In defining the word "theory," Merriam-Webster.com specifically identifies the challenges associated with the word: there are two senses of theory which are sometimes troublesome. These are the senses ...

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 ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

Researchers at Aalto University have made a significant stride by developing a novel quantum theory of gravity. This new framework describes gravity in a manner that is consistent with the Standard ...
