Hmm, is that just me or is there that zero point energy coming into play again?Despite some initial claims of negligible or even zero momentum transfer, recent theoretical studies concur that material objects may acquire momentum from quantum vacuum. This can be explained qualitatively by considering quantum vacuum as a random fluctuating electromagnetic field (so called zero fluctuations) composed of propagating modes. Each mode possesses both energy and momentum, causing Lamb splitting of spectral levels, Casimir attraction of objects in an empty space and other mechanical interactions from nano to astrophysical scales. The total momentum vanishes if the counter-propagating modes cancel mutually. It occurs in all materials except magneto-electrics, which lack both space and time symmetries.
Its not just you. First and foremost on my list would be "String Theory," which physicist Peter Woit christened so bad that it's "Not Even Wrong" in his book of the same name.Giorgio wrote:On a different note, is it my impression or lately there has been a large increase in "theoretical" models in many fields and a parallel decrease in raw experimental data?
String "Theory" is entirely provable and easily tested. All you need is a particle accelerator the diameter of the galaxy.Giorgio wrote:Yes, I know him from his blog, but I didn't read that book.
String theory (which we should call String HYPOTHEIS and not Theory) looks also to me just a way to discuss about nothing, as nothing out of it can be predicted or tested.
I mean, for what is worth they could spend their time theorizing about the Flying Spaghetti Monster and obtain the same results.
Metaphysics is important, and has its place, but not in science.The FSM is NOT theory! It is FAITH!! His noodely appendage will smite you for your insolence!Giorgio wrote: I mean, for what is worth they could spend their time theorizing about the Flying Spaghetti Monster and obtain the same results.
Yeah, you definitely don't want a bunch of Pastafarians showing up on your doorstep, unless of course you like wine and carboloading...clonan wrote:The FSM is NOT theory! It is FAITH!!

So, basically string theory says the FSM has 10^500 semolina tentacles.The vacuum structure of the theory, called the string theory landscape, is not well understood. String theory contains an infinite number of distinct meta-stable vacua, and perhaps 10^500 of these or more correspond to a universe roughly similar to ours — with four dimensions, a high planck scale, gauge groups, and chiral fermions. Each of these corresponds to a different possible universe, with a different collection of particles and forces.[29] What principle, if any, can be used to select among these vacua is an open issue. While there are no continuous parameters in the theory, there is a very large set of possible universes, which may be radically different from each other.
