Questions<br />

percentage of air shifted be much greater than the percentage<br />

of water shifted?<br />

A: Yes, because gravity wouldn’t act as much on the air to stop it<br />

moving from the far side. <strong>The</strong> airtide is about 20% at times but a<br />

watertide can rise about two metres which probably isn’t as much<br />

as 20%<br />

Q: How did you calculate one moon cycle? <strong>The</strong> dates you<br />

gave aren’t 18.6 years apart.<br />

A: Anything from 18-20. It varies. You look for the same<br />

conditions combining together within 6 months or so.<br />

Q: Can you tell where north and south is from looking at the<br />

<strong>Moon</strong>?<br />

A: <strong>The</strong> <strong>Moon</strong> generally rises in the east and sets west or<br />

northwest. When Full, the <strong>Moon</strong> is opposite to the Sun in the sky,<br />

and to observers in the Northern Hemisphere of the Earth it lies<br />

due south at the stroke of midnight. For those watching from the<br />

Southern Hemisphere, it lies due north at midnight.<br />

Q: It seems to me it would be important to know the shape of<br />

the bulging atmosphere, and specifically how the height of the<br />

atmosphere on the far side from the moon compares to that of<br />

the portions at right angles to the moon ie the “low tide”<br />

zones. Is there any way of judging simply whether the<br />

atmosphere on the far side is thicker or thinner than that at<br />

the sides of Earth -what you’d call the midzone atmosphere?<br />

A: I don’t think there would be any midzone atmosphere.<br />

Presumably the atmosphere on the far side is lower than that at<br />

the sides of the Earth because the <strong>Moon</strong> would be pulling the<br />

atmosphere in this zone. That would to some extent take in the<br />
