New forum game based on zombie attacks. Play either at TAU or here in this topic, but the info is linked to on http://www.tauniverse.com/forum/showthr ... post495320

brrrrrrraaaaaaaaaaainnnnnnnns

Ok. The guys on TAU dont wanna play, so ill copy across the links later. Zoombie, I get to be overlord of the zombies for the duration of this game, as I am the narrator. However, you can play a guy who is an expert on surviving zombie attacks.

hell play as! I AM THE EXPERT, aside from Max brooks.

Yes but you play a charicter in this game. BTW Plz get MSN as that way i can get advice from you on zombie killing stuff :D

Four or three questions:
ONE: WHAT is Msn?
TWO: Where is MSN?
THree: WHY is MSN?
Four: Why isent their two suns, cause it would be realy cool to live in a binary starsystem rather a single star star system like we are now. But then again life would be VERY different because of the radiation and other killy things that stars tend to put out in large quantety's.

#3. Because Microsoft must create and control all software everywhere

and finally the question I really wanted to answer

#4. Even in a binary star system, Earth would rotate primarily around 1 star. The second star in the system would still be a significant distance away. Alpha Centauri, for example, is a binary system that has a stellar separation that varies between 11 and 35 au. Because of 1/r^2, an average star 10 au out would not have a tremendously major environmental impact. On the other hand, if a very close binary (something on the order of .1 au) were possible, something I doubt, the Earth would only have to be sqrt(2), or about 1.4, times further away to receive the same amount of all types of radiation.

Depending on the distance between the stars compared to the radius of Earth's orbit, the Earth would either rotate around one of them or their center of gravity. And FYI Alpha Centauri is a three star system.

Ok, yes, Alpha Centauri is a ternary system. However, for the purposes of this discussion, I choose to ignore Proxima Centauri. It is way too small (.123 solar masses) and way to far away (13,000 au, or about .2 LY, or for the true astronomers, .06 parsecs) to have any effect upon the habitability of a planet orbiting either of the larger stars in the Alpha Centauri system.

On the contrary if we all lived in a trinary star system, its likely our seasons and day night cycle would kill us.

Besides such a small body as the earth is likely to have an unstable orbit int he presence fo 3 suns wether they're as far apart as you say or not, thus it will either be thrown out fo the system, lunge itno the suns, or be pulled apart.

Or by soem slim chance it'll be caught in a stable orbit

A Binary star stystem COULD be two stars orbiting each other with planets orbiting them. If the stars are too close, then the gravitational forces, radiation output and other energy fizzles will pretty much kill any form of life as we know it. Any life that might evolve under sutch cercemstances would be pretty bizzar. So it couldd either be two stars orbiting each other from very far away, and their solar systems only realy getting close to each other every hundread or so years as the outmost planets got near eachotehr. Th secont type is where the stars are REALY close, but this is inherintly ustable as the stars are prone to well... falling into eachotehr when they get this close. Nova's are sutch an occurence as two clsoe together stars flare when they get to close. Or was that a different thing?

Also planets would be harder to forme with two stars because the gravitantional pulls between the two stars would pull the planitoids apart before they can form well enough.

Because Microsoft must create and control all software everywhere

yes, but what about linux, whitch has a lode of realy cool and spiffy options, and Macintosh, whitch also come with a cool interface and other spiffy options. Those are (supposidly) not controlled by Microshoft, whome i refuse to speel correctly

Microsoft controlling all software everywhere is their mission statement. It does not mean that they will succeed.

Alantai, given the numbers I specified, Proxima would accelerate a planet orbiting Alpha Centauri A or B at
G*M/R^2 = G*.123sm/(13000au)^2 = 7.27810651 ├âÔÇö 10^-10 in some arbitrary units.
The acceleration of earth due to Jupiter at its furthest point from us is
G*M/R^2 = G*.001sm/(6au)^2 = 2.77777778 ├âÔÇö 10^-05 in the same arbitrary units.
This means Jupiter accelerates earth 38,166.215 times faster than a star of Proxima's size and orbit would.

also, for binary Alpha Centauri A and B, Numerical simulations by Paul Weigert at University of Toronto have shown that each star has a "safe zone" about 3 AU in radius in which planets could safely survive for billions of years.

i take off my hat to you, ILMtitan, and your exalent knowleg of intersteller siences in general
