back to article Boffins on alert: Brace yourselves for huge gravitational wave coming within a decade

The most violent gravitational waves in the universe from supermassive black hole prangs will be detected to within ten years, according to research published on Monday. Gravitational waves were predicted by Albert Einstein and finally discovered in 2015, a century after his theory of general relativity was formalized. Ripples …

In short, the gravity of the situation eludes us.

Any chance of building a giant surf board ark to get off the planet - we've left it too late for a B-Ark as at this point we're outnumbered.

Never ever surf something that travels at the speed of light. It takes no time to get anywhere so the only thrill you get is when you wipe out at infinity and try and work out how to get home.

What's the problem? Did you forget to make your reservation at the The Restaurant At The End Of The Universe?

That process could take longer than the current age of the universe,

I'll get some popcorn. And perhaps some marshmallows; could be a long wait.

So, that'll be not just Eddy's sofa, but a couple of easy chairs as well, a side table plus a reading lamp materialising on Lord's Cricket Ground then.

you basically have a 100 percent chance of detecting something in 10 years

It can't possibly be a 100% chance, for something that is only *predicted* to happen and has never been detected before.

They might say their models show a 99.99% chance that everything will be aligned for an event the model predicts - but there's always a chance that something in the model isn't what they expect, or something in the universe isn't what we expect. With our current state of knowledge, 95% of the universe isn't even observable yet.

Of course, if in ten years' time this signal isn't detected, we will have learned something new, and that's good. But it is pretty arrogant to say with certainty now what may or may not be observed.

@AC. Solo,, what you are saying, is the 100% certainty is certainly uncertain? That's certainly interesting.

The 100% certainty is certainly mathematically uncertain.

The way I read the article is that these collisions are happening all the time but our current detectors are not powerful enough to pick up the impact of gravity waves on pulsars etc. The article is then suggesting that in ten years time the detectors will be sensitive enough. Again a rash statement but this interpretation shifts the focus from the actual events occurring* to the way we detect the events once they occur.

*I think the argument is that as the universe is so big, all possible events are happening all the time if we just know how and where to look.

One of the sources in the text of the article elaborates on this exact point more clearly whereas the article vaguely alludes to it; right model (100%), wrong model (<100%) then go back to the drawing board. Communicating science to the public sometimes glosses over details.

So all we have to do is to work out *exactly* how improbable it is....

So how many points do you score in intergalactic bar billiards if you pot one supermassive black hole into another?

No points - but I'd imagine there is a market for the video in Germany.

Huge ripple (Mmm! chocolate)

Headline: HUGE GRAVITATIONAL WAVE

Article body: "large ripple"

Perhaps the wave's so big it's got ripples on it?

They're not ripples - they're bow waves from the plancs.

Sounds like yet another cause of the wife's headaches, first it's flashing lights, then it's the weather (is it going to rain?), then it's the air pressure ... soon it will be ... "Sorry honey, not tonight, that gravitational wave has upset my stomach..."

Watching for light to detect gravity wave?

I think that was what was said.

Assuming gravity waves travel at the speed of light then as you see the light blink you know the gravity wave just went past.

Obviously missing something, but what?

The Universe Is Doomed!

What other conclusion can I draw from the statement that it is virtually certain that we will detect an event, within the next ten years, that may take longer than the age of the Universe to actually happen?

Well, perhaps not; perhaps the approach of two supermassive black holes prior to their indefinitely-delayed collision will still be detectable by the means outlined, anomalies in the observed timings of pulsars. Still, this again illustrates the pitfalls of science reporting in the popular press.

The Reg Blocking it's own ads?

That screenshot of The Reg does not have the usual cruft of border adds and such (I'm currently seeing IBM). Home page loads horribly until you put in something like Ghostery, disable the 15 trackers on The Reg's home page, and then... yeah, you can see the speed improvements in Quantum.
