The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.
“The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‘Eureka!’ but ‘That’s funny…'” --Isaac Asimov
TLDR: Depending on where we look, the universe is expanding at different rates. We can now confirm it's not measurement error.
Oh. Well. That's. Terrifying?
Uh, why?
I'm afraid of things I can't understand.
You can make a religion out of that!
don't worry, we're expanding with it!
I'm not expanding! It's just my big bones, y'know!
It's not a matter of where we look, it's the method we use to calculate the expansion. The 2 methods to calculate the expansion rate give us different results. For a good explanation, here is a YouTube playlist of videos by Dr. Becky Smethurst where she discusses & explains the "Crisis in Cosmology": https://www.youtube.com/playlist?list=PLd19WvC9yqUf5TRqYoMYxEwjT6JIDW4Zn
Dogulas knew:
I always said there was something fundamentally wrong with the universe.
-- Arthur Dent, the Hitchhiker's Guide to the Galaxy Radio Series.
Sounds more like Arthur knew...
No flying machine will ever reach New York from Paris.
One of the Wright brothers said that. It's actually my favorite quote because it always reminds me we have no idea what the fuck we're wrong about.
No flying machine will ever reach New York from Paris.
googles
Interestingly, when he wrote that, it was part of a larger quote saying virtually the same thing that you are, just over a century ago:
Wilbur in the Cairo, Illinois, Bulletin, March 25, 1909
No airship will ever fly from New York to Paris. That seems to me to be impossible. What limits the flight is the motor. No known motor can run at the requisite speed for four days without stopping, and you can’t be sure of finding the proper winds for soaring. The airship will always be a special messenger, never a load-carrier. But the history of civilization has usually shown that every new invention has brought in its train new needs it can satisfy, and so what the airship will eventually be used for is probably what we can least predict at the present.
The most exciting result of scientific discovery is "well that's odd."
This is amazing news. It's like being shown that Neutonian physics are wrong, so now we have the ability to come up with a better model, then massive advancements in technology can occur.
We did find out that Newtonian physics is wrong. Einstein got famous for it and we now use general/special relativity and quantum phsyics.
No, Newtonian physics works just fine. Unless things are too big, too small, too fast, or too slow.
At least that's what a meme I once saw said.
So it works fine on human scales, but for most of the universe it is inadequate. That means it's wrong. Quantum physics and relativity are also wrong since he are unable to reconcile the two, despite them both being the best models we have for their respective scales. We have known for the past century that we have only just begun to understand the universe, and that all our models are irreconcilable with each other, meaning that they are ultimately wrong.
Just because a model is useful doesn't mean it is right.
Agreed, but it leads to people who are less knowledgeable to draw the wrong conclusions.
Basically for just about anything you want to do on Earth Newton works perfectly fine. You can send people to the moon using nothing but Newton. Two big things you need Einstein for is the orbit of Mercury and GPS satellites. So from a pure science point of view Newton is wrong or maybe incomplete. From a regular Joe point of view Newton is dead on. By proclaiming Newton is wrong, it leads to people concluding that all science is wrong, because there is always someone working on the next iteration. So people think vaccines are dangerous, wearing masks is dumb, herbs and spices cure cancer, global warming is fake and homeopathic shit does anything except remove money from their wallets. Because what do scientists know, they've been wrong all the time in the past.
Newton is not wrong, it's just incomplete for some very niche things. And Einstein fixed all of that so we're all good.
In reality it's good to always be looking to disprove something and create new and better knowledge. But only if that's your job and only for very niche things. We've got the basics down for most things on Earth and there is no reason any regular person should doubt that.
Conversely, just because a model is wrong doesn't mean it's not useful.
It's inaccurate, not wrong. Framing things in right and wrong misrepresents scientific progress in a way that leads to ridiculous conclusions like some post-modernist post-truth philosophers came up with.
I think that's the point they were making.
I think it's better to say that Newtonian physics is incomplete rather than wrong.
Bingo. All models are "wrong", good models are useful despite being "wrong". Relativity is wrong too since it can't account for anything quantum... Relativity isn't better, it's just more accurate under certain conditions - but outside of those conditions it's more complex than it needs to be, and Newton's models are good enough.
Neutonian physics are wrong
Dangerous way of putting that since we have so many easily weaponized idiots who will carry that water, a better way to say it would be "our understanding of neutonian physics is incomplete at the moment"
Maybe Maybe there's something seriously wrong with the Universe? Why is it always US who are wrong?
Hey, it's me, the Universe. I just wanted to say, this is no longer working for me. And if it makes you feel better, sure it's not you, it's me. Please don't call.
Yay!
From my limited understanding, the discrepancy comes from the two ways to measure the universe's expansion: calculation from cosmic microwave background and calculating a cepheid variable, which uses pulsating stars (pulsars?)
Isn't it more likely that one, or both, ways of measuring are wrong? As in, they're not useful for measuring the universe's rate of expansion?
We have a very limited view of the universe so it's no surprise that our theories are often wrong or incomplete. The beauty of science is that when a theory proves inadequate, it gets replaced with a more complete one.
