Life Elsewhere in the Universe

Exobiology

Also known as astrobiology, is the study of life in space, combining aspects of astronomy, biology and geology. It is focused primarily on the study of the origin, distribution and evolution of life.

Some major astrobiological research topics include:

• What is life?
• How did life arise on Earth?
• What kind of environments can life tolerate?
• How can we determine if life exists on other planets?
• How often can we expect to find complex life?
• What will life consist of on other planets?
• Will it be DNA/Carbon based or based on something else?
• What will it look like?

Is there alien life?



First allow us make a few assumptions:

• That there is an infinite amount of stars in the universe, only a few billions could be seen through our powerful telescopes.
  
• Our universe is currently in the "child" stage, the Stelliferous Era. Even today, new galaxies are still being born.
• Time is relative, not constant. The flow of time is different for everyone, and for every place.
• Since the universe is vast, there should be at least some simple form of life; plants and animals.
• Among these primitive life forms, some should have evolved to be intelligent, in aspects of communication, logic, culture, etc.
  

Given the statistics, it's very probable that we could find alien life. However, we are searching for intelligent alien life, which is a whole new level. It's possible we may not succeed in our lifetime. Something for future generations.
