eat one's cake and have it... how that is possible?

How did our universe begin? but simplifying the problem a little... what is the universe made of? ... of what stuff? Probably didn't begin its existence in a particular place because there was no initial void, no emptiness of original space, even NOTHING was!

In relation to the contemporary space can be said that every point is a place where the universe began its existence. So just our universe was only one and it was all over... magic moment in a grain of poppy. And what way was disenchantment? ... This is unfortunately the deepest mystery of science!

The most interesting is, however, as they explained... of which our universe emerged ... namely it emerged out of nothing! Of course now we know that "nothing" is wrong idea... NOTHING doesn't exist.

But even this peculiarity of cosmic soup bubbling with energy is a little too little for the enormity of our universe. And not only is our universe created ... additionally, remains what that was created... which is quite full-bodied soup!

So you can eat one's cake and have it... How that is possible?

    And when you talk of having and eating cake, think of how light is both a wave and a particle which is impossible and yet it is, and then you will see that it depends on how one observes it that dictates if it will be a particle or a wave. The same goes for the universe. It is everything and it is nothing. It being one or the other is all in how you look at it.
  • Jun 30 2013: Everything that science "knows" about the big bang are conclusions based on theory and mathematics. It is the best model available so far, but mostly it has not been confirmed by observations, certainly not direct observations. For example, assuming the theory is true, no one has or will ever measure the temperature of the universe at the moment when subatomic particles came together to form atoms. That part of the theory has not been confirmed, and cannot be directly confirmed. Similarly, what existed prior to the origin of this universe will never be confirmed by direct observation. There will always be a great deal that humans will never observe, and this leaves our theories open to question.

    Critical thinking requires that we understand how well we know what we think we know. One method is to categorize knowledge by the source of that knowledge. Some things we know by direct observation. Some things are very well confirmed by indirect observation. (Quantum Mechanics is considered an extremely well confirmed theory and it deals only with the invisible.) Some things that we "know" are very solid conclusions based on theories that are well confirmed, but the conclusions cannot be directly confirmed, perhaps because they are beyond our ability to measure. (For example, the speed of light beyond our galaxy.) Some physicists are claiming to "know" things that are the results of calculations, but have never been experimentally tested, either directly or indirectly.

    We will never know whether or not "nothing" exists. It is impossible to prove that "nothing" exists. Also it is impossible to empirically establish that "nothing" does not exist, although "nothing" may be incompatible with our best theories.

    The beginning of the universe can never be confirmed by direct observation. To some extent, this will always be mysterious. Some people find that tragic. I think it helps to keep us humble.

    After eating your cake, you have it inside you.

      Jul 28 2013: Best line in a good reply: "Critical thinking requires that we understand how well we know what we think we know." Although by that definition the number of critical thinkers in my life dropped some.
