ELI5:The coldest place in the Universe is the Boomerang Nebula which has a temperature of 1 K or −272.15 °C; does that mean that everything in that nebula is either liquid or solid since the boiling point of Helium is -268.9°C?

there would be so little matter that everything would still be gaseous – one of the reasons everything is so cold is because it's so un-dense (light? spacey? idk).

-268.9˚C is the boiling point **at standard pressure**. This means that something more pressured (like a steam cooker) would have higher boiling and melting points (in fact, helium doesn't even freeze at all under standard pressure), and something less pressured (like, um, space) will have lower boiling and melting points. This is because if there is pressure, there is something holding the atoms down, and it takes less energy for the molecules to fight through the "crowd" of atoms.

Oh, and fun side note, this is why many recipes call for different amounts of water and stuff when you live on mountains.
