Is having the power to travel a realistic super power?

: Is having the power to travel to different dimensions a realistic super power?
Hey guys. I’m writing a book about teenagers with super powers. I want it to be more realistic than fantasy. But have the fantasy part be having super powers. Is being able to travel to other dimensions and seeing and interacting with ones alternate self a realistic power? Not only being able to go there yourself, but take others with you so they can meet there alternate self. Or at least one of there alternate self’s. And being able to have them travel back and forth with you for a short period of time so there isn’t some time space continium problem. Thanks.

In my opinion, not really. Since no one knows what another dimension is like, it would be hard to kind of connect with that experience.

But really, it’s your book, I say do what you want and try not to let others influence your own creative work

The very concept of a super power is completely unrealistic. Try looking at a different paradigm, where perhaps a medical condition that’s undiagnosed such as nerve damage results in the character believing they have a super power like resistance to pain or super strength. The character struggling under that misconception would make a far more interesting story.

I wouldn’t say that it is.

For one thing, nobody’s sure that “other dimensions” actually exist. Even if they do, getting there would be extremely difficult, and it’s definitely not realistic to believe that biological organisms could do it. The only thing that actually goes on inside people is chemical reactions, which simply can’t do a great deal. Travelling between universes would involve complex high energy physics, which doesn’t go on inside living people.

Once you specify any super power, you’ve crossed into the world of fantasy. There is nothing real about super powers; in fact, one could argue the reason we call them super powers is because they are totally out of the ordinary realm of reality.

Dimensions are just arguments in a point function like p(x1, x2, … xn-1, xn) where this is an n-dimensional point function. You don’t travel between dimensions, you travel along them.

For example, to climb something, you can travel along the z dimension while staying put along the x and y dimensions, but you’re not traveling between any of them. You travel from a point p1(x1,y1,z1,t1) to point p2(x2,y2,z2,t2) where each point is located within the indicated 4-dimensional space-time. So you travel between points, but along the dimensions which are just degrees of freedom to move about.

There may be alternate universes (and not all require higher dimensions). But they are more likely to be totally unlike our own than like it. That results because there are 100’s of so-called natural constants whose values uniquely define the laws of physics in this universe. But as there might be 10^500 other possibilities due to different values of those natural constants, it is clear that finding another universe with exactly the same values as our natural constants is highly unlikely. [See source.]

If you want to write a sci-fi that is heavy on the sci, I’d avoid time travel and inter dimensional multi universe travel. There is absolutely no physics basis for either one… and more and more readers recognize that fact.

You can bond with yourself only via writing that is Imagination one.
