Calabi-Yau manifold: a proposed structure of extra dimensions of space in string theory.
Good questions guide good science, but that doesn’t mean we know where we’ll end up.
From string theory to observations, the multiverse theory is far from safe.

Some physicists believe we could one day find evidence of other universes.
What if the being responsible for creating our world wasn’t God, but some far lesser, far more fallible being like a scientist or video game designer?
Wolfram Physics Project
Mathematical maverick Stephen Wolfram’s latest ambitious project calls on members of the public to help him find the rules that control the world.
Galaxy history revealed by the Hubble Space Telescope.
From a mysterious energy of empty space to parallel universes, cosmology’s view of ‘nothing’ is anything but boring.
Hawking at the University of Cambridge.
Hawking wasn’t able to give his students a gentle introduction, but he did provide a lot of inspiration and support.
Stephen Hawking thought a form of string theory could be our best bet for a ‘theory of everything’.

After the triumph of general relativity, Albert Einstein spent the rest of his life chasing a unified theory, which eluded him right up until the end.
The fathers of modern physics, including Einstein, Millikan, Planck and others, in debate.
Physicists are working hard to unite Einstein’s theory of relativity with quantum mechanics. It’s no easy task.
Can the arts be a bridge to other worlds?
Is a novella published 130 years ago our best bet for explaining the worlds of 4D and beyond?
Scientists are searching for collisions between different ‘universe bubbles’ in the cosmic microwave background.
The idea that our universe is just one in a ‘multiverse’ of parallel universes is increasingly gathering attention from cosmologists. But can we ever test the theory?
Black holes don’t deserve their bad reputation, says study.
Black holes may not be the ferocious killers they are made out to be, suggests study.
The Big Bang theory and the existence of God are ideas often grappled with when thinking about how the universe was created.
Last week’s Global Atheist Convention and debates between prominent atheists and theologians in the Australian media has seen arguments about the existence of God getting a thorough airing. In my view…
A universe composed differently could still support complex life.
Welcome to Peer Review, a series in which we ask leading academics to review books written by people working in the same field. Here Geraint Lewis, Professor of Astrophysics at the University of Sydney…
How long’s a piece of string? You may want to sit down for a minute.
String theory entered the public arena in 1988 when a BBC radio series Desperately Seeking Superstrings was broadcast. Thanks to good marketing and its inherently curious name and features, it’s now part…
We’ve got the time, if you’ve got the theory.
By now we’re used to the idea that the world has four dimensions: three spatial and one temporal. But what if there were a fifth dimension – what would that dimension look like, and how would it relate…
