Godspeed is not actually a measurable speed at which something travels AND Lightspeed is this totally weird thing.
But (as usual)(hopefully) let’s talk about something interesting….the idea that God is Light.
In the book of 1 John 1:5 it says, “…God is light and in Him is no darkness at all.”
This was written long before any technology or explanation of science type stuff- but it is an amazing thought. John’s world did not have electricity, just fire and sunlight. Which means he also had amazing stars each night (but that’s another post..) Light itself shows God’s nature. It makes you feel good when you stand in sunshine -even if you are indoors. And the way a beam of light will shine into a room- yet you never see a beam of darkness “darking” into a room. (I made up ‘darking’)
As we attend school, we learn that light travels at 300,000,000 meters per second, or 186,000 miles per second, store it in our memory banks until a DJ on the radio asks or it’s in the trivia part of the newspaper. Galileo made an attempt to find the speed of light in 1630 but could only prove that it was ‘very fast’. (I love that) He had noticed that light was not ‘instantaneous’. That has got to be hard to notice. The things you can do when you don’t sit in front of the TV- like… think!
Sound is wicked slow by comparison, you can hear a ‘slapback’ echo in a room with no carpet even if its only 12′ wide. The speed of smell- well, it depends. But who would have guessed that light had a speed ? In 1748 James Bradley calculated the speed from the direction that light fell from a star to earth, about 176,000 miles per second. In 1849 another scientist, Fizeau, improved on Galileo’s method and came up with a new figure—196,000 miles per second. In 1927 Albert Michaelson changed the figure for the speed of light. He said it was 186,295 miles per second. In 1972 the official speed of light was said to be 186,282.3959 miles per second. (btw that’s 671 million mph) Then Albert Einstein came along and made this the speed limit that no one could break.
But it gets weirder. Light does have a speed and a speed limit, and if not a limit -then something else… The big deal with ‘c’ (symbol for speed of light)(made famous in E=mc²) I heard a guy explaining a small part of it and it has to do with how objects appear when they are coming at you. Like if I am approaching you at 50 mph and you are going 50 mph, it will look like I am going 100 mph to you. But not so with c. -and if you are watching c from a parallel viewpoint you will notice that it bends time. (picture dribbling a basketball standing still and then while walking- while you are still it goes just up and down in a straight line, but when you walk it moves in diagonal directions- but it does not change speed.) There is this whole big thing about how time moves slower for those in motion and space travel-
But- you are not in space travel and your time here on earth is going by (quicker than we think -or want it to) and while its fun to learn science… it’s much more fun when you have already made peace with God and been forgiven. (so take care of that part right now if you have not already done so) (I will wait.) ( – ) (ok, are we good?)
The speed of light does not change and Malachi 3v.6 says that God does not change. God made all kinds of stuff that show Him. Nature and Science are full of evidence of God’s hand. Malachi did not know that the speed of light does not change- he just said what God told him. 1 John 1v7 says ‘But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.’
Light exposes stuff and bad stuff is synonymous with darkness and shadows. I actually think I look good in black but I want my heart and my eyes and my life to shine brightly for Jesus. (note: it is January right now, and it is cold- but I would love to be tanned!)(but having a tan does not automatically equal salvation)(just saying)
In Heaven there is ‘no need of sun or moon, for the glory of God illuminates the city, and the Lamb is its light.’ Rev 21v23
and when God spoke everything into existence, the first thing He said was ‘Let there be light’. (pretty cool) amen.
Since 1983 the accepted value of the speed of light (c) is huge: 299792.458 km. per second in vacuum, so what is the distance should be covered by the speed of light in a day, it is an out of imagination value, no distance on the surface of earth is suitable, it necessitates to be described; an astronomical measure by the motion of a celestial objet with a known motion, hence the moon is the choice; because it is the nearest celestial object and its motion around earth is known well.
In Physics; the light and all physical forces in nature have a unified uppermost magnitude of speed, in vacuum, i.e. in a system of motion isolated from any outside effect. So, to use the E-M system as a measure in a Balanced Equation with light; it should be isolated also from any outside effect, i.e. as it was reckoned before that earth has no motion around sun, and the moon is devoid from the variation ratio in distance; that cannot be detected by the naked eye.
By using the isolated E-M system as a measure to the distance covered by the speed of light in a day; the motion should be relative to a far star, hence the moon’s mean orbital velocity should be analyzed in the original direction after a cycle; and the rotation period of the earth (a sidereal day) is considered, which is: 86164.09966 seconds. According to NASA; the moon’s average orbital velocity is about: 1.023 km./ seconds (Revised 08-01-2014)4, By calculation using the value: 1.022794272 (about 1.023) km./ seconds; the distance covered by the speed of light in a day is comparable to the distance covered by the moon in 1000 lunar years (12000 cycles), as the lunar year is considered in the lunar calendar since ancient times as 12 cycles of the moon around earth.
The average moon’s velocity is: 1.022794272 km./ seconds, the basic ratio is: 0.8915725423; so the basic moon’s velocity is: (1.022794272 × 0.8915725423) = 0.9118952893 km./ seconds. The moon’s revolution period (T’) is: 27.32166088 mean earth days = 27.32166088 × 24 × 60 × 60 = 2360591.5 seconds, hence the length of the basic moon’s orbit (L’) after one cycle = v’ × T’ = 0.9118952893 × 2360591.5 = 2152612.269 km., the lunar distance in 12000 cycles = 2583134723 km., then the speed of light in vacuum is: 2583134723/ 86164.09966 = 299792.458 km. per second, which is the exact known and accepted value in Physics for speed of light in vacuum since 1983.
Thank you Dr.Doudah, I appreciate the details- (makes this look like a real science-y high-brow type blog thingy) you are always welcome here!
