What cosmic disasters threaten earth?

The video discusses the potential dangers posed by cosmic events, particularly asteroid impacts, to life on Earth. It highlights the frequency and scale of these events, using historical examples like the 1908 Siberia explosion. The video emphasizes that while these events are rare, they are preventable through mapping and intervention strategies, such as using rockets to alter asteroid paths. The importance of proactive measures to avoid catastrophic impacts is underscored, contrasting our capabilities with those of the dinosaurs.

What is the likelihood of cosmic events posing a threat to life on Earth?

• They are highly probable and occur frequently.

• They are low probability events but can be dangerous.

• They are impossible and never occur.

• They happen every day and are a major concern.

What is the most common cosmic event that can impact Earth?

• Gamma ray bursts

• Solar flares

• Nearby supernovae

• Asteroid impacts

What was the impact of the 1908 Siberian explosion?

• It was a nuclear-sized explosion that devastated a large area.

• It caused a small fire in a forest.

• It had no significant impact.

• It destroyed a city completely.

How can we prevent asteroids from hitting Earth?

• By blowing them up with nuclear weapons.

• By ignoring them as they are harmless.

• By sending astronauts to live on them.

• By mapping their paths and altering their trajectories.

What is the key to preventing asteroid impacts?

• Finding and mapping them early.

• Using nuclear weapons as a last resort.

• Sending a team of oil riggers to destroy them.

• Waiting until they are close to Earth.
