At the big bang light/energy was released. In an expanding universe will the light/energy released?

The big bang implies a ball or singularity that contains all the matter and space in the universe.

This doesn't make sense,the entity would have nowhere to exist and no way of knowing when to blow up.

The universe resulted from a finite potential some time after time zero.

A single space-time pulse of minimum size and duration initiated the universe.

The pulse continued, accelerating radially outward for about one-thirty billionths of a second,and stopped accelerating when the speed of light was attained.

At this point there was a 2 cm diameter sphere with all the ingredients to evolve into the universe we see to-day.

It was at it's maximum density,with no gravity,no electro-magnetic radiation and no strong or weak forces.

It contained a quantum effect,quantizing errors that enabled the universe to eventually produce matter and everything we experience to-day.

All matter within our universe is the same amount from the day the big bang occurred to the point it has expanded thus far. Our universe may seem infinite but that is only because we can't see the edge, in fact, our universe is still expanding and how long it will go on is a mystery. Some believe that the reason behind this because of dark matter which is forcing our universe to expand and then eventually stop or slow down but new evidence has revealed that it might be dark energy forcing our universe to expand, but the difference is that it isn't stopping. It is continuing to stretch forward and most probably will split our universe or continue on, and if this the case then our universe is infinite in the fact that it wont stop expanding. This will eventually lead the universe to an acceleration point where it will be moving so fast that it will possible hit light speed. This means even if we were to reach light speed in a ship we would not even touch the edge of the universe because it is moving at a constant speed beyond our own. It's like if the universe was 100% we would only be 99.9% since 0.1% is the gap we would need to clear to reach the edge but this will never happen. But if we were to clear it, we would most probably enter into the void. Since it's a hard thing to imagine how the universe started, it would be equally hard to imagine before the universe because before the universe there was the void. It essentially a space of endless nothingness or an absent space. None of the fundamental laws of normal space and the universe exists, this includes mass, energy, atoms, light, even space and time. It is because of this scientists question how something came into nothing when there was nothing to begin with. It is a contradiction of existence. We would need to understand how this works before we can prove everything else. I hope this was informative.

Rather like the first answer you received. There was no here there or anywhere before the big bang. the BB created the space we live in as well as the energy/light/matter etc that is inside this space. There is no edge to the universe in the normal sense of the word as space itself only exists inside the universe it it part of this universe. outside this universe, has no meaning except in the sense that outside is not a part of this universe. So if something is outside the universe, it is not a part of this universe and does not have to follow any of the rules that we understand, can measure, see, feel etc. As far as we understand, we can not interact in any way with anything outside our universe. We can only ever know, measure, comprehend what is inside our universe. So no light/energy etc can ever leave the universe not enter from outside, it is a closed universe. (at least that is current thinking) So everything that is in it now was always in it and will always be in it. from the beginning of time to the end of time. Time itself started with the big bang, there was no time before that. If the universe has enough matter it will at some future time start to fall in on itself just as it is now expanding. When it all comes to a crashing singularity again that will be the end of time. If there is not enough matter/energy in the universe then it will expand forever and there will be no end of time. (for expansion also read cooling, as the energy density is reduced) (for collapsing also read heating, as the energy density is increased)

Overall the distribution of energy in the universe is fairly even, but it is not entirely smooth, it is a bit lumpy, eg, planets, stars, galaxies, galactic clusters etc. even the background thermal radiation remaining from the BB is uneven, that unevenness is currently being measured and observed with a view to gaining a better understanding of our universe.

The BB did happen in one spot , a singularity. The energy of the 'explosion' filled the fledgling Universe with very HOT matter. Because the Universe is expanding, the initial high temperature has to be spread out further and further. The temperatures of stars is a later addition caused by atomic fusion reactions but the interstellar space also has a temperature. Due to the expansion, the background temperature is about 3 degrees K.

You are suffering from a misconception. The Big Bang was not an explosion that occurred somewhere "over there" and released matter and energy into space.

The universe is evenly, uniformly filled with matter and energy everywhere. There are no void places into which the matter and energy are streaming. Instead, the universe is uniformly filled with galaxies everywhere, and the distances between them are getting larger. The "Big Bang" is simply the name we give to the early universe, when those distances between things were all very small and the universe was very hot.

So your question does not make sense, because there was no place of "initial release." Light waves and energy are everywhere in the universe.

xc Yes, very much like the answers before, energy is everywhere in the universe: 3 Kelvin !! This energy is said to be the remainder of the big bang. however, something in the first answer is wrong: There actually are giant voids in the universe, but the voids are only voids of matter, you'll find the basic energy of 3 Kelvin there, too, the exact value is 2,73 Kelvin Btw it is not quite even: there is a small unbalance of 0,03 Kelvin into different directions.
