what you are referring to is not actually light, it is a type of radiation, it's called the background radiation and it was discovered in the 1920s by accident, just like every great discovery. this is the only remnant we know from the Big Bang. it is normal that such an "inflation" of the universe to leave a powerful radiation wave. (and I say inflation because the term explosion would mean that there was oxygen already outside the small point we originate from in which case burning would have further been possible and the universe wouldn't have cooled down so fast) it is constant and all around us. nobody ever said we can look all the way back, like even before the big bang, not at this point at least. scientists,right now can look back and prove the big bang...but no further. for more details visit this years Nobel prize in physics.

Not exactly. Remember that the density of matter was much higher early on. That matter was hot and interacted strongly with the light that existed. We can only track the light back to the place where the matter cooled down enough to let the light get through. In fact, that is exactly what the microwave background radiation is!
It turns out that it took about 300,000 years for the matter to cool to the place that light could get through, so that amount of time after the big bang is the earliest that we can directly see. However, the bumpiness of that background radiation tells us about earlier times because it tells us how the matter was distributed when the light started getting through.

That is exactly what astronomers are seeing (or not seeing) in space. Looking further into space is glimpsing the earliest times of this universe, and they are aware that there is a limit to how far we'll ever be able to see. In the very earliest moments of the Big Bang, conditions were so dense that radiation couldn't pass through, which is why it's loosely called "the Dark Age". It's not expected that we'll be able to see beyond this zone, to be able to "see" right up to the beginning of the Big Bang.
A common misconception is that the Big Bang "happened somewhere else", and we're looking at it as a remote, ancient explosion. In fact, the universe is homegenous and isotropic, meaning that things look the same no matter where you are in the universe. The light we see from "early quasars" in the far reaches of space were actually much closer to our present location at the time the quasars emitted light, but because of the expansion of the universe it took billions of years for it to reach us.

Good question. Here's the fact of the matter. We can see "back" to nearly the big bang, but will NEVER be able to see all the way back to it. The Big Bang created space and time. All matter and energy came after the first "tick" so to speak, of the cosmic clock.
A simple way of looking at it is this-----light, for example consists of discrete packages of energy called quanta. We can't detect quanta in any way, but in their interactions they produce photons, which are detectable. That didn't happen at the Big Bang, but afterwards.
How long afterwards? It's a meaningless question in cosmology or physics. If something can't be measured or described in any way, it doesn't exist. So what was there at the micro-micro-micro-........instant of the Big Bang? Nothing. And what was there in the next micro, micro-.......instant? Nothing. Not until detection became possible as matter and energy separated out from the stuff of creation could anything "be".

For an everyman's answer to the theory of the Big Bang and Black Holes you should read from the world's foremost expert on the subject Professor Steven Hawking, he holds the Chair of Mathemetics at Cambridge University, the same prestigious position held by Sir Isaac Newton. Have a read at the following website, it will give you some of the information you seek. Professor Hawking writes in a simple to understand style you may like to find his book titled "A Brief History of Time" in your library, this website is an extract from it, a great read from a great mind.

well actually no. sense we are being theoretical you can fallow that light emeted from the big bang and always take a picture of it. you would be on the edge of the universe to take this picture. given that you know where the big bang took place (if it did) As of where we are you could not see the light from the big bang theory from earth. It has passed us by(if it happened at all) Like I said you would have to traval to the edge of the universe to see it.
Oh I see where the cofusion is comming from. If you are on earth and you wave your hand. Somebody 1 light year away witha big telescope watching you would not see you wave your hand for one year. The light comming from you waving your hand travels at a certain speed. so if you were able to jump 13 billion light years and get a telescope and look at earth you would see 13 billion years ago what earth was like. you are not looking out from earth and seeing earth 13 billion years ago but seeing other planets 13 billion years ago with the telescopes. I don't think they can do that short of thing you would have to set up some short of reflector pointed at earth 6.5 billion light years away and then it would take 6.5 billion to get to the reflector and 6.5 billion to get back to earth.
hope this helps

The early universe was only time and space. There was no gravity,no strong or weak forces and no electromagnetism.
Before light emerged [electromagnatism] there would be no way of determining with a telescope,what existed at that time.
It probably will never be possible to look back and see the origin!
Matter surely preceeded light!

Present theory is based upon the explosion of finite particles into infinite space create what we know as the universe. However, this I feel to be impractical given the infinite numbers of universes and dimensions that are out there. Think of the universe as a bubble, in the beginning it was practically empty. An impact with another universe bubble created a rift between the two causing the content of the one to spill into the other, over time the bubbles drifted apart and the rift was sealed. The new matter within this bubble began to move away according to the fluid dynamic principals and the creation of the universe began. The rift or area of contact would have all the characteristic of an explosion due to impact and would always be visible as a single frequency within the universal constant. This theory would also explain why there have been signs of matter within the universe that appear to be older than the universe.

i do no longer help the belief. As you're saying the branches of Physics, arithmetic, and topological astronomy besides as different sciences are just to a lot to place all of it mutually. submit to in innovations the vast bang is basically a thought and not a actuality! It won't manage to be shown as a actuality! Even Hawkings won't manage to get lower back to show 0, and he on no account will. the reason being he's calling for the commencing up. So, enable us to now placed the vast bang on the shelve for a minuet and enable us to seem on the expanse of the universe as continually being there. no longer each thing it fairly is in it. yet an expanse that has continually been. we've a commencing ingredient! an empty eternal expanse that has continually been there. each thing interior the expanse we see right this moment has order This we call the universe.It keeps to enhance interior the eternal expanse. each thing follows all of the regulations of physics, and math. So purely how did the three dimensional universe as all of us comprehend it commence? all of us comprehend from Einstein's formulation E=MC^2 that we are able to get power from remember. We additionally comprehend from Newton's regulation of physics that each action has an equivalent reaction. So, taking dynamic power one ought to create each thing and commence the action of each thing created interior the expanse with order. is that this logical? specific! Is it authentic? It must be because of the fact we proceed to discover greater approximately it making use of the guidelines of physics and arithmetic. So this could open the biggest question of all, purely who or what created it? This my chum i'm going to flow away as much as you to come back to a decision.

From what I've learned about it matter started all over the fabric of space not in one particular spot and the expansion is from the stretching of space itself.
Here is an interesting page that explains it.
