They just pulled it out of their asses. I can't see how you can calculate something like that.
[QUOTE=Fourm Shark;37644840]Assuming it would diminish.
In fact, the universe is expanding [I]faster[/I] every minute. Dark energy is overpowering gravity.[/QUOTE]
If the bodies have reached "escape velocity" then they would never come back even if dark energy suddenly disappeared anyways.

Quantum entanglement is another sciency thing in ME, although they use it for communication(it can't be used for that in real life).
There were some other things that were grounded in science. Generally Sci-Fi writing teams have a "scientific advisor" who throws out scientific concepts for the writing team to use to make the story more believable.

"how can a human calculate a trajectory that we can launch a rocket in to land on the moon?"
"how can a human possibly figure out what atoms are if we can't see them?"
"how could we possibly come up with a method to figure out statistical significance of a data-set?"

They are 99.996% sure that what they detected was a legitimate result and not an anomaly caused by equipment taking wrong readings.
Back to dark matter, doesnt this dictate the fate of the universe?
I mean, with dark matter the universe will eventually contract to the big crunch
Without dark matter the universe will expand and cause the heat-death of the universe?

He has a PhD in Rectal Data Extraction.
I don't really get it. Didn't calculations already show us there's gotta be more stuff in the universe than we can detect, and people just gave that undetectable stuff (that's GOTTA be there because math) Dark Matter/Energy?
Did they re-check those calculations just now or confirm its acceleration effects? That effect's always been attributing to Dark stuff IIRC because of certain proportions and they basically had no other candidate for the source of this phenomenon.
I feel really stupid now.
[QUOTE=amcfaggot;37642329]My question is, how significant is that additional .004% in terms of astronomical findings?[/QUOTE]
It's impossible to be absolutely sure about anything that is testable, because no matter how much you test it to see if it's real, a SINGLE test that shows that it's false will make it all come crumbling down. The only things we can be absolutely certain of are direct observations, such as two objects with mass attract each other, etc. These are known as Scientific laws.
When you get into WHY two objects with mass attract, then it becomes a theory if you've tested it enough. This is because it's an explanation; and explanations can be disproven.

So, let's say I have an instrument that will beep when it touches water, and it works pretty well. After extensive testing, I discover that roughly 10% of samples, it will give us an inaccurate reading (A beep when there is no water, no beep when there is obviously water).
We say that this instrument has an accuracy of 90% (This is a bit of a fudging of how accuracy is determined but you get the idea). The same will apply to
Let's say I launch it to Mars and it sends back a beep. We can then say with 90% certainty that there is water where it landed. There remains a margin of error, because we know that the instrument is not perfectly accurate.
Now, for dark energy this is a little bit more complicated, as we can't directly detect it. We can, however, confirm hypotheses that directly necessitate its existence. If I come up with a hypothetical particle, we'll call it the Hardon for the sake of vulgarity, that can ONLY exist while conforming to our modern understanding of the universe if dark energy exists, then the detection of the Hardon would indicate the existence of dark matter.
The same problem with the water detector arises with whatever instruments were used to detect the Hardon, and we must add the potential probability that the older theories it is built on are wrong.
Scientists don't rely on simple "This doesn't work 10% of the time" analyses, instead using much lengthier statistical analyses of large amounts of data, to get a much better accuracy.
If I left out anything important to this explanation please correct me.
I must say, I'm impressed with how eager you humans are at finding out my true identity. Unfortunately for you, it is going to take several radical paradigm shifts in science before you even get close to figuring me out.

[QUOTE=geel9;37642143]How exactly do we know how quickly the universe is expanding?[/QUOTE]
Google for it. In principle you look at supernovae of type IA which behave very similar. They are like a intergalatic measure. By looking at their brightness (all are very similar), you determine the distance (as farer away, as lower the brightness is). By looking at their color-spectrum, you can determine the the velocity of those supernovae moving away from you via utilizing the Doppler-effect. So you end up with a map of stars at different distances moving away from you at a certain speed. With this you can calculate how fast the universe expands and if it is accelerated (which it is) or not.
