I would hate to think a friend also but people can have a hidden psych issue that's not necessaryly evil but a strange impulse control.
I have a neighbor that will put things on my cars window's wether it's tape or a chicken bone. He will also turn on my lights if I happen to leave my car unlocked just to kill my battery. I don't consider him a friend though more of a neighbor? I really don't know were i'm going with this, but you never know?:undecided:
The fact is he did not specified what he mean by "portals". So, what if he thought about an automatic door? This is why I gave him an answer what I gave in the first post as these are the most "real" portals available with current technology. Not to mention that depths of our brains might be opened by various ways - one my friend compared my latest artwork to LSD effects for example - so these are portals as well.
But as we discussed the worm holes - all that stuff is much more complicated and without kind of exotic matter we cannot keep the worm hole open for enough time to allow anything macroscopic to go through. However we might take worm holes (supposed to be) naturally created in quantum foam and enlarge them for some time. But we need that exotic matter for that and noone knows where to find some.
Nothing to thank for, Oliver. It is just as it is. I would say "to feed a missunderstanding" instead. Keep your peace in your heart/mind and not allow anybody to take it from you. It is the key to keep hapiness IMO. And we do not know that guy anyway and I noticed he is putting some info in his profile, so not sure if he is really troll. But definitely if that post was mentioned to you - he should apologize for that.
