Is Time Real?Kant was among the first to postulate an unbending time dimension akin to spatial ones. Einstein showed time dilation in Special Relativity by discussing "signals" of light being used to "measure time". Fair enough, but doesn't this presume the motion of light?
Suppose there was just a single atom in its ground state in a Universe so no light would be emitted [and of course it couldn't be prey to radioactive decay - gold would qualify] and obviously none could be absorbed since we're assuming a Universe with JUST one atom [it COULD happen]. HOW would an observer know how mush time had passed? OK, an observer could create motion by observing, so let's have NO observer...would time exist or not?
This is a little like asking if the falling tree in the forest makes a sound if nobody is there to hear it, but a tape recorder wrecks THAT. This postulated Universe has no observer.
