PeteMorris Posted October 3, 2012 Author Share Posted October 3, 2012 It might be, but over time it does add up of course, proving that the Moon and tides are extracting energy from the Earth's angular momentum. If you go bakc and look at corals from the seas back in the Devonian you see that they have growth bands for each day of growth and a year band over the course of the seasons, and they have something like 400 days in a year. The length of the year hasn't changed but the length of the day certainly has. Yes but we are talking of probably billions of years! Link to comment Share on other sites More sharing options...
truman Posted October 3, 2012 Share Posted October 3, 2012 Yes but we are talking of probably billions of years! Devonian was about 3-4oo million years ago.. Link to comment Share on other sites More sharing options...
Alcoblog Posted October 3, 2012 Share Posted October 3, 2012 Yes but we are talking of probably billions of years! To be honest Pete, billions of years is a long time (for us), but a mere scratch on perpetuity. How do you measure 'forever' anyway? If time starts at when the universe began, surely it must end when it finishes? Is this forever? This is all stuff that we don't know about, or get our heads round as it transcends our known perceived laws of science. Who's to say that perpetual motion doesn't exist ... could it exist sub-atomically in processes we're only just discovering? Although we think we know a lot, we don't actually know what's at the bottom of our own oceans! Link to comment Share on other sites More sharing options...
Obelix Posted October 3, 2012 Share Posted October 3, 2012 Yes but we are talking of probably billions of years! 400 million or so. Not that long, when you consider the timespan of the Universe. incidentally if we ever seriously used tidal power, that's where would be tapping the energy from - the more tidal power we use the more the Earth slows down. Not truly renewable and one to use to wind up the greenies if you feel that way inclined :-) Link to comment Share on other sites More sharing options...

I don't know if it's a 'truism' or not, but if we made a huge list of things we 'do' know about, we could probably make a longer list of stuff we don't know about!..AND..That wouldn't include stuff we don't know about! At least that's what I think I mean! Link to comment Share on other sites More sharing options...
PeteMorris Posted October 3, 2012 Author Share Posted October 3, 2012 Devonian was about 3-4oo million years ago.. I thought Devonian was about 300 miles South down the M5? Link to comment Share on other sites More sharing options...
