		<description>Can we take from this that galaxies will become further apart from each other, but that individual galaxies themselves will remain unchanged, i.e. stars will not drift apart eventually dissipating the milky way into nothing? I&#039;m not sure if i&#039;ve phrased that well enough- will galaxies be undamaged, but isolated?</description>

		<description>If the Universe is expanding at a faster rate,
maybe at 13.7 billion years old the universe hasn&#039;t started to slow down yet. And will start slowing sometime in the future..
  Or maybe the Universe has already stopped expanding and is now speeding up returning to the &#039;beginning&#039;&#039; of time.</description>

		<description>more jargen:

all galaxies flying away from each other. except andromida &amp; the milkey way (and all other colliding galaxies) Dark matter/energy? Lets call it what it is-cosmological constant (unkown). Must be their for theory to be correct, its not possible we&#039;ve error&#039;ed</description>

		<description>The only reason the Standard Model does not &#039;fail&#039; is that cosmologists keep adding patches when a new bit of information comes along that contradicts it.

When a patch can not be added, the data is swept under the carpet.  Like Halton Arp&#039;s work.

The Standard Model is also self contradictory.  Like....  Nothing can go faster than the speed of light... unless of course we need it to go faster than the speed of light  to patch our model.

Why are we looking for Dark Energy?  Because without it the model fails.  Lets stop putting patches on a dead theory and take a new, fresh look at the universe.</description>

		<description>I understand your explanation, you&#039;re right. Sometimes it is not easy too understand topics about cosmology.

Keep it up your good work!

Thanks Nancy</description>

		<description>Odisea-  As stated in the article, everything in the universe will move so far away from everything else that nothing will be visible.  It won&#039;t rip apart, but will just keep expanding.  It won&#039;t rip because dark energy is a constant across space, with a strength that never changes with distance or time.  Since dark energy&#039;s strength doesn&#039;t grow over time, it won&#039;t rip the universe apart.</description>

		<description>I&#039;m sorry but I see a strong contradiction between article statement: &quot;there&#039;s good news, too: the expanding Universe won&#039;t rip itself apart.&quot;

And the words of  Vikhlinin :

&quot;Double the age of Universe from today, and you will see strong affect. An astronomer would say this may be a good time to fund cosmological research because further down the road there will be nothing to observe!&quot;

This a strong confirmation of the Big Rip scenario, then it is therefore confirmed not refuted.

Please clear it up</description>

		<description>Hiker 9965 Says: When the Standard Model fails again and we need a new force, they will contact George Lucas and ask what he would like us to call it.


Are you implying the standard model fails? 
If you ever take a class, or even watch enough lectures about particle physics, you would know that the standard model doesnt &quot;fail&quot;, it grows.  

If String Theory was ever proven correct (a long shot), it would jst be added to the Standard Model. 

If thats not what your implying, then my apologies.</description>

Hiker,
Refusing is the essence of your perception.
Ostriches refuse as well, to see what might frighten or confuse them. (I know they don&#039;t really, just using a metaphor).
I too, thought the article lacked for layman english that would explain the difference between &quot;creating gulfs between us and the known universe&quot; and &quot;the big rip&quot;. Is it saying that gravity will keep local things together so that subatomic particles never have to worry about losing their neighbours?
~~~~~
The concept of the big rip boils down to the concept that eventually space would be stretched so much that the laws of physics would no longer apply and matter would start to break down. Essentially with the removal of all of the forces, noting remains to keep molecules and even atoms together and everything gets ripped apart. The difference between that and what the article describes is that we would no longer be able to see anything that isn&#039;t local - it would still exist, but we would have no way to look at it or measure it.</description>

		<description>Last week I posted as Steve, but decided to be more creative...  

Last week it was Black Holes.  This week, Dark Energy.  I am glad these scientists are keeping busy &#039;discovering&#039; thing that don&#039;t exist.  

When the Standard Model fails again and we need a new force, they will contact George Lucas and ask what he would like us to call it.

I refuse to believe we live in a universe where 96% of everything is undetectable.

There is no way any of this is real.  the EU theory explains all this with no mysterious and unexplained forces.  EU theories are sound and based on things that can be replicated in a lab.</description>

		<description>Thank you for this great piece of news!
Though I missed somehow one important point. You say the dark matter has features of a cosmological constant which implies that    the expansion of the universe will continue to accelerate. On the other hand, at the very beginning of your article you claim that the Universe is not going to rip itself apart. Is not one of those two statements excluding the other one? It reads somehow confusing and contradictive</description>

		<description>Reading more physics is always a good idea. But so is learning the liminations of &quot;modern&quot; science. I, too, like R Kirk says, have a feeling scientist are taking a &quot;Cosmic Map&quot;, and so to speak, are writing &quot;Here there be monsters&quot; each time a new unknown pops up.

Imagine reading what would pass for a physics textbook a thousand years ago. Now imagine reading one from a thousand years from now. The difference could be as greater or greater.

Dark Matter, Dark Energy, the Multiverse, clashing &quot;Branes&quot;, respected cosmologist speaking of alternate worlds, and mirror worlds like our own, but different. I have a hunch - oh, I know, not very scientific - but none the less a hunch we are standing on the edge of a revolution in our understanding of the universe that may dwarf everything that has gone before.

I think more people should read more science fiction. We&#039;re going to need a lot of imagination to replace the sea serpents and &quot;monsters&quot; on the new Cosmic map with facts. And prepare for the possibility these new &quot;facts&quot; may sound like science fiction...</description>

		<description>What if ( i have no scientific basis for this, so it&#039;s just a thought) that even though the expansion keeps on going &quot;forever&quot; there might still be a big crunch after all?

It may be possible, if dark energy causes a velocity(v) tangent. As matter is pushed more and more towards c you see an asymptotic curve forming in a graph. If you then also picture the universe as a globe in which our 3 dimension represent the surface of the globe, any matter passing the other side of the globe relative to the point you are standing, v would immediately negate itself, ie from 10^7 to -10^7 or 10^5 to -10^and the matter would also be coming towards you then. Dark energy would start slowing it down again, until gravity takes over and pull everything back into a big crunch.

		<description>&quot;Read more physics and less science fiction&quot;
&quot;Nothing can reach C for starters.&quot;

How about I read science fiction by physicists such as Benford, Baxter, and Forward?  Am I then straddling the line enough to not be boxed in by preconceived notions created by our currently limited understanding of the universe?</description>

		<description>Shaun asks: 
&quot;could I actually hit the brakes and stop, watching our solar system and galaxy drift away from me at the rate of the universe&#039; expansion&quot;

I&#039;ve been doing this kind of thing at college, with OTHER ssolar systems and galaxies.... by calculating the redshift.

My attempt at explaining how I see it working probably stinks a bit....  ;) 

As long as you are part of our galaxy, you won&#039;t see it drift away.

If you were watching from somewhere in the Andromeda Galaxy, you&#039;ll see our own Galaxy APPROACHING.

See, these are movements of objects within space, relative to WHERE you are...
.....as opposed to....
the space within which the objects move, expanding, relative to WHEN was the last time you looked.

Ah, well, I tried....</description>

		<description>I have a question. If space is actually expanding, would it be possible to stop yourself from moving with the expansion?
For instance, if I grab my space ship, fly towards the moon and &quot;stop&quot; half way, where I am no longer making progress toward the moon and no longer receding from the earth and remain in a constant with the two, I&#039;m essentially only stopped in relation to those and my solar system.  But could I actually hit the brakes and stop, watching our  solar system and galaxy drift away from me at the rate of the universe&#039; expansion?</description>

		<description>&gt; Clear
&quot;since when scientists have exchanged science for superstition?

so now every time that we fail to understand a phenomenon, well just associate some weird nick name to it hoping that should explain it…&quot;

&#039;Gravity&#039; in Newton&#039;s day meant the opposite of &#039;levity&#039;. It also had a sense of &#039;weight&#039;. Newton used the word to describe some invisible spooky action at a distance and theorized that this was what was keeping the moon and planets in orbit. His use of the word &#039;gravity&#039; gave rise to some cartoons in the papers on Newton&#039;s law of levity, har har har and so forth. 

Newton&#039;s theory works if he assumed the earth had an average specific gravity of about 6. This is a lot more than most of the stuff you find on the surface, so he had to suppose that the heavy stuff had sunk to the middle to get his theory to work.

Yep. We&#039;ve been doing this sort of thing for some time, now.

It works, even when it doesn&#039;t work. The &#039;big rip&#039; theory was a big extrapolation from some rather scanty data. However, unless you publish ideas like that, then people who might come up with a disproof are not likely to do so. It seems like they have, and in doing so they have drawn our attention to the &#039;arrested development&#039; of the universe. This in turn may get modified, but the general trend is onwards and upwards.</description>

&quot;Read more physics and less science fiction&quot;

Their are some good ideas in Science Fiction.

A lot of physics is only theory which may as well be science fiction anyway as we know little or nothing about particular areas, the fate of our universe would be one of those areas where by we know little or nothing and no one here in the present time will ever get to say I told you so because we will not be around to witness proof.

So even Hunnter may be correct.</description>

dark matter, dark energy... whats next? dark aliens that we cant see, detect nor study are causing all the weird stuff to happen...

that&#039;s simply us failing to justify our incompetence in physics, our academic fields need a deep cleaning.</description>

		<description>edunuke says:
&quot;Read more physics and less science fiction.&quot;

You write harsh words. Let me have a closer look... you say
&quot;nothing can reach C for starters&quot;.
That&#039;s true, but it&#039;s a bit like telling a child &quot;don&#039;t do this&quot; and leaving it at that, resulting in a puzzled and cranky child - I&#039;ll try and put it into a phrase that explains it a little better: &quot;Accelerating massive objects or particles to reach c would require infinite energy - hence, if Relativity is valid, it cannot be done&quot;

The &quot;Big Bang&quot; was not an explosion, resulting in bits flying off in all directions from one point. Space itself began expanding.

According to &quot;Inflation&quot;, an object in an expanding space can indeed recede from an observer at greater than c. See, it doesn&#039;t need to accelerate. Space itself expands.
And then the object becomes invisible to the observer. 

Even though I have read quite a lot of Physics, it gets too complicated for me from there on, but... there&#039;s even a name for all the unusual phenomena caused by this effect: &quot;The Horizon Problem&quot;.</description>

		<description>So Hunter... 

That means that our whole solar system 
could be, like one tiny atom in the fingernail
of some other giant being. This is too much! That means one tiny atom in my fingernail could be... Could be one little... tiny universe.
  
                   
Could l buy some pot from you?</description>
