I would assume the distance is a function of the event horizon / Schwarzschild radius. - If the mechanism of energy loss at greater distances is thought to be from interactions of other matter falling in, is this thought not to apply at closer distances? - Can relativistic effects such a frame dragging cause black holes to lose energy? Any other wierd ways two singularities might interact? - Is energy radiated in the form of gravitational waves, or Hawking radiation, enough to predict black hole merger? - What about after two event horizons cross, what forces are theorised to be at play during these moments? Could something interesting happen is or is it just two "point particle" singularities spinning around. - What about other geometry singularities? Rings? - Also just whats actually uncertain in the physics: the mechanism of black hole mergers, or that if they even merge (singularities combine) at all?

Firstly you watch a whole bunch of them, if the pulses change on one of them, IE it slows down and then back up again then you know some external something or other must be the reason for the change. You then look for those changes across the bunch of pulsars and you see them change in a pattern then you can model that change, and in this case the change is waves in the space between us and the bunch. The length of observations of the bunch ( years of monitoring ) allows you to measure them to a very high level of accuracy across the individuals, depending on the speed of the induvial it will be down to nanoseconds. Lots of computation of the statistics and modelling of those changes.

Another wonderful video from you Dr. Becky. I love your sense of wonder that inspires folk like me to continue life long learning at age 74. Thank you.

Over the next few decades as we gain ways of detecting gravitational waves at numerous frequencies, do you think we will be able to do a kind of gravitational wave spectroscopy? If so what kinds of questions do you think that would be useful for answering?

Dr. Feynman would be proud of all the work you do to explain the different concepts and theories in the most basic, easy to understand way. You are a gift to us.

Dr. Becky that was excellent. Long been looking forward to what gravitational waves will tell us. Please, as below, the FPP and just more please!

I love your amazing level of detail while still remaining accessible to general audiences, so do please elaborate on the "Final Parsec Problem" which sounds so emblematic of the "Last Mile" factor so prevalent in the commercial distribution of goods industries. It's telling that the "last minor fraction" of a problem can tell so much about the big picture of the whole distribution problem.

Great video, just the perfect amount of detail and really understandable explanations. ❤ Yes, please to the Final Parsec Problem video. I've not heard of that before and it seems counterintuitive that the supermassive black holes wouldn't be following the same process as stellar mass black holes.

I'm glad you showed the graphics and talked about other explanations for these observations, because all the talk of this being a "background" signal clashes with what I think of supermassive black holes mergers, which should be distinct events. Of course I understand that events like this, with such faint signals, can easily become "muddled" and form a background signal, but now I know what the data looks like and I hope more information comes out when they add up the observations from the different arrays. I hadn't heard of the final parsec problem and it does look really interesting so I hope you make a video about it. I love when physics doesn't behave like we expect: "What do you mean two massive objects don't merge? Of course they do!" (incidentally, this is what I thought when I heard that dark matter doesn't "crash" with itself like regular matter). Great video, really interesting and easy to understand!

Last parsec problem video. Yes please. Love the videos, they make the science that much more accessible. And, who doesn't like a video with Minions!

Great presentation! It's amazing how well you break down such incredibly complex topics and intersperse animations and video to explain it in layman's terms that anyone can easily understand.

I am a solo sailor…love the ocean surface swells and waves metaphor for differences in wave length and frequency of gravitational waves. A great way to visualize the phenomenon.

Hey Dr B, yet another fantastic lesson on the mysteries of the universe. This one blew my mind again. Many thanks for making such complex science so accessible and comprehensible. Cheers!

Great explanation! I was happy to hear you mention how important this paper is to Cosmology. I remember watching the release of the LIGO data back in 2016 with the entire physics department and thinking about how it was going to change the way we view the universe. Innovation will increase the sensitivity of the equipment and we will get to see the universe in even greater detail. I'm excited!

Yes on the Final Parsec Problem video! Maybe the Hawking Radiation from each interacts - though that is probably too slow of a mechanic if it exists. Maybe the 3-body problem, by throwing other nearby matter out?

Good explanations, I didn't know about Pulsar Timing Arrays but that's very cool. Since I got my bachelors degree in physics, I went on to an engineering career and lost touch with the beautiful world of astrophysics but videos like this bring me back to the university days.
