if  the whole universe is made of energy then why it is not freely available?

Who said it is not freely available? Only thing is:-All the energies are governed by the Law of Conservation of Energy. According to this Law, the total available energy is constant, and energy can neither be created, nor destroyed, but one form of energy can be converted to another form. The cost involved in energy is the cost incurred in converting one form of energy into another form.

It is theoretically possible to make anything a gas (including that).  It would take way too much energy to do so though.

No one anywhere has the answer to your question, or even if there was any "thing" before the Big Bang. The religious crackpot fundamnetalists certainly don't have the answer! By definition, the universe is everything there ever was, is now, or ever will be. At the instant of the Big Bang, all space-time and energy that will ever exist was created.\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com

where did the first energy came from, to produce the BIG BANG. Becaseu there is that law, that there is no perpetum mobile, meaning, that everything needs the first impulse of energy. further, energy can be exchanged and such, but not produced from nothing. so how could the big bang happen out of nothing.

The Universe is boundless, yet finite.  So you could never exit the Universe.

did someone sleep in science class or do they not teach the laws of thermodynamics anymore, one of them states that energy cannot be created or destroyed. pick up a science book and read it some time.

Energy is created.\nPhysicists currently believe that about 75% of the energy in the universe exists in a form known as dark energy.\nThis energy has a constant density over all space regardless of what the space contains and so the total amount of dark energy increases as at the same rate as the increase of the volume of the universe (which is expanding).

it has unlimited space in which to move outwards. Therefor the radiation from the big bang is the  first outward layer of the expanding space, then everything else. Turn on your tv to a snow channel, that is space radiation, and from our sun. It shows up like that. The concept of unending universe is hard for a human to grasp. We live in a finite life.

In all actuality, your question makes no sense.  If you were to take out all the "space" in matter, there would be no matter.  Matter is basically made out of energy and forces interacting with each other.  If you compressed the universe into the size of a refrigerator, you wouldn't have matter anymore.

Energy cannot be lost in a closed system, when there is strictly NO interference from outside sources.  So, energy can appear to be lost on Earth, as it is not a closed system, however looking at the Universe as a whole (which is most likely a closed system), any energy that appears to have been lost is still there.  Its just that the energy, whether as heat or light, can be "stretched" so much across the vastness of space, that it can appear to disappear.  \n\nSimilar to feeling the heat from a candle.  When you are close to it, the heat has only moved a small amount and is reasonably concentrated when it reaches you, however stand a lot further back and the heat disperses and you will notice that you can't feel the heat as well, if at all.

The universe contains all the matter and energy that was ever in it.\n\nSo, going from the Big Bang Hypotheisi, it is reasonable to assume that there was a flash of light (energy, which must remain within the universe) at the time of the explosion.\n\nGiven that light travels at a constant speed, and the universe is about 15 billion years old, the universe is an every expanding sphere of space, 30 billion light-years across.\n\nWhilst it may not go on forever, you'll never reach the outer  boundary!

As long as we understand, energy can take different forms but it can not be destroyed.  It can be converted to mass, and vice-versa.  There are other forms of energy such as light energy, chemical energy.  It seems that energy is exhibiting higher dimensions of space and what we see within our 3D world is translated to our braind as energy.

Very good question it is.\nbut\nPhoton is pure energy is it not?

Let´s contemplate no God:\nGod does not exist, so the universe is only a random and everlasting energy and matter transforming process, we are a tiny piece of matter which exist only because of a random event and we are only waiting for another random event to stop existing ( I meant: to transform into another thing ), then the universe and us have no goal or reason to exist.\n\nI don't like it.......God forbid!

Actually there is only one universe which encompasses everything: "All matter and energy, including the earth, the galaxies, and the contents of intergalactic space" - http://dictionary.reference.com/search?q=universe\n\nThe earth is part of a galaxy which we call the 'Milky Way'.

The correct answer is that no one knows.  We don't even know what most of the universe is made of (right now it's being called dark matter, because all we know about it is that we can't see it).\n\nIf I had to make a bet, I would go with total energy equals zero.  \n\nThere is a lot of matter in the universe, as everyone is saying, and that makes for a lot of mass energy.  But, the flip side is that there is a lot of mass in the universe, and that makes for a lot of negative gravitational potential energy.  It is possible they cancel.

"Matter can be neither created or destroyed" is an old saw from pre-Einstein physics.  Matter is continually being transformed into energy in every star in the sky in accordance with E = mc^2, so in that sense, there is certainly less matter in the universe now than when I started typing.  However, (I think) the equation is reversible, so the energy can be transformed back into matter, so maybe the answer is there has always been a constant amount of matter/energy in the universe.
