M5 - A Laboratory in Space - Deep Sky Videos

[@HoyasBrasil]

Always a happy day when a new DeepSky video comes out ! :)

[@sandipmakhal1317]

Same here!

[@heaslyben]

It's so amazing what astronomers have figured out just by looking up! There's so much information to unpack, just constantly beaming down from the skies and literally hitting us on the head.

[@stevepecket2535]

And a Dr Becky bonus too !

[@reallifeistoflat]

i found this on my telescope tonight! it was my first "object" I've ever found and it made me quite emotional actually.

[@ln5321]

I just realized Becky's channel is now bigger than DeepSkyVideos. That's crazy.

[@Snakeyes244]

And I’ve been missing it all along :(

[@uvofsam]

47, 61, 72, 107, 108, just these five objects are left now to make the Messier playlist complete.

[@garyjorgenson8668]

I would have paid attention in class if I had a teacher like Dr. Becky…please keep up the amazing videos.

[@jonu7216]

Now this is a great video. To actually see you more like a scientist. Great subject. This tipe of video is much more interesting, much more informations and somehow you succeed to make it so simple for us to understand all this informations that ar the result of many years of hard work of many scientists. All of you deserve our full gratitude. Thank you Dr. Becky and please let all the science community know this.

[@PaulPaulPaulson]

65 million neutrinos passed through the thumb up I gave for the video!

[@alexv3357]

Every second!

[@ChrisTurchin]

Yes! New DeepSky episode, one of my favorite targets and Dr Becky. Christmas comes early sometimes 🤣

[@denisroym2110]

I wonder how many there are left to do???

[@ChrisTurchin]

@@denisroym2110 if they stick to the Messier catalog not many, but hey the universe is a very big place and they'll think of something.

[@user-cv7nd6sw3t]

Holy guacamole! I liked it how astronomy is once again not only the best testing device for judging by physical theories, but also an instrument for developing fundamental physics on quantum level!

[@2secondslater]

A Brady and Dr Becky Collab, best thing I have seen today.

[@FredPlanatia]

I very much enjoyed this contribution from Dr. Becky. What a great explanation of how scientists find new facts by building on what they already know (sometimes even in different fields). We stand on the shoulders of giants indeed! I guess one could now do the same analysis on other globular clusters to verify or improve the precision of this number? ~10-12 uB is just unfathomably small!

[@JansthcirlU]

Huh, I never would've guessed astronomers classify clusters by how messy they are.

[@Reactordrone]

But are the bigger or smaller number more messier?

[@kevinhanley3023]

Thanks Brady and Becky

[@ciurdypsyco]

Dr. Becky back in tha houuuuuse

[@Joel.Gonsalves]

Dr. Bec understood all you mentioned about WIMPS. I got lost at the new term magnetic biapole ! !!! Will come back again to check understanding.

[@avt_astro206]

awesome Video!! This My favourite Globular Cluster In Messier catalog :)

[@daveangels]

Finally 5's turn👍

[@vaderdudenator1]

Yay, she’s back!

[@y4lnux]

Amazing Dr Becky is Back :D

[@mikebaginy8731]

Wow, that was really interesting!

[@user-eh6th9wj5k]

Dr. Becky!

[@kennethhicks2113]

Excellent : ) Merry Christmas

[@protitikhan3861]

There's a neutrino lab called SNOLAB in Ontario, Canada. If anyone is interested. Yay, Canadian science 🇨🇦🖖

[@HenrikoMagnifico]

Please please make a video on Boötes void!

[@guyh3403]

Thank you so much!

[@ngawangsherab9724]

Hello Dr. Becky

[@francoislacombe9071]

If neutrinos don't respond to the electromagnetic force, how can they have a magnetic dipole?🤔

[@raphalex7]

They must have a dipole because of their weak interactions in beta decays.

[@garethdean6382]

It's not entirely true to say they don't respond to the EM force. As with gravity the effects can be largely ignored, but they're not zero. Indeed all known particles respond to all known forces through complex interactions of one sort or another. It should be noted however that the neutrino's moment is very, very small, the cluster result suggests it's on the order of a trillionth that of an electron's.

[@NeonsStyleHD]

Globular Clusters, great place for Civilisation to build an empire. Lots of Systems close together within easy reach. It's like the Empire builders Jackpot!

[@Rubrickety]

I'm deeply embarrassed to say I immediately thought "OMG Dr. Becky drew a willy!" I think I've been watching too many QI episodes lately. 🤦‍♂

[@physicstheoryofmetinaridasir]

I have predıcted with my theory and my formula 6.3 tımes greater speed of light which is measured as apparently inside of M87 black hole. I SUGGEST HAVING A LOOK AT THE FIRST PART OF MY THEORY AND MY FIRST FORMULA WHICH DETERMINES A LINEAR VELOCITY OF...6.3 TIMES GREATER THAN THE SPEED OF LIGHT, ETC. AND I TOLD WHERE OUR MEASURED CONSTANTS ARE ROOTED IN. We need to change the concept of matter that makes us imprisoned by all kinds of impressions and especially by accepting the vacuum illusion which it has been sitting comfortably in it

[@LeaderOfTheRedNinjas]

How can massless photon decay into a particle with (although very small) mass? Wouldn't that imply you're creating mass out of nothing, which is not possible?

[@francoislacombe9071]

The photons have energy, and that can be converted into mass, E=mc2

[@Astor_V]

You can "create" and "destroy" mass. For example, in nuclear fission, if you split an atom into two smaller atoms, the sum of the mass of the two smaller atoms is less than the mass of the original atom. The "missing" mass has been "converted" to energy, energy that we haverst in nuclear power plant. Now, for the truly interesting (and mind-bending) bit: Note that I put quotation marks everywhere for a reason: mass is not a true fundamental property of matter. Mass arise from the energy contained in a system. The more energy the system (for example the nucleus of an atom) has, the more massive it will be (or you can say: the more energy the system has, the more it will bend space-time). One crazy example of this is that if you take a spring, and compress it (adding potential energy in form of tension in the spring), you will make the spring heavier! But only very very slightly so (not really measurable tbh). Back to the atoms, there is potential energy held in the bonds between subatomic particles. When you split them, the resulting atoms do not have the same arrangement of subatomic particles, so they do not have the same combined mass. So the famous equation E=mc^2 is more that just how much energy you can get from mass, it's a true equivalence between the two (with a constant to balance the equation). But if energy is mass, why doesn't light have mass? Because it's a bit more complicated than that. But if you take light and somehow manage to get enough of it into the same spot, you can create a blackhole (which is then called a kugelblitz). Or if you manage to capture light in a box with perfect mirrors (not really possible in practice though), the box will be heavier with the light inside it than without.

[@max_kl]

@@Astor_V So if I lift an object up into a shelf it gains a tiny bit of mass, while I get lighter?

[@Astor_V]

@@max_kl I made a mistake, forgot to square c (33ng seemed way too much, and for a reason...). The correct added mass would be about 10^-16g = 0.1 fg. Still more than I expected though.

[@max_kl]

@@Astor_V Thanks! Though it seems like one of your comments didn't get through, maybe you included a link?

[@Muonium1]

What's all this that I've been reading about in the news then in the past few weeks about neutrinos being detected "for the first time" in a particle detector, when there's that picture at 1:50 from 1970 (which I'd actually remembered seeing before!)??

[@PaulPaulPaulson]

I think what's new is the way how the neutrino is created, not that one has been detected.

[@garethdean6382]

In this case it's the first detection of neutrinos *at a particle collider*. It's like being able to breed pandas in captivity; not the first time the subject has been encountered, but a milestone that makes their study much easier. With the new neutrino detector they'll be able to monitor the neutrino production of the collider and look for new physics there.

[@Muonium1]

@@garethdean6382 but.....i mean.... that bubble chamber the picture is of from 1970 was also presumably connected ya know....to a particle collider. I'm guessing SPS or something. I still don't get it.

[@Casowsky]

@@Muonium1 That was probably naturally occurring neutrino flux, not created by man.

I don't think I've ever understood a diagram that I've seen in a scientific paper.

[@SharpAssKnittingNeedles]

This is awesome, but given we now know that some globular clusters are remnants of paleo satellite galaxies, do we know for sure that this one is is actually a single generation of stars? The CMD seems to indicate that but just playing devil's advocate 😂 surely the peeps who wrote this paper had data in there to indicate this, all same metallicity or whatever
