According to quantum mechanics, our universe is like a Lego set. All matter particles, as well as particles such as light that act as messengers between them, come in discrete blocks of energy. By ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

Albert Einstein’s name is synonymous with “genius,” and his wild hair is a trope of its own for mad scientists and professors in popular culture. Einstein’s discoveries led to modern-day inventions ...

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When high-energy light hits atoms, it knocks electrons loose. This process powers ...

Jim Baggott is a science writer based in Cape Town, South Africa. He is co-author with John Heilbron of Quantum Drama. Quantum mechanics is an extraordinarily successful scientific theory, on which ...

Physicists describe the microscopic world using a weird theory called quantum mechanics. The year 2025 is the International Year of Quantum Science and Technology, celebrating the 100th anniversary of ...

Everyone recognises Albert Einstein, but few realise just how deeply his ideas have shaped the world we live in. Over a hundred years ago, this German-born scientist turned the way we understand space ...
