Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

In an effort to solve the riddle of why we have subjective conciousness, scientists have develop myriad theories, including ones involving the quantum realm. A new theory suggests that consciousness ...

The year 2025 marks the 100th anniversary of the birth of quantum mechanics. In the century since the field’s inception, scientists and engineers have used quantum mechanics to create technologies ...

Computer science, at its most fundamental, is all about inputs and outputs. Consider the simple case of multiplying two numbers on a pocket calculator. You punch in some inputs — the specific numbers ...

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
