Lowering the temperature is equivalent to lasering off the back two rows of seats.
***I don’t see it that way. Lowering the temperature and taking energy away from the system is like taking sugar away from the kids & giving them Ritalin so they’ll settle down. A BEC is like getting 9 kids in 9 seats, whereas you’ve been talking about getting 3 kids into 9 seats because none of them still want to touch each other.

You're missing the point [and you're also wrong.] Bose condensation at low temperature happens because bosons can ALL occupy the ground state. Fermions cannot do that. It is impossible under any circumstances to get 9 fermions into three states. It is easily possible at low temperature to get 9 bosons (or Avogadro's Number of bosons) into ONE state.

What they are doing in this experiment is creating a metastable configuration in which they create a single ground state, even though the system is not at low temperature. The bosons will then condense into that state. There is no "forcing" required; because there is only one state created by the experiment's design, the bosons condense into that state. There is no other place for them to go.

If they were fermions, this experiment would fail.

If your kids are fermions, you can yell "I'm going to turn this car around!" all day, and they still will not get into one row of seats. They can't. They're not capable of it.
