Light

What is it?

Why does it move?

Why is the speed of light what it is?

Discuss, add more questions, etc.

 

Could it be energy im not sure [Not up to date with phisics]

Im not sure on how it moves good question.. Somone answer that i would like to know.

Again im not sure ><

 

Light is the form of energy that fuels our life. It moves so we can live and use it. The speed of light isnt that fast, although it may seem that on earth think of how vast space is, and light seems slower than a snail.

Why are all your questions so eaasy?

 

Light is energy, but what is energy?

I didn't ask WHY it moves, but HOW.

I didn't ask about your thoughts on how fast it was, but rather, why it is the speed that it is.

 

In my opinion, Light is the rays illuminating from the Plasma in Stars. It's density is the reason we can SEE light. Plasmiac Energy, sir. :]

As the stars get older, it gets larger. As these big balls of Plasma get larger, more light comes from it. It moves because it has no choice. Unless the existence in a time vacuum suddenly stopped, Light would continue to move.

The speed of light is what it is because of the Mass majority of stars. There are so many Stars that the Plasma (Or Light) that illuminates from the stars combine and when they connect, their cores are combined which only makes them go faster.

Therefore, Light can and will only move faster as time progresses. I'm pretty sure it's approximately 186,600 Miles per second .. Pretty fast. :]

Not sure if that's all right, but it's a start! :]

 

But what are these rays?

Why does it have no choice? What forces it to move?

The speed of light has been shown to move at a maximum speed that appears to be unchanging on the macro scale. What sets that limit?

 

Light can only be explained as a variable in my opinion.

much like dividing by zero

 

Light is a constant, though, and dividing by zero is an impossible operation.

 

Those rays ARE the energy .. Unless you're trying to break down the components of the question ..
The weight of the Energy IS what makes it move. The weight pushes it .. A human might not be able to feel light touching them other than near the eyes, but it has a weight most likely undefined by any scientist ..
Uhm .. The amount moving at a time ? It's not like there separated into segments that move at different times and different motions .. I think ?

 

And what is the energy?

Weight is related to gravity. By that logic, no light should escape from the Sun, but should instead concentrate in its center.

The speed of light is constant, but what I want to know is why it is 300,000 km/s.

 

Well i learnt this in science the other day, Light is as you know the fastest thing in the galaxy, i know how it moves generally, all light comes from the sun ( natural or UV light ) and is reflected off things such as stars. In reality stars arent shiny thier just reflecting the sun's rays

 

You're correct as far as the sun goes.

Guess what? Stars are also suns. They shine too.

 

Light is a form of energy, it moves away from the sun because of the temperture of the sun, since the atoms are moving faster when heat is provided. Once the light begins to move it moves at a speed higher then many other things, because it has such a small mass, not many gravitional pulls can capture it. How they determined the speed I don't know.

Although the speed of light is constant in inertial frames of reference in special relativity, the speed of light can change based on its position of the frames. Which means it can be slowed down and speed back up. So in special cases speed's constant can be changed...

 

If light enters the atmosphere of Earth, it slows. Once it leaves the atmosphere, it resumes its normal speed. Therefore, the temperature of the Sun has nothing to do with it.

 

Of course not, I am just saying that the sun is releasing the light as a form of energy... I may have been unclear when I typed it.

 

But what is this energy? What composes it?

 

Ive got another question, is everything that we see a reflection that light produces? or is something ACTUALLY that color not just the way that light reflects off it and we receive it?

 

Yes, this is true.

 

The light itself is radition/energy coming from the sun from the energy that is let go after fusion and fission. Or one or the other I can't remember...

 

Speed of light is 299,792,458 m/s (about 186,282.397 miles per second)
energy is a scalar physical quantity that is a property of objects and systems which is conserved by nature. Several different forms, such as kinetic, potential, thermal, electromagnetic, chemical, nuclear, and mass have been defined to explain all known natural phenomena.
that's what i got from wikipedia ^_^
PS:i bet you know all of this
