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, ...

As far as we can tell from modern science, there's no upper limit to temperature. There sure is a lower limit, though. We call that absolute zero, measured as -273.15 °C (-459.67 °F). Scientists have ...

Physicists in Germany have produced the coldest temperature ever recorded – a chilly 38 trillionths of a degree above absolute zero. The strange experiment involved dropping a quantum gas, and ...

The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves. These waves are caused by colliding ...
