Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), ...

Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum ...

I am typing this from the Atlanta area right now, and it’s cold. In fact, the current temperature at my house is 9 degrees F and the winds are roughly 24 mph. That means it feels like -5 degrees F ...

A set of four mirrors used by the Laser Interferometer Gravitational-Wave Observatory (LIGO) to detect ripples in space-time have been cooled down so much that they are nearly at their minimum-energy ...

The absolute lowest temperature possible is -273.15 degrees Celsius. It is never possible to cool any object exactly to this temperature – one can only approach absolute zero. This is the third law of ...
