Scientists just broke the record for the coldest temperature ever measured in a lab: They achieved the bone-chilling temperature of 38 trillionths of a degree above -273.15 Celsius by dropping ...

How would you go about determining absolute zero? Intuitively, it seems like you’d need some complicated physics setup with lasers and maybe some liquid helium. But as it turns out, all you need is ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Under a tangled mess of pipes, tubes, gauges, ...

Absolute zero is the lowest theoretical temperature, which scientists have defined as minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius). That's even colder than outer space. So far, ...

Artists Felicia LeRoy and Carolyn Spears work with molten glass, some of the hottest material on earth, yet their recent exhibit “Absolute Zero” connotes the coldest temperature possible. “Absolute ...
