Does our universe have more than four dimensions -- four spatial dimensions plus time? According to some American scientists, the answer is yes. Their new theory of gravity is challenging Einstein's ...

Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's ...

Braneworld models propose that our four‐dimensional universe is a ‘brane’ residing within a higher-dimensional spacetime, while scalar field theories provide a versatile framework to construct and ...

Did the universe begin with a black hole in a higher-dimensional reality? Depending on your level of cynicism, that question sounds like either an exciting idea or something you might hear from the ...

Gravity might be strong enough to hold our solar system together, but compared to the other three forces of nature it is pitifully weak. Cosmologists think this might be because the universe we can ...
