| 1314854 | 2012-11-28 07:28:00 | Thanks Terry. Obviously the lunar effect can't cause tides of this magnitude by itself. Reminds me of the time I was told a solar eclipse was caused by the moon getting between the Earth and the sun, and a lunar eclipse was the other way round, the sun getting between Earth and the moon.

| 1314855 | 2012-11-28 07:49:00 | Fred I can't see any of your dreams happening. We are living in a hard global world. Let's get on with it. They certainly will. In about 200 years if we are stupid, sooner if we are smarter about recognising that fossil fuel is a dead end technology. The current state of (relative) peace and prosperity is a result of the sacrifice and vision of previous generations striving for a better world. The ruling mindset at present seems to be to continue propping up our unsustainable standard of living at the expense of our children (but who gives a crap, I'll be dead by then - right?). |

| 1314856 | 2012-11-28 08:21:00 | You have yet again conveniently ignored the reason for the 16 metre tides is the effect of resonance. The moon does not pull the water up 16 metres as you kept saying in the Ken Ring/moon thread :) I'll quote from that site you gave where it explains why the tides are so high: "The primary cause of the immense tides of Fundy is a resonance of the Bay of Fundy-Gulf of Maine system. The system is effectively bounded at its outer end by the edge of the continental shelf with its approximately 40:1 increase in depth. The system has a natural period of approximately 13 hours, which is close to the 12h 25m period of the dominant lunar tide of the Atlantic Ocean." I quote also from the same article: As 14 billion tons (14 cubic kilometres) of sea water flow into Minas Basin twice daily, the Nova Scotia countryside actually tilts slightly under the immense load! At mid-tide, the flow in Minas Channel north of Blomidon equals the combined flow of all the rivers and streams on Earth! And This: Tides were known to the ancients, but an understanding of their origin came only three centuries ago with the publication of Isaac Newton's Principia. Tides originate in the fact that the force of gravity decreases with distance from a massive body. The Moon exerts a force on the Earth, and Earth responds by accelerating toward the Moon; however, the waters on the side facing then Moon, being closer to the Moon, accelerate more and fall ahead of Earth. Similarly, Earth itself accelerates more than the waters on the far side and falls ahead of these waters. Thus two aqueous bulges are produced, one on the side of Earth facing the Moon, and one on the side facing away from the Moon. The rise and fall of the oceans results from Earth rotating on its axis beneath these two bulges. Looks to me like the Moon has a fair bit to do with it and a lot more likely to move mass than a 300mm hole. :lol: |

(repeat ad nauseam until it sinks in) Edit: Tacoma Bridge collapse......not due directly to wind force.....due to resonance......same as Fundy www.youtube.com Ok let’s keep it simple. We have the Moon and Resonance. Take the Resonance out of the equation and the Tide still goes up and Down. Now take the Moon out of the equation. What happens then? So you see the Tide is dependant on the Moon not Resonance. |

| 1314859 | 2012-11-28 09:23:00 | How about the Moon and Sixpence ? I can see you never studied science, maths, or logic at school :) Response to tidal force depends on shoreline and ocean bottom If the earth was entirely covered by a deep ocean, the response to tidal force would be two tidal waves a few inches high that swept around the globe once each 25 hours. On the real earth these tidal waves sweep up against and away from the shorelines. The actual daily changes in sea level at shores around the world range from one to fifty feet, depending on the shape of shoreline and ocean bottom in the vicinity of that location. Large tidal ranges are seen in areas where the ocean is confined, e.g. bays and the mouths of rivers. If the natural frequency at which water oscillates in the confined space is close to the tidal frequency (one cycle in 12.4 hours), or to a multiple of that frequency (two or more complete cycles in 12.4 hours), the water in the space will resonate with the tidal force and create large tides. The resonance of a system with a periodic force is illustrated by pushing a person in a swing. The best timing is to push at the same frequency as the swing moves when it is not pushed: its natural or resonate frequency. However, if you push at every second, or third, or forth swing, energy still builds up and the swing goes higher. If you push every 1.5 times the natural frequency, the swing will just jerk back and forth. www.scienceisart.com |

| 1314860 | 2012-11-28 09:47:00 | Did you see the American family on TV that can set fire to the "water" that comes out of their tap? And just happened to have a Television Camera etc there at the time Yea Right !! |

| 1314863 | 2012-11-28 19:47:00 | I can see you never studied science, maths, or logic at school :) That’s strange, I was thinking the same about you but I put it down to the Full Moon being on the rise and you experiencing the Resonance. :) Clearly you are into “Red Herrings”, so it surprises me you haven’t introduced wind against tide or something else. Anyway, the thread was about Fracking before you hijacked it to further your obsession with Ken Ring. So, where were we, ah yes, I doubt that a 300mm hole would move a Tectonic Plate and thereby cause an earthquake. Therefore, I see that objection as being rather Alarmist. :) |
