let me ask you a philosophical how do you know that the green your mind tells you is green is the same as the green my mind tells me is green

a little off topic im not asking about the color emitted by a star but the interpretation of that color by our minds

Sorry in advance.

     Since when is 1 in 6 * 10 to the 21st power unrealistic. They say evolution is probable which is 2.4 times 10 millionth power that we evolved from the ground with the right conditions. Out of the estimated planets in the universe the estimated number of planets with earth conditions is 10. 

     According to recent astronomical discoveries going off the fact that all 8 of our planets orbits r considered round. They have found that only 1 in 1000 planets have round orbits. The rest r eliptical.

     Most stars r red even if our sun is yellow.

     Most stars come in pairs of 2-4 and not 1 even if our sun is by itself in the solar system.

     Just some notes on whats realistic.

see this post from harvard's website, http://www.cfa.harvard.edu/news/2006/pr200611.html, it states that in fact most star systems are single and most planetary systems are single, as it's believed that it's harder for planets to form in a multiple star system.

Although I'd like to see multiple star systems in the game, I wouldn't like it to be the common theme, and should stars be any color it would be acceptable.

Why not have brown dwarfs??

Here's a philosophical, no a rhetorical question for you. How far off round does a planet's orbit have to be to be considered elliptical. I just checked wikipedia and found:

A circular obit is one where the eccentricity (orbit deviation) is 0.

A Kepler orbit is one where the eccentricity is between 0 and 1. (non-inclusive). This term comes from Johannes Kepler of the early 1600s.

Parabolic escape orbits and hyperbolic orbits, from what I was able to understand, seem to be one shot occurrences, since Wikipedia describes them as cases where the orbiting object escapes the orbited object. I really don't understand why these are called "orbits", but I don't think they are germane to our current discussion.

The use of "round" in reference to a planet's orbit is not used, but "circular" surely fits what you are describing.

However:

Mercury has a Kepler orbit, with an eccentricity of 0.205

Venus has a Kepler orbit, with an eccentricity of 0.0067

Earth has a Kepler orbit, with an eccentricity of 0.0167

Mars has a Kepler orbit, with an eccentricity of 0.093

Jupiter has a Kepler orbit, with an eccentricity of 0.0488

Saturn has a Kepler orbit, with an eccentricity of 0.0557

Uranus has a Kepler orbit, with an eccentricity of 0.044

Neptune has a Kepler orbit, with an eccentricity of 0.0112

And, just for comparison,

Haley's Comet has a Kepler orbit, with an eccentricity of 0.967

As you can see, all eight of Sol's planets except Mercury have a small orbital deviation, all less than 0.1, but none of them are considered circular.

     I'm actually going to reply to both of you. According to the astronomy teacher I had this year Who is currently working on the probe that is studying weather patterns on Jupiter who is currently an astronomer says that astronomers consider that deviation circular, and they only find 1 in a 1000 planets circular. If they r referring to an orbit eliptical they mean a lot greater eccentricity. I don't make the terms they do. The reason I mentioned what my teacher does for a living in 2013 is to point out his qualifications. In spite of termonology U r right not a lot of objects in our solar system is perfectly circular.

     Now thanks for the information on single stars I guess I was wrong about that unless they have changed their opinion about that since 2006. As far as the planets go a lot of things have changed like they have found at least 10000 planets because of the planet finding probes. The orbits of every planet they have found is more like pluto than Mercury, and the smallest sized planets r now the size of Mercury.

     The orbits of the planets r not perfect circles, but they r circles as far as astronomers r concerned. I guess they compare the orbits to other objects orbits, but out of 10000 planets only 10 of them don't have orbits that r more like pluto's. 8 of those r in our solar system. I guess that modern Astronomy, Wikipedia, and Johannus Kepler disagree on this issue. I would like to point out that Johannis Kepler couldn't really see our stars that well. Astronomers and probes can at least see it better for right now. Later they will probably see it better.

     About the sneeches kind of funny haha.

According to Wired, that's 10 billion Earthlike planets may exist in the Milky Way. I mean, I have no issues with bringing up science, but how does one even predict there are only 10 Earth-like planets in an infinite space? That makes no sense. 

According to my astronomy teacher given the conditions that make a earthlike planet. Mainly things like our moon and things like saturn and Jupiter. Our near circular orbits. Thats just a few out of fifteen conditions that make our planet the way it is. It really the difference based on modern knowledge of astronomy and wishful thinking. Oh I can find the conditions, but I'm not smart enough to crunch the numbers. Most of these numbers come from evolutionists and astrobiologists, but mainly evolutionists trying to put in biased conditions to create a scenario for life to exists in a computer simulator, and that is what a computer pops out. This also includes our knowledge of physics, microbiology, and chemistry. It's the difference between science and wishful thinking. Some people r trying hard to make science not to admit to a creator, but computers r there biggest enemy. They aren't smart enough to be biased.

But MoO Has event purple stars!! ..

Yes, the Drengin Empire fleet orbiting Earth (which inside a giant bubble of invincibility) demands realism.

What color does the sun look to you?  Does it look green?

I don't understand what point you are trying to make here. If you're saying that life couldn't have occurred by chance and that you believe a higher power or a deity created life then thats fine, you are entitled to your beliefs and there is never going to be proof that such things don't exist. If you're using the limitations of current computer systems to model theories as a basis to say science is bollocks though then you and I have a problem.

On the topic of green stars: Most of what we know about stars is from studying our own sun. There is no substitute for going out there, sending a probe would be the most logical choice, and looking at other stars. the closest of which is 4.2 light years away from us. With current technology if we launched a probe now it would take 13,000 years to reach alpha centauri. And by then the probes power source will have run dry (assuming it doesn't collide with anything on the way). Other stars could be very different from our own sun, we just don't know, so until we do, let those who write fiction about space have their fun with multicoloured stars and other things that may or may not be true.

Don't you know Galactic Civilizations is scientific fact, games are the new text books lol,

I'm all about simulating the real universe but, it's a game, SD has a right to add things as they see fit, or "what looks cool" after all it is just a game and not scientific fact, don't take the game in place of reading your information from reliable sources.

Excuse me if I'm mistaken, but I don't recall ever having had a conversation with you.  That being said, it's hard to ignore an invitation such as yours. 

Your philosophical belief system is not at issue here.  You can believe whatever you wish.  I prefer hard science, but you go ahead and discuss your faith as you see fit.   

In this case, green is light, the wavelength of which falls roughly between 520nm to 570nm.  Its frequency is in the range of 525-575THz. 

Our own Sun's peak light emissions fall within the green range, so it can be said to be a green star.  

In fact, with the billions of stars within our own galaxy, there are many more stars that emit green light. 

Your eyes can't see it, but there is also infrared and ultraviolet light that falls outside of your ability to see.  Whether you wish to believe it or not, these colors exist.  There has even been a technology around since the late 1950s that can take infrared light and convert it into viewable photographs.  Amazing as it may seem, this is real stuff that you can hold in your hands.  

In fact, there are many things that you can't see, but they exist.  Black holes, X-rays, viruses and ideas among others.  

LOL!  And there's that too.    

hypothetical experiment take a child and raise it but for this childs first ten years of life you tell it white is blue

when the child turns ten ask him/her what color the sun is and they will say blue because they would believe that white is called blue
