Can life exist on other planets without it being organic?

Question

Scientists say that for life to occur, Carbon, Hydrogen,Oxygen and Nitrogen are required. But maybe life can exist without these elements. If so, then a huge number of other planets can bear life too.

Answer 1

Silicon combines with lots of other elements, so it might be remotely possible for life to be based on it. For that matter, we may some day create silicon based life.

However, if you ever lift a CRC Handbook of Chemistry & Physics, you will note that the table of organic molecules is about six times the size of the table of inorganic (all other molecules) combined. That tends to make carbon a really good choice for complex molecules.

Answer 2

Is that said? I hadnt heard that life and water necessarily go hand in hand. It is very possible that on another planet with different elements and environmental factors that a life form could make a stronghold. It could be another chemical in a liquid state that gave rise to life on another planet; to take this even further, one could say that life doesn't necessarily have to be carbon-based like it is here on Earth. "Life finds a way" , I believe is the saying... but thats all that it says. It doesnt say that it must find a way using water! We must keep our minds open to the idea that life is extraordinarily reseilient and persistent, and using these attributes, may have been able to adapt to another way of sustaining themselves. hope this helps

Answer 3

As they say in Star Trek - "It's Life, Jim, but not as we know it."

Under certain conditions, other elements could act as carbon does, say silicon. So, life might arise based on these elements.
That being said, the Earth has had periods of billions of years where it has been at various temperatures and conditions, and non-carbon life forms have not been found in the fossil records. Although perhaps they may not be recognised as such.

Answer 4

That's a bit like asking, "Can a circle exist that has a circumference that is not 3.14 times as long as it's diameter?" Perhaps there can be a circle that is not a circle. But, the definition of a circle is that all circles have this proportion of 3.14 diameters equals the circumference. Life is defined, anyway, not by it's composition, but by it's activities. There are no universal definitions for life.

Answer 5

Likely life will be something similar to what we see.
Probably based on some type of DNA not much different than ours.
Intelligent technological societies will probably parallel our development in many ways.
They may look a lot different but they will think the same way.

Answer 6

In earth we are using chemical reactions in our organic bodies. Other planet's creatures can use nuclear reactions or reaction type that we don't know yet.
But all types must be organic to make a reaction .

Answer 7

we are organic and we consume rganic so we need a planet with organic ,to say the least

Answer 8

it should be a weard plant not a normal one da! it just look the same human cant survie da! you try la.
