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 …

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.

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.

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.
