The Cosmic Speed Limit?

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has a wavelegth in the range of about 380 nanometers to about 740 nanometers – between the invisible infrared, with longer wavelengths and the invisible ultraviolet, with shorter wavelengths. In physics, the term light sometimes refers to electromagnetic radiation, of any wavelength, whether visible or not.

Genesis 1-5 is a passage that can lead to circular reasoning. It is written, “In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.”
(Genesis 1:1-5 KJV)

I have seen many pointless arguments over this topic with the core of the question being, how could the days of Genesis 1 be literal if the Sun wasn’t created until the fourth day?

Jonathan Sarfat wrote an excellent article in Creation Ministries International. He wrote, “We know today that all it takes to have a day-night cycle is a rotating Earth and light coming from one direction. The Bible tells us clearly that God created light on the first day, as well as the Earth. Thus we can deduce that the Earth was already rotating in space relative to this created light.

God can, of course, create light without a secondary source. We are told that in the new heavens and Earth there will be no need for sun or moon. In Genesis, God even defines a day and a night in terms of light or its absence.”

And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.
(Revelation 21:23 KJV)

In addition, John Calvin write an interesting article that states that Genesis means what it says.

Light exerts physical pressure on objects in its path, a phenomenon which can be deduced by John Clerk Maxwell’s equations, but can be more easily explained by the particle nature of light: photons strike and transfer their momentum. Light pressure is equal to the power of the light beam divided by ‘c’, the speed of light. Due to the magnitude of ‘c’, the effect of light pressure is negligible for everyday objects. For example, a one-milliwatt laser pointer exerts a force of about 3.3 piconewtons on the object being illuminated; thus, one could lift a U. S. penny with laser pointers, but doing so would require about 30 billion 1-mW laser pointers. However, in nanometer-scale applications such as NEMS, the effect of light pressure is more significant, and exploiting light pressure to drive NEMS mechanisms and to flip nanometer-scale physical switches in integrated circuits is an active area of research.

At larger scales, light pressure can cause asteroids to spin faster, acting on their irregular shapes as on the vanes of a windmill. The possibility to make solar sails that would accelerate spaceships in space is also under investigation.

Although the motion of the Crookes radiometer was originally attributed to light pressure, this interpretation is incorrect; the characteristic Crookes rotation is the result of a partial vacuum. This should not be confused with the Nichols radiometer, in which the (slight) motion caused by torque (though not enough for full rotation against friction) is directly caused by light pressure.

If light has energy, it also has mass, It is my firm belief that there is no such thing as nothing. Even ‘space’ being a vacuum contains dark matter, a subject not completely understood yet. Where there is matter, there is also anti-matter.

On 2011, Victor Elias Espinoza Guedez reported his findings (unfortunately to much ridicule). He said, “According to my research, the colors of a reflector of high power do not reach the clouds, this is because the color is attracted by gravity. If the light it has waves is because it has weight. A wave is produced by touch. If each color produces a different wavelength, it is because they have a different weight.

Darkness appears to have no weight or mass as it is the complete absence of light, however a shadow would in fact have weight. A shadow is the blockage of the path that light travels in, thereby reducing the number of photons and elections being “cast” upon the object being weighed. A shadow would weigh less than a illuminated object.

The speed of light in a vacuum (C2) had been thought to be slowing down for many years, therefore light speed is absolutely useless as a way to determine the age of the universe.

For most practical purposes, light moves in a straight line. However, it does bend a little due to gravity. The small curvature of light passing near the Sun was first observed in 1919. The agreement of that curvature with the prediction of General Relativity was the first big piece of evidence for General Relativity. However, the curvature near the Earth is much smaller even than near the Sun, because the Earth is very small compared to the Sun. Really big curvature of light by gravity occurs near the strange objects called black holes, which were also predicted by General Relativity. Therefore, the light ray from your laser will technically be bent by the earth’s gravity, but the effect will not be enough to be noticeable.
