Spaces in the command are not relevant.  You are calling yourself
recursively, in a subshell (which requires a fork), with no limit.
Eventually you will have launched so many processes that the system
crashes (or does other bad things), unless you hit a configured resource
limit first.

What you have written is a thing we call a "fork bomb".  Don't do it.
