Nadia Bahjat-Abbas is a mature student working on one of the hardest problems of modern physics. Find out more in this video.
The holy grail for 21st century physics is to produce a unified theory of everything — M-theory is a prime candidate. Find out more in this video.
Masaki Shigemori works on black holes and spacetime bubbles. Find out more in this video.
A quick tour to some of Hawking's most significant achievements.
Since the detection of gravitational waves we know for sure that black holes do exist. To understand what really goes on inside them we need a new theory.
Can we define an event without reference to space and time? And why would this be useful? Laura Mersini-Houghton explains.
Physicists have discovered evidence that our Universe might be a giant hologram.
With all the trouble caused by quantum mechanics and people's attempt to construct a theory of everything, we might be better off defining an event without reference to time and space. It's easier than you might think!
The strange theory of quantum mechanics has turned our conception of reality on its head. This article explores how things become fuzzy in the microscopic world and what this means for our understanding of events.
