a long time ago

feeling great, though my ankle hurts a bit more after soccer and i pulled a muscle slightly.
but great.  we won.

here's something to think about:

the Earth's rotation is slowing down.  This is why we add a Leap Second as necessary.  In the last 36 years, we've added 24 leap seconds to our clocks/time.  we can't predict when exactly we'll need to add leap seconds because the Earth's rotation doesn't slow at a fixed rate, it's variable.  but if the Earth has been slowing down, then it must have been spinning faster before right?  and if the Earth has always been slowing down, how fast might it have been spinning if the Earth is billions of years old?

so let's say that maybe we add just one leap second every 3 years, which is less than it seems we do add, and then suggest that the earth is 1 billion years old.  doing some math:
1,000,000,000 / 3 = ~333,333,333.3 (number of leap seconds of change)
333,333,333.3/60 (minutes of change) /60 (hours of change) /24 (days of change) =  ~3858 days.

3858 days worth of change in time, which means change in speed of the Earth's rotation.  i don't know the math for figuring out how much faster the Earth would be spinning, but it seems like it would be quite a lot.  amirite?

so if the earth is billions of years old, it probably would have been spinning wicked fast.
i guess this is all considering that the Earth has been slowing down at about the same rate, the wikipedia page said that it's a slighty variable rate.

just something to think about.  something that you'd wonder "how did that work out if the Earth is really that old?"

"i have a theory about that"
oh lulz.
