Faster than the speed of light
 

Could Einstein's theory of relativity be about to be up ended?

Doubt it.

They could probably get round it........like the universe inflating faster than the speed of light. Tricky though as a lot of physics is based on it :)

Bet I could beat it in the twistys.

if your moveing at the speed of light (or faster) what happens when you turn your lights on ??

Depends on where you are observing the light.........driving the car it would leap away from you at the speed of light. Sat at the roadside it would not leave the headlights.

Shaun

.........at least that's how I remember a level physics 1978 LOL

I would love to be left alone with the LHR, imagine, instead of Neutrinos and Quarks and **** of you could put stuff like Hamsters in it.

Are they Porsche Neutrinos?

errr, how do they know the distance between the points to measure vs the speed of light so accurately?

By sending a laser and working out the distance from the time it takes to reach the other end.... ahhh... lmao.

It's all relative :D

:lol1: They'd be the fastest hamsters going round the biggest hamster wheel!!

you serious - over 732 km?

No I am joking they send a hamster with a bit of string ..

v funny. but really, how could they measure the distance along the path that these particles take accurately enough to claim they're faster than the speed of light?!

Laser - like they said above

They use atomic timing devices that are super accurate.

This is crazy news.

but the neutrinos are travelling through the earth's crust (given the earth's curve is a factor over that distance).

I think you're confusing lasers (which lose their accuracy in earth's atmosphere at pretty small distances, i.e. 20km or so, never mind the inaccuracies you get with the measuring / relay instruments along the way, the impact of gravity, the fact that the neutrinos wouldn't take the same line etc etc) with atomic clocks - which, contrary to popular belief, run slightly differently at different altitudes - and still don't help you measure the distance between two points.

???

Being serious for a seconds, you are right they don't have a physical connection. Its a point and shoot situation. They detect only a few hundreds or a few thousands of particles at the other end. Its the biggest, educated guess experiment ever carried out imho. This problem will explained, imho.

I know sod all about physics (clearly :) ) - but in my head neutrinos don't hit things along the way, which makes them so hard to detect, whereas photons bounce off things which is why the speed of light is meaningless unless measured in a vacuum. You could use a form of light which is non-visible (e.g. radio waves of some form?) but they'd get slowed down passing through the rock vs the neutrinos, even if they took exactly the same path, which is doubtful.

i.e. I'm surprised everyone's taking as gospel that a key part of this equation is correct (distance), especially given they're saying the neutrinos are only about 20m ahead over the distance involved - presumably that's why the CERN scientists are asking for external review, rather than claiming it's true.

I'll stop now as it's too late to ponder this when the financial world's going to hell around us.

Gordo...Neutrinos are not affected by gravity... :)

I know it was written a long time ago but there is a book called the God Particle which is a pretty good read......Ok I have a PhD LOL

I didn't say they are - but light is :)

Check out the big brain on Brad, He's a smart mutha fcuka thats right!! :lol1:

The gravity train.....

i do actually know the answer to this. towards the speed of light everything slows down time wise this is apparently natures way of protecting the speed of light as the maximum speed anything can go so anything leaving or produced by the object travelling near to or at the speed of light will be slowed by the effects of time being slowed.

In the course of doing the experiments, the researchers noticed that the particles showed up a few billionths of a second sooner than light would over the same distance

Not even a car length quicker :cuckoo:

TX.

We know the speed of light so can calc how long it takes to travel that far ... the particles simply get there faster.

TX.

the higgs, all that **** blows my mind,

the 2 slit experiment is the main one that gets me though, as it works with photons, electrons and complete atoms. and how basically everything we know only exists if it is being observed:freak3::wonder:

Heisenberg is all I can say!!!!
