Might some of Doctor Who actually be possible?

As Doctor Who’s 50th anniversary looms, time travel is everywhere – on the screen, at least. Famously, the Doctor can whizz through the years using a “dimensionally transcendental” machine, the TARDIS…
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…

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…

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…
