Perhaps you could do yourself a favor and use better sources when it comes to anything concerning science. Did you read all the corrections to the original they had to make?
Protip: Accuracy and rigor should be the focus when reading about science, so don't choose popular entertainment formats.
It was an article that popped up on facebook

This was the edited version of the original particle I read

So this is real then?
sorry fat fingered was I was typing.
what I meant was so this is real then in your mind airbrush?

If you provide some reference supporting your statements some memeber may take a look. And refute statements about any asteroid collision in the near future.
I am trying to find the articles, I saw them a few weeks ago while I was suspended.
i guess I am looking more for information on this specific asteroid, and how trajectory is calculated and how much can we trust those numbers

Hi all some questions
for the asteroid on April 30. According to NASA it will be 16 times further than the earth to the moon.
1- How can they know this for sure?
2- How do we know they are being honest with the distances?
3- are they the Only ones able to make these calculations?
4- Several news sites had articles that it would hit and this was secret info from NASA?
5- another site claimed that the Coronavirus was brought up to keep people isolated because of this asteroid to avoid mass panic, so how do we know what’s real vs fiction on this?
These things make it hard to determine what is right dosent it?
thank you

Can you see it with a good digital camera, which area would you look in

I do know that at one point Betelgeuse was dimmer than Bellatrix and now it seems to be brighter than it.
i guess no supernova just yet

But sometimes it goes back to being brighter and sometimes dimmer.
There is a long term graph here: https://twitter.com/EricMamajek/status/1208176941502590976?s=20
It doesn't look that unusual. It appears to have got this dim in the 1980s. And presumably many times in the past. It is a variable star. So varying is what it does.

Looks like the dimming may be over:
I assume the brightness phase is also about 420 days?

If you’re incapable of figuring it out on your own then it’s probably best in your case to stick with factory defaults
I am sure I can figure it out now that I know where to look
thank you

Connect to the router using a web browser and search for QoS settings (Quality of Service). Check if it has an option to enter the MAC Address.
I think I saw that somewhere

That would be awesome to see that, last election I actually thought Hillary would take it.
Does anyone feel that the whole impeachment puts a damper on trumps possibility to take a second term?

I totally understand that but when push comes to shove will she have enough to be trump for presidentcy

Yes but with the women in the mix, I am all for a women president but is the USA ready for that. Trump still seems to have a good stronghold

As you can see from the graph, sometime the bright part of the cycle is dimmer and sometimes it is brighter.
Sorry I may not have asked my question properly
when it normally goes through it’s 420 day dimming phase then goes back to its brightening phase does it actually ever go back to its original brightness?
ah I think I saw what you meant sorry. It usually goes back to original
now question it seems to have dimmed a lot more than it normal would in it previous cycle but I did read this was over 25 years. But I believe I also read that this is not the dimmest in the past 100 years is that true

Yes, most of them are still active
That’s pretty cool, so dead galaxies and live galaxies can be situated is the same area of space
how is that possible?

So my post was closed before I can respond to your comment
Good question, do you mean if Betelgeuse's next peak in brightness will be as bright as previously recorded peaks? I do not yet have an opinion:
I made a plot from Betelgeuse brightness data from 1997. From that we see that the maximum brightness in each cycle does not deviate very much. So given the lifespan of stars and the rather consistent behaviour in the data I've available I have no reason to predict that anything special is happening in the next cycle. But note that the last minimum deviates a little and that we at this time we are near the minimum brightness, It has just recently been suggested that the brightness is increasing again. Hence I will not try to predict the next maximum brightness from recent data yet.
Data and plot thanks to https://www.aavso.org/
From what I see in the graph and the twitter link you provided , it kind of looks like it is brightening again.
question I have is since it goes through these phases of dimming and brightening during the brightening phases does it go back to its initial state prior to dimming or is the brighteness lower than previous?

Adding some information: just as in denser regions, voids also contains galaxies that does not form stars anymore (dead galaxies):
https://academic.oup.com/mnras/article/386/4/2285/1467362
The conclusions are that the amount of dead vs star forming galaxies fits mainstream models and simulations.
More details available in the linked article. The article is rather old but may be an interesting start for further reading about void galaxies vs galaxies in denser regions and galaxy formation and evolution.
So basically voids seem to hold galaxies that also still create stars then?

From article, bold by me:
So the article does not contain what you say. The article seems more about speculations about implications of research not yet confirmed.
Yes but it says they found different constants in different parts of the universe
When my colleagues and I looked at the spectra of gas clouds in the early universe and compare with the same elements measured in laboratories on Earth, we saw very slight but significant differences,” said Webb. “We only know of four forces in nature: electromagnetism, gravity, and the strong and weak forces acting within atomic nuclei themselves. And at least one of them, in other regions of the universe, now appears to be different from that on Earth.
By combining the data from the two telescopes that look in opposite directions, the researchers found that, 10 billion years ago, alpha seems to have been larger by about one part in 100,000 in the southern direction and smaller by one part in 100,000 in the northern direction. The data for this “dipole” model of alpha has a statistical significance of about 4.1 sigma, meaning that that there is only a one in 15,000 chance that it is a random event.

Just cam across this article that the fine structure constant is different and is changing all over the universe
they talk about different alphas depending where you look

Unfortunately, scientists have so far not detected any life, intelligent or otherwise, present in any single one of these galaxies.
I meant are they still forming stars
not that it really matters anymore

Good point regarding simulation, caught my interest:
@Bmpbmp1975: There are theories that voids can merge to form larger voids. Here is one article with short animations and references to papers: https://www.nature.com/news/vast-cosmic-voids-merge-like-soap-bubbles-1.18583Another short article that specifically covers some ideas of the formation of Boötes: https://web.archive.org/web/20071119011039/http://findarticles.com/p/articles/mi_m1511/is_n8_v16/ai_17253874
So are the 60 galaxies alive or dead galaxies?

Really cool how they have finally captured an image of a black hole
