Are the Space-Time Barrier and Flying Thunder God Technique similar to one another?

Question

I came across the difference between the Flying Thunder God Technique and Obito's Kamui Technique Transportation Technique, here.

But what I am struck with the fact that Fourth Hokage used a Space-Time Barrier tecnique to teleport Nine-Tail's Tailed Beast Ball. So my questions are:

• Is Space-Time Barrier similar to Flying Thunder God Technique?
• Is it used to transport things using Teleportation Technique?

Answer 1

a) Jikukan kekkai similar to Flying Thunder God Technique?

Yes, it is derived from "Flying Thunder God Technique", Space–Time Barrier.

b) Is it used to transport things using Teleportation Technique?

This barrier technique incorporates the use of the "Flying Thunder God" formula as well as a unique set of hand seals to erect a barrier capable of warping away anything which comes in contact with it.
