vacuum as a state doesn't exist...only theoretical in calculations...
True. The properties a vacuum under field theory are considered to be equivalent to the ground state of the measured problem. So all fields have a basal state (actually the the Higgs field has a non-zero value, at 246 GeV !), including string theory vacuum, featuring non-scalar condensates.

to believe in teleportation without physical transportation is like to believe in supranatural forces
You still did not understand my last explanation. Matter is not teleported. It's "information", in the shape of a particle's quantum state. When 2 entangled particles are far appart, information created at one's location is instantly teleported to the entangled particle's location, far appart. That's the only "teleportation" that occurs. It's Einstein's "spooky action at a distance".

And I did understand your previous explanation of particle collision in space. It's just not necessarily correct. Light doesn't propagate through space only by bouncing off hydrogen atoms (it doesn't need to bounce on anything at all, for that matter, it can and does travel through "empty" space just fine). That may very likely be the case in hydrogen rich environments such as interstellar clouds, but unlikely in the geospace. On the geocorona on Earth’s dayside, at 60'000km altitude, there's a hydrogen density of 70 atoms per cm3 (it's denser than on the nightside, as they're compressed by sunlight on the dayside). At the moon's distance there's about 0.2 atoms per cm3. The chances of the photons bouncing off hydrogen atoms are quite low.
