Einstein vs quantum mechanics … and why he’d be a convert today

Albert Einstein may be most famous for his mass-energy equivalence formula E = mc2, but his work also laid down the foundation for modern quantum mechanics. His analysis of the “spookiness” of quantum…

How to test the twin paradox without using a spaceship

Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein’s Theory of Relativity predicted a century ago, and it is commonly known as “twin…

New theory of general relativity casts doubt on dark matter

Astronomers have been searching for a mysterious substance called “dark matter” since the 1930s. Most scientists still believe it exists, despite many fruitless decades. Now we propose a new theory of…
Albert Einstein was considered to be a ‘lone genius’ – but this was not the case, and it’s certainly not the norm. Albert Einstein was considered to be a ‘lone genius’ – but this was not the case, and it’s certainly not the norm. tsweden

Einstein to Weinstein: the lone genius is an exception to the rule

Developing a Theory of Everything is physics' Holy Grail. So could it have been completed in recent weeks? And by an outsider, working alone? American mathematical physicist-turned-hedge-fund-consultant…
Remember the Theory of Relativity sceptics? As with the Einstein debate, the modern climate debate is based on politics and strawmen, not facts and details.

Nature v technology: climate ‘belief’ is politics, not science

It is hard to imagine a scientific breakthrough more abstract and less politically contentious than Einstein’s general theory of relativity. Yet in Weimar Germany in the 1920s it attracted fierce controversy…

Expand into 2013 by toasting 100 years of modern cosmology

As 2012 comes to a close and you toast the New Year, be sure to also raise a glass to one Vesto Melvin Slipher. My intent is to describe what Slipher did 100 years ago in Flagstaff, Arizona and why this…

Testing the theory: taking Einstein to primary schools

School students today are taught physics based on obsolete theories and outmoded ways of thinking. Instead of the truth, most learn a naive simplification - the 300 year-old Newtonian physics, itself based…

Rippling space-time: what science could do with Einstein’s gravitational waves

In my previous article we discussed the “who, what, when, where and how” of the worldwide gravitational wave detection effort. The observant observer will have noticed we’re still missing the “why”. Why…

Rippling space-time: how to catch Einstein’s gravitational waves

Albert Einstein made an executive decision to revolutionise our understanding of gravity in a paper published in 1916. Nearly 100 years on, a key prediction of Einstein’s theory has eluded direct detection…

Explainer: gravity

I have spent almost 40 years trying to detect gravity waves. When I started there were just a few of us working away in university labs. Today 1,000 physicists working with billion-dollar observatories…

Is life on Earth due to a quirk in the laws of physics?

A radical discovery by my colleagues and I – reported this week in Physical Review Letters – could help explain why it was possible for life (at least as we know it) to develop on Earth, but not in other…

Explainer: Einstein’s Theory of General Relativity

It’s the year 2100. You wake up alone in a small, windowless room. The only other thing in the room is a small ball. Maybe the room is located in your city, but maybe it’s inside that new spaceship everyone’s…

Gravity waves, scientists wave back: squeezing light beyond quantum limit

Detecting gravity waves is a major goal for astrophysicists. We know they should be there, but we haven’t found them yet. But today we are one step closer. By literally squeezing light on a quantum level…

An eye to the future of astronomy … a cosmic pick ‘n’ mix

Predicting the future is a mug’s game. When I reflect back on what we thought we knew at the start of my research career in the mid-1990s, I sound like a wizened octogenarian, recalling a simpler time…

Adventures in the dark side of cosmology

In questioning the fundamental nature of the universe, cosmology regularly grabs the public’s attention. But in an era in which we are observing deeper and more widely than ever before, our knowledge of…
