Einstein's big idea was that really heavy objects like planets, or really fast-moving ones, can distort space-time. It's a bit like the taut fabric of a trampoline: if you put a heavy weight on it, the fabric bows and curves. Any other objects will then roll down the sheet towards the object. This, according to Einstein, is why gravity pulls objects towards each other.

As the closest planet to the sun, Mercury experiences much bigger distortions than any of the other planets.  The equations of general relativity describe how this warped space-time should affect Mercury's orbit, and predict the planet's position down to a tee.

But despite this success, general relativity isn't a theory of everything, any more than Newton's theories were. Just as Newton's theory didn't work for really massive objects, Einstein's didn't work on the very small.

Once you start looking at tiny things like atoms, matter starts to behave very oddly indeed.

Up until the late 19th century, the atom was thought to be the smallest unit of matter. Coming from the Greek atomos meaning "indivisible", the atom by its very definition was not supposed to be able to be divided into smaller particles.

But in the 1870s, scientists found particles that were almost 2000 times lighter than atoms.

Scientists have found ways to divide matter smaller and smaller

By weighing light rays in a vacuum tube, they found extraordinarily light, negatively-charged particles. This was the first discovery of a subatomic particle: the electron.

In the next half-century scientists discovered that the atom had a nucleus hub, which the electrons buzzed around. This hub – which was by far the heaviest part of the atom – was made up of two types of subatomic particles: neutrons, which are neutrally charged and protons, which are positively charged.

But it didn't stop there. Since this time, scientists have found ways to divide matter smaller and smaller, continuing to redefine our notion of fundamental particles. By the 1960s, scientists had found dozens of elementary particles, drawing up a long list known as the particle zoo.

As we understand it today, of the three components of an atom, electrons are the only fundamental particles. Neutrons and protons can be divided further into teeny, tiny particles called "quarks".

Einstein never really believed in quantum theory

These subatomic particles were governed by an entirely different set of laws than those governing big objects like trees or planets.  And these new laws – which were far less predictable - threw a spanner in the works.

In quantum physics, particles don't have defined locations: their whereabouts is a bit fuzzy.  All we can say is that each particle has a certain probability of being in each location. This means the world is a fundamentally uncertain place.

This may all seem very unfathomable and far-out. All we can say is, it's not just you that feels that way. The physicist Richard Feynman, an expert on the quantum, once said: "I think I can safely say that no one understands quantum mechanics."

Einstein was also disturbed by the fuzziness of quantum mechanics. "Despite having instigated it, Einstein never really believed in quantum theory," says Barrow.

All the same, for their respective domains – the big and the small – both general relativity and quantum mechanics have proven, time and time again, to be tremendously accurate.
