How can we imagine the 4th dimension?
But I've heard that there are other ways to imagine it, like a tesseract. How does that work?
Ah, yes. A tesseract is a geometrical figure that exists in four dimensions. It is like a cube, but with an extra dimension. So, we can imagine it as a 4D object that we can only see as a 3D projection, much like we can only see a cube as a 2D projection.
