Cosmic strings are wrinkles in the space-time continuum that are left over from the original big bang. These cosmic strings travel, and new research suggests that they leave magnetic fields behind. These magnetic fields then essentially magnetize galaxies. It is believed that almost every substantial object in the universe has some type of magnetic field. And for smaller objects, they form their own magnetic fields from inside. There have even been magnetic fields formed inside nebulas.
Key Takeaways:
- Cosmic Strings are defined as wrinkles that travel through space that were created during the original big bang.
- The idea of cosmic strings became notable in the 1970s, but astronomers haven’t located any.
- Cosmic strings are believed to vibrate, and if they do, the ripples formed would move at the speed of light.
“Smaller objects, like planets and stars, generate their own magnetic fields from dynamo actions inside them, where swirling flows of electrically charged plasma force weak magnetic fields to fold over themselves.”
