Ryu–Takayanagi conjecture
Ryu and Takayanagi received the Dirac Medal of the ICTP for their insights on quantum entropy in quantum gravity and quantum field theories.

Fuzzball
Computer simulations by an Italian scientific team suggested that gravitational-wave signals could reveal fuzzball-theory-supporting evidence, predicting slower decay rates and 'echoes' from ring oscillations in binary black hole mergers.

Fuzzball
An Italian research team proposed that existing gravitational-wave observatories could potentially detect evidence supporting fuzzball theory through unique attributes of fuzzballs during black hole mergers.
|
| 2018 | A group of four physicists advanced a controversial conjecture suggesting the potential non-existence of a universe compatible with a metastable, positive cosmological constant. |

Kaluza–Klein theory
A research article challenges the theory of gravity leaking into higher dimensions while supporting the shared dimensional nature of electromagnetism and gravity, lending partial credence to Kaluza-Klein theory.

Fuzzball
First direct detection of gravitational waves (event GW150914), marking a significant milestone in gravitational wave astronomy and providing a potential method for testing theoretical models like fuzzball theory.

Kaluza–Klein theory
LHC analysis severely constrains theories with large extra dimensions, providing significant empirical limitations for Kaluza-Klein theory.
