  1. cool, thanks elfmotat, thats a bit mathematically dense for me, but i think i understand it! really interesting actually
  2. So how do we know which fields are coupled? is it just some complex maths or is there another explanation? How many fundamental fields are there in all? For example you could say that there is a field for everything, but say i look at some supposed 'temperature field' (the temperature at each point in space-time), you could say that that's just the energies of the fundamental particles in the region, and then you are looking at a different field (spacetime itself?). so my question is do all fields root from a select few of fundamental field like the particles?
  3. How are all the fields linked? at the LHC, two particles collide, why do they change the higgs field and produce a higgs particle?
  4. i assume if you can detect the photons, they are real. so am I right in thinking the magnet will radiate 'virtual' photons until the photons need to interact with something, in which case the magnet will emit 'real photons'? or will the 'virtual' photons turn into 'real' ones? i guess the 'virtual' ones wont turn into 'real' ones as this may provide faster than light information travel. given nothing interacting with a magnet, will it never lose its magnetism? i thought it would as energy has been put into the magnet to align the particles to make them magnetic in the first place, and over time these will revert back to random alignments and thus the field will diminish, sort of like radioactive decay. if a magnet is in a universe with nothing in it (nothing for the magnet to interact with) will the magnet sustain its magnetism forever? constantly emitting 'virtual' photons? am i right in saying that light involves 'real' photons and the electromagnetic force involves 'virtual' photons? when are 'real' and 'virtual' photons used? of course i kow this is related to quantum theory so will probably be a strange and hard to describe answer. thanks
  5. what is the energy of a photon coming out of a standard everyday bar magnet? what end of the electromagnetic spectrum will it be in?
  6. whats the difference between a tensor and a vector? are they even related?
  7. apart from the fact that conciousness as we know it comes from physical matter and you have no evidence for saying a 'consiousness' is more likely to manifest itself, so i would say that anything is equally as likely
  8. if I want to work out how long it will take an astronaut to fly round the sun at two different distances from it (both relatively close so there is substantial warping of spacetime), can I use the equations from special relativity or do I have to use the ones from general?
  9. I think: As person B accelerates to nearly c, he will warp space time a ridiculous amount. This means he will exert a lot of gravitational force on his surroundings, and also he will perceive time in his surroundings moving alot faster, as well as his surroundings perceiving him moving slower. so it will seem to person B, that person C is moving alot faster than he actually is. I haven't worked it out, but I believe that person A will still see person B moving faster, as he is running STUPIDLY faster. you also have to take into account the fact that person C is on the race track with person B, so he will be in an area of space-time that is significantly warped too. Also im not sure, but i think having the mass of a person going at 0.999c will probably cause i black hole. im not an experienced physicist tho so im not sure
  10. surely the universe would not be able to function as we know it if there were no physical constants such as c, and thus we can cite the anthropic principle.
  11. why is this not in speculations? lol and just for the record, you state 'something cannot be created fro nothing' yet your theory relies on some conciousness being created because there is nothing there.
