The idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of ...

The modern scientific world prides itself on precision, empirical rigour, and the pursuit of measurable truth. Yet, some of its most revolutionary discoveries—particularly in quantum physics—have ...

The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

I have long been fascinated by the strong attraction many people feel toward quantum field theory as a way to explain extraordinary experiences. As a psychiatrist interested in coincidences and the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

The many worlds interpretation (MWI) of quantum mechanics, proposed by Hugh Everett in 1957, posits that reality consists of ...
