about 70% dark matter. <br /><br />What is holding galaxies together when all the matter we can account for is not enough to hold the galaxy together? Does that mean every star has a system of planets?<br /><br />Is the biproduct of a star, planets? are planets but failed stars? Are stars the biproduct of what is at the center of a galaxy? Are stars but failed galaxies? could these planets make up the missing matter in a galaxy? Are planets the dark matter? we can't see planets like we see stars, but we can see some of them by their shadows. what about the planets that are there, but never cast a shadow between us and its parent star? how would we ever know it is there? <br /><br />

Tex_1224:<br />So your saying galaxies aren't a whole.<br /><br />Me:<br />Correct.<br /><br />Tex_1224:<br />If our galaxy is not a whole, than why do we call it a galaxy?<br /><br />Me:<br />The excerpt here is a dictionary definition of galaxy:<br />"a. Any of numerous large-scale aggregates of stars, gas, and dust that constitute the universe, containing an average of 100 billion (1011) solar masses and ranging in diameter from 1,500 to 300,000 light-years. Also called nebula.<br />b. often Galaxy The Milky Way."<br /><br />Nowhere is it called a whole, or in any way is everything in a galaxy implied to be in motion all at the same rate. Now they did mention also called nebula which I think is wrong. Nebula are collections of gasses usually left over from past nova/supernova events and nebulae are found in galaxies. Nebula and galaxies were once though to be the same or similar objects before astronomer Edwin Hubble (Hubble telescope namesake) showed the true nature of galaxies as existing outside our own galaxy.<br /><br />Tex1224:<br />when I look at pictures of galaxies they look like one mass. like one spiral galaxy. you cannot answer my question.<br /><br />Me:<br />Take a closer look. You will see black voids, spaces inside galaxies, dust lanes and stars fill in much of a galaxy but there are those black voids as well.<br /><br />Tex_1224:<br />you cannot answer my question.<br /><br />Me:<br />Maybe not in the way you'd like it to be answered but you can also do further research and see how galaxies are. You mentioned spiral galaxies, there are also barred spirals, ellipticals, irregulars...see the link I have here:<br /><br />http://zebu.uoregon.edu/~soper/Galaxies/types.html<br /><br />Tex_1224:<br />What is the ratio of the rotation curve of a galaxy compared to the rotation curve of a solar system? regular gravity doesn't cut it.<br /><br />Me:<br />Take a read of the link below to get a good overview of ro <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.
