Apparently there's someone in CERN arguring that the universe isn't expanding....

This is one of those "I can't tell if this is crazy inspired or neutrinos breaking the ftl barrier" things to me, is there any physicists that can weigh in on this?

If its true.... well new evidence leads to changing of opinion and whatnot, but occams razor under this theory rules out Dark Matter/Energy as I understand...

Im not a physicists, but i play one on Eve.
The expanding universe theory is based on the idea that the light spectrum is a measure of velocity and distance. If that theory worked correctly as Hubble believed, a car would change color as it drove away from you.

And the new point is about atomic decay giving off false redshift depending on initial energy content and time. Time being a function of difference in this case, we see something form 7 billion years ago today as heavily redshifted , and closer as more lightly redshifted. End result is indistinguishable from what I understand, but my knowledge of Physics breaks down at this level Oops

Hubbles red shift = distance has amojor flaw in that he pre-assumes knowledge of distance that we don't have to prove red = distance.

"I have a theory that red means farther away so I'm going to look at space through this telescope. Oh look I see red spots, therefore, they are farther away."
"How do you know that they are farther away, thereby proving red = distance?"
"Because they are red, silly."

It's the equivalent of the same argument that Bible is true because the Bible says so.
Eidt here: The problem being, Hubble (nor anyone eles) did not have a hard fact, per-determined distance of the stars when applying the theory of red shift to distance. To know whether that red star is in fact 7 billion LY away and not 4 billion simply becuase it's red, you first have to know for a fact that it is indeed 7 billion LY's away.

It's also been shown that light passing through light can shift the color. The idea was thrown out there when i was in school then fadded away, but as our space scopes get farther out and getting veiws from a different perspective instead of a fix position, were finding out that yellow star isn't a yellow star, but 2 different color stars close together bleeding light.

I've never had to much faith in the red = distance theory. The stars and galaxies burn out and die and are reborn, they have different mass and burn hotter and brighter then others. Always seemed to me red shift was a better gauge of mass and age, then distance.

Cosmic red shift is not the only way to measure distance or the cosmic expansion on large scales. At the time this red shift was discovered the astronomers and physicists basically had no way to tell if this was do to expansion, there where other possible explanations. Today there is a whole range of other ways to calibrate this data.

Also remember that if you look out into the universe and look at a galaxy in 6 Bil ly, we see this galaxy in the state it had 6 Bil years ago because the light it emitted then is just reaching us now.

So we can directly observe the past if we look at galaxies far away. If there is expansion and the universe had a beginning we would see that those galaxies where closer together in the past and we would see how they developed and change their composition as we get closer to our time. And that's exactly what we observe.

There is a overwhelming amount of observational data that supports the expansion and the big bang theory. To suggest that some not yet peer reviewed theoretical paper trashes this body of knowledge is a bit out of proportion. But it makes for a good story in a newspaper and as always there will be a truckload of layman that write in the comments they knew this for years but those dogmatic idiot scientists would not listen.

When I was a kid, I remember looking at the stars and wondering if the UFOS I managed to see twice in the sky were going to take me away from all these lies and deceit of existence.

Then I grew up and found out everyone around me wanted to escape faster, harder and much quicker than me from their own existence, and then I realized my own UFOS were other peoples Money, Lusts, Envy ,Greed ...

That´s when I knew the Universe was simply Mankind, and Mankind the Universe.

We expand, so does the Universe, we try to flee , within or without, so too does the Universe.

We Live and Die, so too, does the Universe.

Any other notion to the contrary would simply be ... lies.

To say the Universe is static, in my own meager understanding is as much a Lie as saying we are confined to whatever imaginary set of laws we want to adhere to or confine ourselves into.

Mathematically, from our view point, it's the same thing, having photons generated at shifted energies due to different initial conditions, or perceived as shifted due to speed, the end result is still the same.
Not even sure yet how we could tell which one of those is true at this time, and that type of experiment is not exactly something to think up in a hurry, but I bet somebody will try to come up with such an experiment eventually.
It never hurts to try and explore alternate possibilities whenever mathematically sound.

It does. But not enough for you to notice with the naked eye.
For the average person, something would need to move away at a speed of at least 25 million kilometers per hour (or, if you prefer, roughly 7000 kilometers per second) to really notice a difference.

On the other hand, for SOUND, it's a lot easier to notice. You can easily hear the difference between the sound of an approaching and departing car.

I have yet to see a Dramiel change colour as it flies past me at about 11km/s - does this mean I am a below average person, or is this an issue that CCP needs to address? I guess it would be a complex problem, especially in high traffic areas, as there would be so many different perspectives... Oh wait, you're talking about RL.


The fastest RL ship is the Helios 2, which reached 69.4444444445 Km/s, what a piece of crap!

Hubble was actually testing the existing methods to estimate distance when he stumbled upon the annoying red shift mistery.

"Why do cepheids in other galaxies look redder? And why the fainter/farther they are, the redder they are too?"

That was the mistery Hubble discovered and explained.

11 km/s is still a lot slower than 7000 km/s Lol
Also, if you look carefully at the warp tunnel while in transit at warp speed, you will notice the FRONT areas lightly tinged blue, and the REAR areas lightly tinged red - so there actually IS redshift and blueshift even in EVE Twisted

I was reading when my mind fixated on the "100 inch Hooker Telescope".

Youre telling me that there is a telescope dedicated to viewing amazonian prostitutes that are over 8 feet tall?!?!!?

My god.. the implications of this alone are more staggering than the thought of a non-expanding universe.

Since the cessation of their usefulness is imminent, may I appropriate your belongings?

I believe its devised to prove expansion theory on both the small and large scale.

this is spot on. As it mentions in the article the current accepted theory explains the evidence, enough that the theory is well accepted. What no one mentions in this article is that there are a lot of problems with the big bang theory atm, evidence that we should be able to measure but haven't. From this short blurb I am guessing that this view may allow an explanation for this missing evidence, much similar to how parts of string theory allow a sufficient explanation for the inconsistencies between general relativity and quantum mechanics.

The problem with both is that at this time we have no method of proving either true (string theory and mass change yielding a wavelength shift). I might think on this more later, but if nothing else it is interesting Smile

Hold on a minute, here! I thought red-shift = "going away from", not distance, and the more red-shifted, the faster it was going away from us. The inverse of that is blue-shift = "moving towards to", again not distance, and the more blue-shifted, the faster the object is moving towards us.....

I thought distance was measured by calculating how fast an object moved across the sky in relation to the other star's locations, and the number of degrees that the object moved compared from the last time it was measured, from Earth's view point.

Watch this space.  New exciting signature in development.

And how would you know if it's heading towards or moving away unless you the distance?
What I still havent figured out is, how do they know the distance of the stars to decipher whether red-shift is true? It's not like we can go out with a tape measure, check it and say "7.5468 LY, hmmm....OK, Hubble, what's the color now?"
We know haw far Jupiter is, we've sent probes there. We have hard numbers to check theories against. But that little red dot way oof there? Not so much.
