While sitting in my chair and pondering things, actually, that makes it seem like I was calmly doing this… when in fact I was very annoyed at my routine being changed by daylights savings and was making very loud statements such as:
“How dare they mess with time!”
“Do they not know how important routines and clocks are to most people?”
“It throws off the entire day! I used to wake up in the light/dark(depending on which way the clock goes and went to bed in the opposite and now they have disrupted that pattern and flipped it!”
Ok, my temper tantrum died down, but I felt discombobulated and very out of touch. I’m still adjusting. I know it sounds like I’m being a drama queen, but I have a routine and when it gets messed with, my head gets very tired and sore.
Anyway, back to pondering. As we know the earth’s rotation changes by around 1 meter every four years. This is apparently too slow to notice the time dilation, but that does not mean it is not happening! Just because it’s slow, doesn’t mean it doesn’t exist!
It does not apparently have much impact on gravatational time dilation, but does not mean it is not something that is happening! They just say it is so slow that it has no ‘measurable’ impact on time dilation.
Sounds like a challenge?
Ok first off when does time dilation actually become measurable? Answer is approximately 0.1c (“c” is light speed) and the speed of light is 299,792,458 meters per second then we calculate a year into seconds, which equals 31,536,000 seconds.
Now we calculate the velocity, which means we have the displacement and the speed, so the velocity equals displacement over time v=299,792,458/0.1c so the velocity = 9.5063564814815 m/s
Next needed is the acceleration of Earth over 4 years being acceleration = (final velocity − initial velocity) / Acceleration time
(38.025425925926 – 9.5063564814815)/31536000 = 0.0000009043
Ok we’re starting to see why it is immesurable or an unnoticable ability for time dialation right? I think just the starting blocks mean we can say it will take millions, nope, billions of years before the slow down of the rotation is noticed? I’m really sorry, I got really bored doing the math and explaining it… Btw I was doing it on a calculator and got annoyed as I had to go searching for one that allowed me to ‘raise to the power of’ and finally gave up and just did it the slow way, pfft.
Anyway to continue…
Please don’t get confused by the word ‘Acceleration’, that is just the mathmatic term for the calculation, but in fact the Earth’s rotation is slowing, not increasing. The length of the days are actually getting longer by 0.018 miliseconds per year. So, it’s around 55,556 years that the time will be changed by 1 second. 3,333,333 years that the time is changed by 1 minute. 200,001,600 years that it is changed by an hour.
So I have explained all of that, mostly to say –
How do those annoying bastards think that they have the right to change my clock by 60 minutes every 6 months!!!!
