In GR theory ,Does the idea of the product of space and time really abstract?

Question

Do we feel space time ?

Answer 1

The product of space and time is not so much an abstraction as much as an aberrated perception. ( Why, In GR theory, is everyone always going deductively DOWNWARDS into the collapse rather than inductively tracking the event back to original precipitating events? The answers are THERE.)

Answer 2

In General Relativity we do not use the concept of Space and Time rather it is SpaceTime.
Time and space are dimensions (aspects) of the same thing spacetime.

A body is stationary with respect to itself so it is travelling purely along the time axis of spacetime.(4 dimensions which are 1 time axis and 3 space axes)
When we look at another body moving with respect to us, some of its movement along the time axis is converted into movement along the space axis.
In 4-vectors this is easily seen as just a rotation in the 4-space

Here are two examples of how we feel aspects of spacetime. There are others:

1 Mass curves space-time. We are travelling through spacetime, even though we are stationary with respect to ourselves. We are then just travelling through the time part (of the 4 dimensions). We feel our bodies being deflected by the solid earth, from our curved path through spacetime. This is what we think of as our weight. We can feel our weight, as we must support our body as it is deflected from the shortest path through spacetime by the earth's surface.

2 A magnetic field, generated by moving electrical fields can be detected by us when we push two north poles of magnets together. The electric and the magnetic fields are manifestations of each other in time-space.
