Welcome to the Science Mondays segment! Each week here on Geek Alabama, Science Mondays will feature stuff from the world of science and science related content. Our goal here at Geek Alabama is to hopefully have you learn something useful and fulfilling. Science is a geek’s best friend, and we love featuring science content here at Geek Alabama.
Where is the coldest place in the universe? Not the dark between galaxies. The coldest spots we know of are in our own labs: wisps of atoms floating in vacuum chambers, slowed to within 38 trillionths of a degree of absolute zero, −273.15 °C. But we will never get all the way there, not with better machines, more money or more time. Here’s why: what temperature really is, how we make cold (ice, fridges, lasers, magnetic traps), and why the universe has a floor nothing can ever stand on.
