1

what is the relative view of space and time

they are not separate but instead are intertwined to make up a 4D universe (3D and time)

2

what is the space time interval equation equation

Δs^2 = Δs'^2 = c^2Δt^2 - Δx^2

3

if something is invariant what does that mean

it has the same value in all inertial reference frames

4

what is the space time interval in terms of spacetime geometry

it is the distance between events in spacetime

5

what is the space time interval in 'real world' terms

time of a clock carried along two paths

6

since both Δs and c are invariant what else must be invariant and what is it's name

Δt' is invariant
known as the proper time

7

what does a clock do in relativistic terms

measures the distance you travel in spacetime
