The idea that the universe is not the same everywhere has been flying under the radar for the last fifty years or so, and a new paper details a fresh perspective on this idea. According to the new paper, the decay of axion domain walls could explain dark matter and some unusual gravitational waves. Let’s have a look.

It’s all more weird than we could possibly understand

So the universe is growing by mitosis? Asexual reproduction. As Spock would say “Fascinating “.

The universe is a giant cat and that’s why people are obsessed with cats.

Another interesting but likely untrue idea. But it is actually a lot of fun.

With how hyper-advertised everything is these days, I was expecting a squarespace advert when you mentioned domains

I can only love Sabine's brutal skepticism

As a Blue eyed American living in China my eyes often the cause of staring due to their rareness it this part of the world where brown eyes are the norm. As is jet black hair

Damn, domain expansion just took on a whole new meaning

[@vin9235]

I had the pleasure to be lectured by one of the authors of the paper. It is very cool to see Sabine covering one of his papers. Thank you for your videos!!

Just wondering ... if these domains have different names ... do we need an intergalatic domain-name-system then?

[@ZappyOh]

As the programmer of the Universe, I'm especially proud of black holes.

[@zdzislawmeglicki2262]

I think, when the domain walls disintegrated they left behind… matter, normal baryonic matter, which is why we have these huge cosmic structures, walls made of galaxy clusters, and why they formed so early.

[@aaronjennings8385]

The galaxy projector sounds good.

[@yeroca]

So according to this, maybe both Axions and 1nm primordial black holes comprise dark matter? I would have thought BH's of that mass would have evaporated already. I seem to remember reading about what a very small black hole would do if it were to collide with the Earth, and the answer was kind of surprising - not that much.

Sabine, I find your TH-cam channel to be extremely interesting and funny at the same time, there’s not a whole lot of Matt there that can do that and still make sure you understand things that are complicated to understand. Thank you very much for your channel, I appreciate it and watch it every single day.
