Day 259 Time

Such an interesting concept: time.  Try to come up with a good definition. Sure, you'll use terms like before, now and after. Even the great physicists have struggled with this. And what do you make of this Theory of Relativity that talks about time being different depending on how fast you are going and only really noticeable at speeds approaching the speed of light? OK, that's just weird you say. But what's even weirder is that it's been proven experimentally. Sure the math is all there, but experiments have proven it out.  I think one of the hardest things in life is to take a hard look at your beliefs and be willing to see if they check out experimentally. And if your beliefs don't prove out can you change?  Some people like to ignore reality and continue on. But what is reality you say?  Ahh, the great eternal question. And just to be clear, just because some muckity muck with more degrees than a thermometer says it doesn't make it true. History is replete with this lesson. We have to trust to a certain degree. Did the designer of the elevator you just got in use the correct values to determine the correct size of cable so it doesn't break? Are the safety systems designed correctly and functional? I've always trusted this. Do you?
