I think that energy conservation appears in many guises, but only works if you chose the appropriate version and apply it corrrectly.

I also think that energy is not a substance that can be isolated from a body or passed directly to another body.

As a matter of interest, you have called yourself the Believer.

What exactly is it you believe?

Science is not about belief.

If energy can not be passed directly to another body then according to quantum mechanics, why does an electron absorb energy to jump from a lower state to higher state and release energy to fall to lower state. If an electron releases and absorbs energy then it must be a substance or else how can something be released or absorbed?

And regarding your question about what I believe is a matter of a different topic altogether. But since you want to know then I must tell you what I believe. I believe the sun will rise tomorrow again. I believe I will reach my destination when I get into my car. I believe I will be alive for many years to come and that's the reason why I make plans for the future. I believe science will one day find, if not all but many of the answers to the questions of the origin of life and the universe. Everything starts with a belief. A belief to know the truth, to reach a conclusion, to find something, to go somewhere, to meet someone or do something. Everything is based on belief in the first place and this belief is what makes us humans move forward in life. So that's what I believe.

So do you believe?

It's not a physical substance. It's a property of things, i.e. it's a concept. (Like color or height. Being red or tall are not physical things, and you can't touch them, but the physical thing can be red, or tall)

The law of conservation of energy says that energy can not be created or destroyed but changed from one form into another or transferred from one object to another. By this definition it does not seem energy is just a property of things, but a real thing that exists in the universe. What do you think?

Hello  guys!

I am confused about the concept of energy. I have read that energy is the ability to do work. But this definition of energy seems incomplete to me. I wonder what exactly is energy. Is it a physical thing? can we see  it? touch it?  does it exist in matter as an invisible thing? Also the law of conservation of energy says that energy can never be created nor destroyed. So what is this thing called energy that can't be created or destroyed?. Can anyone please clarify this concept to me? It would be of great help. Thanks!

Hello friends!

I have a question about light. We all know that we see objects because they reflect light into our eyes. But we never see the actual light. So my question is why can't we see light. Or can we in fact see light. If so, how?
