Let’s be clear: at this point, aliens inhabiting any dimension are purely hypothetical, let alone the fourth dimension. But that fact hasn’t stopped scientists and philosophers from exploring ...

The sheer fact we can conceive of higher dimensions than four within our mind, within our mathematics, is a gift… It’s ...

Or do we? String theorists believe our world encompasses more than three dimensions. Without experiential evidence, the mathematical theory of space and time as a fourth dimension has remained ...

Life may already exist in another dimension that we may not be equipped to see. That “life” may exist in the fourth dimension, a space that lies beyond our visible universe, operating in ways ...

POSSIBLY the question, What is the fourth dimension? may admit of an indefinite number of answers. I prefer, therefore, in proposing to consider Time as a fourth dimension of our existence ...

Space and time are now woven into a coexisting fabric. That is to say, we truly live in a four-dimensional universe. Space and time alone cease to exist; only the union of those dimensions remains.

This is difficult to visualize, as we can only perceive the world around us as a three-dimensional space, and even more challenging to measure. An example of a four-dimensional object is the ...

The central objects of study in topology are spaces called manifolds, which look flat when you zoom in on them. The surface of a sphere, for instance, is a two-dimensional manifold. Topologists ...
