You cannot make a wish on a falling star!?
A certain astronomer measured the visible period of falling stars and found that the period is only 0.2∼0.6. No matter how you look at it, it is impossible to make a wish on the falling star three times within this short period, isn’t it? What do you think?
The day when the moon is leaving the earth.
Recent research found that the only satellite of the earth, the moon, is leaving the earth about 3cm a year.
The cause is the “coming and going of the tide” caused by the gravity which affects between the moon and the earth. The flux and reflux of the tides moves the sea and air of the earth and the earth itself twists a little. This twist makes the moon to go away from the earth and the velocity rotation is slow. Conversely, in the dawn of time, the moon was nearer and looked bigger than now.
