Electromagnetic wave, energy and universe

  1. Jun 17, 2011 #1
    All electromagnetic waves carry energy. We kno that most of the electromagnetic radiation escapes the boundary of the "physical(corporeal) Universe". Therefore, much of the energy is radiating out to the voids spreading beyond material universe. Thus, a great amount of energy is lost irreversibly making the material universe "cold" in sense of energy content. Could this scenario be the end of the Universe just as entropy death could be the likely end of the world?

    i dont think the science community has settled on the "shape", let alone the "edges", of our universe.

    What is this, and how do you know this?

    The universe must end somewhere; there cannot be infinite matter extending the infinities of the space. I kno its not proven the universe is finite but, dont u think intuitively that universe must end somewhere although we are not capable of seeing its boundary.
    Nice reply thou.

    Intuition has nothing to do with this. We have seen from history that our "intuition" has been proven wrong so many times. So falsifying something simply based on intuition is invalid.

    I would still like to know where you come up with your initial scenario. Please do not ignore that request because it will determine if this is a valid discussion or purely speculative.

    Pure Intuition. In the absence of any evidence, we are always forced to speculate on basis of our previous experience. This is how science works, using the pattern to predict things. An infinite universe will mean infinite matter which is unconceivable by our current understanding. Our solar system has boundaries, so does the galaxies. By same analogy, universe must be finite however vast it is.

    This is some really speculative nonsense. None of the available evidence supports it.

    Nice link.
    But i doubt the cyclic cosmology is true because it violates the entropy law. If the theory is true, it would destroy our concept of time; the infinite loop of time would mean no starting and end of time. Big bang(more successful theory) says time has a beginning but no end.

    There is not an absence of evidence regarding cosmology. Maybe you should actually learn some of it first.

    Again, intuition has been proven wrong. You haven't used any kind of valid references to justify your scenario. This makes this thread highly speculative, and thus, in violation of the https://www.physicsforums.com/showthread.php?t=414380" that you had agreed to.

    This thread is done.
