the main issue addressed in the ff. blog entry is "Physicists create a baby wormhole in the laboratory" but my particular interest is...
-------
(on Maldacena's conjecture)
There are quantum field theories (theories of gluons, quark-like particles, and some additional friends, but with no gravity, in a world with three space dimensions and one time dimension) that are exactly equivalent to supersymmetric string theory (a theory with nine space dimensions and one time dimension, with an infinite set of particles and fields, and with quantum gravity) where the strings are moving on a uniformly 9+1 dimensional curved space.

i've been reading Maldacena's conjecture since 2015 i think, maybe this time i'd be able to get some clues on what i am reading because i have a key now to decipher Maldacena's paper but there are pre-requisite subjects you know, seriously

wormholes? you can start with understanding the geometry resulting from rewriting Schwarzschild metric in isotropic coordinates and do some digging regarding isometries that would involve the famous Einstein-Rosen bridge... some basic discussions you can find on pp. 24-26, Townsend. https://arxiv.org/abs/gr-qc/9707012... my concern here though is on conformal compactification pp. 40 but since today is an mwfsat day i can dwell on it tomorrow
and... anyway
congratulations! to Maldacena conjecture it's 25 years now since its pre-print submission in November 1997 still standing as a very useful tool
