Asteroid Detection and Deflection Methods

The video discusses the threat of asteroids on a collision course with Earth, highlighting past impact events like Chicxulub and Chelyabinsk. It explores detection methods using telescopes and the proposed Sentinel spacecraft. Various deflection strategies are considered, including rockets, gravity tugs, and laser bees. The video concludes with a call to action, emphasizing the importance of preparedness against asteroid threats.

What was the significant discovery related to the extinction of dinosaurs?

• A new species of dinosaur

• A large crater in Mexico

• A meteorite in Russia

• A fossilized dinosaur brain

What is the potential impact of an asteroid that is 100 meters in diameter?

• It could destroy a continent

• It could destroy a city

• It could destroy the entire planet

• It could destroy a country

What tool is primarily used to detect asteroids?

• Radars

• Telescopes

• Microscopes

• Satellites

What is the main challenge in detecting asteroids?

• Their speed

• Their size

• Their color

• Their distance from Earth

What is one proposed method to change an asteroid's trajectory?

• Using a giant magnet

• Launching a rocket to hit it

• Using a giant net

• Building a wall in space

What is a potential problem with using a rocket to deflect an asteroid?

• It could change the asteroid's color

• It could break the asteroid into smaller pieces

• It might miss the asteroid

• It could speed up the asteroid

What is the concept of 'Laser Bees' in asteroid deflection?

• Bees that carry the asteroid away

• Lasers that vaporize part of the asteroid

• Lasers that cut the asteroid into pieces

• A swarm of bees that push the asteroid

Why is it important to have multiple laser spacecraft in the 'Laser Bees' method?

• To make the process faster

• To increase the power of the lasers

• To ensure coverage if one fails

• To confuse the asteroid

What is the significance of the asteroid's shape in the deflection process?

• It influences the asteroid's temperature

• It changes the asteroid's color
