A nice review on the spacetime wonderland built by string theory.

In my humble opinion, it is doubtful whether spacetime believers are really physics-minded or not.
After Minkowski postulated time as the 4th dimension and developed the spacetime worldview rather than the space-and-time physical view, modern physics became subordinated and surrendered itself to modern mathematics.

It is really ironic that when some physics-minded people want to protect physics with the space-and-time foundation, those mainstreamers in education institutes accuse them as "challenging the foundation of physics". Actually, those noble post-newtonian theorists are protecting the foundation of physics from suborination to biased applications of theoretical mathematics to build unrealistic wonderlands that can only be interpreted with modern mathematics.

I think I started laughing when the author insisted you couldn't differentiate by anything other than time.

Sure, string theory could be the modern equivalent of alchemy - a dangerous combination of wishful thinking and groupthink - but it isn't because some dimensions may be of time, not space.

The walking and moving sidewalk analogy doesn't make sense either.
