I cannot answer on Jernej's question directly. But I can answer with question. If the space was born in big bang, then the whole energy was made there, but then we come to another question. What caused the big bang? In these areas of science there are always more questions then answers and that make it hard to explain.
I would say that perhaps we are still not clever enough to answer all the questions. That is fine with me, because it makes our life interesting. Teacher
Energy is used in pysics and other sciences. So it may come in many different forms: mechanical energy (which may be kinetic or potential), heat, radiation (including light), electrical energy, chemical energy, nuclear energy, and others.
So I think energy is one of the most important things in the world.
I am glad you are here. This means that you are doing some extra English work at home. Our blog is just another way of communication between us. My plan is to post tasks here for you from time to time. It will not take much of your free time, but I hope it will help you improve your command of English. Your commitment will also be awarded according to our agreement at school. I want you to communicate in English. Do not forget to be polite and always sign your comment with your code; "anonymous" posts are not welcome. Teacher

I agree with matej!
But if the energy never vanish, how was she "born". What made the first energy!

Matjaž, do you read the question before you just copy and paste your comment?
