"Rethinking Einstein: The end of space-time. It was a speech that changed the way we think of space and time. The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea - what we now know as special relativity ….
--Note that Minkowski was supposed to be trying to make sense of Einstein’s special relativity (SR) in 1908; that means it didn’t make sense as recognized in 1908!
“…- describing how things shrink as they move faster and time becomes distorted.”
--That is such things as the twin paradox, which many still point out does not make sense, such as Herbert Dingle (Herbert Dingle: Science at the Crossroads 1972)
“ "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and only a union of the two will preserve an independent reality." And so space-time - the malleable fabric whose geometry can be changed by the gravity of stars, planets and matter - was born. “
--It was one of the bodges done in relativity, next the article is going to suggest that was wrong:
“It is a concept that has served us well, but if physicist Petr Horava is right, it may be no more than a mirage. Horava, who is at the University of California, Berkeley, wants to rip this fabric apart…”
--Rip it apart because its nonsense.
“…and set time and space free from one another in order to come up with a unified theory that reconciles the disparate worlds of quantum mechanics and gravity - one the most pressing challenges to modern physics."”
--i.e. get rid of the bodges from relativity and we are back to physics that makes sense.

Einstein was good, but that was 100 years ago. Too much expectation from just one man.
The fallacy is to think that when you perceive a traveller through a space-time projection, then that affects the traveller. So if different observers perceive the traveller, the traveller becomes confused about his state with respect to his length and time. Of cource the perception affects the observer, but not the traveller.
