I've heard before that Jupiter could've become another star when it was forming however it doesn't have a great enough mass. I'm a scifi writer and was recently speculating about this. If Jupiter had become a second sun in our sky. I would like to know what others' thoughts are on how this would have affected human evolution, and our history. This may be to big of an order for me to ask, but I'd appreciate any in put given. Thanks.

We wouldn't be alive...to say the least...the hydrogen helium cycle would have caused the two forming stars to have nuclear fission going on...forget about existence of Earth...I am talking solar system could not have been born!

May be there would be life in Jupiter's planets ...err moons.

Nope - impossibe. They're all WAY too close for that.

Wow, that sucks. Well, so long that idea.

Many star systems are doubles and a lot even three stars. That does not mean that life cannot form on planets in a single or double orbit of one, but there could be large temperature swings (There was a Lost in Space episode in the first series which demonstrated this.) However it would require that two stars be much further away from each other than the sun and Jupiter are.


Jupiter and Saturn show that the Solar System had a cold formation (a burning sun would have blown lighter gases out of the system in formation). Jupiter is under a thousandth the mass of the sun and failed stars come much bigger :

As humanity's earliest god was the sun, it makes you wonder how two suns would have changed this? You could certainly have periods of eternal daylight, as well as periods when it is too bright as well as dull daylight. It is probable that anything that evolved in such conditions would have to be far more hardy than we are.

If you like imaginative SF on strange environments, try Hal Clement's books.

Maybe with 2 suns our planet would be all tropical. No ice. or maybe with no ice, maybe it would be all ocean.

what tropical? Orleander ... the gravity from two suns would probably collapse the idea of having planets at all ...

Binary systems' stars...interact with each other...and I mean massive expulsions of solar flares...magnetic fields distorted.

Algol...Sirius...binary systems for example...

Actually...I was wrong the presence of a binary star actually improves the chances of formation of habitable planets.

Some planets travel an S orbital...

It does of course depend on how close the stars are to each other.

5AU (distance sun jupiter) Makes them far enough from each other To exclude dragons close binairy models that only happens around super stars or real close stars, altough 5AU is to close remember Jupiter actually formed in closer and then migrated outwards. So earth couldn't have formed, if you would place a sun at jupiter then it would all depend on how massive it was if it was 6% solar mass (the min mass), then earth would experience little trouble neither from heat light or gravity, take in mind that alpha centauri A and B are only 11 AU apart at their closest and those are massive stars +100 and 80% the mass of our sun and any planet in their habitable zone wouldn't be noticable pertrubed by the neigbour star

M*W: Excellent question! Let me propose an astro-theological interpretation.

Micha F. Lindemans states, "Jupiter is the supreme god of the Roman pantheon, called dies pater, "shining father". He is a god of light and sky, and protector of the state and its laws. He is a son of Saturn and brother of Neptune and Juno (who is also his wife). The Romans worshipped him especially as Jupiter Optimus Maximus (all-good, all-powerful). This name refers not only to his rulership over the universe, but also to his function as the god of the state who distributes laws, controls the realm and makes his will known through oracles. His English name is Jove.

He had a temple on the Capitol, together with Juno and Minerva, but he was the most prominent of this Capitoline triad. His temple was not only the most important sanctuary in Rome; it was also the center of political life. Here official offerings were made, treaties were signed and wars were declared, and the triumphant generals of the Roman army came here to give their thanks.

Other titles of Jupiter include: Caelestis (heavenly), Lucetius (of the light), Totans (thunderer), Fulgurator (of the lightning). As Jupiter Victor he led the Roman army to victory. Jupiter is also the protector of the ancient league of Latin cities. His attribute is the lightning bolt and the eagle is both his symbol and his messenger.

Jupiter is completely identical with the Greek Zeus."

Now, with that said, do you see the comparison of Jupiter and god and/or jesus?

Astro-theologically speaking, Jupiter is just another god-myth. There is also some speculation about the NT text where jesus alledgely says, "get thee behind me, Satan." He was talking to Peter, or was it mistranslated as Peter the Jew? Of course, to translate this passage literally, the sun/son as if he could talk was saying to Jupiter, get behind me so you don't destroy my own light. This is the jealous god-myth.

Rereading the bible, OT and NT, there's a lot of astrological symbolism. When the bible is read with this in mind, it becomes pretty understandable as an astrology book.

Current archeological digs propose the bear as the first known divinity.
Even neanderthals had bear shrines.

do you think its cuz they could stand up like man?

do you think its cuz they could stand up like man?
I think it was because they where so very yummy.
And they had nice skins that made excelent hats

Or that they were 7-8 feet tall, were very strong with long, very sharp claws and lived in the forests just beyond the firelight at night.

Those bears where probably omnivores mostly herb eaters and therefore far less dangerous than wolfs for example. I also believe they had the same habitation as man (they where named cave bears).
Then offcourse they were deing out perhaps it give them some collidation

This link (http://news.bbc.co.uk/2/hi/science/nature/4602739.stm) also gives a decend reasons why they should worship cave bears, altough they wouldn't have a clue that this would have happend

First of all, i do not believe in evolution. but for the development of any solar system, theoretically, the two stars' gravitational attraction would have created a binary system. One star would eventually acquire too much mass instantaneously, and give off dangerous cosmic radiation which couldn't be distorted by Earth's magnetic field.

Ok.

Really? Theoretically? Gravitational attraction? Cosmic radiation? Magnetic fields?

That's an awful lot of science for someone who dosen't believe in the simple mechanism of evolution by natural selection - which is a fact. As much as any scientific fact can be a fact.

Forceman. Many of the stars in the universe are in pairs so it is a stable grouping.

When stars acquire mass from another orbiting star, it is often a process involving at least millions of years and maybe billions of years. The only way one star could instantly acquire lots of mass would be to literally swallow the other star, which could be a disaster as in nova/super-nova. Energetic stars (notably BH's) can give off lots of cosmic rays but they are fortunately far enough away that we do not have to worry about them.

As superluminal points out, there is ample factual evidence for evolution. A few hours spent on this site will tell you all you need to know :
