Stephen Hawking addressing Royal Society

The video explores the possibility of intelligent life in the universe, highlighting recent experiments that suggest life may be common due to the abundance of organic molecules. However, the evolution of technological intelligence is rare and fragile, as evidenced by Earth's history. It took 500 million years for life to evolve and 2.5 billion years for multi-celled organisms to develop, with technological intelligence appearing only once. This rarity suggests that while life might be common, intelligent life is not.

What recent developments have influenced our understanding of intelligent life in the universe?

• The discovery of new planets

• The launch of the Hubble Space Telescope

• The findings of the Hitler mission

• The invention of the radio telescope

Why is it considered likely that life exists elsewhere in the universe?

• Due to the presence of water on Mars

• Because of the abundance of organic molecules

• Due to the vast number of galaxies

• Because of the discovery of intelligent signals

How long did it take for life to evolve from the earliest cells to multi-celled animals on Earth?

• 1 billion years

• 500 million years

• 2.5 billion years

• 3 billion years

What is suggested about the occurrence of technological intelligence?

• It is common across the universe

• It has appeared multiple times on Earth

• It is a rare phenomenon

• It is inevitable in all life forms

What does the video suggest about the nature of intelligence?

• It is robust and enduring

• It is fragile and prone to self-destruction

• It is always evolving

• It is unique to Earth
