Energy where does it come from?

  1. May 3, 2012 #1
    Okay... For he last 3 months I've been studying energy back to back with undergoing all the laws that supports it.

    Two famous laws "Thermodynamics" + "Law of Conservation" both state that ENERGY CAN NOT BE CREATED OR DESTROYED, ok makes sense because so far everything on this universe follows it. But then I ask my self then where did it come from? Now philosophy is applied to this question to give a reasonable answer.

    I do believe in those laws so far they've been the fundamental laws of physics. However, we use physics mostly to answer questions now the BIG question is left un answered where does energy come from?

    Since now they believe in the BigBang"Universe from nothingness" then that violates the laws since energy can't come from nothingness?

    Im left out here confused in the end of the day wondering why? or how?...

    I believe their is something missing from the equation for something not logical at all...

    Give me some sense people I'm kinda lost. Have people thought of this before or just choose to neglect it?

    Hi Hypo! :smile:
    The big bang theory doesn't say what caused the big bang.

    It only says that there was a big bang, with energy.

    Okay did energy come along with the "big bang" or was it created by big bang? Im really confused at that point what about you?

    I mean what DO ALL OF YOU think about energy and where it came from? Honestly its just mind blowing when you study more about it.

    with the theory, yes :smile:

    How can they describe energy then? I mean where did it come from? Was it just there?

    Or maybe it came with the bigbang "created" before or something because it just dosen't make any sense at all...

    WE. DON'T. KNOW. (gasp, shock, faint! :eek: :surprised: :cry:)

    Aha.

    We don't know much about energy and its origins and such yet we talk about it as if we know all about it. Really confusing :uhh:

    Why does it matter where it came from?
     
  10. May 3, 2012 #9
    Mainly because we have so many laws about energy yet we don't know its origin?

    If this was the attitude towards every question, science would not exist.

    From my ignorance, there are theories which allow the existence of our universe's energy out from nothing.
    So the point is not so much, "where did the energy come from" but rather "why does something exist rather than nothing"?

    True, I look at the laws of conservation and thermodynamics and I ask my self this question always. All the laws are true but dosen't make any sense at all! My be there is something missing in this puzzel after all we just now a tear drop of water from a SEA of things.

    I believe that energy was created at some point or at least formed from something because BEING there is just not logical to my mind...

    I was never more confused in my life about a question and unfortunately no one knows the answer I think i'll take this confusion with me to the grave unless they find an answer over at CERN or somewhere...

    Again, so what? The origin doesn't affect the functionality of those laws.

    True, but as long as it is just the attitude toward the non-scientific ones, science will be fine. :smile:

    Could be functional under our understanding. Maybe it functions another way in theory because we haven't understood the "OTHER" side of energy since it not completely understood so far.

    Let me ask you this. What is energy? I don't want some mumbo-jumbo about what you think it *might* be, I want to know what it is according to your understanding. No speculating! Just your current understanding of what energy is.

    My current understanding of energy is that "thing" that is able to do work in a physical system it also that "thing" can not be created or destroyed. Its a constant value that is transferred from one from to another.

    That to me is energy.

    But between all the things in physics its the most that doesn't make sense... Not created Nor destroyed..?

    Hi. We find and use hidden or potential energy for our purpose for example:
    We use coal for fire. Coal store chemical energy inside. We release and use it.
    Energy of light from Sun was stored in coal long time ago.
    Nuclei core contains atomic or actually coulomb energy inside it. We use it.

    We can find or transform energy but cannot create energy.
    Regards.

    That I understood and its the simplest thing about energy honestly... But I can't believe that honestly because so far I believe energy was created at some point and released with the bigbang. That dense heat itself is massive amounts of energy so as matter was created from that energy aslo ani-matter that heat was increasing constantly and before the bigbang there was nothing so I guess energy was created at that point or transfered from a previous source before the bigbang that means there is something before it huh? Everything contradicts the other thing...

    If they would understand the bigbang more maybe we could shed some light to this... I believe in the bigbang I believe in energy so as matter but I do believe they were created. Not constant and was "THERE" for all eternity.

    Honestly guys do you think energy is like that there no begging and no ending? We don't even understand it properly...

    Energy "is", and will always be. It is that which drives this universe.
    Of course we do not know where it originated from, as we have only been around for a little while, if we knew the answer to that question we would inherently know the answer to the other 1000 questions that boggles us today.
