I'm still a newbie in Mathematica. I want to draw a beam of radius of the sphere in $\mathbb{R}^3$ without the surface appearing (look at the attached image). I would like so many to appear that the drawing looks dense but not so many that they overlap too much. Thanks for your help.

Similar to what Ulrich Neumann wrote:

With[{n = 1000, r = 0.01}, 
              Cone[{#, {0, 0, 0}}, r] & /@ SpherePoints[n]}, 
             Background -> Black, Boxed -> False]]

To go further you'd need proper ray tracing. For example, export as POV and run through POV-Ray.

enter image description here


Try SpherePoints[...]

pts = SpherePoints[200];
Graphics3D [{Orange, Line[Map[{{0, 0, 0}, #} &, pts]]},Boxed -> False]
