Does Dark Matter Cause Extinctions?

The video discusses extinction events occurring every 30 million years, possibly linked to dark matter in the galactic disk affecting comet orbits and causing mass extinctions. It also explores the hypothesis that dark matter could heat Earth's core, leading to volcanic activity. Additionally, the video covers Schultz's star, which passed close to our solar system, potentially disturbing comets in the Oort cloud.

What is the proposed role of dark matter in extinction events?

• It alters comet orbits, leading to impacts on Earth.

• It increases the Earth's gravitational pull.

• It absorbs all light, causing darkness.

• It emits radiation that affects species.

What is the main challenge in studying dark matter?

• It is too bright to observe.

• It changes its form frequently.

• It is only found outside the Milky Way.

• It does not interact with electromagnetic radiation.

How might dark matter influence geological activity on Earth?

• By increasing the Earth's magnetic field.

• By accumulating in the Earth's core and releasing energy.

• By cooling the Earth's core.

• By causing earthquakes directly.

What is the significance of Schultz's star's proximity to our solar system?

• It was visible from Earth.

• It caused a solar eclipse.

• It might have interacted with comets in the Oort cloud.

• It increased the temperature of the sun.

What is the Oort cloud?

• A comet-filled region at the edge of our solar system.

• A region filled with asteroids.

• A cloud of gas surrounding the sun.

• A cluster of stars near the Milky Way's center.
