What would the universe be like if it had four spatial dimensions instead of three? Experimentalists are starting to explore the physics of higher dimensions with the help of recently developed tricks ...

M-Theory stands as a promising candidate for a unified framework, encapsulating the various superstring theories and positing an 11-dimensional description of nature. Its compactification on ...

Physicists wonder if our universe contains hidden extra dimensions. These dimensions could explain why gravity is so weak. They might be curled up so tightly we cannot see them. High-energy particles ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...
