I've been arguing with complete idiots "units of length and time are not fitting" HA HA AH HA HA>>>>>>>>>>>almost time to take your idiot pill. > > 'Space' and 'time' are concepts to describe experiences we have in everyday life. Spacetime is not an everyday experience. But we can try to estimate, how that might look like. Only problem: we cannot see spacetime, only assume something similar would exist. And we are limited to a certain observation point (vicinity of planet Earth) and cannot move around the universe like 'Starship Enterprise'. To illustrate the problem, lets use an example: imagine, that everything we could see from the world is the picture in a microscope. You can observe everything, but magnified by - say - a factor of 100. Now you come to a large build (say the Eiffel Tower) and want to find out, how that might look like. You peep through the microscope and wander, what the **** you are observing. We could guess and try to compare our guesses with what we can see. If the picture somehow match our ideas, we are happy, otherwise not. So we need to make assumptions about how our very tiny fragment of the real world would extend into the larger realms. There we must not extend our own concepts into the large scale, but need to find something possible in the large scale, which would look like our observations on the small scale. IOW: space and time (as we know them) are a subset of something larger, which has other main features (that we do not know, but want to find out). TH
