Dave | R
In geometry, a point is a location in space. We can create a line by stringing an infinite number of points in a certain direction and vice verse.

Dave | R
By stringing an infinite number of lines along a dimension perpendicular to the line, a two-dimensional object called a plane can be obtained. And then if we string an infinite number of planes in either direction, we get three dimensional space.

Is space infinite? | R
You can go around the globe forever and never find the edge. If the universe is like the surface of the earth but maybe in three dimensions instead of two? It wouldn't have an edge but also it wouldn't be infinite.

Leonard Susskind | R
The space itself may be more than three dimensions. But we can't visualize more dimensions. The architecture of the brain itself is evolved in the world of three dimensions. We only describe more dimensions by pure mathematics.

Space | R
A space consists of selected mathematical objects that are treated as points, and selected relationships between these points.

Tom Campbell | R
The assumption that space and time is continuous yields Zeno's paradox. The universe is not created out of continuous space and time.

Zeno's Paradox | R
To get to a point in the geometric space, you have to travel half way to that point and half way to that halfway point and so on. There's no end to the halfway so you can't reach the point.
