Anton pumps out a lot of stuff and does have a gem or two and this is a cracker, the first map of the universe's background gravitational waves:

Next big thing in gravitational waves is LISA
https://lisa.nasa.gov/
We’re building the optical benches in Edinburgh.
LISA will look at a different set of wavelengths from the ground based LIGO detectors, allowing astronomers to study what happens as neutron stars and black holes rotate around each other before colliding. That will also allow us to point other telescope towards them before they collide, so we can observe the collision happening.

Ho ho. Anton pulled out exactly that infographic in his vid.
The trouble with this stuff is that it does take so long. Years of continued observation of the pulsars to get anything as complete as the microwave background...

Actually on a personal note Biffer, I understand you do a bunch of stuff in scientific fields. You don't know, or know somebody, who's into the movement of hydrated and non-hydrated ions in a water solution under electromagnetic effects. There's a patent I'd very much appreciate a second opinion on and Copilot only takes one so far.

Afraid not, not the area I work in. But genuinely, speaking to an actual patent attorney might be your best bet - they’re usually scientists who have done a conversion course, not the other way round, so you will get someone who has a doctorate in that area to look at it and advise you on things like prior art etc. And if they reckon it needs more work, they’ll know the university departments that might help you flesh it out (although make sure the contract you have with them protects your IP - some unis can be a little acquisitive).

Thanks. It's actually an existing patent I'm trying to work through, but in the vein of okay that's not quite what I'm looking for but it's given me the inspiration to go but, ah, something else is, cheers!

Is there a practical use for this in our world apart from this science and observation? A genuine question, I 100% am on board with it either way, just wondering

Well, the technologies being used will have other applications. The precision optics will end up in optical clocks for the next generation of position navigation and timing satellites, for example, or for the quantum gravimeters that are being developed in various places, and the general satellite tech requires astonishingly high precision in pointing accuracy and positioning, which might end up being applied to array telescopes for earth observation. Various bits of tech will end up in optical and quantum comms as well, as these come into common use over the next twenty years. But applications of actual gravitational waves? None atm. But it took decades for us to understand where the applications of general relativity and quantum mechanics were going to be, and nobody working on them would have anticipated having GPS, or access to the entirety of human knowledge in your pocket. So who knows,

I'm not necessarily this lady's greatest fan but this new 3rd particle type is interesting.
