About Reality Check,I'm no theologian, lpetrich. Au contraire, it was you who referred to intelligent design on the multiverse thread.
Farsight, those "arguments" are both ad hominems.So says the guy who started the multiverse thread.
Empty assertion. How would you be able to tell whether it is or not?RC: the universe is not some computer simulation!
Why is it that JREF is infested by cuckoo-in-the-nest suckers who believe in woo with such utter conviction that they reject simple straightforward relativity backed by Einstein references and hard scientific evidence? Answers on a postcard please.
Quite correct.People don't reject simple straightforward relativity. They reject your frequently erroneous misunderstanding of it.

I will nail you on your curved space error, ctamblyn. You would be best to concede now. People think more highly of people who say Sorry, my mistake. They don't think highly of people who demonstrate insincerity and keep digging themselves into a hole.
Anyway, like I said, time for bed, so mañana.
Sure. Let's make sure we remember where we are in the morning.
1. I claimed that spatial sections through the Schwarzschild geometry have negative curvature.
2. You claimed that it wasn't actually spatial curvature.
3. I showed how GR predicts a departure from Euclidean-ness in the spatial part of metric, using a measurement which doesn't depend on clocks.
4. You tried to claim that my rods were dependent on the motion of light through space.
5. I pointed out that many choices of rod are possible, not just light-based ones, and all will agree because they are all responding to the same curvature of the same space.
For a ruler, just to avoid confusion, I will use a near-monochromatic source of neutral delta baryons, and measure the distance they need to travel before half the the particles have decayed via the strong force. That way we get a perfectly good ruler without needing to appeal to electromagnetic interactions.
Wow - a Nobel prize waits for you Farsight with your amazing proof that the universe is not a computer simulationRC: the universe is not some computer simulation!
!The fact is that computer simulations can be run in parallel with differing parameters so the simulated reality hypothesis implies a multiverse.Simulated reality is the hypothesis that reality could be simulated—for example by computer simulation—to a degree indistinguishable from "true" reality, and may in fact be such a simulation. It could contain conscious minds which may or may not be fully aware that they are living inside a simulation.

A quick look does see the usual rants, e.g. thinking that an established scientists like Jim Baggott does not know about the purpose of peer-review (as a filter of obviously wrong science). Instead John Duffield gets a bit paranoid by accusing peer-review of "muzzling the press"!It's the usual mix of rants against the establishment, multiverse theories and Higgs mechanism, combined with his pet ideas about general relativity and electrodynamics.
.Pair production refers to the creation of an elementary particle and its antiparticle, usually when a photon (or another neutral boson) interacts with a nucleus or another boson.
This is basic physics - the uncertainly principle means that any particle can become a particle-anti-particle pair.Two-photon physics, also called gamma-gamma physics, is a branch of particle physics that describes the interactions between two photons. If the energy at the center of mass system of the two photons is large enough, matter can be created.[1]

A photon can, within the bounds of the uncertainty principle, fluctuate into a charged fermion-antifermion pair, to either of which the other photon can couple.

From his 1952/1956 book Fads and Fallacies in the Name of Science.Martin Gardner said:Consider the following quotation: "To me truth is precious.... I should rather be right and stand alone than to run with the multitude and be wrong... . The holding of the views herein set forth has already won for me the scorn and contempt and ridicule of some of my fellowmen. I am looked upon as being odd, strange, peculiar. ... But truth is truth and though all the world reject it and turn against me, I will cling to truth still."
These sentences are from the preface of a booklet, published in 1931, by Charles Silvester de Ford, of Fairfield, Washington, in which he proves the earth is flat. Sooner or later, almost every pseudo-scientist expresses similar sentiments.
Farsight, if you can derive the electron mass then I think people would sit up and take notice a bit more. Please, go ahead. I trust you won't try to use Worsley numerology.The upshot is that the standard model doesn't offer any explanation of how pair production works, and it doesn't tell you what the electron is. Instead it cops out with "the electron is an excitation of the electron field" along with "the electron is a fundamental particle". This is like a hole you can drive a coach and horses through. Fill this hole and you reduce the number of free parameters by deriving electron mass, and you improve the model, and take it from there. But for some strange reason this sort of thing tends to be totally overlooked, and theoretical physicists then build on non-existent foundations and propose things like SUSY along with selectrons etc. This is futile when you don't have an electron model in the standard model. It's "fairytale physics".

I can't add much to what Andrew Worsley came up with, edd.
That's an understatement.We'll have to agree to differ on this, edd.
No, don't do that. It won't work.Replace √(ћG) with 4πn where n is a suitable value. Now set n to 1, and work out 4πn/√(c³).
This is because the formulae for them aren't dimensionally incorrect, like Worsley's are.Note that changing your definition of c to furlongs per annum doesn't actually change the Planck length, and nor does it change the speed of light, or Planck's constant, or the electron Compton wavelength.

You know from atomic orbitals that "electrons exist as standing waves". And you know that Planck length is l=√(ћG/c³). Replace √(ћG) with 4πn where n is a suitable value. Now set n to 1, and work out 4πn/√(c³). There’s a bit of a binding energy adjustment to make related to the g-factor, but there's the electron Compton wavelength.
