It Seems That Neutrinos Do Not Exceed Light Speed, After All...

[A.J]

I call it maturing from one's first childhood into one's second

Anyway aren't there exotic particles which do exceed the speed of light?

Yes there is, well, at least theoretical particles called Tachyons.....They are in essence, mass less (or have imaginary mass) particles which gain velocity as they lose energy, ...It's theorized that the Higgs Boson originates as a tachyon and through the breaking of symmetry becomes a sub-luminal particle which has mass

By knowing when it left, and when it arrived!

But, if it were exceeding light-speed, wouldn't it arrive before it had left. Unless quantum-entanglement were somehow be involved?

They're the green ones, on Star Trek...

No...though I had to really think about it! I'm a geographer not a physicist lol! The transportation time would still be relative to light speed so therefore it would still arrive after it left (I think?!) lol.

Totally

But, would it arrive in the past though?

I have a lot of time for people interested and competent in physics and the study of. One of my closest friends has a PhD in the subject so I have a lot of interesting conversations with him! I'm certainly humbled in my specialisation in human Geog when he demonstrates some of his knowledge in the field of physics!

Interested and not so?

I think there's a few other mass-less theoretical particles but Tachyons are allowed within SR and do not present a violation?

Why?

yep Tachyons don't violate SR because they are always at superluminal velocities, they never cross the light barrier to subluminal velocities...yet as I posted it has been theorized that the Higgs starts as a tachyon, how can that be?....My understanding is that higgs only ever existed in nature during the superluminal inflationary epoch (from the Planck time to 10^-30 seconds after the big bang, when symmetry was broken)....or have I got that right?...damn it, need to get my Brian Greene books out and swat up...lol

Why?

I don't know why, ergo my question mark...But isn't entanglement the only way information can be transmitted instantaneously, across distance - if it can at all? But, as quantum theory is so full of paradoxes anyway, I guess the notion of a particle arriving at a location ahead of its associated information might not be all that strange, of itself??? But it could make velocity-measurements difficult/complicated: like, how can you record its time of arrival if the knowledge of that arrival hasn't arrived yet?

My brain hurts!

But, would it arrive in the past though?

Now that's the question!

Me too!

[A.J]

based on the above posts, I have calculated that the England football team have super-luminal properties....You already know when they're going to get beaten before they've even played a game...lol

[Methuselah]

Has a tachyon ever been properly identified yet, or are such things still only hypothetical?

Where's the bloody vodka!

That's better!

No Pete, purely hypothetical

No Pete, purely hypothetical

Thank God for that!

[A.J]

Thank God for that!

of course, I could aid confusion and state that they've already been discovered........20 years from now

[Cheshire Freeze]

I don't know the exact thesis, but it involves a lot of research centred around black holes. Here is one of his pieces of collaborative work http://arxiv.org/abs/1106.2135

Not even the world's top scientists could understand the mechanics of our storm shields

[davehsug]

What about those particle thingies that can exist in 2 different places at the same time? They must be fiddling the clock somehow unless they've got Derren Brown as a publicist?

Discussion on Higgs Boson on 5 live at the mo. If they can make it simple enough for Tony Livesey to understand, some of us might have a chance!

It might send us off to sleep if nothing else

In my case, it did just that!

[Coast]

Sorry Coast, but that article relates to the search for the Higgs itself, not to the search for/speculation of faster-than-light neutrinos

See, just goes to show, one shouldn't stick ones nose in where you know nothing about the subject!!!!

So why are you posting on a weather forum Robin?....Ouch!!!

I'm utterly jesting of course matey, just couldn't resist...You left the door open and I just barged on in!

you'd think I'd close and lock it behind me wouldn't you?

[A.J]

Don't worry Robin, AJ told me he gets his info from Wikipedia anyway

Microsoft Encarta 1997 Edition & The Children's Illustrated Book On Space 1974 Edition actually...get your facts right

[A.J]

Blimey, that's radical, I'm still on ABC my first quantum mechanics

aren't they blokes that fix very small cars?
