The Universe Seems to Be Stuck in Place by a Strange Quantum Phenomenon
Researchers from the University of Portsmouth have developed a mathematical model suggesting that quantum fields may be more stable than previously thought. The study indicates that quantum fields can become 'locked' in place, potentially preventing the universe from shifting into a different, unstable state.
Why it matters
This research addresses fundamental questions about the long-term stability of the universe and the potential for catastrophic changes in the laws of physics.

Quantum field theory describes invisible quantum fields all around us, producing subatomic vibrations that show up as particles and matter.
These fields tend to seek out the lowest possible energy state, like a marble settling at the bottom of a bowl – and certain fields may have lower to go than they are currently.
In a new study in the Journal of Cosmology and Astroparticle Physics , researchers led by a team from the University of Portsmouth in the UK detail some reassuring discoveries that suggest quantum fields could become effectively locked in place, which could help explain why the Universe has remained stable.
