First, real object teleportation has happened many times in the past and even documented within the 2004 U.S. Air Force Teleportation Report by Eric Davis, PhD. NASA will never find human teleportation because they are looking in the wrong place.
Star Trek teleportation is definitely science fiction; it violates many scientific laws. But is real object teleportation scenario possible? Not only possible; I will postulate it is a natural phenomenon, meaning it happens in nature. So what proof do we have of this natural phenomenon?
There exists many experiments conducted for other objectives in which teleportation happened. It happens in tornadoes, happening many triangle areas in the world (two popular Dragon & Bermuda). Many time travel scenarios are really teleportation. Keep in mind it only takes one to make teleportation a reality. Probably 'that one' is suggested in the U.S. Air Force Report.
As for interstellar travel at light speed with the capability to stop on a dime, teleportation offers that scenario also.
I have applied for one patent to teleport objects, including humans, and working on my second patent for a propulsion system to transfer objects through space at light speed based upon teleportation. Teleportation transfers objects from Point A to Point B instantaneously, just like entanglement transfers information. Teleportation requires technology to be at both points to make the transfer.
