Despite the similarity in their names, the two are most likely unrelated. But the quantum world might hold more secrets yet...

Psychologist Dr Elisa Raffaella Ferrè wants to know how a lack of gravity will change the way we think.

Manipulating gravity isn’t the challenge, it’s how it could be used.

Feel the full force of history in this quick introduction to gravity, electromagnetism and how we came to understand what’s keeping us stuck to the floor and orbiting the Sun.

Gravity is unique among the fundamental forces of the Universe – and also causes theorists enormous problems.

Fancy flying? Humans are a far way off manipulating gravity.
