Scientists have demonstrated the existence of gravity between antimatter and Earth, reaffirming Albert Einstein’s General Theory of Relativity.

It is thought that Isaac Newton's historic work on gravity was inspired by watching an apple fall to Earth from a tree. But for decades, scientists have wondered what would happen to an “anti-apple” made of antimatter - would it fall in the same way if it existed?

Until now, the question has left scientists with an incomplete picture of the Universe's gravitating content.

In a paper published today in Nature, the ALPHA collaboration at CERN’s Antimatter Factory, which includes academics from The University of Manchester, shows that within the precision of their experiment, atoms of antihydrogen – a form of antimatter – fall to Earth in the same way as regular matter.
