Where things take their places

In 1995, University of Colorado Boulder physicists observed BEC, a fifth state of matter that only exists within a sliver of absolute zero. At such a low temperature, individual atoms overlap so much that they collapse into a single quantum state where they collectively act as a single entity.

Positing that ‘space is where things happen’ is nothing short of stating the obvious.
It does have some merit, though.
It leads to the real subject of today’s post.

When no temperature is present – 0 degrees Kelvin – there’s no interaction between the things which happen to be there.

So whose temperature are we measuring?

The temperature of the space? Of the place harboring whatever happens there? Or not…
The temperature of the things happening to be there?
Or the amount of interaction between the things populating that place?
