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.
-
