space-time

What if it destroyed the “space-time continuum,” whatever that meant?

The cosmic crash, now known as GW231123, was detected by the LIGO-Virgo-KAGRA observatories, which measure gravitational waves -- the ripples in space-time produced by massive celestial motions.

Gravitational waves are tiny ripples in space-time that occur when massive celestial objects crash or merge.

Albert Einstein expanded on this in 1916, describing gravitational waves as ripples in the fabric of space-time in his general theory of relativity.

These QFTs, with their simplified space-time symmetry, serve as a laboratory environment, as they resemble real physical systems of subatomic particles but have certain mathematical properties that facilitate calculations.
