String theory fails (Introduction)

String theory is an attempt to combine Einstein's relativity, which works on large objects, with quantum mechanics, which works on tiny objects, but has failed to do so for over 25 years. Quantum loop gravity has also not worked to combine the two theories. Will we ever get a combination equation to bring the two together. Perhaps we are not meant to get there!?-http://www.youtube.com/watch?v=wHHz4mB9GKY

DAVID: String theory is an attempt to combine Einstein's relativity, which works on large objects, with quantum mechanics, which works on tiny objects, but has failed to do so for over 25 years. Quantum loop gravity has also not worked to combine the two theories. Will we ever get a combination equation to bring the two together. Perhaps we are not meant to get there!? -http://www.youtube.com/watch?v=wHHz4mB9GKY--What a wonderful little video! I played it through twice so that I could note some of the gems:-"We know what a singularity is. A singularity is when we don't know what to do."-"The collapse of physics as we know it."-"Nature is smarter than we are."-"We don't understand."-And best of all, the stunning conclusion: "Quantum gravity is the name that we give to the solution to this problem. We don't really know what quantum gravity is." Substitute "god" for quantum gravity, and we can all dance together in the dark.

That is where faith comes in. Real faith is best(strongest)if not created by miracles.

Exactly. God prefers to be concealed, and challenges us to find Him. That is where faith comes in. Real faith is best(strongest)if not created by miracles.-That is something we can agree on.

rom:A wise man, George EP Box, said > > ... all models are wrong, but some are useful. > > Even yours David-Your opinion is accepted, mine is useful; but Smolin and Woit agree with me. I rail against the government/science complex all the time. Too much grant money chasing too little valid science. Lots of fraud.-http://www.guardian.co.uk/science/blog/2012/nov/02/scientific-fraud-good-science-In physics now if you don't do strings, what do you do? And what has it gotten?-See my entry of 15 hours ago.

String theory debate: no progress

Brian Greene's article discuses its place at this juncture in time:-http://www.smithsonianmag.com/science-nature/string-theory-about-unravel-180953637/?all&no-ist- "Looking back, I'm gratified at how far we've come but disappointed that a connection to experiment continues to elude us. While my own research has migrated from highly mathematical forays into extra-dimensional arcana to more applied studies of string theory's cosmological insights, I now hold only modest hope that the theory will confront data during my lifetime. -"Even so, string theory's pull remains strong. Its ability to seamlessly meld general relativity and quantum mechanics remains a primary achievement, but the allure goes deeper still. Within its majestic mathematical structure, a diligent researcher would find all of the best ideas physicists have carefully developed over the past few hundred years. It's hard to believe such depth of insight is accidental."- Read more: http://www.smithsonianmag.com/science-nature/string-theory-about-unravel-180953637/#V35...
