http://www.ted.com In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory may soon be put to the test at the Large Hadron Collider in Geneva).

    Saying that life has no meaning with the possibility of going to heaven is incredibly disheartening. The only reason you are good is to get into some kind of celestial country club? You can't enjoy life without the prospect of 'winning' an afterlife? What kind of morals are those to teach? Be good out of fear. It totally impoverishes and cheapens the beautiful, majesty of the natural Universe. There is an overwhelming amount of wondrous things in the natural world to fulfill anyone.

    I believe stupidity has reached critical mass in this comment section.

    this might sound weird, but is it possible, just possible, that every one of those strings, resonating at different frequencies, all are composed of the same type of "energy", all are united under a single medium of "energy particles" smaller than we can comprehend. Then, wouldn't we possible assume that that is God, and it would still support both science and religion an unite them under a single scientific explanation: String Theory.

    Gravity is the bent space time done in the presence of a mass according to general theory of relativity. Only impressive math skills you have to have. Tensors, derivatives, fields. Imagine a rubber sheet the Sun a cannon ball and the Earth like a marble rotating around it. There is not an attraction force per say like Newton thought although is very intuitive, but rather the Earth moves on curved space-time geodetic lines that Sun bends. It’s like it always chasing a valley.

    Same thing happens at small scales with the higgs bosons. They will never find it because “matter” generates itself at the smaller levels too and you always find something when you look at it because we collapse the wave functions into 3D reality. Consciousness is the computer.

    I think that the space is a calculation done by consciousness in order to interpret the data that comes into it. It is a mathematical function defined by the (LCS) consciousness system. Scientists are expecting to see the edge of the Universe and they will never find it because is all virtual and it generates itself as long as you stare at it.

    The universe is how it is because God spoke it into existence that way.

    If some of our ancestors were so stupid to accept the 'mysteries' of universe as a 'proof that indeed it is god who designed this world', we'd still thinking the sun is a handsome god driving his golden chariot across the sky ...
