The theoretical physicist and best-selling author finds inspiration in politics and philosophy for rethinking space and time.

In the words of Dr. Lawrence M. Krauss, space and time cannot contain the fundamental laws of physics because they generate ...

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 ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...

It's a plot device beloved by science fiction: our entire universe might be a simulation running on some advanced ...

While a quantum computer could factor a 2048-bit RSA key in less than a week with fewer than a million qubits, there are ...

But today, especially with regard to modern technical applications of quantum physics, we are often faced with the challenge of describing quantum systems that consist of many particles. "To describe ...

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 ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...
