Peter Plichta writes that:
"A concept of 4-dimensional space has been used by scientists since Einstein. This is arrived at by adding the three dimensions familiar to us from sense experience (length, width and height) and the single dimension of time (the Space-Time Continuum). This concept was fiercely disputed by mathematicians from the very start, since space around a three-dimensional body (cm3) must logically be four dimensional (cm4)".
Can someone explain to me why space around a 3D body must be 4D.
