During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

Modern physics stands on two pillars: Einstein’s theory of relativity and the Standard Model of particle physics. The theory of relativity encompasses the gravitational force, one of the four ...

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research shows ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Traditionally, physicists have assumed that Einstein’s theory must be modified to fit within the quantum framework. However, UCL researchers propose a striking alternative: a "postquantum theory ...

The mysterious force called Dark Energy, which drives the expansion of the Universe, might be changing in a way that ...

During one such daydream, Einstein experienced what he would later call “the most fortunate thought of my life.” He knew that his 1905 special relativity theory applied only to the ...

Physicists have taken a bold step beyond Einstein's special theory of relativity, proposing an expansion of special ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

Einstein's theory of general relativity predicts gravitational memory, where space-time retains imprints from passing gravitational waves. Researchers are exploring if the cosmic microwave ...
