So time is the first dimension with a relative value of zero?
Space having the values of 1,2,3 and time the value of 0, as space forms a geometrical progression?
So what i am asking is 'if dimension limited to spatical dimensions then time is not a dimension but an element of the continium? So are light, heat, pressure, etc. but if time is a dimension then are not the others as well?
Just the thought of scientist of today?

Including cause-and-effect in equations produces 4-dimensional space-time.
Is causality an inherent and necessary characteristic of the Universe, or just an illusion produced by the way our brains interpret the world?
It's real, say physicists, who believe they have worked out how the Universe is constructed from the tiniest building-blocks of space-time.
The finding could also help the development of a theory of quantum gravity, which would marry the two currently estranged physical theories of the Universe: quantum theory and relativity.
Quantum theory describes the Universe at the tiniest possible scale - about 10-35 metres (about 1020 times smaller than the radius of a proton). It predicts that on this scale the apparently smooth fabric of space and time must degenerate into a kind of 'foam' in which connections between different points are constantly appearing and vanishing.

Tiling together tiny triangles of space-time gave rise to a universe that looks just like our own.
Renate Loll of Utrecht University in the Netherlands and her co-workers have now found a way to assemble the pieces so that they inevitably produce a four-dimensional Universe. Instead of assuming that all tilings are allowed, they impose two constraints.
First, the theory of relativity must apply within each individual tile (so that nothing can travel through it faster than light) and second, the assembly must preserve causality. This means that a piece of space-time cannot be constructed in such a way that an 'event' - some change in the Universe - precedes its cause.
When they enforced these criteria on their calculations, the researchers ended up with universes with three spatial dimensions and one time dimension - just like our own1.
It was "like magic", says Loll.
Even more startling, they found that typical universes generated this way started off small and got bigger - they expanded, just like the real Universe has done since the big bang. This was completely unexpected - there was nothing in the tiling rules that seemed to demand it. "We're completely stunned," says Loll.
She admits that there's no a priori reason to demand that quantum space-time has to observe causality: the researchers put it into their equations by hand. But that, it seems, is the only way to end up with a realistic Universe.
