The coldest it can get at which most known physical activity ceases. 0°K on the Kelvin scale and as −273.15°C on the Celsius scale, and −459.67°F on the Fahrenheit scale. At temperatures very close to absolute zero, matter exhibits quantum effects such as superconductivity and superfluidity. The esoteric significance is that here energy still exists in matter sometimes called “Dark Matter,” and where Intentional Consciousness is still dynamic.
