Are Cosmic Strings Cracks in the Universe?
PBS Space Time・2 minutes read
Boiling water before freezing creates clear ice cubes by preventing imperfections, similar to how cosmic strings formed from imperfect freezing of quantum fields after the Big Bang in the universe. Cosmic strings, incredibly thin yet high-energy structures, can be detected through gravitational lensing and may offer insights into string theory and the universe's origins.
Insights
- Boiling water before freezing helps create clear ice cubes by removing dissolved gases and ensuring uniform freezing, preventing imperfections.
- Cosmic strings, formed from phase transitions in quantum fields after the Big Bang, resemble thin but energy-dense vortexes in space, with potential implications for understanding the universe's structure and evolution.

"Formation and Detection of Cosmic Strings"
- To create clear ice cubes for drinks, boil water to release dissolved gases and ensure freezing extends through the cube from a single surface to prevent imperfections.
- The universe is compared to a gigantic ice cube, with cosmic strings being topological defects formed from imperfect freezing of quantum fields after the Big Bang.
- Phase transitions in quantum fields during the early universe led to the merging of force-carrying fields and the formation of cosmic strings.
- Quantum fields are numerical properties of space that can oscillate, with the Higgs field undergoing vacuum decay and forming cosmic strings due to changes in energy.
- The Higgs field developed a bump in its potential curve as the universe cooled, leading to the formation of cosmic strings resembling vortexes in 3-D space.
- Cosmic strings are incredibly thin but hold vast energy, with the largest loops having the mass of the planet Mars for every 100 meters of length.
- Cosmic strings move and vibrate under tension, leading to collisions and the formation of smaller loops that eventually decay due to shedding energy.
- Methods to detect cosmic strings include observing gravitational waves emitted by them and using gravitational lensing to spot their effects on background light sources.
- Cosmic superstrings, potentially stretched from string theory filaments during the inflationary epoch, behave similarly to cosmic strings but have differences like forming junctions.
- Distinguishing between cosmic strings and cosmic superstrings may be possible through observing specific gravitational lensing patterns or junction formations, providing evidence for string theory.
