The “Crisis in Cosmology” EXPLAINED

In the last few years, astronomers have witnessed a growing problem emerge. As measurement precision has increased, the hope was that this problem would abate, but instead it has only exacerbated. Welcome to "The Crisis in Cosmology". But what exactly is the fuss all about, and how much should be believe the sensationalism?

Written and presented by Prof David Kipping, edited by Jorge Casas.

As a barely average student in science and a slightly below average student in math, I am cursed with a love and fascination of cosmology and physics. It's sources like this channel that give me a hope of even the slightest understanding of it all and keeps me coming back for more.

[gregoryfilms]

Despite having no scientific background and often not understanding every explanation, I love this channel. It heightens my sense of wonder about our universe. Looking forwards to the next video.

[markholmes]

Well, that’s my bedtime pushed out 25 mins!

[darienwest]

Props to the editor for putting together these high-quality videos so frequently. Most people watch these videos for Mr Kipping's great explanations on these complex topics (and it can't be understated how great he does) but it wouldn't be the same without all the visuals.

[nckrad]

I wish you were my high-school teacher...I don't think I would have dropped out if you were. Your compassion for teaching science excites my childhood curiosity, and I just want to thank you.

[AdiusOmega]

What an eloquently spoken commentary on issues in cosmology. I've been noticing a lot of sensationalized videos on Youtube and it's good to have these more humble approaches to the topics. This is real science and unfortunately there's not many channels that portray these elements in this kind of way.

[martinconrad]

One small correction: I didn't click on the video because of the title; I clicked on the video because it's a Cool Worlds video and those are >always< fascinating and informative, regardless of the topic/content. Thanks for this channel and all you bring!

I'm 60 and was born in the middle of the Cuban Missile Crisis. Astronomy is now in a Golden Age, and I couldn't be happier. When I was a kid, the Apollo Moonshot was the world-changing paradigm, then we had Skylab, followed by ISS and the Shuttle SLS. Now, we got all these scopes out there plus tons of satellites, and various probes to other worlds . . . Golden Age! 🧠👀

I saw this notification at work and got a text from my son about 5 minutes later. We're about to sit down and watch after supper and I can't thank you enough for you and your team giving him such a rush for learning.

[mandelbraught]

Dr. Kipping, some of us clicked on the video precisely because we knew that you would bring evidence, thoughtfulness, and nuance to the question. 😊 I always appreciate your videos and, more importantly, your commitment to science.

[InturnetHaetMachine]

One of the clearest and thorough explanation I've come across. Thank you for posting this.

[tinetannies]

Professor Kipping, and all the marvelous minds like his, are glimpses of what humanity can be, what humanity is capable of, what humanity as a whole will hopefully, someday, rise to become

[FadingFire]

I really love your channel but it’s a double edge sword watching your content. You present things in such a great and enjoyable way makes it hard for me to enjoy other space related channels.

[bryandraughn]

I cannot express how grateful I am that you're going into such detail on these subjects.
There's an awful lot of videos out there that barely scratch the surface and leave it at that.
Too many in fact.

[markg]

I feel so smart as I follow Dr. Kipping through the various topics. Thank you Dr. Kipping for all of the patient and thoughtful detail in your presentation.

[elesdee]

No sensationalism. Just the facts. Thank you. I really appreciate the explanations of how we attain the information we do.

[frankelkjr]

Cool worlds never tell you what you WANT to hear or EXPECTING to hear; but it’s thought provoking brilliant all together

[dmsoundcollective]

i swear David .. you are so darn good at taking complicated subjects and explaining them in a way that is so easy to understand. I love what your doing man. Thanks you much !

[NastySeaweed]

Every crisis presents an opportunity to figure out something new ❤

[dementedfairy]

i have a b.s. in astronomy and it's always nice to find a channel that balances the technical and mathematical side of astronomy with the cool and exciting side that invokes curiosity in all of us
