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 ...

Recent scientific discussions suggest that the fourth dimension might be concealed within our everyday perception of reality, challenging conventional views of space and time. This idea intersects ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of ...

A new study explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...
