Because non of you idiots ever attended school, instead you wasted your time reading book about magic and now you have a lower intelligence than that of the average 10 year old.

"Really...

Could you please explain to me what a photon is?"

Sure, think of it as a little packet of energy that gives off radiation in the form of visible light.

So you are saying that these 'light particles' give off light? Cannot you see this is circular reasoning?

Thank you, kind sir!

Through equivalence, momentum can be expressed in many ways.

p = mv = mc = ħk = mcc/c = E/c = hf/c = hc/cw = h/w

Did I miss something? I feel... awkward...

You left out p = 1/((1-(v/c)^2)^1/2). Not that I believe anything Einstein had to say. After all, the Bible tells us that Jews are all liars:

For there are many unruly and vain talkers and deceivers, specially they of the circumcision: Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre's sake. Titus 1:10-11

Then, how can it be reflected by a mirror? After light hits a mirror, it bounces off. Light bouncing off of objects is what allows you to see. As light ricochets off an object, it will enter the pupil of your eye where it will then make contact with your retina. This causes your retina to generate an electrical current which is sent via the optical nerve to the brain.

So you're saying that light bounces off everything except retinas?

The brain then converts this electrical signal to an image.

What is that image made of?

The same exact process allows a camera to work.

So light bounces off everything except retinas and cameras, then?

Light is diffuse energy. Therefore, it won't put holes in you.

This doesn't look very diffuse to me:

Re: How can we see stars if they are "millions of light years" aw

So there is solid evidence that the earth is well over 6,000 years old. A bit of topic but if the earth is over 6,000 years old as it is a proven fact then as your date for the earth's age in wrong then it can be as old as some of these people are saying.

Since when does so-called "solid evidence" equate with "proven fact"?

Science doesn't prove anything. It just builds theories upon theories, a continual work in progress that is subject to being disproved at any point. The stated ideals of scientists require objectivity... chips falling where they may and all that. However, scientists are among the worst hypocrites and blasphemers... they cling to hopeless theories out of pride and avarice, despite evidence that clearly contradicts. The whole rotten scientific community is rife with intellectual dishonesty. And these are the people that we should listen to over God?

The Bible is not a theory, though. It is the written word of God as received by men, inspired and filled with His holy Spirit. Christians are not looking to see how the Bible stands up to each so-called scientific discovery or advancement as it occurs. Christians do not need to twist and dilute His Word to make it accommodate whatever secular theories are currently in vogue. We already know that the Bible is literally true!

The world would be a better place if scientists first tested their theories against the Bible! Of course, there's little chance of that given their sinful, prideful nature and their obvious hatred of God. In the coming reign of Christ, after the Rapture and after the Tribulation, I am sure that the world will finally experience true Godly science.

Wow, we agree on something. I think despite our "differences" that you and I could get along just fine. haha

Also, the equation p=E/c is relevant to me, since some homework problems require it to get the needed answer based on the givens.

"What you did is equivalent to determining the speed of a car by converting yards per second to miles per hour."

I see, It's easier on my eyes for me that way since I'm used to reading my speedometer in mi/hr, I apologize.

You're welcome.

Through equivalence, momentum can be expressed in many ways. p = mv = mc = ħk = mcc/c = E/c = hf/c = hc/cw = h/w. Did I miss something? I feel... awkward...

Yes, you missed the point completely. It's irrelevant how many ways you can come up with to express the momentum of a photon. All that matters is how you determine the momentum of a photon. And as I already explained to you, one does that with the frequency, which is the only variable relevant for determining the momentum that a photon has. I could have lived with you using the wavelenght instead of the frequency to determine the momentum, but using the energy to determine the momentum is rubbish. What you did is equivalent to determining the speed of a car by converting yards per second to miles per hour.

Now please stop wasting time on physics, as you clearly have no idea what you are talking about, and start doing some serious Bible study!

Re: How can we see stars if they are "millions of light years" aw

I see, so something which is energy, has no mass, has momentum. If it has momentum, it can strike things with force. So you are saying light has mass?

[AnAuthenticAtheist]

Re: How can we see stars if they are "millions of light years" aw

Don't talk nonsense. Every little child knows the momentum of a photon depends only on its frequency. p = ħk where k is the wave vector (where the wave number k = |k| = 2π/λ) and ħ = h/2π is the reduced Planck constant.

Thank you, kind sir!

Re: How can we see stars if they are "millions of light years" aw

The equation for the momentum of a photon is p= E/c, where c is the speed of light, p is the momentum, and E the energy of the photon.

"I guss the part that confuses me (I am just a simple country boy after all) is if light is pure energy, then how can photons 'push' things. I have a few childs toys at the Hutchins home, a 'Radiometer'."

Photons still have momentum, when a photon strikes a surface, it may be absorbed or reflected. In either case, momentum is transferred from the photon to the object whose surface is struck. In this way, a force is exerted on the struck object.

The equation for the momentum of a photon is p= E/c, where c is the speed of light, p is the momentum, and E the energy of the photon.

The equation for the momentum of a particle with mass is p=mv, where p is momentum, m is mass, and v is the velocity of the particle.


"So only the light from flashlights dissapate, the light from stars, which are merely little diamonds in the sky, reflecting sunlinght, can last forever. Interesting"

Close, the light from the stars does not last forever. The light they emit is just brighter at the source and thus will travel farther before it dissipates.

Stars light doesn't go forever or else eventually every star in the universe would be visible to us. Only stars close enough for their light to reach us will ever be seen much like if I shine a flashlight it is strong enough for you to see from a few yards away but it becomes invisible at greater distances. Same with stars only their light is stronger therefore visible from farther away from a flashlight.

Re: How can we see stars if they are "millions of light years" aw

Gravity effects EVERYTHING, not just things with mass, but everything.

So it also affects things that have no weight like electromagnetic fields? Weird, as not even atheists scientists seem to think that.

The last number I saw was that a photon, if it has any mass at all, must be less than 4 x 10^-48 grams.

And how does one determine that? I cannot imagine a weighing scale being that accurate.
