When Einstein, born 139 years ago last Wednesday, came onto the science scene, physics was in crisis. New ideas were badly needed — it was the perfect moment for a trailblazer.

We know that at the heart of pretty much every galaxy, there is a giant black hole. There is a lot that we know about black holes — and a lot that we don't know.

Three scientists won the prize after a 25-year-long search of the cosmos for gravitational waves — the waving of space — the one test missing for Einstein.

Just as two kids jumping on a trampoline around each other send waves rippling outwards on the fabric, black holes distort space as they orbit around each other.

Carlo Rovelli's new book is a gem: It's full of wonderful analogies and imagery — and is a celebration of the human spirit, in "permanent doubt, the deep source of science."

As Albert Einstein's Theory of General Relativity turns 100, the scientist would surely be pleased with the revolution he started, a source of wonder and inspiration for all.

The Theory of Everything celebrates the spirit of a man who has fought for all of his adult life to uncover the mystery of time.

Few, if any, movies have been this faithful to science and still managed to tell a gripping tale — though some liberties are taken at points.

In taking sides for or against a theory, scientists place their faith on an idea. Marcelo asks what happens when the idea can't be tested or validated. Is it still science?

We don't have all the answers; many big questions hang over the world of theoretical physics. Is this business as usual? Or symptom of a major crisis in our understanding of nature?

Stephen Hawking wants to do away with black holes (as we know them) so he can save the two pillars of modern physics: general relativity and quantum mechanics. At stake is our understanding of the nature of space and time, and how matter affects, and is affected by, both.
