have you ever wonder "what makes a second...a second?", wayyyy off topic Options

[lubu]

I was driving home one day in my belove celica....a question popped up in my head "what makes a second, a second"??...i know there are atomic clocks that miss a second in like 1 million year but how did we even measure a second in the first place...?

Now, a day consists of 24 hours and 1hr=3600 seconds. But we could have had 12 hours in a day and keep the same duration of a second so the number of seconds would still be 3600..it just takes twice as long to move a second to a second...so how and what instument were used to measure a second??

Imagine a second's duration were 10 times faster than today than one would says "yez..my celica can do 0-60mph in abt 60 seconds.." LOL ...yep thats a minute.

I would suggest sticking to a nominal unit of time or vector as a definition..as velocity increases the duration of the second increases, or the faster you go the slower time goes

heres the wiki

physics rocks

that's deep water, that's basically the 3rd postulate of the relativity theory that Einstein always talked about

being honest it took me a couple hours to actually get the concept of such theory and then it took me a couple days to accept it.

modern physics can get you looking like Einstein in no time.
