And traveling to it is quite different. Then you have traveled only to one of many possible futures, one timeline in the multiverse. Tony and Bruce didn't recommend it as regular activity, common as it is here. This universe has clearly had its timeline splintered from what it once was. Sometimes I am curious how these events would unfold had we not come here. Yes or no is easier than to what degree.
What are shapes in the Force like - our physical bodies, a reflection of our spirit? Dr. Strange has taught many people magic, including those not from his universe or our multiverse or even from universes that have magic (or ones with different magic). His seminar's right in ESD's schedule, though I'm not certain how much it happens. Some abilities and skills can cross to a wide swathe of people. But others, like the Force, so far have not. Are they impossible or simply not yet seen? We may never know, unless the latter becomes proven. It may all be interrelated. They all have some ties to genetics, better or worse understood.
Wakanda, here, has managed a greater isolation than anything America accomplished in the early 20th century. No one who enters it here returns, and they do not welcome visitors. That is a common state in its history, usually changed by my father to some degree at some point. If my father is here and leads, he hasn't done so yet.
