Questions & Answers

Q: Can artificial magnetic fields solve space travel radiation issues?

NASA is exploring the idea, but faces power generation challenges due to immense power requirements. Future technologies may enable this solution.

Q: Are supermassive black holes crucial for galaxy stability?

Supermassive black holes are minor contributors to galaxy stability, with dark matter playing a more anchoring role in holding galaxies together.

Q: Can galaxies have multiple black holes?

Yes, through galaxy collisions, supermassive black holes can merge, resulting in multiple black holes in one galaxy.

Q: Is the International Space Station real?

Yes, the ISS exists, observable from Earth, and even with binoculars, it's possible to see its structure passing overhead.

Summary & Key Takeaways

  • Space travel faces radiation challenges due to lack of magnetic fields.

  • Supermassive black holes are not essential for galaxy stability.

  • Possibility of multiple black holes in galaxies due to collisions.
