Another argument that we likely start small

In a number of recent posts, I argued that mid-sized objects like ourselves start microscopic. All my arguments so far relied on relativity. Here is one that doesn’t.

1. Biological entities are unlikely to have a perfectly flat macroscopic geometrical face (biological things tend to be rounded, rough, pointy, but not perfectly flat).

2. We are four-dimensional.

3. We are biological entities.

4. If we don’t start microscopic and we are four-dimensional, then we have a perfectly flat macroscopic geometrical face at our temporal beginning.

5. So, probably, we start microscopic.

Why the restriction to macroscopic faces? Two reasons. First, if space is discrete and grid-like, then it may be that all objects have perfectly flat sides at the grid-spacing level. Second, if we are made of point particles, then our geometry likely includes perfectly flat triangles between three outer point particles.
