Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

The Princeton that Albert Einstein knew in 1933 was sharply divided by the color line; a long-established border—marked by ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

New quantum experiments may settle the century-old Einstein vs Bohr debate, revealing key insights into quantum behaviour.

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

Mars follows a markedly different rhythm from Earth, as a Martian day is roughly 40 minutes longer than an Earth day, while a ...

Particles faster than light could revolutionise our understanding of space, time, and the universe’s fundamental laws.

Time does not pass at the same speed on Earth and the moon; with lower gravity, lunar clocks run faster by around 56 ...

Since the bloodbath of World War I, philosophers have repeatedly grappled with the question: Is war an irrepressible human ...
