I'm fascinated by stuff like this, and it's being reported today that the biggest scientific break through since Einstein's, Theory of Relativity has just been announced!

Everybody is being very cautious right now and the results of the experiment are being poured over and need to be repeated and confirmed by others but they seem to think they have discovered an unknown 'fifth' force of nature!

Amazing if they actually have!

Shock result in particle experiment could spark physics revolution

Same here Norpig, I’m nowhere near clever enough to even begin to understand all that!! 😞

Exciting news. However, I'm still struggling to open my jar of blackcurrant jam, which seems to have an alien sealing device, or lid, if you will, of unknown origin.
These scientists need to get their fingers out.
Sod it, I'll have a biscuit. 
'Pull tab here'. Hmm.

I've watched 'Big Bang Theory' so I get it.

I'm too clever for you lot.

It's not rocket science.

Basically, the scientists may have got their understanding of a subatomic particle wrong - or they may not have.

It may be an important subatomic particle or it may not be from a human perspective. Most likely not as we can't make them or control them - to do something useful like accelerate atomic decay which could be used as anti-nuclear bomb weapons or decommissioning old nuclear plants quickly and safely.

Either way, they'll spend years debating it.

Come on mate Smile

For 50 years they thought a little thing was a certain size, now they're not sure so they're wondering if something else they don't know about can cause it to get bigger.

That do? Smile

Quantum physics is exceedingly complicated, I can't claim to understand it in the least but here's a simplified understanding of what I believe I know.

Before the Big Bang it is thought there was only 'energy' and thus EVERYTHING even us have derived from energy.

The big thing that has evolved following the big bang is that of 'matter' (the stuff that things are made of) and how/why whatever makes up what 'energy' is, came together to make 'matter'.  We now understand that to be the Higgs Bosun.

A 'bosun' is according to quantum physics a 'particle' of an atom.

By smashing two atoms together and shattering them apart, scientists have been looking to see what they are composed of and how they 'work' and what functions they serve within atoms.

All these elements within atoms are 'held' together in some way or other and atoms interreact with each other and how they do is known as 'forces' (strength or energy exerted or brought to bear).

Up to now we only knew there were four forces - gravity, electromagnetism (of which electricity and magnetism are parts of the same force and combine together with each other to attract 'particles' together - one of the results creates 'radiation' and part of the spectrum we can see of radiation is 'light' (as in sunlight)).

The other two forces apply specifically to how atoms work, the strong force stops atoms all joining apart, and thus stops one massive blob of all the atoms together. This prevention of keeping atoms apart from each other is known as the 'strong' force.
However if you only have one type of atom - the simplest of which is the Hydrogen atom - then all you will ever have is Hydrogen!

If however you have enormous pressure you can squeeze two hydrogen atoms together, which turns hydrogen into 'Helium' and to stop those two hydrogen atoms simply popping apart when that pressure is removed is a force named the 'weak force'.

Therefore all the elements we know about are created by squeezing different elements together (and them staying together thereafter) and thus give us our 94 elements naturally occurring elements in nature.

So in simple terms, out of nothing but energy the big bang occurred which led to a 'soup' of particles that over time cooled formed matter. 'Gravity' started to pull things together and create the first stars made entirely from Hydrogen, which under their own weight created and caused immense heat that triggered radiation and 'electromagnetism' or the first light in the universe.

The different elements kept away from all joining together by means of the 'strong' force but those that got crushed together in the centre of stars formed new elements, and stayed as new elements and didn't pop apart from each other once the force was taken away by means of the weak force.

So hopefully you can see from my explanation that each of the four known forces are hugely important to how we and everything else was created in the universe - and how everything works.

However, all our knowledge of these four forces doesn't explain all that we see and know about - we know from scientific research and understanding that there are gaps (big ones at that) to what we know - we know that there should be more matter in the universe than what we can see - so we call the 'missing' matter - dark matter, similarly we know there is more 'energy' than we know about too, and we call this missing energy - dark energy.

There must be something else we don't know about - a 'fifth' force or maybe even more to explain this dark energy and matter - we don't know how it works or what implications it might mean to us, what doors it could open to us...?

The announcement above is saying they might have now found this 'fifth' force.

It's very early days yet and others need to repeat the experiment and get the same results to be sure that there has been no mistakes and we can now prove the existence of the fifth force.

The experiment is basically showing that more matter is attached to one of the particles of an atom than there should be under known forces - if so there must be a force we don't know about allowing this to happen.

Hope this helps people understand a little bit more as to what this is all about?

Nah, I don't believe anyone is thick, we all have our own strengths and weaknesses.

Stuff like this interests me, so I've tried to understand it a bit more - that's the only difference.

I'm no brighter or thicker than anyone else and I'm sure you are just the same as me.

I'm sure you have interests that I wouldn't know much if anything about.

I used to be an avid reader of New Scientist magazine, and my younger, nerdy self was all over this sort of stuff, but as the years passed I found myself venturing into other spheres.
Still take an interest, but I'm not across all the latest info.
No one should feel stupid when looking at this sort of stuff. The people on the cutting edge of science are living in a rarified atmosphere, almost unbreathable to most of us. 
Thank God for the great tv communicators, who have the ability to break it all down for us.
Anyone remember Carl Sagan, and his brilliant series, Cosmos? 
Popular science at its best.

If it is what interests you then so what?

When my daughter was at school and moving on towards college and then university I told her to pick the subjects that she was interested in and not the ones she might have felt would please me for her to do.

To my mind if you have an interest in something it encourages you to learn more about it, it is more an enjoyment to you and not a chore and which you will ultimately give up on because you don't enjoy doing it.

I wouldn't have tried to learn about stuff like quantum physics if I didn't find it interesting and enjoyable and you would not have anything like the same interest and knowledge in music as you do if music was 'forced' on you rather than what you wanted to involve yourself in.

Fair play to you delving into stuff you like - that's just the same as what I do.

Doesn't mean that one of us it clever than the other, it simply means we have separate interests where we might be more knowledgeable about it than those who don't share that interest.
