Since energy can neither be created or destroyed, does this mean the universe is eternal?

Question

the universe was created by energy (or god if ur a christian like me), but since energy cannot be created or destoyed, does this mean that the universe was never created and never will be destroyed?

Answer 1

Well hey there...

Are we not getting our stories a bit confused here?

Let's put it this way...

All the matter that is out there will always be there in one form or another...how about that. Don't agree just to agree... you must understand that as you move from one type of matter to another you either add energy to get there or release energy during the change.

Now if the energy is dissapated throughout space, it is kind of like not here anymore, in that it is spread out so thinly that it is hard to detect it. But, and this is important, it is still there.

All of the matter that is in space will stay in space, no matter what anyone tells you. Because, there is no where else for it to go. Most observers see something like a bomb blast and say that what ever was there is gone now... It is not. It was just subdivided into millions of tiny little bits and finely spread out so we cannot easily recognize it as we did before.

It may be thought of sort of like the way wheat chaff is tilled back into the soil and goes away...but it doesn't. the wheat chaff actually changes into soil, soil nutrients, and worm food.

As regards your religious convictions...Everyone has to believe in something...No problem. Just don't let religion interfere with a probing mind.

Answer 2

Energy cannot be created or destroyed by natural causes. Christians believe that the universe was created supernaturally; obviously, it would require a supernatural action to create or destroy energy.

According to natural science, the entropy level of the universe is constantly, inevitably increasing. This means that the energy was at one point highly focused, and is now becoming more and more uniformly distributed. Once all of the energy in the universe is evenly distributed, the universe will be an inert mix of uniformly distributed energy -- nothing can happen after that, because no energy will be moving.

Obviously, Christians think that God will intervene and the universe will end long before that, but left alone, that is what would happen.

Answer 3

Energy cannot be created or destroyed, but Einstein proved with general relativity (E=mc^2) That mass and energy are relative to each other, matter is essentially made of energy. The universe started with the cingularity. A infintismal point of energy. This was the big bang. If all matter was converted to energy (heat, kinetic, stored, chemical) there would be no stars, plants, nothing but energy. However, the universe will always exist in one form or another

Answer 4

Read up on the idea of a zero sum energy universe, or words to that effect. I take this to mean that energy can be positive or negative, rather like particles and antiparticles, and just as those particles can come into existence and annihilate each other again without violating any natural laws, so positive and negative energy is constantly in balance - it sums to zero - and it can exist at random and uncaused without violating any laws of nature. Specifically, a universe could come into existence without it violating the law about energy being neither created nor destroyed, provided it satisfied the zero sum critieria.

This is undoubtedly all wrong, but it's something you should read more about (and so should I!)

Answer 5

The universe will one day reach a state called heat death, where everything is the same temperature so nothing interacts any more. This is the law of entropy.
The big bang was in effect the instant creation of all the energy in the universe and it had to be caused by something. The causing agent had to be more powerful than all of the energy in the universe. I'd call that God.

Answer 6

Energy can't be created or destroyed but it can be changed. The way the universe is constructed in the future and how it's been shaped in the past are probably vastly different form it's current matter energy balance. It is also probably way beyond the current feeble human attempts at contemplation to understand.

Answer 7

The universe is endless and eternal regardless of energy. The universe had no beginning and will never end. There is nothing bigger than the universe. It is made of nothing, but it contains everything known and lots of unknowns. It has no, nor does it create, energy. It is nothingness to the max.

Answer 8

The latest observations concerning the size of the universe seems to show that it is expanding at an accelerating rate. No one know why this is true, if the big bang theory were right the universe should be expanding at a decelerating rate. The fact that it’s expansion rate is increasing means that their must be external energy coming from somewhere to “fuel” this. The question is where?

Answer 9

Scheiße....it's a ittle more complicated than that...but yes energy can't be created nor destroyed but there are many other(i don't know the right way to put it)shall i say atoms,forces?(not quite sure)that form the universe that can either damage the universe but not completely destroy it.i'm sorry that's the best way i can put it.

Answer 10

What Einstein means by that (or what I've inferred), is that there will always be the same AMOUNT of energy. If energy is destroyed, then more energy MUST be created.
