the moon did that. DINOSAUR EXTINCTION i've always looked at the moon and wonderd if dinosaurs saw the same view. the world was a very different place, then, and i wonderd if the moon might have looked different. this started me thinking "did the moon ever spin?". so i asked nasa this question. they replied me and said "it did spin and stopped 200 million to 2 billion years ago." so then i thought "the solar system is 6 billion years old, their guess is one third of all time, maybe this isn't a much looked into question. TIDES : everybody knows the tide and the moon are linked but how? the thinking at present is that gravity, from the moon, pulls at the oceans. i think it was newton that said gravity is not acting on a body if it's already falling towards the target body. thats why astronauts are weightless in orbit. i got a tidal predictor and looked at the height of tides, at a time of full moon, on the gm line at midnight. this, according to the gravatational model, should have been high tide. it wasn't. it wasn't even close. the moon was actually above the low tide. to my mind the gravatational model was wrong but this leaves the question of "what does cause tides?" i learnt many, years ago, that the earth and moon move as a dipole. this means as well as the moon falling to earth, the earth is falling towards the moon. but because the moon moves the earth is only deviated a little bit. i have since found out it is called the bari centre. this means the earth goes on a little wander every month. this slight deviation is, what i believe, the cause of tides K TIME: the time of the dinosaurs. they where no fly by nights having arrived on earth and excisted about 160 million years. i was watching a programme on telly about giant carved stones that where moved a long way from where they were dug out. the presenter said "if you are moving that much weight you would use water ways" then i thought these massive dino's must have lived in water (not new thinking but where?). k time, i thought, could have been the calm time the earths history where there where no tides. this would have led to large flat areas at the edge of continents (no tidal erosion) and this area was inhabited by many animals. so there were animal living on land, in sea, up in the air and in shallow water. T TIME: time of the tides the moon stopped spinning or became tidally locked and animals still lived on land, sea and air, but the animals that lived in shallow water disapeard. by all reconing, as 60% of all animals extincted, the shallow water environment was a pretty happening place. willem willemse

it didn't, thanks. this talks about the high tide pointing at the moon. i disagree.

i think before tidal lock there were no tides then, sudennly, they started.

the gravitational explination would call for the bulge to be pointing at the moon, but i don't think it does. i got a tidal predictor and looked at the tide of a place on the meridian line at midnight at a time of full moon. the moon didn't point at high tide but low tide. therefore, i don't believe in the gravitational model for tides

i mean, as it is today, tidally locked. but when did it lock?

i asked when you think the moon stopped spinning. well i think it was 65 million years ago.

i got a tidal predictor and looked at tides at a time of full moon (on the gm line). it wasn't actually high but it was low. therefore i think not high, but low tides point at the moon.

it doesn't spin, it rotates. that means it turns it's back on the sun every month (rotate) but it doesn't spin. but when did it stop?

i asked nasa "did the moon ever spin, if so, when did it stop?". they said "it did spin and stopped 200 million to 2 billion years ago." i don't think so. what do you think?
