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.
