The late announcement that neutrinos had been observed seeminglygoing faster than the speeding of lightsent shockwaves through the physics residential area . But there ’s one potential explanation that could keep Einstein ’s relativity inviolate and afford up a whole Modern cosmos .

It should be emphasize that we ’re still far from a confirmed result for these faster - than - spark neutrino . The findings from Italy ’s OPERA detector have abide up decently well to initial scrutiny , and a great deal of the more obvious remonstrance have been answered , at least for the time being . But there ’s still every chance this is some form of systematic misplay , and we wo n’t be able to hold this an actual find until the results can be retroflex elsewhere , with many other squad already beginning their own experiments . This is still a crazy result , and our first , second , and third reactionsshould all be deeply sceptical .

Still , while it should n’t yet be regard the most potential possibility , let ’s imagine for a present moment that these results stand up and it turn out the neutrinos really did go far at their goal 60 nanosecond faster than the speed of light would allow . What then ? While it might seem that such a breakthrough would invalidate Albert Einstein ’s theory of special relativity – which take it as a give that the speed of light is the right-down demarcation – there may be a way to conciliate the theory with the results .
The mind is that the speed of light does remain the libertine possible speed in the three spatial dimensions we ’re intimate with – but that the neutrinos are n’t just traveling in those dimension . Instead , they could take a shortcut through a theoretical quaternary spatial property , which would provide a shorter length between two points than would be possible in the normal three attribute . The neutrino still are n’t exceeding the speed of light in this scenario . And yes , that is fundamentally the corpuscle aperient tantamount of doing the Kessel Run in twelve parsec .
Anyway , the larger idea here is that the three spacial dimensions and one temporal property we ’re familiar with are what make up a four - dimensional tissue layer , known as the brane . However , this brane “ plasterer’s float ” in a expectant reality sleep with as the mass . While in the ordinary course of action of things it would be insufferable to leave the universe – to leave the brane – at incredibly mellow energies it might be potential for particles to temporarily break free and zip through the bulk .
This may be all getting a bit metaphysical , but a lot of these approximation are crucial to string possibility , which takes superfluous concealed proportion as one of its primal feature of speech . Until now , string possibility has remained an elegant theory that is completely beyond the bounce of experiment . If – and , again , this is one jumbo if – the OPERA results book up , that could present the first tangible grounds for string theory .
Basically , it ’s possible for Einstein to still be right and the hurrying of sparkle to remain inviolate even if this termination turns out to be a actual discovery – his hypothesis might just turn up to be reasonably uncompleted . And , if that ’s the face , then we ’re on the verge of some seriously exotic new region of physics . It ’s a little too early for that much optimism … but it ’s still an extremely challenging persuasion .
