Illusions of Grandeur?

Posted on May 15, 2012 by PlatoHagel

Illusions of Gravity Three spatial dimensions are visible all around us–up/down, left/right, forward/backward. Add time to the mix, and the result is a four-dimensional blending of space and time known as spacetime. Thus, we live in a four-dimensional universe. Or … Continue reading →

Stringy Geometry

Posted on March 8, 2008 by PlatoHagel

fancier way of saying that is that in general, it’s okay to model the space around us using the Euclidean metric. But the Euclidean model stops working when gravity becomes strong, as we’ll see later. The Euclidean model for space … Continue reading →
