In your mind.
If you need help finding the door try some good fiction. Hitchhikers guide to the galaxy can pull you into another world, so can most of R.A. Salvatore's work. If all else fails read the Hobbit. or you could stop being such an idiot and work it out
yes, it is theoretically possible to create links to distant parts or different times in our own universe, or connect to any one of the infinite possible universes that exist at 90 degree angles to our own, in the 6th dimension. the problem for humans is that the energy required to create and maintain this link is unavailable at our current understanding of engineering and physics.
no. a portal is like a gateway. an astral plane is more like another world.
In the real world sadly that's impossible. In the show, there's the movie "Equestria Girls" of which Twilight travels (by portal) to another world where they are human, and there is a portal that stays open for 3 moons, back to Equestria. So in that way, yes there is that portal.
Nobody has managed to do this yet. If you figure out a way, you'll be a billionaire!

Bringing a Portal Gun then Portalling them to another dimensions!
There is no portal, as the mushroom kingdom is fictional. Sorry :(
A portal.
To use a portal you right-click on the portal.
If the world is getting smaller why do they keep raising portal rates.
The only gun there is on portal 2 is the portal gun which creates the portals. You shoot a portal on white surface, and shoot another portal on a white surface, and you can move yourself and objects through these portals.

In language a door can be considered a synonym for portal. If an individual can open a door, then in the same context an individual can open a portal. A portal is simply a gateway, or entry-point, to another location.
