Guest Dark Sotonic Mills Posted 23 September, 2011 Share Posted 23 September, 2011 (with apologies to Saint in Paradise) It seems that some neutrinos generated at CERN haven't listened to Einstein and have had the audacity to travel faster than light.

There are some alternative theories about if dark matter doesn't exist and thus cannot explain some astronomical phenomena. This would mean modified gravity theories are probably most likely but that would mean that Newtonian and Einsteinian physics isn't really sufficient.Not much sign of the old Higg's Boson as yet either.

pap Posted 24 September, 2011 Share Posted 24 September, 2011 While I cannot claim to have an in-depth knowledge of Einstein's work, the cool thing about this discovery is that the limitation his theories placed on us is suddenly gone. We probably won't see it, but humanity will need to leave the Earth at some point. If we had been limited to the speed of light, even a trip to our closest neighboring star system would have been an 8 year round trip. From my limited scientific knowledge, I understand that Einstein's reason for suggesting that nothing can go past the speed of light is that because photons have no mass. A neutrino doesn't weigh very much, but has mass, and scientists reckon they've seen neutrinos move faster than photons. Someone please correct me if I'm wrong. Last time I did any physics was in 1991 As to Einstein spinning in his grave? Possibly. But given that science is evidence-based, I'm sure he'd have a couple of alternate theories if he had seen the stuff going on at CERN. Link to comment Share on other sites More sharing options...

Mind you there are a couple of "I told you so's" and "knew it all alongs". A customer of mine was a quantum theorist, I saw him maybe twice a year but we became very friendly, in fact I have a couple of copies of his books on the subject given to me by his widow after he died. I asked him once about how his work squared with religion and the paranormal, he said "its conceivable. And if its conceivable, it has happened or is happening." I got a bit lost when he explained this idea, but he reckoned that absolutely anything that had the remotest chance of existing does exist, and that included all forms of mysticism and the paranormal. So I suppose that if its possible for anything to exceed the speed of light there must be things doing just that. Above my head, I'm afraid.

Same principal in finding it though, if you bang about about you'll eventually hit the sack with the cat in it and it will make a noise,trouble is as dark matter in theory emits no electromagnetic radiation or any light you have to find the right stick to hit it with.

The timing is from point a to point b, not "how fast it appears to be going when it travels past me". But surely the way the timing is done is that the two ends of the route are using a common reference time source and the elapsed flight time is taken from the observed departure time at one end and the observed arrival time at the other. Therefore, as time is relatively slower at the Italian end, ( as it is travelling faster with the rotation of the Earth ) the recorded time taken with reference to the common time source will be earlier than expected, hence the travel time is recorded as less than it should be, and the neutrinos appear to be going faster. Personally I reckon it's option (3) from my list anyway. Link to comment Share on other sites More sharing options...

Some experiments at Cern agree with the predictions of relativity to better than one part in a trillion – that is like measuring the distance across the Atlantic Ocean to better than the width of a human hair – but only when relativity is taken into account.

badgerx16 Posted 20 October, 2011 Share Posted 20 October, 2011 Watched a program on BBC2 last night about this experiment and how the observed results might be explained, inclduing the great amount of effort put into eliminating variable factors and areas of potential error - including the impact of tectonic movements on the distance between the emitter and receiver. Towards the end they went all 'theoretical maths' to show how that field 'allows' things to travel faster than light, and some talking head reckoned that under String Theory it is possible that the neutrinos transiently switched into being tachyons, which by definition MUST travel faster than light, and then reverted before being detected.

I'm a bit out of date on all that stuff but I'd not heard that the actual existence of tachyons is proven,unless this experiment proves it of course. One theory is that tachyons appear to travel faster than light because they're actually travelling backwards in time... If that's what's happened here, with neutrinos changing to tachyons and then back again, it'd still be huge in a physics sense, as it'd be the first time we'd observed something changing the direction it travels through time. That also opens up a huge can of worms on how it interacts with entropy, cause and effect, paradox.... Link to comment Share on other sites More sharing options...

Correct, the point was being made that theoretical mathematics has on several occasions suggested the existence of particles, including neutrinos and quarks, that have subsequently been discovered, at that possibly this result is the first step on the path to proving String Theory. I suspect, however, that they are desperately searching for a theory that fits the perceived observation, and that it will all eventually be shown to be a mistake in a formula.

shurlock Posted 18 November, 2011 Share Posted 18 November, 2011 (edited) Media reporting of science truly is awful. I know they need stories, but it doesn't help general understanding. It's still hugely likely it's a testing error. Initial retests getting the same results doesn't mean much, there'll be hundreds of retests and checks before truly believing they've travelled faster than light. I'd be stunned if it turns out to be true. Still countless technical errors it could be, given what tiny margins of time we're talking about. At least it gets science in the news though, and highlights the right way to do things, i.e. exploratory experiment which no agenda in what you 'want' to find, just trying to further knowledge, then when results come in, they're thoroughly tested repeatedly until clear information is apparent. In many ways this strikes me as better than 'ancient book is right, stopping listening now'.
