What is twice as cold as zero degrees?
That depends on what temperature scale you are using. Zero degrees Celsius is not as cold as it can get. "Absolute zero," or zero kelvins, is the coldest temperature possible.
So, if you are measuring in kelvins, twice as cold is not possible. However, if you are using the Celsius scale, zero degrees is actually 273.15 degrees above absolute zero. So, twice as cold would be -136.575 degrees Celsius.
