Dark matter discovered

[mattheman]

Physicists have detected a particle of dark matter for the first time in human history, a number of U.S laboratories announced today.

Should the findings be confirmed it will have an Earth-shattering effect on our understanding of how galaxies form.

do you think messing around with this could cause the big bang 2?

 

[mattheman]

a question..

why would it cause big bang 2?

dark matter isn't something destructive like anti matter and hasn't got much to do with the big bang theories. Other than there is more gravitation in the galaxy other than there should be.

Oh and source of info. Seeing as it is not visible how did they find it?

It had an influence towards our cosmic evolution.

 

[mattheman]

You are assuming there has only been 1 so far . . . .

No.

The Big Bang - Nothing exploded and became something.

so you suggesting there have been muilt big bangs expansion and then contraction etc...?

 

[mattheman]

yes due to gravitation, so the debris from the big bang wasn't spread out all over the shop, but clumped together. As far as I am aware it had nothing to do with the big bang or what caused it. so how would it now suddenly cause a 2nd big bang.

what mechanism or even theory links dark matter to the creation of a big bang.

And what proof do you have?

 

[mattheman]

No, but it is completely possible. I am just making a point. They reackon it could have happened countless times. I am just saying do not discount it.

but it doesnt take into the account the speed of expansion is speeding up, and at what point does it stop.
Think about this in trllions of years the distances between galaxies would be greater than now, the energy required to travel in a line would be huge, so out comes the idea of folding space and time.

 

[mattheman]

Current big bang theories. Again why would it cause a big bang why did you think it could cause a big bang? if current theorys are correct 90% of the universes mass is dark matter anyway.

why are you asking for proof, why aren't you saying why you think it is even possible or why you think that.

To get you used to the idea that sometimes you can't prove it yet, same as many other topics around Conspiracy theory.

 

[mattheman]

No I don't think it will cause a big bang.

ok put it this way dark matter is what hold the galaxies together, via gravitational galactic rotation if we mess with this who says it can't alter its formation to a increase push or pull effect.
For example the theories of muilt big bangs expansion then a sudden contraction then an exposion and expansion.

 

[mattheman]

what, do you actually think about what you are saying. how is a few particles going to change gravitational pull, when there are more dark matter particles theorised than I can even comprehended yet along put in a written form. The gravitational force is tiny and you need a huge amount of mass. energy can not be created or destroyed. there is always a changing amount of matter. It's also DETECTED not created. Even

a chain reaction, sometimes comes from the smallest change, if we interfer with this change who knows what could happen.

 

[mattheman]

If I step out of the office I could get hit by a bus, should I leave or simply stay here and not mess with chance?

The thing is, if they "mess" with it we could learn so much about our universe, if in doing so we destroy the universe....whose going to know?

ok lets say hitlers non cancerous polyp did turn cancerous and died would we still see a 2 world war.

 

[mattheman]

Are you suggesting dark matter could kill Hitler and change history?

what iam saying its a direct alteration can lead to other effects sometimes unwanted.

 

[mattheman]

Whole differant ball game.



That is true for every act of human kind for the entirity of history, the problem being the only way around it is to never do anything ever.

not really the theory is the same the consequence differs.

 

[mattheman]

You quote something without giving a source and then say something without justifying it in any way and expect a decent discussion? Was their actually some thought process involved in wondering whether detecting dark matter could cause a big bang, or did you just get excited and think 'i've heard of dark matter in cosmology and i've heard of the big bang, they must be intrinsically related!'

Are you also one of the people that thinks CERN might destroy the earth while ignoring the fact that cosmic rays cause higher energy interactions in the atmosphere than CERN can ever create?



Right back at you.



Nobody knows why the expansion of the universe is accelerating, but if you are genuinely interested go and read about the cosmological constant.



What?

For anyone still looking for a source.

I've studied astronomy and cosmology and never heard of a link between dark matter and time before, guess you learn something new every day.

Some dark matter particles could explain why ordinary matter is not radioactive, while others may help scientists understand why time – so far as we know – always runs forward.

which is pretty interesting idea about time and space.

 

[mattheman]

and why ignore my post. what do you think we can do to this dark matter. we shine a bit of radiation at it. It's already gone through every source of radiation and at every level and hasn't caused a chain reaction to form a big bang. we shine a bit of light at it, again it's already experienced that with no big bang. we give it some electrons. guess what the universe has done that already.

Dark matter stretches throughout space where it attracts ordinary matter that coalesces into galaxies of billions of stars and planets. It forms a kind of cosmic skeleton that gives the universe its structure.

Think if we played around with it we altered a certain part of it, the skeleton structure changes form setting of a chain reaction causing a pull event.

 

[mattheman]

what has human history got to do with physics.

a lot it has altered our direction in many ways and to suggest that both dont influence each other is just stupid.

 

[mattheman]

I hereby invoke my credentials as a third year theoretical physics student and declare matttheman's posts meaningless and uninformed drivel. Nothing to see here.

matttheman: how on Earth is observing dark matter going to cause a second big bang? Really? Try engaging your brain; it's a powerful tool.

Well dark matter only partially negates that effect. Based on the current numbers the universe is actually blowing itself apart. And it will continue to blow itself apart until eventually even something like the earth, or us, gets ripped apart by the expansion of the universe. And you end up with an entire universe containing nothing but one particle in it. So the universe will become a very lonely place. It really is blowing itself apart in a very ridiculous way. But, you're right. There's an awful lot of mass slowing it down and pulling against it. And in fact about 10 times more mass than you would guess from just looking at all the stars and galaxies and biologists in the world. And that matter, we know it's matter but it doesn't shine and so we call it dark matter

think you have spelling mistake, just pointing it out.

 

[mattheman]

they've found some signals that might be something, or background noise - thats a non event if ever i saw one.

and what qualifies you, too say this? apart from watching sg1 etc...
