Did you read your own link?

the researchers’ view suggests that it’s more correct to imagine spacetime as four dimensions of space.

Really?
“The idea of time being the fourth dimension of space did not bring much progress in physics and is in contradiction with the formalism of special relativity,” he said. “We are now developing a formalism of 3D quantum space based on Planck work. It seems that the universe is 3D from the macro to the micro level to the Planck volume, which per formalism is 3D. In this 3D space there is no ‘length contraction,’ there is no ‘time dilation.’ What really exists is that the velocity of material change is ‘relative’ in the Einstein sense.”

The article is saying that rather than 3 dimensions of space plus one dimension of time, that there are 4 dimensions of spacetime. They are positing time as not a separate physical thing but how we measure change. Exactly what I said to you some pages back.
Quote:
“Minkowski space is not 3D + T, it is 4D,” the scientists write in their most recent paper. “The point of view which considers time to be a physical entity in which material changes occur is here replaced with a more convenient view of time being merely the numerical order of material change.

To clarify - these people do not agree with you that time is absolute and that there is no such thing as relative time, PG. They merely suggest a different way of thinking about it. |
A different way of thinking about it? It's so much more than that because it changes a lot of our basic assumptions. If this is true, it would mean we cannot move forward into the future or backward into the past and time machines will remain science fiction. It also means that time does not dilate, expand, or bend.
