"Until next time, on the Outer Limits"

Happy 2023 y’all

that audio representation of various pulsars really made the idea of them spinning so fast quite frightening.

I'm really curious how many episodes of space time have ended in the words "Space Time".... It's like 95% of them I bet? I love your contributions to this channel, Matt.

This is the one episode where you have to watch more than once to understand most of it.

When you’re so early there’s no subtitles yet

that pulsar gravity-meter idea is spectacular.

Words cannot express how much I value PBS. You are by far the best network, ty all I've learn so much with your channels, all of them❤️😍♥️

lying down makes it so the rate of aging of your head and feet are closer or the same. changing the altitude changes the rate. If you want to reduce the rate of the aging, the thing is to change the altitude.

This is effing amazing! This is one of the top discoveries but I did not see coming or in general. This is awesome I hope we can study this more! This is literally the entire fabric of our entire Cosmos

this is the best astrophysics channel on YT. Period

This is amazing that we are able to use these remote resources to unveil the very nature of Spacetime as we are inevitably traveling thru that same field being measured on the solar, galactic, and universal scale. The maths behind the computational variables to simulate these structures as accurately to one one-hundred millionth of the length of the diameter of a proton is easy to say, but mind numbing to comprehend.

Though I'm no dunce, I'm simply not sharp enough to be in scientific fields like astrophysics and quantum mechanics. I'm so glad that there are people who are, and who have an insatiable thirst for knowledge, and a curiosity to rival Pandora! I'm glad people are asking questions that would allow the whole of humanity to benefit from the answers!

Hope the mystery of “The Great Attractor” is some what addressed with the advent of this new method of observation!

How large ARE you?!?? Or should it be 'small'... >.

You did an amazing job of explaining all of this.

this has to be my favorite you tube channel, keep up the amazing research you do.

How about this: Dark matter is the interaction (or drag) between these gravitational waves and regular matter. That's why there "appaears" to be more dark matter around galaxys.

One comment i could make is that if both the gravitational background and dark matter have the same effect, that means that they either both or only one (or none, e.g. something we didnt expect is creating the effect) exist. If they both have a gravitational effect then there could be less dark matter than we suspected. How would we differentiate between the two?

We live in a jello called spacetime, it has two sides, but it is easier to think that we live in the outside where the spacetime covers a sphere-shaped object. If you are inside or outside it doesn't matter you will always see what it is easier for your brain to understand from your point of view. Gravity and dark matter are the same thing. Space has 3 dimensions, but so does time... At the convergence point past present and future become height width and depth. The convergence point we call it singularity. White holes do not exist, superluminal speed would rip the spacetime jello, black holes absorb matter and put it back in the circle, destroying informations such as a filter breaking entanglement. (My fictional explanation about universe... I didn't figure out what happens outside the spacetime jello yet, and the Fermi paradox...) Don't make fun of me this was for pure entertainment! Covid gave me a lot of time to work on stupid ideas!

@@Desirion83 haha i love it, imaginative and curious. By no means stupid, nothing involving pondering is stupid. So how did you arrive on the idea of spacetime having two sides? Its interesting. Is the one side all the information encoded on a 4D event horison and the other side pure nothing? Like not even a vacume, just a non existence. This would explain the fundamental nothing-everything idea which underlies any reality, what is the idea of something, withought the idea of nothing to describe it.

@@thanasisathanasiou6362 ​ @Thanasis Athanasiou The two sides purely exist to balance out the other one, none of them can interact, like two sides of a coin. Anyway everything that you can imagine is possible. Mine is a romantic approach to philosophy more than science! To answer your questions; no information exist, at every soft reset. The idea behind it is that we cannot understand the big void behind the spacetime-jello, and gravity doesn't have a counterpat in quantum physics either, so gravity has a dark side too. In my fictional universe Blackholes are safepoints cause light could be very dangerous. Like me driving a Lamborghini... I know it doesn't make sense but it is a lot to explain...

Do Gravitational Waves also warp time? How much? Could they warp space or time without warping the other one, or are they like electric and magnetic waves that always seem to come together?

@castonyoung7514

Yes. Gravitational waves are a warping of spacetime, and since space and time cannot be so easily separated the waves do necessarily affect both.

the audio example was very interesting! thank you for posting it!

Just when I start to lose all hope for mankind I hear a story like this and it restores my hope.! Good job

Question: Would I feel such a gravitational wave while sitting relatively close to a merger? Just like I feel, with my gust, the sound waves from a big loudspeacker.

@ngcastronerd4791

What you are feeling is the soundwave propagating through your body cavities. That soundwave is relatively weak compared to the levels of energy discussed here. You would feel something all right.

@garethdean6382

Generally to be able to feel the gravitational wave you'd need to be close enough that the direct warping of space would be lethal -in essence standing so close to the speaker that its vibrations hit you.

sorry, layman's question: Does the gravitational wave impact the search for Quantum gravity, graviton and other areas like that?

That's a definitive "maybe". Most likely it will be like the LHC is to supersymmetry: ruling out a specific subset of possible theories but not really giving us sufficient direction to know which of the remaining theories is correct (or at closest to correct). Of course its always possible that there will be a silver bullet hiding among that particular data set. That's never completely out of the question. Its just fairly unlikely given the low resolution measurements we'll see from this technique. 100 data points spread around the entire sky just won't be sufficient to see much in the way of fine detail. But that's OK in itself. Fine detail images generally lose the large scale detail so we need a bit of both to really understand everything. But extremes of physics where we tend to find new stuff is (almost) always at the high energy end of any spectrum, and there's little reason to believe that will be different for gravitational waves. Again we don't _know_ that (think of temperature where both the low end of the spectrum is much more interesting in many ways) so as noted a silver bullet isn't entirely out of the question. I'm just not personally expecting one. Still waiting for LISA :D.

Another great episode. You are such an inspiration. Can't wait for the next one 🙂

WOW. It never ceases to amaze me how incredibly fast neutron stars spin and just what it would be like to be able to see these places. It's actually pretty absurd that something like a pulsar exist that all but that is why I love science so much
