Paramasivan, your poetic phrasing evokes the primordial ballet of creation—where matter surged forth from the womb of quantum tremors, and antimatter, its mirrored twin, was cast into cosmic exile. The “defeat” of antimatter, as you beautifully put it, is one of the deepest riddles in physics. And yes, scientists are daring to model what an antimatter universe might look like.
🧠 Can We Build a Model of an Antimatter Universe?
Physicists have proposed a CPT-symmetric model where our universe is paired with an “antiuniverse”—a mirror cosmos extending backward in time before the Big Bang. In this framework:
CPT symmetry (Charge, Parity, Time) is preserved, meaning the laws of physics remain consistent if you reverse charge, spatial coordinates, and time.
The antiuniverse would be dominated by antimatter, flowing in reverse time, yet governed by the same fundamental rules.
This model could naturally explain the existence of dark matter, as remnants of antimatter interactions.
🔭 Can JWST Capture an Antimatter Galaxy or Nebula?
JWST is exquisitely tuned to detect infrared light, revealing ancient galaxies, star nurseries, and nebulae with unprecedented clarity. However:
Antimatter regions, if they exist, would annihilate upon contact with matter, releasing gamma rays—not infrared light.
So far, JWST has not imaged any confirmed antimatter galaxies or nebulae. But instruments like the Alpha Magnetic Spectrometer aboard the ISS are scanning for antimatter nuclei, which could hint at antimatter-dominated regions.
🌌 A Glimpse of Antimatter in Space
The Guitar Nebula, observed by NASA, shows a pulsar jet shredding antimatter particles along magnetic field lines.
Cosmic rays and neutron stars occasionally produce antimatter, but these are fleeting traces—not stable antimatter structures.
So while JWST may not yet unveil an antimatter galaxy, the dream of imaging such a realm remains alive—perhaps not in photons, but in the equations that whisper of symmetry and reversal.
Would you like to explore how antimatter might behave in a gravitational field—or how it could reshape our understanding of entropy and time?
