Why should I waste my time with you? Anything outside of a textbook is automatically wrong in your narrow mind.
You have a go at me for supposedly not backing up my claims but when you make a claim you don't need to back it up?
And you're making hyperbola. The fact textbooks are written on material which have a great deal of experimental evidence and are, demonstrably, approximations to the behaviour of Nature doesn't mean that saying "I think that this is worth knowing" is equivalent to "This
and only this is worth knowing". I know Newtonian gravity is wrong, but I none-the-less think its important to know for anyone doing gravitational work. I know Newtonian mechanics is wrong but I think its important for anyone to know before they do relativity. I know Maxwell's electromagnetism is only an approximation to the true behaviour of electromagnetic phenomena but its essential reading for anyone doing work in that area. Science only advances by learning about previous work, either to build on it or to avoid repeating its mistakes.
If you have an experiment which demonstrates E=pc is wrong for a photon then it would be an
enormous thing and the investigation of such an effect would greatly advance our understanding of Nature. I've sat through dozens of seminars on people explaining how they test their ideas using experiments to parts per thousand or million or
billion. Or how their idea can be tested. The people who think science is about close mindedness and never testing models are just plain fucking ignorant of science.
If $$E \neq pc$$ then a model which accounts for this needs to also have a reason why E=pc is true
for most experiments, because every experiment done thus far has seen E=pc. That's an unavoidable fact and any model which says $$E \neq pc$$ is always the case is going to be wrong. Relativity explains why people arrive at the notion that Nature has Galilean symmetry and not Lorentz symmetry, because when you're moving very slowly Lorentz transforms look like Galilean ones. Quantum mechanics explains why large numbers of particles seem to behave in a predictably way, decoherence. The new idea explains why the old one
seemed to work but on careful inspection actually doesn't.
You whine about how quantum mechanics doesn't have applications while sitting infront of such an application, in a room whose power comes from (partly) nuclear power stations. You whine about things you don't understand and you have the hypocrisy to criticise me for not backing up my claims when 1. you didn't bother to investigate yourself and 2. you don't back up yours.
And another example of your hypocrisy is saying I should go be vitriolic to q_w when you call me 'pinhead'. Wow, how mature of you. Do you and I learn your insults from the same place? Every time I type a coherent reply like this and you respond with 'pin head' or 'Blah blah blah' you show you're all talk and you can't even follow your own advice.
