What are the main things that are needed for life to exsist on another planet, or can micro bacteria or whatever just adapt to heat, cold, water, ect, what was on our planet when we first came about?
Mackay1011 said:so for any planet to sustain life of any kind HAS to have carbon, oxygen and water.
cant you have argon carbon and water for example? what's argon anyway lol
BoomBoom said:Saying that oxygen and water are required is redundant since water conains oxygen.
Moridin said:Oxygen might not be needed as well, since there are bacterial life here on Earth that would die in oxygen rich environment. They get their energy from oxidizing sulfur or iron, I think.
Danger said:And just how would they oxidize something if they have no access to oxygen? :tongue:
The basic necessities for life to exist on another planet are water, a source of energy, a stable atmosphere, organic molecules, and favorable temperatures.
While water is essential for most forms of life on Earth, there is a possibility that life could exist on a planet without water, as long as another liquid can serve as a solvent for biochemical reactions.
The source of energy on a planet is crucial for life to exist. This energy can come from various sources, such as sunlight, chemical reactions, or heat from the planet's core. Without a source of energy, life cannot sustain itself.
Yes, it is possible for life to exist on a planet with a different atmosphere than Earth's. The key is that the atmosphere must be stable and contain the necessary gases for life to survive, such as oxygen, carbon dioxide, and nitrogen.
Some factors that could make a planet uninhabitable for life include extreme temperatures, lack of a suitable atmosphere, high levels of radiation, and no source of energy. Other factors such as the planet's size and distance from its star can also affect its habitability.
