Space travel: Stephen Hawking and billionaire's plan for laser-propelled nanocraft fleet

The video discusses a futuristic concept of sending nanocrafts to Alpha Centauri using a star chip equipped with a light sail. These nanocrafts would be propelled by a powerful laser array located in the Atacama Desert. The goal is to achieve 20% of the speed of light, allowing the nanocrafts to reach Alpha Centauri in decades, a journey that would take current spacecraft thousands of years.

What is the primary function of the light sail attached to the nanocraft?

• To collect solar energy

• To provide communication with Earth

• To use laser light for propulsion

• To protect the nanocraft from space debris

Where is the laser array that propels the nanocraft potentially located?

• Gobi Desert

• Atacama Desert

• Sahara Desert

• Mojave Desert

What is the power output of the laser array used to propel the nanocraft?

• 10 GW

• 50 GW

• 100 GW

• 200 GW

At what percentage of the speed of light can the nanocraft travel?

• 30%

• 40%

• 20%

• 10%

How long would it take for the nanocraft to reach Alpha Centauri?

• A few decades

• A few millennia

• A few years

• A few centuries
