[MCU] Can you go to the other side of universe using Sling Ring, and if yes then what's the point of Space Stone?

The space stone also allows warping of space that sling rings won't, such as absorbing Iron Man's explosions on Titan and turning them back at him as a beam, collapsing the mirror dimension wall Dr. Strange threw at him and generally allowing the other stones to affect space more generally rather than only their location.

It's unclear whether a skilled user of a Sling Ring could do other feats (like pulling pieces of Titans moon though a portal to throw at someone) but it would certainly take some skill, and may be beyond anyone but the Sorcerer Supreme.
