Axial rotation describes a point on the edge of a plane that moves at right angles to its centre in a way that will cause it to first approach, then recede from any given direction. In other words, if you place a marker on a wheel standing on the ground, that marker will first travel […]Read More “The moon rotates on its axis” Oh, no it doesn’t!
DATA: Earth’s circumference is 24887.64 miles( 40044.2 km) 24887.64 x 365.25 cycles= 90900210 miles The radius of this circle is 1447485.7miles, the distance to the sun The sun appears to be 0.5degrees The length of the circle divided by 720(360×2) will give the real diameter of the sun 90900210/ 720 =12625miles( 20313.6 km) You may […]Read More Distance to the Sun
It was not until man began to explore the universe with telescopes that he began to consider the question of the speed of light. In the early seventeenth century, the famous Italian scientist, Galileo, first attempted to measure the speed of light, unsuccessfully. But, about fifty years later, the Danish astronomer, Ole Römer, in 1676, measured the speed of light by […]Read More The Speed of Light
All astronomical measurement is only possible using predictable cycles of motion. A ‘Day’ is one turn of the Earth on its axis. A ‘Year’ is one cycle of the Earth round the Sun. There is also the moon’s cycle of 27.32 days, and Precession of the Equinoxes, which I will discuss later. Our measure of […]Read More The God Equation
Our moon is still as mysterious and magical as when our ancestors accorded it god-like powers. Second, only to the sun in its influence on Mother Earth, it causes the oceans to move, affects the growth of all life and most definitely stirs the imagination. Yet we still know very little about it. Obviously, I […]Read More Distance to the Moon
