Thought of the day
Someone explained to me yesterday, that the moon, the sun and the earth are the perfect size.If they were any different in size and distance from each other, we wouldn't have total solar or lunar eclipses. That is food for thought!
Have you got a thought of the day?
...and those who were seen dancing were thought to be insane by those who could not hear the music.FN
Hi Granny yes it is amazing and it all goes much, much further. The moon is the perfect size and distance from the earth to exert gravitational pull that controls the tides. The earth is the perfect distance from the sun to support water and therefore life. Nearer the sun it would be too hot, further away it would be too cold. For an incredible insight into these things and much, much more watch Brian Cox's amazing series Wonders of the Universe, currently on Sky's Eden channel.
Yes it is perfectly feasible and mathematically it is virtually a certainty. Our sun is a star with its own solar system, including the earth and other planets orbiting around it. The latest estimate of the number of stars in the observable universe is approximately 5 times the number of grains of sand on planet earth. These numbers are inconceivable. Have a look at :

You are right that a light year is the distance that light travels in one year. But it only takes 8 minutes for the light from the Sun to reach us. A light year is 186,000 ( the speed of light in 1 second) x 60 x 60 x 24 x 365= 5,865,696,000,000 miles!
