The ground itself is the barrier between our four-dimensional space and metaspace.

The timegate allows us to open wormholes connecting two openings in four-dimensional space-time.

Each quaternion has four parts, like the co-ordinates of a point in four-dimensional space.

In general relativity, bodies always follow geodesics in four-dimensional space-time.

Every hyper-solid of four-dimensional space has these four axes.

In the absence of matter, these geodesics in four-dimensional space-time correspond to straight lines in threedimensional space.

This regular solid of four-dimensional space consists of sixteen cells, each a regular tetrahedron, thirty-two triangular faces, twenty-four edges and eight vertices.

This would become essential for framing Einstein's relativity theory in four-dimensional space-time (three spatial dimensions with a fourth dimension -time).

So the thing to remember is that the mass of a particle is the "radius" of a shell in four-dimensional space-time.

Every electron, in other words, must be the starting point of a pathway into-anda terminal point out of- four-dimensionalspace.
