Deep dives

The Role of Life in Fire

Fire is a rapid oxidation process that typically requires oxygen, but other gases can also serve as oxidizers in different environments. For instance, fluorine gas can enable combustion, suggesting that fire could potentially exist on other planets with suitable atmospheric conditions. However, there has been no observed evidence of fire anywhere beyond Earth, which emphasizes the unique connection between life and the presence of oxygen in our atmosphere. This relationship illustrates a deeper intertwining between Earth's geology and biology, highlighting how life has shaped the planet's chemistry.
