Hey, SHUT UP! The "&N" stands for AND NEWS, k? ;)

In a major discovery, scientists say space-time churns like a choppy sea

The mind-bending finding suggests that everything around us is constantly being roiled by low-frequency gravitational waves


"The very fabric of the cosmos is constantly being roiled and rumpled all around us, according to multiple international teams of scientists that have independently found compelling evidence for long-theorized space-time waves.

[...]

In Einstein’s reimagined universe, space is not serenely empty, and time does not march smoothly forward. Instead, the powerful gravitational interactions of massive objects — including supermassive black holes — regularly ripple the fabric of space and time. The picture that emerges is a universe that looks like a choppy sea, churned by violent events that happened over the course of the past 13 billion-plus years.

The gravitational wave background, as described by the astrophysicists, does not put any torque on everyday human existence. There is not a weight-loss discovery in here somewhere. A burble of gravitational waves cannot explain why some days you feel out of sorts. But it does offer potential insight into the physical reality we all inhabit."

^^^ This is all way above my pay grade, but exciting nonetheless. It reinforces my layman's impression of the extraordinarily big brain that Big Al had. One of the funniest single panel cartoons I ever saw featured this former Austrian patent clerk in an auto mechanics works shirt with "Al" emblazoned on it. But I digress.

On second thought, and on a personal note, allow me to digress further. I LOVE Anandtech, and I especially love P&N. As I tell anyone who will stand still long enough to listen, I'm really an analog guy. I stumbled upon Anandtech during the time of the magical Celly 300, back when the hoi polloi discovered you could flip a few dip switches on a motherboard and -- presto chango -- have the equivalent of a Pentium 450, back when that yielded immediate real world results! But what I want to say here is how much and how deeply I appreciate the knowledge so many of you bring to discussions about the recent Titanic tragedy and the hardware implications of the Ukranian war. I salute you guys! You make me seem smarter! And as we of ATOT all know, "high levels of smartness" will get you laid, and other good things! :cool:

I suspect that once we confirmed the existence of gravitational waves, we knew we were going to find these background waves as well. And when you think about what happened in the early universe, it makes sense. Everything emerged from a violent explosion (hence cosmic background radiation), and black hole collisions have likely been happening since black holes could form.

Silver Surfer knew this all along, and has been riding those breakers for decades. Decades, I say!

I love stuff like this, but most times reading about it I feel like a gorilla in the zoo must feel-really interested in it but I have near zero actual comprehension. For those at my level of comprehension the article linked in the first post does an excellent job of explaining the basics.

We continue to affirm General Relativity using new methods, and while I can appreciate some practical applications of space-time such as keeping GPS in-sync, it still defies the "logical sense" of my monkey brain, to tell me that space AND time bend together. Or bend at all. Yet we continue to see new forms of evidence.

Largely trapped on Earth as we are, not sure how we'll make use of the knowledge of gravitational waves, but perhaps some day. For now, I would draw into question our sense of distance across large expanses. Perhaps Redshift is altered by this gravitational... churn.... and our estimates for billions of light years are wildly off. I do like picking at and trying to find flaws in theories. More information helps, one way or another.

I came looking to solve a problem on an HP Pavillion and built a 300A machine after reading about it here. I still have it in my garage somewhere in a huge tower case. My life is in my garage. I have Schwinn I got when I was seven and my American Flyer electric train my Father bought for himself for me when I was two. My interest in Physics led me to read Einstein, but it was his philosophy that I was most influenced by. He gave me an appetite to look at things differently and not worrying about being odd. He once remarked to some female selebrity, I don't remember who, when she remarked how great it woud be if they had a child with his brains and her looks, "but what if it had your brains and my looks." I first realized from him, I think, that the so called wise men are fools and the fools the wise men.

Analog is tactile and to touch is to feel.

"“What we measure is the Earth kind of moving in this sea. It’s bobbing around — and it’s not just bobbing up and down, its bobbing in all directions,”"

So...we're going to accept using one theory to prove another?
When it comes to things we can't really see or "dissect" in a lab setting, it comes down to a bunch of "intelligent guess work."

To add to what hal2kilo said: a theory here isn't what some think.

A typical scientific theory isn't a guess; it's a demonstrable model for how things work. Researchers might not have all the answers, but there's no doubt that the modelling is sound. Gravity may be a theory, but you're still going to come back down if you jump. Evolution is a theory, but there's no question humans and other animals are the product of evolution.

In this case, the theory of general relativity has held up for a very long time. Scientists only recently confirmed elements the theory establishes, such as gravitational waves, but there's been nothing that outright pokes holes in it. You can use the theory of relativity as a gauge for previously undiscovered phenomena.

You will just have to accept the fact that when you wade out into muddy water your feet actually disappear.

-Its important to point out that the actual news here is that they already had the "theory" but that they've now found the real world evidence the theory predicted. That's the news.

You're not wrong that there are a lot of things that are right "on paper" but we lack a engineering or material expertise or something else that prevents us from finding the actual evidence in real space.

The Higgs Boson was a big one that only existed in Theory because we didn't have the tech to actually find it... until we did with the Large Hardon Collider. Same thing.

Been waiting for someone to make this mistake 🤣
