I was wandering whether time really "exists" or is it just a mathematical parameter used to describe how things change.

    $\begingroup$ You have to define exist before you can ask this question. And you should think about why you put the word "just" in there; what is it about thew phrase that follows that requires you to deprecate it? $\endgroup$ – dmckee --- ex-moderator kitten Jan 9 '16 at 19:42

    $\begingroup$ I mean, does it exist in the same way space does or is it just as a mathematical tool as velocity or length is $\endgroup$ – SaudiBombsYemen Jan 9 '16 at 19:49

    $\begingroup$ It exists in the same sense as space exists. Space can be measured with rods and time can be measured with clocks. Same difference. $\endgroup$ – CuriousOne Jan 9 '16 at 19:55

    $\begingroup$ @curiousOne But velocity or energy can also be measured, but that doesnt mean they exist, they are just quantities that arise from our description of the universe using mathematics. $\endgroup$ – SaudiBombsYemen Jan 9 '16 at 20:00
