According to many of these theories, if extra dimensions do exist, gravitational waves would "leak" into those dimensions, causing the waves to weaken as they made their way across the universe.

we might soon discover that the fabric of space-time consists of many more dimensions than we ever dreamed. Extra dimensions promise to solve many of current particle theory's nagging problems. They ...

We experience three spatial dimensions in nature: length, width and height. In addition, we perceive time as a fourth dimension. But some theoretical physicists have speculated that “extra” spatial ...

They cannot explain many of the things we observe in the universe, so many physicists believe we are missing something—and that something could be the presence of extra dimensions. If scientists ...

String theorists are betting that extra dimensions do indeed exist; in fact, the equations that describe superstring theory require a universe with no fewer than 10 dimensions. But even physicists ...

Some theories suggest there could be many more dimensions that we're unaware of, mostly because they're imperceptibly tiny. Now, Japanese researchers have taken the search for extra dimensions ...

Despite decades of experimental searches, however, there has yet to be concrete evidence of these extra dimensions. Now, a ...

New directions – the possibility of extra hidden dimensions is stimulating both physicists and artists. (Courtesy: Richard Deacon) The possibility of extra dimensions, beyond the three dimensions of ...

As fantastic as extra dimensions of space sound, they might really exist. From the relative weakness of gravity to the deep affinity among seemingly distinct particles and forces, various ...
