Science measures temperatures by the presence of heat, or the absence of it.

Does this mean that cold does not exist?




You probably meant 'can we measure cold?', because if there's no heat, then basically there's cold whatever the amount of it, so it does exist. Think about the things that are so extremely cold that touching them will make your hands burn, I doubt we could measure heat on that particular substance or object, yet why does it burn?

@ICEman; The tree you are talking about was what I meant with 'out of sight' so to speak, so if I got lucky and catched it with my head, then that last split second I knew the tree existed anyway. Okey, I'd admit, I'd probably wouldn't be so happy about finding that out .
