1. General Term: Spacetime
Spacetime A continuum of four dimensions (3 spatial and 1 temporal) in which any object
or event can be located.
2. Physics Topic: General Relativity
In it, matter and spacetime are interrelated physical phenomena.
Matter moves along curved paths due to the curvature of spacetime.
At the same time, spacetime is curved because of the presence
and distribution of matter. Hence the

called "spacetime ". In three dimensions, we measure
the distance r between points by the usual Pythagorean measure:
x 2 + y 2 + z 2 = r 2 .
In spacetime, we measure the "interval" or

turn, would alter the curvature of spacetime, thus giving the field equations

Although God transcends spacetime
as its cause, God is nevertheless temporal, since . . . by creating spacetime,
God creates new temporal relations in the Divine being itself. Allowing God to have temporal relations

8. General Term: Block Universe
Block Universe A view of spacetime that affords equal (ontological ) status to all points in
spacetime, thus regarding temporality as an illusory human construct with no
reference to reality as understood by modern physics.

into huge portions of spacetime in which
the natural constants and even the specific laws of physics can vary. The effect
of inflation on the problem of t=0, however, is fascinating. In some
inflationary cosmologies, the Hawking -Penrose
10. General Term: Past Lightcone
A cone-shaped portion of spacetime containing all (past) locations from which
light could arrive at a particular location within spacetime (the tip of the
cone). The tip can be reached from points inside the cone at the speed of light
