quisquose Posted September 23, 2011 Share Posted September 23, 2011 If neutrinos travel even slightly faster than c then over the vast distances of space this would have added up to considerable differences in detection when studying a Supernova surely?

Jeffrey Shaw Posted September 23, 2011 Share Posted September 23, 2011 Fermilab confirmed excitedly that they had made a similar discovery, equally crazy, in 2008. No, it's the same discovery (but it travelled back three years). Proof! Link to comment Share on other sites More sharing options...
PeteMorris Posted September 23, 2011 Share Posted September 23, 2011 Didn't Einstein predict that if the speed of light were to be reached, then time would effectively move backwards? Assuming this premise (as there isn't an alternative yet), then technically this discovery hasn't happened yet! The eternal paradox!...:D:D:D Link to comment Share on other sites More sharing options...
shanes teeth Posted September 23, 2011 Share Posted September 23, 2011 Sub atomic particles disobeying our rules of physics eh! Damn those anarchic sub atomic particles,coming over here,disobeying our rules.Send them back where they came from says I. Link to comment Share on other sites More sharing options...
John X Posted September 23, 2011 Share Posted September 23, 2011 The scientists, being unable to find any explanation for their findings, have published them in the hope that someone else will find one. Does anyone remember 'Cold fusion'? John X Link to comment Share on other sites More sharing options...

Phanerothyme Posted September 23, 2011 Author Share Posted September 23, 2011 Jim Al-Khalili will eat his boxer shorts on live TV if it turns out to be the case that these neutrinos are exceeding the speed of light. Link to comment Share on other sites More sharing options...
ampersand Posted September 23, 2011 Share Posted September 23, 2011 Could anyone explain to a simpleton who managed a grade 5 cse in physics (and still doesn't know how), in words he might have a chance of understanding, how the speed of light is determined (in other words, how do we know how fast it goes?) I read somewhere (on the BBC I think) that it was something to do with the theory of relativity - if so, isn't a theory, by it's very definition, unproven?

Phanerothyme Posted September 23, 2011 Author Share Posted September 23, 2011 You can easily measure the speed of light yourself, it's not so fast as to be unmeasureable. With a couple of mirrors and a cheap laser, you can DIY like this: http://upload.wikimedia.org/wikipedia/commons/4/46/Speed_of_light_%28foucault%29.PNG Link to comment Share on other sites More sharing options...
John X Posted September 23, 2011 Share Posted September 23, 2011 Could anyone explain ..... ..... how the speed of light is determined (in other words, how do we know how fast it goes?) A good way is to bounce a laser off the moon and measure how long it takes to return. (1/2 a million miles) John X Link to comment Share on other sites More sharing options...
