If we are to believe in the big bang theory then it stands to reason that all planets should have life.

Question

the bang, the centrifugal forces, every piece of matter would have been blown out into space, away from the heat of the sun , frozen, and then still in the suns gravitational pull, slowly cool . they all have the same genesis, so if we have' life' then all suppose to have the same.

Answer 1

hmm...you dont understand the universe or the big bang theory. the big bang is the origin of the universe, not of the solar system. there are an average of 100 billion of stars in each galaxy. there are atleast 150 billion galaxies in the universe. the big bang is the origin of all those. it has nothing to do with the solar system.

life depends on water. water depends on distance from the sun. earth is the only planet in this solar system that is the correct distance from the sun have liquid water, and therefore to support life.

Um...no it doesn't. What makes you think it does?

>the bang, the centrifugal forces, every piece of matter would have been blown out into space, away from the heat of the sun

You seem to be misinformed. The Big Bang was extremely large in scale, much larger than our Solar System. In addition, it ocurred more than eight billion years before the Sun formed.

It HAS been brought up that the Big Bang should have sent all matter and energy flying out uniformly across the Universe, failing to result in any stars or planets at all. However, it is generally accepted that random quantum effects caused some unevenness in the structure of the very early Universe, which then grew larger due to the Butterfly Effect and eventually produced stars, planets, galaxies and just about every other object we see in the Universe. The quantum perturbations do NOT in any way dictate that life is necessarily common in the Universe, despite the fact that any life that does exist in the Universe (including our own) was, indirectly, caused by them.

Answer 3

the big bang has nothing to do with how or why life evolved... the big bang is just the creator of the early universe... since then, multiple things have changed the universe since it was born... namely stars going supernova and creating heavier elements essiential to life...

life is believed to of began when a comet deposited bio-organic type materials into the planet -OR- life started when just all the right elements were in water and lightning struck it, fusing the elements together and making amino acid, the building block for life... and it WAS proven this is a distinct possibility, just by putting the suspected elements into water and striking the water with extremely high voltage shocks....  

Answer 4

They all could have some "Life"-Form...!!

Answer 5

non sequitur.  Logical leap.  You assume all conditions are identical for all planets, and this is not correct.  Proof? compare earth with jupiter for a start.

Also ignores the role, as with any reaction, of random events in the formation of life (whatever life is).

It may be that the odds of life coming into existence, even under optimal conditions for its generation, is largely unfavored.

Your statement assumes that the reactions leading to life formation are generally favored.

Consider the dissociation reaction of a strong acid: in general thinking we consider that all of the molecule dissociates, but in reality there is always a very very small amount of non-dissociated compound that is in equilibrium.  It may be that the reaction chain leading to life formation is heavily favored in the other way (the no life is formed direction).  Even in this situation, there will be rare cases of life being formed.

Faulty conclusion based on faulty premise.

Answer 6

Despite logical fallacies, i agree with your conclusion.

The material and events that led to life on Earth seems to be common in the Universe.  The elements needed for life include hydrogen, oxygen, nitrogen and carbon.  These are common.   Water is also common. Various precursor biological molecules are common.

Life formed on Earth about as soon as it was possible.  So, it seems likely that getting life started is fairly likely for a planet.

Something like half of all stars have planets. There are hundreds of billions of stars in our galaxy.  There are at least hundreds of billions of galaxies in the visible Universe.  The visible Universe is a tiny fraction of the minimum size that the full Universe must be.

It seems very unlikely that we are the only life forms, or intelligent life forms in the Universe.  I expect thousands of intelligent life forms in our galaxy alone.

Answer 7

Yes, there's me.
