In the Principia Newton defined time and space for physics:
I. Absolute, true, and mathematical time, of itself, and from its own
nature, flows equably without relation to anything external, and by
another name is called duration:
relative, apparent, and common time, is some sensible and external
(whether accurate or unequable) measure of duration by the means of
motion, which is commonly used instead of true time; such as an hour,
a day, a month, a year.
II. Absolute space, in its own nature, without relation to anything
external, remains always similar and immovable.
Relative space is some movable dimension or measure of the absolute
spaces; which our senses determine by its position to bodies; and
which is commonly taken for immovable space; such is the dimension of
a subterraneous, an aerial, or celestial space, determined by its
position in respect of the earth.
We all know that Einstein had something to say on this topic.
He writes in Relativity Chapter 9:

Newton is somehow wrong. GR gives the correct picture of dynamic spacetime.
My idea is to treat space as observation of spacetime and lenght as
observable. It is in fact the case, that lenght is observable and spacetime ...

time 'paces'. Its a bit metaphoric, this picture. Maybe I find some other
words for that.
Its a picture of something imaginary, so its somehow wrong. Space is
assumned as orthogonal to time and hence 'move' with the time axis. Time is
assumned to 'pace' with c. So ds^2=c^2dt^2- dx^2-dy^2-dz^2, what is
four-dimensional and complex and c is the factor to convert time into length
or vice versa.

Newton was wrong. Electromagnetism wasn't adequately modeled until
the 1860s. There wasn't any EM in 1687.

Einstein - not being stupid - went with Maxwell. 140 years of
observation and thought can go places. Toss meat to your
mathematicians and they'll toss back tools.
