Cute video, but it has nothing to do with string theory
Leaving the 26 dimension theory aside
The 10 dimensional theory is different.
Dimensions are between energy and matter or frequency and time or electric and magnetic.
And even this is theoretical.
The video takes into account that the 4th dimension until the 10th dimension is time. Who said?
Our very own 3 dimensions could be divided into two, an electric dimension and a magnetic dimension and all things exist and variate within both.
Or the 4th dimension could be wormholes between universes within space and not time.
These are all theoretical ideas. No proof exists of other dimensions, and time is only considered a dimension for calculation purposes.
Holiday, keep thinking, it's good. what you are refering to is a point particle. Even in the video it showed a 0 dimensional point. The point particle exists in all of the dimensions but is itself a 0 dimensional object. Just as we are 3 dimensional but exist in the 10th dimension.
