BUMP

Dude... you bumped that three minutes after you posted. Give people time to spend with loved ones, feed the cat, etc.

What about the nature of light are you wondering is explained by the BB?

How light was created, how it started. According to the Big Bang that is.

No time for that Dan. Post constantly or be left behind...

What about Maxwell's equations of electromagnetism are you concerned about, messenjaH?------------------

? I just said...

Electromagnetism is one of the four fundamental forces of the universe. The four forces all split off from each other in the instants after the big bang.

messenjaHIt is not something that can be to easy to explain but I believe that science defines light as being from anywhere in the electromagnetic spectrum and not just in the common use of visible light.The Big Bang initially was a mix of matter and antimatter with a slight preponderance of matter over antimatter.I am not certain of the time that had to pass before electrons were able to coalesce into the structure of the atom but this is a neccesary first step since it is through transitions in energy levels of the electrons that light is emitted.Do not quote me but I believe it was somewhere around one to three minutes after the beginning.

Yes, messenjaH, I was responding to that.Light is described by Maxwell's equations. What is it about them that you don't understand? Do you even know what they are?ÑE = r/e₀
ÑE = -B/t
ÑB = 0
ÑB = m₀J + m₀e₀E/tThese are the equations in differential form. They also exist in integral form. That version is commonly used in the T-shirt: "And god said...[Maxwell's equations]...and there was light."Now, are you wondering where the fundamental constants involved come from? Why they are in this, specific combination? Is it the calculus? What?Be specific.------------------

Allow me to offer some thoughts, which I think might address some of the issues underlying your question. Or maybe I'm way off. Either way, I'm sayin' it.Ultimately, something will be left unexplained by science. I make no predictions about what that is, but it is certain that science has a limit (because it rests on the existence of natural laws, it can't step outside of whatever the "most fundamental" natural law(s) is/are).Let's assume that God started the Big Bang. Given that, does the Big Bang explain the origin of light, starting from a time in which there was not light? Yes, to the best of my understanding. I'm not your man to explain things from here, however, and you're asking about things on the cutting edge of modern physics. Don't be suprised if you don't understand. And certainly don't degrade science for not fully understanding at this time, either!If, ultimately, what you're getting at is: "Science can't explain everything", I agree with you, even if we disagree on specifically what it can't explain. Feel free to attribute that "something" to God. I don't find it necessary to attribute it to anything at all, but that's me.

I think Rrhain you are being a little unfair. yes, Messenjah is asking questions that he is not prepared for the answer to but you can still go a little easier than that.

A bunch of years ago "The First Three Minutes" was written. It is a small pocket book but still a fair number of pages all about the first three mintues after the big bang.What is astonishing is that we (not me, but the we that includes all of humanity) understand the intial start of the universe. What we don't know anything about is the time from about 10 to the minus 30th of so seconds after the big bang and earlier.However, light originates much after that. So you're question is answerable. But we'd have to know what you mean by light, as Rrhain suggests.If you mean light like from a flashlight I'd have to say you mean when the universe finally cooled enough to allow atoms to form and it became transparent. Before that the photons couldn't go anyway before they ran into something. I think that would be the point when it could be said that "light" appeared.Energy, as in the energy of the big bang and of interacting particles can produce photons which are the particles of light. Once there was enough clear "space" for these to run free we could say there was light. That it seems was about 3,500 years after the big bang (http://spsobserver.org/elegantconnections2.pdf)(BTW that URL is an article explaining where "light" and other things came from, it is NOT easy reading but, believe it or not it actually is a reasonably straightforward explanation of things. I did warn you this is not an easy begining point.Now back to what is not known -- before about the first billion, billion, billionth of a second after the big bang we donw't know. After that we know a lot.There are still difficulties after that of course. The "inflationary period" isn't to everyone's liking yet for example.
