If an object in the cosmos has a speed of 0, does it still exist?

If it also has a temperature of 0 Kelvin, what happens to such an object?

Answer

Dear Roland,

Why should an object that is stationary not exist? Speed ​​is a relative quantity, which depends on the observer. If you are stationary on the Earth, then the Earth has a velocity equal to zero for you. And I think we agree that Earth exists.

Regarding your question about temperature, it is impossible for an object to reach a temperature of 0K. At a very low temperature close to 0 degrees Kelvin, the object no longer has any thermal energy. All atoms and molecules are stationary, with the exception of quantum vibrations which, however, also have the smallest amplitude they can have.

Kind regards,

Philippe Tassin
