Scientists may be on brink of discovering fifth force of nature

Semantics is generally not the most interesting topic, but since the actual science behind the title claim is well-discussed elsewhere...

We already have strong evidence of a fifth force, the Higgs force, by most accountings (assuming you enumerate the other low-energy forces as gravity, electromagnetism, and the strong and weak forces; or, if you look at the higher-energy gravity, SU(3), SU(2), and U(1); either way).

IF the g-2 experiments point to unknown particles (which seems unlikely), that could (and also could not) point to a sixth force.

AFAIK the effects due to the Higgs are not normally considered a separate force; to the extent they are a "force" at all, they are considered part of the electroweak interaction (the Higgs mechanism for giving mass to other particles, for example, is an effect of electroweak symmetry breaking).

As I said, semantics.

But Higgs bosons do mediate momentum transfer, which is about as good a definition of a force as I can come up with.

See e.g. http://resonaances.blogspot.com/2016/01/higgs-force-awakens....

> Higgs bosons do mediate momentum transfer

The blog post you reference appears to say that this is true in theory (though impossible to detect experimentally as the effect is so tiny), but it would be nice to see an actual paper describing the specifics. For example, what do the Feynman diagrams for this "Higgs force" interaction look like?

See e.g. https://arxiv.org/abs/1601.05087; the area around eq 3 discusses the attractive force due to Higgs boson exchange, and the paper as a whole discusses testability.

The leading theory being defended here is tha bigger and bigger particule accelerators are a good investment for society.

Not blaming the guardian, but the PR of physicists.

tldr; the fifth force of nature is love

You beat me to it. I was just gonna quote the fifth element.

underrated movie. the world needs more weird sci-fi pairing Chris Tucker with Jean-Paul Gaultier and Milla Jovovich.

and not to sell Bruce Willis short, but Gary Oldman stole the show with a dead-on Elon Musk impression which he somehow performed before Musk got famous.

(so maybe Musk is the one doing a Jean-Baptiste Emanuel Zorg impression.)

Underrated by who?

I don't think I've ever heard somebody "Eh, it was alright".

There is now even more underrated, than The Fifth Element but not less weird and good sci-fi [1]

Whatever happened to blaming results on cosmic rays?

My bet is on something created by matter anti matter annihilation and very hard to measure. Like you annihilate two parucles a c and gravity wobble for a splotsecond..
