Ok perhaps CTG can help with this one, I think I'm right in saying that the LHC collisions are at 99.9999991% of c. No doubt the new one will get even closer to c but what else could come out of that that we are not already getting with the LHC?

Note I am in no way against this contruction I am all in favour of the spend just need bit more info.

Wow are you really sharing that the word isn't flat.

These partticle Physicist have a lot to explain.

Quantum machanics made simple... 2b or not 2b.

[ToraToraTora]

I think the problem is that they have to say what it'll do in terms that the general public can understand so they say things like "Unravelling the secrets of the big bang" - that really has no meaning to anyone in the science world it's more for public consumption. Hymie has bought into that and expects tha LHC to spit out the answer to the ultimate question of life the universe and everything.

[Hymie]

I wonder what the difference is between ‘oversold’ and ‘false claims’ – let’s hope that scientists are not overselling the FCC, as was done with the LHC.

 

If you listen to what Michio Kaku said in that video, he announced what would be discovered as the LHC finally became operational.

[Arksided]

I'll stick with Isaac Asimov... of my understanding.. not Prof Hawkings... with respect.

// I think the problem is that they have to say what it'll do in terms that the general public can understand ... //

Indeed - and this applies to a lot of specialist research. At times that means that actually sound ideas can get lost, because the point sometimes isn't as clear without the technical language. It's well to remember that, whenever anyone finds themselves having to express often years of personal and collective research efforts into just a few words, something is lost.

As to Michio Kaku, he was wrong, and he shouldn't have said what he did. A lot of physicists at the time will have thought as much. But he didn't work at the LHC himself, and shouldn't be taken to speak for the field - because, again, science isn't done in tv interviews.

12:34: who is Professor Hawkings?

[ClareTG0ld]

Also, Arksided, I'm not sure I understand your point.

[Old_Geezer]

That would be Stephen, T³.

"In 1974, Hawking was inducted into the Royal Society, a worldwide fellowship of scientists. Five years later, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world (the second holder was Sir Isaac Newton, also a member of the Royal Society)."

[ClareTG0ld]

I suppose TTT was making a point that it's Hawking, not Hawkings, but it's (unfortunately) a common misspelling of the name.

OG. How do you produce the cubed symbol?

[Peter Pedant]

The first one was isaac barrow who translated to a professor of divinity (there are forty, currently two filled)  - and Barrow really did posit - I shouldnt be Lucasian Professor, Mr Newton should.

who else said that - well - Arthur Keith -  Dart was right and that I was wrong.” This simple phrase may seem like a small gesture, unimportant in the grand scheme of things. (piltdown. Dart was right about australopithecus) (*)

and I really cannot think of any other. ( DOI my father was one of Dart's students)

(*) The goldfish will bloop - australopith- hoo- cus ?

[Peter Pedant]

Clare - thanks for your input

Should the FCC ever be built, I won’t be around by then to see the results – but one result I can guarantee from the FCC, is that scientists will say they need a larger collider with higher energy collisions to further understand particle physics (where have I heard that before?), and keep the gravy train running.

 

I recall there was a concern with the LHC that the high energy collisions (compacting materials) might result in a micro-black hole, which would rapidly/instantaneously grow to consume the world.

This of course never happened, but with much higher collision energies (with more material, more tightly packed), no one seems to have resurrected this scare story.

[ClareTG0ld]

// ... but one result I can guarantee from the FCC, is that scientists will say they need a larger collider with higher energy collisions to further understand particle physics ... //

Setting aside the framing, this isn't wrong exactly. Since -- we can safely assume -- particle physics as a field will never run out of things to discover and explore, then, yes, an even larger machine in future would be needed if you want to explore further boundaries. The coherent physics reason for this could be expressed in terms of orders of magnitude. Prior to the LHC, we were operating at a scale of about 1 (in some arbitrary units). The LHC has taken that scale to 10 times larger. The FCC could reach 100 on this scale. But we are already, at a minimum, expecting new physics at around 100 million million on the scale. So there would be a huge amount of ground still to cover.

In practice, to get anywhere close to that sort of figure would need a particle accelerator with a circumference comparable to the solar system or even larger. But since the answer to "is there more to discover" is always yes, then, yes, something after the FCC will also be pitched for. Whether it's a larger collider, or something different altogether, who can say? But this is obviously not intended to be the last experiment. For theory reasons, though, not just some cynical financial gain.

Until now, of course... but it was never a serious concern to begin with, and that hasn't changed now, so it hasn't been resurrected because it's completely unfounded. 

[Hymie]

I leave you with what I hope to be my last posting on this thread (from Private Eye, many years ago), and that is that some publication had referred to the LHC as ‘The Large Hardon Collider’.

Atheist.

The easiest way on my mobile is to long press the 3 key and a menu comes up for which 3 related symbol I want.  The first option is ³.

On a PC, it may need to websearch, highlight, and copy & paste. It's been a long time since I needed a ³ at the PC. (Although you could check Windows "char" programme as it should offer all options.)
