If we found an exoplanet with signatures that suggested the atmosphere might support life, billions and billions of astronomers would be analyzing light/gravity/etc from every possible angle.
So it isn't like it wouldn't get unprecedented peer review (remember how initial lander photos of Mars showed a blue sky, as an example).
And the "dark energy" only happens in between galaxies. Doesn't happen in our galaxy or our solar system or on our planet.
And who knows, maybe it is right --- then again you hit on the idea in the 1800s that the sun might be made of coal because we viewed coal as the most efficient fuel we could understand.
Dark matter and dark energy are kludges thrown into an equation because the equation is incomplete.
Like a formula with 2 unknowns, X and Y, with undefined values for each.
Dark matter might as well be called "behavior of gravity or a gravity-like force that we don't understand or observations that could be wrong or misunderstood so far".
Dark energy might as well be called "Looks like we might have expansion if we understand the observations right and since we don't understand this either, let us say there is dark energy".
Do you think 96% of the universe is dark matter and dark energy or do you think that more likely our understanding is 96% incomplete or that some ideas of measurements at great distances are terribly wrong due to something we are assuming (and shouldn't be) or something we didn't think of so far or that our ideas of the fundamental forces still have some major discoveries?
We have some great and compelling ideas in cosmology and physics, but we are not so far along that we don't have much more to go, hell we've supposedly observed quark quartets -- which I guess aren't supposed to happen --- so let's assume the safe thing = we have a lot to learn about the universe still.
Many movies don't have a meaningful plot --- as Alfred Hitchcock called it, a common practice is begin a movie with a "McGuffin".
http://en.wikipedia.org/wiki/MacGuffin
The McGuffin is something that begins a quest or series of events but ultimately doesn't mean anything. An example, is a quest to find the Holy Grail or to find the Maltese Falcon or James Bond needing to find a device stolen that can [insert what it does] or Bob owes a loan shark $5000.
Video game plots generally don't help the video game, some of the outstanding games tend to be the very few that do (and some of the very few that have about no plot).
But the point is, many movies only have a superficial plot.
A universe with matter and a finite age better have background radiation.
It doesn't mean the origin of energy --- and then later matter --- in the universe started from a small point-like area.
We don't see cosmic expansion within the galaxy, we only see this on large scales using our idea of how we interpret the measurements. If the universe is making more space between galaxies, why is this only happening at great distances? Why isn't the universe making more space between the Earth and the Sun, as an example?
Last time I checked, consumers paid for their internet access.
This is the right for an ISP to throttle and establish even more monopolies and cartels where Googles and Netflixs and Facebooks of the world have more internet rights than others.
There needs to be some sort of internet bill of rights, some sort of privacy bill of rights in this country. As it is --- there are legitimate web sites that happen to be right-leaning sites that are censored by Google -- and while I am not personally very interested in those politics, we are at risk of a world where the Googles and Facebooks and Verizons and Time Warners are agents to enact the government's will and or censorship, while calling these companies "not the government" and denying that there is any free speech or privacy rights for the consumer and the citizen.
And Google and such advise the government, make campaign contributions, etc. --- are we sold down the river? Where is the silver lining or positive angle in all of this?
Your post provides some interesting information about the Bullet Cluster that I will research.
And yes, "tired light" is a long shot for certain. I was more illustrating that at great distances there are greater unknowns.
Clearly, observations support a Big Bang and, as an example, discount a Steady State Universe.
But those aren't the only possibilities either, and our understanding of cosmology is relatively primitive compared to what we will know 500 years in the future.
No doubt a few centuries down the road we may discover more than a few curve balls about how the universe or fundamental forces work that we didn't expect.
The Big Bang is currently the shoe that fits best. But science is to question and learn --- maybe one day another shoe that we don't foresee today fits better.
There isn't actually much evidence of the Big Bang directly, it is implied as a way to explain the red shift we see of distant galaxies (red shift = it seems like remote galaxies are moving away from us).
But alternate explanations do exist and as an example, we can't account via our current understanding of gravity why our galaxy rotates the way it does ---there isn't enough mass (hence dark matter theory, likewise we have no direct evidence of dark matter nor dark energy) --- perhaps gravity is more complicated on larger scales. Or perhaps something is missing trying to use certain types of supernova as standard candles (we could be miscalculating the red shift somehow and it is not entirely possible to dismiss something similar to "tired light").
The short version is the farther back we go in time, the more we have to guess --- and no doubt we are still doing a ton of guessing today. Maybe 50 years or 5000 years from now, our errors will look trivial in hindsight but the science of cosmology is a continuously emerging science as our tools and ideas get better.
I'll call gravity "solved" when we understand or disprove the idea of gravitational waves, for one.
Also the matter in our universe could exist from some other process than a "Big Bang" because as pointed out why did all of our energy become matter and almost none became anti-matter --- couldn't the matter in the universe exist due to an oddball pair-production event? That being said, star formation and spectrum analysis support the idea of a universe of very finite age (early stars made of simple elements like H and He, etc.) --- but old ideas of the Big Bang assumed a 4 dimensional sphere or hyperbola and measurements seem to contradict that (the universe appears flat) and we rely solely on the red shift as evidence of cosmic expansion --- what if an alternate explanation exists??
No our science of cosmology in still in its infancy and we are likely wrong about a great many things, still.
HTML was meant to be easy and accessible to all. At least HTML 2 and 3 and maybe even 4. But stick a fork in the HTML dream, it died a long time ago.
And everyone at least knew what a 404 was.
Now we need to eliminate those to monetize things or redirect to a page full of Facebook javascript or other ass-raping javascript to destroy privacy or some page with at least some ads and hopefully 3rd party cookies and a hidden tracker image.
Or something?
We live in the age of the "EVIL INTERNET" --- the internet isn't some awesome thing here for us to explore, the internet is an evil corporate device meant to screw the user over by any means possible, whether or not that involves lying "Hey it isn't a 404! Here, go to this evil page you aren't looking for so we get ad displays and our javascript can privacy-rape you!"
Welcome to the 2014 Internet --- the *cannibal internet* that lies to you, tracks you and eats all your rights away so some companies can make a 3/100s of a penny! And if you don't support this, you are part of the "problem".
I agree with the "prove it", but isn't the current big bang theory that initially everything was energy for a short while and there were no particles, therefore neither matter nor anti-matter, initially? If so, the idea of the article of when and why and how the imbalance occurred seems very relevant.
And the fail is you misspelled "misspelt" attempting to do a spelling correction.
The real truth is that Occam didn't have a razor, those didn't get invented until several centuries later, and that a correct translation is "Occam's Lathe" but the Greek translation to German got mistranslated into English, as I'm sure you heard, and so we go....

It is bad enough you responded to derail troll. Worse that someone didn't mod both of you offtopic.
Someone actually hurt this more by upmodding your reply to a derail.
This is why our political system is broke, try to point out how Net Neutrality is vital, some goon brings up healthcare.
Then someone else who thinks he is smart, agrees to change the conversation to healthcare to respond to a goon.
BAM! You've been suckered and taken your eye off the ball: The ball is Net Neutrality.
Don't take your eye off the ball.

All the predictions in the article are with overwhelming "won't happen" odds.
There is no almost value in predictions that are negative predictions (i.e. "We predict this won't happen".
Most people can see a number of things that won't happen, the value of predictions is identifying things that WILL happen.
Dude ... whatever that overly long diatribe was about, I'm sure it has fuck-all to do with a free web browser.
Get a grip, a freebie web browser isn't the same of a can of tuna with dolphin meat in it or whatever screed you wrote a baby-bible over.
You mean *DWARF* moon. Because in order to be considered a *real* moon, it has to clear its orbit of debris.

Even since I was 3 or 4, almost every time I had to go #1 I used an apparatus that I called a "zipper" and used its "slide to unlock" feature.
I agree with the "prove it", but isn't the current big bang theory that initially everything was energy for a short while and there were no particles, therefore neither matter nor anti-matter, initially? If so, the idea of the article of when and why and how the imbalance occurred seems very relevant.
We wouldn't be calling it anti-matter, we would just call it "matter" and would be still asking the same question.
So there are really only 2 scenarios.
And the fail is you misspelled "misspelt" attempting to do a spelling correction.
