It could. But most of time, exciting new discoveries fade away with more data.

I think that this is something being looked at since 2018

Just now, Strange said:

No implications for us. (It isn't coming to get you.)

But, if it turns out to be correct, then it may cause some bits of our theories of physics to change. The "fine structure constant" is assumed to be constant, as the name says. If it turns that it has changed very slightly, then we would need to modify theories to explain or incorporate that. It could, I suppose, make a slight difference to theories about the very, very early universe.

I get it anytime something like this is found it could change our theories and possibly our text books and stuff

That is about the measurement of the fine structure constant getting different results in different directions (i.e. not being isotropic).

Thank you, still don’t get what the implications are if they are different 

Sorry this quote threw me off 

So the universe may not be isotropic in its laws of physics – one that is the same, statistically, in all directions. But in fact, there could be some direction or preferred direction in the universe where the laws of physics change, but not in the perpendicular direction. In other words, the universe in some sense, has a dipole structure to it.

I am trying to understand if this article is talking about expansion rate different depending where we look or it is is something totally different?

I can try to clarify that. To get the discussion in the right direction; do you know some basics about probabilities? For instance the difference between a coin toss with chance of 1/2 to get a head versus a regular dice throw with 1/6 to throw six? 

(assumes fair coin and fair six sided dice)

Ok now you lost me lol

Gotta love Brian Cox, his series from 2017 is still making red on express.co.uk. Is he for real or just a celebrity who created a video?

His title claims universe can end at any minute but when you read the article by any minute he really means in a very very long time.

But, Professor Cox confirmed it would be a long way in the future before something like this happened.

He added: “The time-scale for vacuum decay is many times the age of our universe, so it’s not going to happen tomorrow, but it’s still disconcerting to think that our universe isn’t the stable, eternal home we once believed it to be.

I don't think you understand how science works.

Some people made some measurements. They suggested one reason for the data could be that the universe was not expanding at the same rate in all directions. If you read the paper again, they also pointed out that there are several other possible explanations.

Ethan's article is pointing out that these other existing explanations are more likely to be the case. In particular, he casts doubt on their assumption of a tight relationship between temperature and luminosity (as I pointed out when I posted that link before).

Note that science is all about possibilities and what seems to be most consistent with the evidence. It is not about truth. And not all scientists agree about what the best explanations are.

From the article linked from your second link:

• This finding could be a sign that the universe is actually “anisotropic” ...
• This possible evidence for anisotropy ...
• Doing so allowed the researchers to estimate the cluster’s x-ray luminosity—and therefore its distance
• allowed Migkas and his colleagues to probe potential deviations in the universe’s rate of expansion
• thus potentially closer or farther away than expected
• "We managed to pinpoint a region that seems to expand slower than the rest of the universe and one that seems to expand faster,” Migkas says
• Therefore, the situation is still vague.
• Perhaps, somewhere in the intervening eons
• Alternatively, the universe might not be lopsided at all
• The most obvious explanation, of course, would be that the apparent asymmetries in cluster spacing are because of flaws in the data or their analysis
• Such inconsistencies suggest correlations between a galaxy cluster’s x-ray temperature and its luminosity are not as clear-cut as researchers would prefer
• there are other potential problems to deal with
• Riess adds. “That seems suspicious!”
• David Spergel ... also suspects faults in the cluster-based measurements
• “This is a paper that is very important if [it is] true but very unlikely to be true,” he says.
• They are now looking for further hints of galaxy-cluster anisotropy
• It would be great if we knew

Do you get the idea? Nothing is certain, everything is conditional, it all needs further research,

 

I get it I am just more surprised it has been retracted so quickly within days 

So now they changed there minds about this?

A suggestion: the above quote may be more helpful than the following post:

 

I added the quote before

Who says it would be more powerful than all those stars together?

 

It the original article there was a mention made it would be more powerful

When we detected our first black hole-black hole merger, there was a brief time period lasting under 200 milliseconds where that merger produced more energy than all the stars in the Universe combined. If we can find a supermassive black hole merger where the smaller mass is more than 500 million solar masses, not only will it emit more energy than all the stars in the Universe for about a week, 

I still don’t get how our universe contains possible 1 googol of stars and this type of merger would be more powerful than all the energy of those stars together but still only become gravitational waves?

so I am a little confused. I thought Fomalhaut was a small galaxy with numerous stars example Fomalhaut A , Fomalhaut B  etc. Now the article states that Fomalhaut B disappeared but does not give information about Fomalhaut A and the other stars and exoplanets in Fomalhaut.  So are those still there or did all of Fomalhaut disappear? And yes I know they think what they saw was a dust cloud

1,344 + 20 = 1,364

1,344 - 20 = 1,324

So it's expected to be between 1,324 and 1,364 light years away. That's more than one thousand. Lots more than 20.

 

And, who says we're passing through it?

I get that now 

and I read this part which made me wonder Effects if it’s headed toward earth 

The notion that a rogue planetary body such as the Orion Nebula is headed towards Earth was confirmed back on January 25, 2016,

How about a link and a quote?

Stop being so lazy in your search for doom.

 

 

edit: I did find this - https://astronomy.com/news/2019/10/planet-nine-may-be-a-black-hole-the-size-of-a-baseball

And no, there is no doom here; unless you start assuming things that you wish to be true.

I never one brought up doom. I had read an article and it peaked my curiosity so I asked a question. Didn’t quote the article the questions were my own.

Nowhere does your quote say "the earth will start its 62 day passage on the black hole of the Orion Nebula".

You have to do better than this.

I am trying to find the part about the hole hole thing it’s a long article, but if it is 1000 ly away how are we passing through the nebula

and if you read my op I was never mentioning doom I was asking about the article that’s all. 
 

How is this 1,344 ± 20 light years = 1000 ly I thought it was  1.3 light years but what is the 20 mean then

The quote YOU provided has a link to wikipedia.

Follow that link.

It says 20 light years

The Orion nebula is not a planetary body, it's a nebula.  The Orion nebula is over 1000 ly away.  I think the web site is probably written by a 10 year old.

What do you mean 1000 light years

Will you please quote the section of the article that says: 

I have no idea what that means.

Why do you keeping searching for and asking about doom-laden scenarios?

No I came across an article and I am curious that’s all. 

So if the planet nine that was found really does turn out to be a pbh the size of a grapefruit like some scientists think. At its short distance from earth what effects would we see as it gets closer to earth? I assume like other black holes it would slowly get bigger as it consumes objects in its path?

cause if I understand right planet nine affects earth

Tip: When you see a website called something like 911truther.org you should assume it has all the scientific reliability of a Road Runner cartoon.

The notion that a rogue planetary body such as the Orion Nebula is headed towards Earth was confirmed back on January 25, 2016, when it was reported that Planet Nine was discovered in our Solar System. NASA corroborated the discovery of Planet Nine roughly 19-months later on October 4, 2017, in their report entitled, ‘The Super Earth that Came Home for Dinner‘.
 

33. October 31, 2020: End Date of Maya Calendar
34. October 31, 2020: Start Date of 62-Day Passage of Earth Through Orion Nebula
35. January 1, 2021: Start Date of New Age
 

Ok found this article online from a site called 911truther.org claiming the actual end date of Mayan calendar is really oct 31. 2020 and the earth will start its 62 day passage on the black hole of the Orion Nebula. January 1 , 2021 will be the new age. Has anyone seen this or have any clue what they are talking about?

No. And stop twisting every thread to fit your delusions. Have you spoken to your doctor yet?

In the case of the black hole mergers detected so far, which are black holes around 20 to 30 times the mass of the Sun, even if they were as close to us as the Sun is it would only cause the Earth the stretch by about 1 metre, which is about the same as happens everyday due to the moon. (They would also be only about 100km across and so not visible without a really good telescope.)

I will try and get some rough figures for the merger of supermassive black holes...

I was not twisting anything I was asking because of the amount of power unleashed
