The idea of a particle with a de Broglie Wavelength of lightyears breaks my preconceptions about quantum field theory, and I love that.
@whatdamath
Something that's important to remember is that axions are originally a prediction of another mystery - they are supposed to resolve the strong CP problem in quantum chromodynamics. Or basically why matter even exists. There is no better explanation at the moment that explains this oddity. So there's a super high chance that they do exist There was a study this year that suggested we can find axions by using extremely powerful accelerators with ionic particles inside in order to force interaction with incoming axions that would result in observable effects. Something that could be achieved in the next decade or so assuming there's interest

I love when previous episodes come together into an episode like today's. Awesome job Space Time crew!
@DavidEvans_dle
Really love how this channel explains the possible physics behind the cosmology observation we're currently seeing with new discoveries.
@adamnagy4544
Aww I missed this type of "cutting edge", deep cosmology/quantum theory topics. I love that <3
@mrgalaxy396
This has been one of your better episodes recently. Great stuff, can't wait to hear you guys cover the gravitational wave announcement that's due tomorrow.
@WestOfEarth
Simply the best explanation of axionic dark matter I've seen yet! Thanks Matt
@Jondiceful
I really love this idea and am very grateful to Spacetime for introducing me to it. It's a wonderfully weird solution that somehow feels intuitively "right" in some way. Other dark matter solutions always leave me feeling like we are missing something that should be obvious. There's just something beautifully elegant about the idea of quantum waves that are light-years across. Whether or not it is proven to be correct, it has a beauty to it to rival the greatest works of art. It's both simpler and weirder than Ant-Man's so-called quantum realm, while still being consistent with known reality. If Axionic Dark Matter ends up being wrong somehow, I hope and suspect it will be because nature is even more beautiful and weird. This is one mystery in which the journey is more exciting than the destination, and I am lucky to be along for the ride.
@bloodsin28
This may be one of your best epis9des ever. Not just the subject matter (which is amazing) but also the overall delivery / production.
@NeonsStyleHD
Best Science Channel on YouTube! Thank you. Seems I like my Dark Matter Fuzzy rather than Cold. :)
@biotek1727
Congratulations, your way of explaining things is ..super fluid. (I guess this sentence works in English, as well as in French).
@Starfallenn
Your videos are on are strange border between simple enough to understand as someone with little scientific knowledge, and advanced enough to discuss complex things like string theory or quantum mechanics. Your work is very interesting and absolutely awesome. Thank you Matt!
@Stogger1459
I mean despite the fact that I get my QM knowledge here( of course in another lifetime I would love to be proficient in the sciences) this has pretty much been the channel that has made me fall in love with physics. I’m curious though, is there going to be a video on the recent developments on Sagittarius A? Black holes are so interesting and getting to understand what’s going on and what it means would be great. Thank you again Matt!!
@cookicha
First time I ever immediately re-watch a Spacetime video, in many years! Fascinating! I love this theory, it's so beautiful!
@louise1967
It surrounds us and penetrates us; it binds the galaxy together.
@ToddNorthrop
Thanks for such a great video! When you got to the explanation of dark matter as a superfluid my mind was blown. You guys do such a great job of opening my mind to new concepts, and you deserve major props for the unapologetically technical discussion.
@EdyGavrila
Love it when my phone pings with another PBS-ST video
@anthonyalfredyorke1621
Another great show Matt , most of the subjects are way above my pay grade but they are fascinating & at least I'm getting some of it . I love your live streams , keep on Keeping on. PEACE and LOVE to EVERYONE.
@InternetStranger476
Your description of the de broglie wavelength helped me to understand how particles become waves and even quantum fields
