Btw, i never thought to define darkness or light. What is light? I seriously dont know. What is it made up of?


Naming it a "photon" does not really tell you what it is.

Light is a vibration. What it is and how it vibrates is a good question.

wiki:

Light or visible light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight.[1] Visible light has wavelength in a range from about 380 nanometres to about 740 nm, with a frequency range of about 405 THz to 790 THz. In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.

Primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarisation, while its speed in a vacuum, 299,792,458 meters per second (about 300,000 kilometers per second), is one of the fundamental constants of nature.

Light, which is emitted and absorbed in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.

Perhaps darkness is also electromagnetic radiation but not the kind we can see.

What is light?
Light is awesome, it pays my bills.


Light is the energetic interaction between electric and magnetic fields.

If it were it would have vast ramifications which are just not seen . . . ie its not.

Can all radiation be seen as light? If not, how is it seen and detected?


How does light pay your bills?

All radiation is either light of various wavelengths or particle decay from the weak force.

Most wavelengths of light cannot be seen with the human eye, the cells in our eyes are just not sensitive to most frequencies.

I work in radiology!

I work under fluorescent light in an excruciatingly hot kitchen. Blood, sweat and profanity pay my bills.

Perhaps darkness is simply mass occluding the propagating EM fields.

We know that light exists.

What is darkness?


absence of light

That has been stated a few times.

If light did not exist, and never existed, what is darkness?

In most cases, light is heat, dark is cold :P

everything exists in duality in the universe....there cannot be one without the other...they are part of the same whole

Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it.
Terry Pratchett

Darkness is therefore what exists before the light

Light is knowledge and information....
darkness is the lack of knowledge and information.

Good one.

Light is a frequency.

Dark is lack of or a lower frequency.
