Re: The Sun: Millions of miles away?
Pastor, they can measure the distance of the moon with a laser. The light from the laser travels at a known speed. When pointed at the moon, the light travels towards the moon, the moon then reflects part of it back towards earth, and a sensitive sensor on the ground can measure the EXACT time that was required for the light to travel to the moon and back.
Split this time in half (because you only need to know the time it took to actually reach the moon), and multiply it by the speed of laser light (299792458 metres/second). You then know the exact distance earth-moon. (distances vary because the moons orbit is an elipse.
Another question.. How, HOW could Noah taken two of each animal of the world onto his boat? Must have been one BIIIIIIIG boat!
The class of animals that human beings belong to, the mammals, includes close to 5,000 species. The number of birds is over 15,000. There are more than 3,000 kinds of snakes, and 300 kinds of turtles (Yes, TURTLES).
The mollusk family, which includes sea animals like the clam, has more than 100,000 members, while the lobster and crab family has over 20,000. There are some 15,000 species of protozoans, or one-celled animals, but the record for the number of different species is held by insects, with well over 750,000!
The best estimate is that there are at least three million different kinds of animals on earth!
Must have been cozy, a boat with 6.000.001 passengers
