Sometimes, the simplest explanation is the best one," Professor Gupta said. "Maybe the universe’s biggest secrets are just ...

Up to now, humans have only been able to observe four dimensions in the universe – height, length, width and time. But beyond these dimensions, collectively known as 'spacetime', there may be more ...

In the moments before the Big Bang, our universe was a hot, dense, and extremely high-energy place. That all changed when the universe exploded 13.8 billion years ago. Rapid inflation divided a single ...

A unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other fundamental forces (electromagnetic, weak, and strong) described using quantum field ...

Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity ...

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 Standard Model of Particle Physics accounts for four fundamental forces—strong, weak, electromagnetism, and gravity—but for decades, scientists have wondered if an elusive fifth force might be at ...
