Questions & Answers

Q: Can dark matter fall into black holes?

Dark matter is attracted to black holes due to gravity, becoming part of the black hole's mass once inside the event horizon.

Q: Are magneto spheres important for exoplanet habitability?

Magneto spheres shield planets from harmful radiation, crucial for surface life forms to survive, and astronomers are actively researching their existence.

Q: What is the net mass energy of Earth, considering meteor impacts and atmosphere loss?

Earth's mass stays relatively constant as meteor impacts and atmospheric loss balance each other out over time.

Q: How do laser arrays work in space propulsion?

Laser arrays can provide thrust to solar sails, allowing for accelerated motion through controlled photon emissions.

Summary & Key Takeaways

• Dark matter can be attracted to black holes, but once inside the event horizon, it becomes part of the black hole.

• Magneto spheres around exoplanets are crucial for habitability and protection from radiation.

• Fraser shares his favorite sci-fi picks and discusses the feasibility of laser arrays for space propulsion.
