While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...
