I started watching this channel before my name had "GameDev" in it (when I wasn't eating, sleeping, breathing and dreaming mathemathics.) Even when the on-screen formula was illegible, I could always understand the demonstrations clearly. Even if hitting myself in the back of my own head with a ladder walking into a shed sounds strange, they've always been able to make digesting it extremely easy by visualizing it well.

While I agree with the above comment that this is a very hard question, there are some explainable elements. Some matter orbiting a black hole have very large angular momentum relative to the singularity which allows them to continue orbiting for some time. The other important thing to remember about singularities is that they are both an anomaly in terms of space being a point of infinite density, they are also anomolies in terms of time. Things that have fallen into the singularity from the point of view of the singularity, as much as that can even make sense, may appear to us to be still falling in. Also matter that does fall in will eventually escape via Hawking radiation but as far as I know it is not known why.

@@Pain53924 A black hole IS the singularity. I assume the part you're getting confused about is the event horizon of a black hole, which isn't part of the mass of the black hole itself, its the radius around it in which gravity is too strong for anything to be able to escape. The event horizon is like the top of a waterfall while the actual black hole would be the lake at the bottom. Water going over the edge of the waterfall isn't part of the lake, yet, but its the point of no return, and that water will invariably become part of the lake soon.

Great stuff, and I hope we can learn more about gravitational waves in the future, most notably pinpoint the source of their background.

It is what a spike of energy we call a photon, perturbs through at the speed of light. When this spike of energy is much higher its actually a particle with mass, a proton ,we call it Matter. a building block of the hydrogen atom. Aether is what connects Spacetime to quantum.

One thing that I've been trying to figure out about this is how the rotation of stars in the Milky Way can be discounted, or subtracted from the result. We needed very precise measurements of the movements and masses of planets in our solar system in order to understand the positioning of the earth to do this, and I suppose that these motions are much more significant.

The orbiting of stars in the Milky Way has no measurable effect on the signal, so there's nothing to subtract here.

We're fortunate in that the orbits of stars in our galaxy are both much weaker sources and much longer wavelengths than what the array needs to detect. Galactic orbits are on the range of hundreds of millions of years. Binary star systems however produce shorter wavelengths that COULD conceivably be detected by LIGO type detectors with a bit more sensitivity than the ones we have.

Quite a lot, a single decent black hole merger can release more energy in its few seconds than all the stars in the observable universe do via light in that same time. Compared to the mass energy in the universe it's quite small, but on human scales gigantic.

If pulsars are more accurate than even caesium clocks, how can we be so sure of our accuracy in measuring them?

Because the accuracy change caused by gravitational waves is great enough. If I have a cesium clock and a stopwatch, I cannot hope to measure nanosecond changes to the atomic clock. But if I bump it and it skips a few seconds, my stopwatch can see that. To measure the base accuracy of pulsars, we merely need to time it with a bunch of cesium clocks. The cesium clocks and pulsar will 'drift' a certain, random, amount. If the pulsar is totally accurate then it will end up out of step with the clocks by an amount averaging x in a normal distribution. The clocks meanwhile will have drifted from each other MORE since any two clocks will BOTH be drifting, giving twice as much average drift. This allows us to measure something more accurate than our clocks.

In what way? Pilot wave involves a distinct, ordered waveform guiding a particle. This result indicates random, noisy waves moving through space. It's signal vs random noise. It's like saying that a stormy sea is similar to pilot wave theory. I'm not seeing the parallels.

I am a huge fan of the channel but the AI voice filter in your recent videos is extremely distracting to me. Your audio was already perfect! In this day and age we are all beginning to train our eyes and ears to pick up on what's real vs what's AI generated, and this filter raises my alarm bells unintentionally. Obviously I know you guys are a legit and trustworthy source of information, but it still gives me the creeps.
