Liz,
You keep repeating your UNSUBSTANTIATED claim that both Newton and
Einstein believed in block time.
It isn't a question of belief. Newtonian and Einsteinian machanics
both imply the existence of a block universe.
I've repeatedly asked you to substantiate this claim with some
actual quotes from them but you have been unable to do so.
Please provide quotes substantiating this or withdraw the claim.
That's only fair...
Obviously Newton didn't use that phrase. Equally obviously it's
implied by his equations, as Laplace realised.
Yes, I was thinking of Laplace. Why did I wrote Pascal?

We may regard the present state of the universe as the effect of its
past and the cause of its future. An intellect which at a certain
moment would know all forces that set nature in motion, and all
positions of all items of which nature is composed, if this
intellect were also vast enough to submit these data to analysis, it
would embrace in a single formula the movements of the greatest
bodies of the universe and those of the tiniest atom; for such an
intellect nothing would be uncertain and the future just like the
past would be present before its eyes.
--Pierre Simon Laplace, A Philosophical Essay on Probabilities[3]
Einstein's equations shows that space-time is a 4D manifold, as
Minkowski pointed out. His "canonical" quote on this is:
The views of space and time which I wish to lay before you have
sprung from the soil of experimental physics, and therein lies their
strength. They are radical. Henceforth space by itself, and time by
itself, are doomed to fade away into mere shadows, and only a kind
of union of the two will preserve an independent reality.
-- Hermann Minkowski
Otherwise, just read papers on the subject of SR. It isn't a secret
that SR treats space-time as a 4D manifold.
Here is an introduction to the subject:
